Cyanide: The Poisoner's Weapon Of Choice| The New Detectives | Real Responders

investigators on the scene of a drug overdose find themselves matching wits with a serial killer [Music] something in the water has killed an office worker in arizona her colleagues are lucky to be alive now detectives must decipher a mass poisoner's chilling agenda [Music] when a healthy woman is found dead in her bath investigators know she didn't drown on her own chemistry confirms there's more here than meets the eye but can it lead them to the killer our material world is built on just 113 kinds of atoms their combinations can produce a world of good but in the wrong hands they're just bad [Music] medicine [Music] at 10 a.m on saturday december 10 1994 detroit police arrived at the hotel suite of lowell and roberta amos just one block from police headquarters [Music] lowell had reported that his wife had overdosed on cocaine and was dead police found a cocaine straw and playing card in the nightstand but no signs of the drug mr amos said he panicked and flushed it when he woke to discover that his wife was dead to police it seemed that amos had done more than dispose of the cocaine the room was neat as a pin practically scrubbed clean the bedding where the victim lay however was thoroughly soiled and smeared from side to side so how much more you got to work on there though the victim wore no makeup the pillowcase was saturated with cosmetics when the medical examiner removed the victim it was clear that she had been dead several hours before police were notified suspicions arose that there was more here than amos was telling homicide was called in and lowell edward amos gave police his account of what happened that night roberta amos was last seen with her husband in the hotel suite of his business partner norbert crabtree and his girlfriend darcy smith the event was the company christmas party and executives were given suites at the hotel so they wouldn't have to drive afterward though lowell and roberta amos were unofficially separated she agreed to accompany him to the party afterward crabtree had invited lowell and roberta to his suite to continue celebrating they stayed until 4 30 a.m told police that after they returned to their suite they made love and started doing cocaine [Music] lowell fell asleep while roberta continued using the drug he said that she had sinus trouble and couldn't snort it so she found other ways to get it into her system she must have overdosed while he slept because drugs were involved he was afraid to call the police right away and flushed the remainder but that didn't adequately explain why he waited so long to call authorities swabs taken from the victim's vaginal area tested positive for traces of cocaine other than that there were no other external signs of the drug that was strange internally she had 14 times more cocaine than is normally seen in an overdose she died before half of it was broken down in cocaine poisoning death is preceded by violent convulsions forensic chemist phyllis goode believed that amos could not have shared the victim's bed and slept through that in fact he probably couldn't have fallen asleep at all well cocaine is a central nervous system stimulant and has the effect of keeping a person awake and full of energy it's not the usual case that a person would go to sleep right after they've used cocaine get this sheet off of here that should be the last thing lowell amos did his best to clean up the scene but his story of his wife's death just wasn't washing now investigators had to prove that he killed her at the michigan state police crime lab phyllis goode examined the bed sheet to determine what caused the stains nothing in lowell amos's scenario could have accounted for their condition because the victim's body was so clean they suspected that lowell had washed it before he called police investigators hoped some evidence remained in the linens the sheet was treated with chemicals to more clearly reveal the stains portions were cut out and labeled because the stains occurred on virtually all portions of the sheet good took samples from all areas [Music] the same process was repeated with the pillowcase to see if anything besides makeup could be identified the pattern of the smudges suggested that the pillow wasn't simply wiped across the victim's face what appeared to be a lipstick or characterized as lipstick is that there is an imprint on the pillowcase of what had appeared to be imprint of teeth teeth marks and they are located in this area under the blue spot the blue coloration is from laboratory testing people at the christmas party told police that they had seen the victim wearing makeup when her body was found she had none but the pillow revealed she went to bed wearing it apparently she had bitten hard on the pillow or the pillow had been pushed hard into her face before she died a bruise on her nose suggested that it was pressed with tremendous force the samples from the pillowcase and sheet were sent to the state police crime lab for analysis investigators awaited the results meanwhile police interviewed norbert crabtree and a business associate he admitted that on the day of the death lowell amos had phoned his room at 8 30 a.m saying he needed help he wasn't specific crabtree who was awakened by the call didn't arrive until 9 30 with another business associate lowell told them that roberta was dead and gave them a bag to hold for him detective patrick henahan was assigned to the case the items were described as a a wash cloth from the hotel linen that was stained and very foul smelling a sport coat and a syringe without a needle in a small leather type carrying case amos collected the items from his friends later investigators never recovered them to determine what happened they had to rely on the evidence at hand namely the bed sheet and pillowcase