HAHA. >> JENNA BARNES: BRANDON WAS DIAGNOSED AN EARLY AGE WITH HEARING LOSS. SHE'S WORN HEARING AIDS AND SHE WAS 4 AND SHE DISCOVERED A PASSION FOR HELPING OTHERS WITH THE SAME DISABILITY. I KNEW THAT WAS EXACTLY WHAT I WANTED TO DO IS TO WORK AND THE IDEOLOGY FIELD. AFTER EARNING HER MASTER'S DEGREE FROM WASHINGTON UNIVERSITY IN ST. LOUIS BRAND MOVED TO LOS ANGELES TO START HER CAREER AS AN AUDIOLOGIST. HER HEARING SERVICE DOG ARIA BY HER SIDE. THE 2 SPENT MUCH OF THEIR FREE TIME AT A DOG PARK IN 1000 OAKS IN THE SPRING OF 2018. >> BEFORE WORK AFTER WORK. BUT I'LL BE THERE FOR HOURS TOO. LETTER HAVE FUN AND GET TO KNOW PEOPLE IN THE DOG PARK AREA. >> ONE OF THE PEOPLE BRITAIN GOT TO KNOW WAS CHAD, AMELIA A FEW WEEKS AFTER THEY MET CHAD WAS DEAD. BRAND CHARGED WITH HIS MURDER. >> I HAVE NO INTENTION TO HURT HIM. I NEVER WOULD HURT ANYBODY. >> JENNA BARNES: IT WAS MEMORIAL DAY WEEKEND AFTER A VISIT TO THE DOG PARK BRAN. AND CHAD WENT BACK TO HIS APARTMENT WHERE HE OFFERED HER MARIJUANA IN A BOMB. IT WAS LEGAL. BRAND WAS AN INEXPERIENCED USER. WHAT HAPPENED NEXT? SHATTERED TO FAMILIES WHEN BRAN UNEXPECTEDLY BECAME VIOLENT. >> THE MOST HORRIFIC THING TO US TO WATCH. BECAUSE THERE WAS NO. THERE WAS NO FIGHT OR OCEANS OR MOTORS FEELING SENSORY FEELINGS OF ANY KIND. THERE'S NOTHING. IT WAS JUST LIKE I WAS WATCHING A TV SCREEN OF JUST ALL THIS HOT, AWFUL THING HAPPENING. >> JENNA BARNES: WITH WHAT PROSECUTORS SAY WAS 3 KNIVES FROM THE KITCHEN. SHE STABBED CHAD, THUS ARE RATED EDGES OF THE KNIVES, LEAVING HIM WITH 108 WOUNDS. BRAND EVEN STABBED HER DOG. ARIA AND HERSELF ASSOCIATION OF REALITY. >> AND YOU DON'T HAVE NO SENSE OF TIME. YOU HAVE NO SENSE OF JUDGMENT. MORALITY, EMOTIONS. IT'S THE SCARIEST THING. >> JENNA BARNES: VENTURA COUNTY SHERIFF'S DEPUTIES RESPONDED THEIR BODY CAMERAS RECORDING THAT VIDEO EVIDENCE REMAINS UNDER SEAL. BUT BOTH BRANDS, DEFENSE TEAM AND THE VENTURA COUNTY PROSECUTOR HAVE WATCHED MANY TIMES. SHE CARDED HIS FACE. >> THE STABBING WAS HORRIFIC. ONE OF THE DEPUTY SHOOTS WITH A TASER GUN. >> 4 TIMES.

FOR THEM. >> JENNA BARNES: BRAND COVERED IN BLOOD WAS RUSHED TO THE HOSPITAL WHERE SHE UNDERWENT SURGERY AND SURVIVED HER. 43 STAB WOUNDS. HER MOM FLEW FROM CHICAGO TO TAKE CARE OF HER. >> SHE WAS GOING ASK CHAD S JED WHAT HAPPENED? I DON'T KNOW. IT WAS JUST A MATTER OF TRYING TO. JUST CONSCIOUSLY WAKING UP IS AND THAT OF TRYING TO EXPLAIN TO THE DETECTIVES WHAT I WAS EXPERIENCING, BUT SAYING IN A WAY LIKE, BUT I'D I KNOW I DIDN'T DO IT, BUT I SAW THIS HAPPENING. >> JENNA BARNES: BRAND SPENT 6 DAYS IN JAIL. PROSECUTORS INITIALLY CHARGED HER WITH MURDER, BUT OVER THE COURSE OF THE YEARS LONG INVESTIGATION JUST MONTHS BEFORE HER TRIAL, THEY REDUCED THE CHARGE TO INVOLUNTARY MANSLAUGHTER. THE REASON EXPERTS ON BOTH SIDES AGREED HER ACTIONS WERE THE RESULT OF A CANNABIS INDUCED PSYCHOSIS. THIS IS REALLY RARE. >> BUT IT CAN HAPPEN. IT'S KNOWN TO HAPPEN THERE'S BEEN HUMAN EXPERIMENTAL STUDIES THAT HAVE SHOWN THAT IF YOU GIVE PEOPLE HIGH LEVELS OF THC DIRECTLY TO ABOUT BLOOD STREAM, YOU CAN ELICIT PSYCHOTIC SYMPTOMS. >> JENNA BARNES: AT NORTHWESTERN UNIVERSITY'S FEINBERG SCHOOL OF MEDICINE, DOCTOR, SO SHOULDN'T PATEL STUDIES HOW CANNABIS AND ITS PRIMARY PSYCHOACTIVE COMPOUND THC AFFECTS THE BRAIN. HE SAYS THOSE MOST AT RISK OF EXPERIENCING CANNABIS DO PSYCHOSIS ARE PEOPLE WITH MENTAL ILLNESS OR PEOPLE WHO HAVE A FAMILY MEMBER