>> ALL RIGHT. WELCOME BACK. A YOUNG MAN WHO WENT MISSING IN HOUSTON 8 YEARS AGO AS A TEEN HAS BEEN FOUND. ALIVE. BUT ACCORDING TO HIS MOM, HE IS IN SOME BAD SHAPE. A GOOD SAMARITAN. SPOTTED 25 YEAR-OLD. RUDY FARIAS OUTSIDE A CHURCH ON SATURDAY. HE WAS UNCONSCIOUS, HAD DRIED BLOOD IN HIS HAIR AND WAS COVERED IN CUTS AND BRUISES. HIS MOM SAYS HER SON IS IN BAD SHAPE. BOTH MENTALLY AND PHYSICALLY. HE'S NOW RECOVERING AT THE HOSPITAL. FARIAS WAS REPORTED MISSING BACK IN 2015 AFTER HE TOOK HIS DOGS FOR A WALK AND NEVER CAME HOME IT WAS 17 YEARS OLD AT THE TIME. INVESTIGATORS SAID THEY DID NOT SUSPECT FOUL PLAY. ALL RIGHT. LET'S BREAK ALL THIS DOWN. JOINING ME NOW, A TRIAL ATTORNEY AND LEGAL ANALYST MISTING MARIS AND FORMER FBI AGENT KAPLAN. THANK YOU BOTH FOR BEING HERE AND KIND OF DIVING DEEPER INTO THIS WILD STORY. STEWART, I WANT TO START WITH GIVEN HIS FRAGILE STATE. HOW DO INVESTIGATORS EVEN GO ABOUT PIECING TOGETHER. WHAT HAPPENED TO HIM? >> WELL, THAT AND THAT'S A GREAT QUESTION. THE FIRST THING IS OBVIOUSLY HE'S GETTING THE PROPER MEDICAL ATTENTION AND THEY'RE GOING TO TRY TO INTERVIEW AND THEY'RE GOING TO SEE IF THEY CAN WORK BACKWARDS FROM YOU. ANY INFORMATION THAT HE MAY RECALL OBVIOUSLY THERE ARE SOME HEALTH ISSUES THAT WERE KNOWN TO THE FAMILY AND ALSO KNOWN TO LAW ENFORCEMENT BACK 8 YEARS AGO. AND SO THEY'RE GOING TO TRY AS BEST THEY CAN TO WORK BACKWARDS AND SEE WHERE THIS KID HAS BEEN FOR THE LAST 8 YEARS. IT'S JUST AMAZING TO MEET ASTONISHING TO ME THAT FOR 8 YEARS. NO OTHER THAN THIS GOOD SAMARITAN 8 YEARS LATER WAS ABLE TO IDENTIFY AND BRING THIS KID INTO, YOU KNOW, THE FALL. AND SO YOU HAVE TO WONDER WHERE HE'S BEEN THE LAST 8 YEARS WHO HE CAME INTO CONTACT AND WHETHER THERE WAS YOU KNOW, BY, YOU KNOW, SOME PEOPLE OR SOME PERSON THAT PREVENTED HIM FROM BEING FOUND AND DISCOVERED EARLIER. >> YEAH, 8 YEARS THIS I'M ASSUMING IS GOING TO BE A TOUGH 1 TO PIECE TOGETHER. MISTY, WHAT IF ANY LEGAL OPTIONS DOES THE FAMILY HAVE. >> WELL, FIRST OF ALL, IT IS ASTONISHING THAT HE'S BEEN FOUND. AND WHAT A MIRACLE AND MAKE SUCH AN EXCELLENT POINT ABOUT MENTAL STATE AND HIS ABILITY TO RECOUNT WHAT HE'S BEEN THROUGH FOR THE PAST 8 YEARS. LAW ENFORCEMENT PERSPECTIVE IN AN INVESTIGATORY PERSPECTIVE, WE IT'S BEEN REPORTED THAT HE HAS CUTS AND BRUISES. IF THERE'S SOME DNA AND FORENSIC EVIDENCE THAT COULD BE RETREAT THAT CAN RECOUNT THIS PATH OF THE PAST 8 YEARS. WILL CLOSE. IS HE WEARING IF THERE ARE SOME TYPE OF PHYSICAL EVIDENCE THAT COULD HELP IDENTIFY WHAT HAPPENED. NOW WITH BEGINNING OF THIS PLAY WAS NOT A WAS WAS NOT THOUGHT TO BE PART OF THE CASE. BUT NOW 8 YEARS LATER, GIVEN HIS CONDITION. IT SEEMS THAT CERTAINLY A FRESH INVESTIGATION MUST BE OPENED TO DETERMINE HOW HE'S BEEN A WAVE OF THIS LONG AND WHAT HE'S ENDURED DURING THAT TIME AND THERE COULD BE SOME PHYSICAL EVIDENCE ON HIS BODY