the lab results showed traces of cocaine throughout the sheet but that was all the results of the test were the lack of urine or presence of urine the lack of semen or seminal fluid and the only thing that was identified in the brown areas was characterized as vegetative matter the identity of the brown stains was inconclusive they shed no light on what happened only deepening the mystery the fact that the cocaine was also smeared around the sheet and tucked under the sides merely told investigators what they already knew that lowell amos had manipulated the scene either out of fear of being blamed for contributing to his wife's death or to hide the evidence that proved he murdered her [Music] as investigators mulled over which it could be lowell amos's past began to catch up with him it seemed that amos may have been a real lady killer as word spread of the investigation into the death of roberta amos investigators in detroit learned much about the suspect lowell amos he had an unsettling history with women two came forward who said that before he married roberta they met him at a bar had drinks with him and woke up in his apartment with no recollection of how they had gotten there other women reported becoming violently ill after being intimate with him they claimed they'd been drugged but the most astonishing revelations were yet to come i began to receive phone calls from my relatives received phone calls from doctors private investigators police officers friends from as far away as oregon most of the information that was coming in and was in regards not just roberta mowry amos but also her husband lowell amos i was advised that this was not his first wife to die at a young age under suspicious circumstances none of the deaths were considered criminal at the time but times had changed and the death of roberta amos shed new light on old events in 1994 michigan amended its rules of evidence past incidents could now be entered into a current criminal trial if amos's dark history could be shown to have some bearing on roberta's death the case against him would be the first one tried under the new rules nancy westfeld assistant prosecuting attorney for wayne county michigan was brought in to see if the rules applied to lowell edward amos if somehow we could demonstrate what mr amos's real intentions were by looking back and looking at these other women looking at their lives looking at their deaths looking at how ed amos had treated them and in the end what he did to them as they died the first mrs amos sandra amos died in 1979 at age 36. the couple had been married nine years according to lowell sondra mixed dalmane a sedative with wine and must have collapsed and hit her head on the bathroom counter though sandra's autopsy revealed traces of dalmaine and alcohol in her system it wasn't enough to incapacitate her most of the drug was still in her stomach undigested she showed only a small abrasion over her eye not enough to knock her out or kill her her cause of death was undetermined the circumstances were not suspicious enough to launch an investigation however in hindsight one detail stood out after saundra was taken away a neighbor walked in to find amos burning something in the fireplace he told the neighbor it was his wife's clothes bloodied from her accident but whatever killed sandra left no bleeding cuts or lacerations there was no blood at the scene and she was taken away in the clothes she was wearing when she died so the question became for us what was that burning in the fireplace and why was it so important did he get it destroyed before anyone saw exactly what it was lowell edward amos received 350 000 as beneficiary of his first wife's insurance shortly after came wife number two carolyn amos lowell's mistress while he was married to sandra you are irresponsible their marriage was rocky the friction point was the huge insurance policies lowell kept taking out on his new wife when he would not drop these policies in 1988 carolyn threw him out of the house [Music] he went to live with his mother mary tolls age 76 he stayed with her approximately two weeks when she became ill and was brought to the emergency room her doctor commented that it appeared as though she was drugged but none of the medications prescribed to her could account for her disorientation at the hospital she began to recover and was sent home carol and amos phoned mary tolls every day to check up on her a few weeks after tolls returned from the hospital carolyn's call was answered by lowell who had just discovered that his mother was dead apparently for several hours carolyn raced over to the house with a friend to find lowell packing his belongings into his car he didn't want anyone to know he was living there lowell inherited more than a million dollars from his mother's estate [Music] no autopsy was performed on mary tolls because of her age carolyn let lowell move back into the house nine months later in the spring of 1989 carolyn too was dead [Music] according to lowell's report to police he brought carolyn a glass of wine while she was in the bathroom blow drying her hair [Music] when he went to check on her later he found her dead on the bathroom floor eerily like his first wife it took a while for medical assistants to arrive at their secluded house by then it was too late to revive her amos suggested that she may have been electrocuted from the blow dryer an examination of the cord showed that it had been cut but carolyn wasn't electrocuted her cause of death was never determined though the case was never pursued the medical crew found inconsistencies at the scene the wine glass was missing found later rinsed and in the dishwasher and the position of the victim's body suggested that she had been moved her pajama top and her pajama pants were up at the ends both at the bottoms of her feet as well as at her waist hitched up