WITH A PSYCHOTIC DISORDER OR IS IT POSSIBLE FOR SOMEONE TO BECOME VIOLENT WHEN THEY WOULD NORMALLY BE? >> IT'S POSSIBLE, DEPENDING ON THE DEGREE OF PSYCHO SAYS SOUTH ARE PROCEEDING THINGS IN THE ENVIRONMENT TO BE THREATENING, FOR EXAMPLE, THAT THEY ORDINARILY WOULDN'T OR WHEN THERE ACTUALLY IS NO THREAT. CERTAINLY ONE REACTION OF THAT COULD BE, FOR EXAMPLE, FEAR FOR WITHDRAWAL UNDER CERTAIN CIRCUMSTANCES. IT COULD BE HEIGHTENED AGGRESSION. >> LATE LAST YEAR, A JURY CONVICTED BRENT. >> WHEN YOU WERE WAITING FOR THAT SENTENCING, WHAT DID YOU THINK WAS GOING TO HAPPEN? >> I REALLY THOUGHT I WAS GOING TO PRISON. >> JENNA BARNES: BUT THAT'S NOT HOW THE JUDGE SIDE COURT TRANSCRIPTS, QUOTE, HIM SAYING NO ONE COULD HAVE FORESEEN THAT A SINGLE HIT OF MARIJUANA THAT NIGHT WOULD HAVE CAUSED SPACE SURE TO HAVE A TOTAL PSYCHOTIC BREAK FROM REALITY. CERTAINLY NOT CHAD. AND CERTAINLY NOT MISS PAY SURE. IN LIGHT OF THESE FACTS, I DO NOT BELIEVE THAT FURTHER INCARCERATION OF THIS PACER IS APPROPRIATE. >> GOOD BOY. >> JENNA BARNES: THE SENTENCE OR INSTEAD TO 2 YEARS PROBATION AND 100 HOURS COMMUNITY SERVICE SPECIFICALLY EDUCATING THE PUBLIC ON THE DANGERS OF THC THAT THIS JUDGE UNSOLVED. THIS DEFENDANT OF REALLY ANY RESPONSIBILITY OTHER THAN THE FACT THAT SHE'S CONVICTED SENDS A VERY DANGEROUS MESSAGE. CHAD'S FATHER CALLS THE SENTENCE A TRAVESTY OF THE SYSTEM WOULD SHIFT TO DO NOTHING. >> NOTHING AFTER TAKING ANOTHER HUMAN BEING'S LIFE. THAT'S NOT ACCOUNTABILITY. PROBATION GOING TALKING TO PEOPLE. I MEAN. >> THAT THAT'S THAT'S NOT JUSTICE. WHAT DO YOU WANT? THE AMELIA FAMILY TO HEAR FROM YOU NOW? I'M JUST. SO SORRY. I'M SO SORRY THAT THEY HAVE TO. WITH A HOLE IN THEIR LIFE AND WELL FOREVER. YOU KNOW, BE ABLE WAS CHAD, ANY AND THAT THEY HAVE TO GRIEVE. AND I JUST HOPE AND PRAY THAT THEY FIND SOME. COMPASSION AND FORGIVENESS. >> JENNA BARNES: BRITAIN'S REQUIREMENT TO RAISE AWARENESS ABOUT THE RISKS OF MARIJUANA COMES AMID THE DRUGS NORMALIZATION. THE FEDERAL GOVERNMENT IS MOVING TO RECLASSIFY IT AS A LESS DANGEROUS DRUG. ITS LEGAL RECREATIONALLY IN 24 STATES. AND MANUFACTURERS ARE CREATING MORE POTENT PRODUCTS THAT ARE MORE ACCESSIBLE THAN EVER. I SEE THIS NOT BEING GOOD. >> WE AS A POPULATION ARE BEING EXPOSED TO THINGS TODAY THAT WE JUST NEVER REALLY WERE EVEN A POSSIBILITY. 10, 15, 30 YEARS AGO. IT'S NOT SURPRISING THAT WE WOULD BE SEEING MORE PEOPLE HAVING SOME, YOU KNOW, INCREASED INCIDENTS OF SOME ADVERSE EFFECTS AND, YOU KNOW, CANNABIS INTO PSYCHOSIS, EXTREME OF THAT. IT'S STILL VERY RARE. BUT WE'RE SITTING HERE BECAUSE IT'S HAPPENING. I JUST HOPE THAT MY STORY WILL SAVE SOMEBODY ELSE'S LIFE. >> JENNA BARNES: BRAND IS APPEALING. HER CONVICTION FOR THAT FELONY AS SHE WORKS TO OBTAIN A LICENSE HERE IN ILLINOIS TO CONTINUE HER CAREER AS AN AUDIOLOGIST AS PART OF HER COMMUNITY SERVICE. SHE'S TEAMING UP WITH AN ADVOCACY GROUP CALLED EVERY BRAIN MATTERS THAT FIGHTS WHAT IT CALLS THE EXPANSION OF DRUG CULTURE. WE HAVE ADDITIONAL INTERVIEWS WITH THE FOLKS AT THAT ORGANIZATION ON OUR WEB SITE, WGN TV DOT COM. >> JUST LOOK FOR THIS STORY, GUYS. REALLY FASCINATING. THE NORTHWESTERN DOCTOR SAID THIS IS VERY RARE, BUT YOU DO KNOW OF DOCUMENTED CASES WHERE THIS HAS BEEN A PRECEDENT. YEAH, THIS DEFENSE IS CONSIDERED NOVEL. IT'S NEW, BUT THERE IS A CASE JUST FROM THE SPRING AND IRELAND AND FOUND NOT GUILTY OF MURDER BY REASON OF INSANITY BECAUSE OF MARIJUANA