as it were as if she had been moved certainly not in a position they would have been if she had crumpled to the floor lowell received 800 000 from his second wife's insurance policies for investigators lowell amos was the kiss of death to the women he purportedly loved detective henahan believed it had to be more than coincidence i have had three close relatives of mine that have died i've never been within 500 miles of any one of them when they died lowell amos was in the company of all four of these persons when they died he benefited emotionally and financially from their deaths like the other deaths roberta amos lay dead for some time before authorities were notified ed wanted to make sure that each of these women was beyond help he wanted to make sure none could be resuscitated none could be medically brought back to life because he wanted all of these women dead though roberta amos marriage was failing she enjoyed a measure of professional success shortly before her death she had purchased a house with her own money her plan was to legally end her marriage to lowell and make a fresh start though lowell edward amos had no financial stake in her death investigators believe that he couldn't stand the idea that she had rejected him the similarities between the death of roberta james and lowell's other wives was enough to expose him as an opportunistic serial killer who murdered for money or just to end an inconvenient marriage based on the collected evidence and the ghosts from his past authorities had what they needed to arrest him for the murder of his third wife roberta amos from the photographs of that night roberta mowry amos looked happy she looked like she was having a good time she must have had hope for the future that she shouldn't have at trial the prosecution presented an account of the last night of roberta amos's life [Music] after leaving norbert crabtree's suite the couple went to their own room where lowell dissolved a large quantity of cocaine and water [Music] he was somehow able to incapacitate the victim once she was subdued he used a syringe to administer the lethal dose of cocaine then perhaps if she was convulsing he smothered her with a pillow he then scrubbed the body and cleaned up the crime scene as best he could before calling crabtree to dispose of the remaining evidence for his crime lowell edward amos was sentenced to life in prison without parole lowell amos escaped suspicion through the subtlety of his crimes but his past and forensics caught up with him at last other killers are more obvious in their methods though they may be just as difficult to catch monday march 24 1986 started out like any other monday by 8 30 a.m the employees at the transamerica title insurance company in tempe arizona were already at the office their weekend's a fading memory like her co-workers 46 year old julianne williams eased into the day with a trip to the break room the coffee was on but she preferred a drink of cool water [Music] [Music] just one sip told her something wasn't right [Music] should i come with you she immediately didn't feel well and headed to the ladies room she didn't know it but she was beyond help when julie williams was found in the ladies room shortly before 9 a.m she was in cardiac arrest [Music] by the time paramedics arrived she had slipped into a coma [Music] they rushed her to the hospital something was in the water while the co-workers discussed what had happened one of them diane harry was on the phone to her husband she was more concerned than the rest because something similar happened to her just a few days before [Music] by the time police arrived to investigate diane harry's husband louis harry was already there looking for what might have poisoned the water but it wasn't just a cooler that was tainted [Music] tempe police sergeant mike palmer led the investigation i detected an odor within the room upon examining almost every cup or container of any type and the coffee pot that was in there i could see that there was some type of substance in almost all of them at that point we decided that someone had purposely placed whatever this material was in these containers in order to injure people the office workers were lucky that no one else was hurt but julie williams after lingering in a coma was not so fortunate whoever spread poison in the break room was now a murderer samples of the unknown poison were taken for identification police dusted for fingerprints but no suspicious ones turned up [Music] the police interviewed the office workers diane harry told detectives that on the previous friday she became ill after taking a sip of scotch at home that saturday a cup of tea affected her the same way she remained ill the entire weekend she barely could get out of bed uh and she told me that the smell uh of the substance that she had inside her house in phoenix was pretty much the same as the smell that was in the substance that was in the break room she was concerned that she was the poisoner's target which is why she called her husband to the office when julianne williams became ill police talked to lewis harry he too was worried that someone was trying to poison diane harry he said he'd been receiving threatening letters from the abusive boyfriend of a woman he'd helped perhaps this was his revenge lewis was sent home to collect the letters along with the scotch bottle and tea kettle so they could be analyzed meantime police collected the security cards that every employee needed to enter the building investigators suspected that whoever planted the poison did it sometime during the weekend a check with the security company showed that only one security card had been used that weekend at 10 18 on saturday morning it belonged to diane harry when i confronted mrs harry about her card being the only one used during the weekend she denied having used it the only thing she could tell me was that she did not know where it was at other than the fact it should have been in her purse because that's where she'd placed it the last time she'd used it the card was in fact in her purse monday morning when she went to work she insisted she'd been bedridden all weekend and never left the house it says that you checked into the office so far all the evidence pointed to diane harry but was she the prime suspect or the intended victim it was too soon to tell while detectives were trying to identify the criminal scientists were trying to name their poison samples from the office water cooler coffee creamer and sugar bowl along with the tea kettle and scotch bottle from the harry's house were brought to the arizona department of public safety crime lab where they were analyzed by supervisor jim timmons he knew that the poison was a fast-acting white powder that helped him narrow down his tests i really came up with a pretty short list of poisons that could have resulted in the information that i had heard about the case and the short list was arsenic strychnine or cyanide investigators applied a series of tests to the compound to narrow the list even further and to check and double check his results an ultraviolet light was shown through a solution of the unknown substance and measured on an apparatus called a spectrophotometer strychnine which absorbs uv light would give a reading arsenic and cyanide which reflect uv wouldn't register the unknown substance gave a reading on the spectrophotometer proving it wasn't strychnine [Music] they then performed a test for arsenic samples of the substance were dissolved in acid and a copper wire was placed in the resulting solution if arsenic were present it would attach to the wire and turn it black no arsenic was present the unknown poison in the office and in the harry's home was most likely cyanide to be certain timmins used a commercial kit for identifying cyanide it's actually a very simple test but it involves some pretty complex chemical reactions ultimately what happens is a red dye is formed if you have cyanide and you test this on a paper strip that you drop into a solution and in this case it was positive indicating cyanide was present to remove all shadow of doubt timmins further confirmed his results with a gas chromatograph mass spectrometer [Music] the substance was sealed in a test tube of acid if it was truly cyanide it would form hydrogen cyanide gas like a mini gas chamber the gas was drawn off and injected into the apparatus which confirmed that the cyanide gas was created [Music] the battery of tests would provide essential forensic evidence for the courtroom if the poisoner was ever brought to trial timmons was not done yet [Music] cyanide most commonly appears in two forms sodium cyanide and potassium cyanide both are equally lethal a technique called energy dispersive x-ray analysis allowed him to simultaneously check for various elements in the compound he found potassium samples from the office and from the harry's home gave identical results both were potassium cyanide the water cooler alone had enough cyanide to kill 150 people the killer had set his or her traps in both places and cast a wide net to catch one victim diane harry was either lucky to be alive or trying to disguise her role as the poisoner the questioning continued i questioned miss harry about her husband's ability to get her electronic card that allowed access to the building and she stated that he could have but as far as she knew it was in her purse she indicated to me that she was not sure where he had been on that saturday morning from approximately nine in the morning until 12 30. if diane truly didn't use her security card on saturday perhaps her husband did he was the only other person who would have had access to it he said he was running errands that day he couldn't account for his exact whereabouts at the time the card was used to enter the building he insisted that the killer was the jealous boyfriend of the woman whom he had helped he had the threatening letters to prove it while the documents were being examined investigators looked further into lewis harry's movements their quest took them to a convenience store across the street from his wife's office building we are able to find an individual who actually observed a black male subject driving a blue sports car which is what mr harry drove enter at the approximate time that his wife diane harry's key card was used to open the door to the business that gave investigators the leverage they needed to serve a search warrant on lewis harry's office he worked in the athletics department of a community college in the wastebasket detectives found a label from a chemical supplier some white powder on a bookshelf and a small plastic knife also speckled with powder that was later identified as cyanide the cyanide found in his office didn't prove he put it there a defense lawyer could argue that whoever tried to poison his wife also left cyanide at lewis's office but the next discovery would be much more difficult to explain away also there was a legal pad that was that we found that had uh the handwritten version of the threatening letters that had been mailed him the last few of the threatening letters the pad and a box of envelopes were brought to the department of public safety where they were analyzed by forensic document examiner bill flynn in many ways handwriting is even more individualistic or individualizing than dna for this reason there are groups of people in society like monozygotic twins or identical twins who do in fact have identical dna characteristics however in forensic handwriting identification we've never found any two people that have exactly identical handwriting characteristics the handwriting on the letters was compared to samples of lewis harry's writing taken from business forms at his office and that the department of motor vehicles flynn was able to say that harry had actually written the drafts of the two threatening letters he claimed were sent to him after he perfected his wording longhand he typed the letters and mailed them an analysis of the envelopes proved it the letters that harry presented to police were sent in slightly defective envelopes the unused envelopes in the box confiscated at harry's office bore similar flaws flynn exploited that weakness to strengthen his case a defect of the type that we had seen in the in that envelope was actually rare the reason it was rare is that it would be severe enough to shut down the line they would actually have to clear the envelope making line and restart it in order to to clear that type of error for lewis harry the defective envelopes were especially incriminating [Music] but they didn't seal his fate forensics had proved only that he'd sent himself the threatening letters now it had to prove he'd carried out his poisoned promises [Music] to tie lewis harry to the poisoning of his wife's office detectives needed to prove that he'd purchased the cyanide they went to the chemical company listed on the label found in his office and obtained their sales records the clerk recalled selling potassium cyanide to an african-american male on the receipt the name was charles holly an african-american man named charles holly was contacted he told police he'd never purchased cyanide his signature wasn't close to the one on the receipt lewis harry was asked to give a handwriting sample we'd asked louis harry to write the name charles holly he did do that and from the earlier writings that i had in my office and now with the new exemplars i was able to identify louis harry is actually writing the name that was all detectives needed to make their case against lewis harry [Music] according to the prosecution scenario lewis harry did receive threatening letters from the ex-boyfriend of the woman who was secretly harry's new lover the letters gave harry the idea to write his own more threatening letters and send them to himself implicating the ex-boyfriend he practiced his poison pen letters before typing them [Music] when his attempts to poison diane harry at home didn't work he secretly borrowed her security card sneaked into her office and poisoned everything he could find in the break room he was a frequent visitor to his wife's office so his fingerprints weren't suspicious but when his wife called him after julianne williams was poisoned he wasted no time coming to the office to leave even more prince while pretending to show concern diane harry's trust in her husband was steadfast to the end throughout the investigation she refused to believe that he could be the poisoner though she remained unconvinced by the evidence the jury saw it another way for the murder of julianne williams lewis harry was sentenced to life in prison for first degree murder plus 105 more years for attempted murder he's serving at least 95 years [Music] even after lewis harry's conviction diane harry swore that he was a victim of circumstance her feelings changed a year later when her brother uncovered the box of cyanide hidden in the harry's attic for every criminal who thinks he's committed the perfect murder there's a team of dedicated investigators out to prove him wrong in albuquerque new mexico on the morning of march 28 1990 six-year-old james woodward called his dad because he couldn't find his mother the woodward's had been separated for three months david woodward told his son to go to the neighbor for help [Music] the boy told the neighbor that he thought his mother was locked in the bathroom but he couldn't hear any sounds inside she followed james to the bathroom go call 9-1-1 quick she jimmied the lock and found 30-year-old deborah woodward submerged in the tub an odor like solvent hung in the air [Music] the paramedics and deputy medical examiner arrived to study the scene the victim showed no contusions or abrasions to suggest that she slipped in the tub why she may have drowned and there was no explaining the odor permeating the room [Music] according to forensic pathologist sparks vesey the situation was peculiar from the start a normal healthy adult generally does not just drown in four or five six inches of water in a in a bathtub we look for some explanation for that at autopsy blood was drawn and screened for alcohol which might have contributed to the drowning while a body is wet injuries may be obscured but as it dries more is disclosed as the examination continued a chilling revelation sprang from the victim's own lips the examination of the inside of the lip showed injuries inside the lips which were suggestive that something had been forcefully placed over the decedent's mouth and pressed into the teeth cause causing injuries of the inside of the lips the case was looking more like homicide by the minute the blood work showed no alcohol in the victim's system but it did reveal a volatile substance similar to acetone or nail polish remover [Music] a sample of the blood was placed in a gas chromatograph to better identify the substance it turned out to be ether in fact every tissue in the victim's body was saturated with it ether is a volatile liquid that can depress the central nervous system depending on how much is inhaled it can cause dizziness unconsciousness or death by respiratory failure it was once a common form of medical anesthesia was replaced by more predictable and safer methods ether can be produced in the body by the breakdown of some other chemicals or drugs the victim might have taken chief toxicologist ronald backer didn't believe this was the case but the fact that it was distributed in all tissues and in very high concentrations was a good indication that this was a significant substance that was not an artifact that really was involved in rendering her unconscious the victim had enough ether in her system to knock her out but it was the drowning that did her in this was no accident [Music] while investigating the suspicious death of deborah woodward police learned that she was separated from her husband david even so she shared her house with him until it could be sold in an unconventional time share arrangement their three sons stayed at the house while deborah and david took turns living there and sharing child custody the plan was designed to create some stability for the boys but the friction between the couple laid just below the surface deborah had a restraining order preventing her husband from approaching the house while it was her turn to live there none of the couple's problems escaped the scrutiny of albuquerque police detective damon fay who was investigating deborah woodward's murder now i had to explore every part of her life and i had to just open up all of the canisters of her life one of them was her diary particularly ghoulish to read because i could see the build up of heading towards marriage with david all of her excitement that goes along with that the new marriage the early years of it then the deterioration of it in her diaries which debra entrusted to a friend for safe keeping she recounted the physical and emotional abuse that she endured slapped me around in the bathroom messed up my clothes broke things so much anger hell absolute hell after the separation debra tried to get on with her life she began dating and was starting a serious relationship but her husband was jealous and she was fearful of what he might do according to investigator faye she counted on her neighbor a retired police sergeant to keep an eye out for her especially at night and had actually come to the rescue of deborah on several occasions where she felt david had been skulking around or she heard bumps in the night wanted him to sort of investigate it he would walk across the street and take care of things walk around her house on occasion so he had sort of passing knowledge about the domestic turbulence the neighbor told police that six months earlier deborah had noticed something odd in her car he offered to take a look and discovered that david an electronics expert at a garage had planted a tape recorder in her car that switched on whenever the engine [Music] started [Music] he'd also bugged the house in telephone lines there was nowhere in the house where she couldn't go that he could overhear whatever conversation was taking place he could then take these tapes away and dissect them go back through them listen to them and that would just infuriate him david was doing everything in his power to keep tabs on his wife while deborah devoted all her strength to making a clean break it was a rough game of tug-of-war and it looked like something had finally snapped [Music] the neighbor told police that several days before the murder he saw david woodward dismantling the motion sensor spotlights he'd recently installed around the perimeter of the house he thought nothing of it at the time now it seemed too convenient woodward had the motive and opportunity to kill his wife but where was the weapon [Music] though ether was obviously used to incapacitate the victim it was the impurities in it that drew the focus of investigators the killer had used impure industrial grade either like the kind used in carburetor starting fluid considering that david worked in a garage that seemed a likely source if they could link him to a brand of starting fluid with the same contaminants in it they'd be that much closer to closing the case they tested every can they could find with no matches as investigators were busy tracking down the ether one of woodward's co-workers contacted police oh man there's so many people that a woodward had talked about getting away with murder by using a volatile substance like ether woodward claimed it would be untraceable he was very detailed about it but the co-worker wasn't paying close attention and what you do is you spray it like a rag based on this lead and the other circumstantial evidence gathered at this point police obtained a warrant to search the garage how long did you stay there they confiscated an assortment of chemicals including more cans of carburetor starting fluid we never did find any brand uh that was perfect but we found some that were very close and ones that we would we could put a star next to as the possible source of the of the ether in the deborah woodward uh blood sample but in terms of evidence it was enough david woodward was arrested based on the evidence police reconstructed the murder of deborah woodward it was the victim's habit to take a late night soak after putting the children to sleep while she was getting ready for her bath david used his key to enter the house he had already dismantled the motion sensors so he could sneak into the yard under cover of darkness once in the house he saturated a rag with starting fluid overpowered his wife and caused the marks seen at autopsy as the victim lay unconscious david pushed her head below the water he thought the ether would evaporate and with it would go all evidence of a crime the truth of the matter is that dead men tell plenty of tales if you have a competent team of forensic investigators which include the police at the scene the uh autopsy people taking the samples and the laboratory that analyzes the samples david woodward received life in prison for murder in an additional nine years for aggravated burglary for entering the home and battering his wife no poison is perfect the clearest liquid or finest powder still leaves behind its residue and though the victim may at first appear unmarked science can reveal how death was dispensed and dispense justice to the poisoner [Music] [Music] [Music] [Applause] [Music] you
