Ada County Sheriff identifies man found dead in Boise church in 1982, possibly linked to the Tylenol cyanide poisonings in the 1980s.
The following is the YT transcription. It might be better just to watch all 10 minutes of the news cast.
Chapter 1: Identifying the wanderer
>> THE UNKNOWN WONDER WAS DETERMINED TO BE DOCTOR MATTHEW HOUSE KEY. >> TONIGHT, AN INFAMOUS IDAHO COLD CASES SOLVED. BUT COULD THE INVESTIGATION HELP UNRAVEL AN EVEN LARGER MYSTERY? THE MOST IMPORTANT? >> UNSOLVED CRIME IN MY LIFETIME. IF CHICAGO TYLENOL
MURDERS DR. BUT KOSKI MADE A COMMENT ABOUT HOW POISON COULD BE INTRODUCED INTO OVER THE COUNTER CAPSULES.
>> NO LONGER BE LINKED TO THE KILLINGS THAT ROCKED THE NATION IN THE 1980'S. >> IT'S NOT OUR JOB SUSPECT IN
SENSE. IT'S NOT IDAHO CASE. I BELIEVE HE'S AN EXTREMELY VIABLE SUSPECT. >> DESCRIBING A BRILLIANT BUT
LONELY MAN, A TALENTED CAN ASSIST STRUGGLING TO MANAGE SERIOUS MENTAL ILLNESS. SUBSTANCE ABUSE, HEAD INJURIES, GRIEF AND TREMENDOUS STRESS.
>> DEATH OF HIS MOTHER. WE'RE LOSING HIS JOB. A DIVORCE OF THE DEATH OF HIS FATHER. >> THE KEY TO THE CASE, A LITERAL KEY THAT SIGN EVIDENCE FOR DECADES. >> KEY THING HERE IS THE BREAK. IN THE CASE.
>> TONIGHT, EVERYTHING WE KNOW AND STILL DON'T KNOW ABOUT THE UNKNOWN WANDERER. THERE'S STILL A LOT OF QUESTIONS. WE DON'T HAVE ANSWERS TO.
>> KNECHT NEIGHBORHOODS ACROSS THE TREASURE AND MAGIC VALLEYS TELLING STORIES FROM WITHIN OUR COMMUNITIES. THIS IS IDAHO NEWS. 6. Chapter 2: Tylenol murder connection
>> THANK YOU FOR JOINING IDAHO NEWS. SENIOR REPORTER RILEY SHUMAKER. A BREAK IN AN IDAHO COLD CASE BRINGS CLOSURE FOR
SOME WHILE RAISING NEW QUESTIONS OR OTHERS. THIS AS VICTIMS, FAMILIES DEMAND ANSWERS. NEIGHBORHOOD REPORTER BRADY CASKEY KICKS OFF OUR
TEAM COVERAGE. >> TO COUNTY COLD CASE SOLVED ON YOUR VOICE. A NEIGHBORHOOD REPORTER BRADY KASKIN AFTER
MORE THAN 4 DECADES. WE NOW KNOW THE NAME OF THE MAN WHO KILLED HIMSELF IN A BOISE BENCH CHURCH IN 1982, I'M BREAKING DOWN HOW DETECTIVES IDENTIFIED THE UNKNOWN WANDER AND WHY EXPERTS ARE CONNECTING HIM TO THE HIGH-PROFILE TYLENOL MURDERS IN THE EARLY 1980'S. WELL, I BELIEVE THAT THE UNKNOWN WONDER IS EXACTLY THE KIND OF PERSON WHO WOULD HAVE COMMITTED THE TYLENOL
MURDERS. FORENSIC PSYCHIATRIST DOCTOR PARK DIETZ HAS BEEN INVOLVED IN MANY OF THE COUNTRY'S HIGHEST PROFILE CASES AND SAYS AS FAR AS HE'S CONCERNED, THE UNKNOWN WONDER WHO KILLED HIMSELF USING CYANIDE IS BEHIND THE CHICAGO MURDERS. THAT MAN IS NOW FORMALLY IDENTIFIED AS DOCTOR MATTHEW FRANCIS KOSKI WITH NO KNOWN TIES TO THE BOISE AREA. I'M CONVINCED ENOUGH THAT I THINK I CAN PUT IT TO BED FROM
COUNTY SHERIFF. MATT CLIFFORD SAYS HIS DETECTIVES CAME TO THE SAME CONCLUSION. THIS COULD VERY WELL BE A VIABLE SUSPECT FOR THE TYLENOL MURDERS. ADA COUNTY ISN'T IN
CHARGE OF THE TYLENOL MURDERS CASE SO THEY CAN SPECIFICALLY NAMED THAT KOSKI AS A SUSPECT. THEY PASS OFF WHAT THEY'VE LEARNED TO CHICAGO PD TO INVESTIGATE. BUT THIS WHOLE DEVELOPMENT CAME TO BE AFTER DETECTIVE TIM COOPER REOPENED THE COLD CASE BACK IN 2019, IT WAS MORE A QUESTION OF IDENTITY WE WERE INVESTIGATING A CRIME. WE'RE INVESTIGATING. >> A SUICIDE WHICH WAS AN UNFORTUNATE EVENT. >> WE'RE TRYING TO LEARN THE NAME OF THE MAN TO GET HIM BACK TO HIS FAMILY. LOOKING BACK THROUGH THE EVIDENCE, COOPER FOUND A SET OF KEYS THAT THEY USED TO TRACE THE UNKNOWN WANDER TO A FAMILY MEMBER IN FLORIDA USING DNA TECHNOLOGY THAT WASN'T AVAILABLE AT THE TIME. THEY WERE ABLE TO CONFIRM HIS IDENTITY WAS AN UNUSUAL FEELING TO BE ABLE TO PUT A NAME AND A FACE TO THE SKETCH THAT WE HAD HELD ONTO FOR SO LONG. BUT FOR EXPERTS LIKE DOCTOR DIETZ, THE CONNECTION BETWEEN THE CYANIDE, BUT KOSKI USED TO KILL HIMSELF, HAS TRAVELED TO CHICAGO, MENTAL HEALTH AND HIS INTEREST IN POISONS AND EXPLOSIVES MAKES IT ALL. BUT CONFIRMED. HE IS THE KILLER BEHIND THE TYLENOL MURDERS. YOU HAVE TO BELIEVE IN A LOT OF COINCIDENCES AND THINK THERE ARE MULTIPLE PEOPLE JUST LIKE HIM OUT THERE WHO ARE SLIDING DOWN HILL EXACTLY THE RIGHT TIME AND KILL THEMSELVES. IT EXACTLY THE RIGHT TIME.
>> TO BELIEVE IT WAS ANYBODY ELSE. >> A BRAND-NEW DOCUMENTARY FROM UNSOLVED MYSTERIES CALLED UNMASKING THE TYLENOL KILLER COMES OUT ON OCTOBER 9TH. THE ADA COUNTY SHERIFF HOPES THE DOCUMENTARY AND THE ANNOUNCEMENT OF THE UNKNOWN WONDERS IDENTITY WILL HELP TURN UP NEW LEADS IN THE CASE REPORTING IN BOISE ON BRADY CASKEY FOR IDAHO NEWS. 6. Chapter 3: The original cold case
>> SO WHAT EXACTLY WAS THE CASE OF THE UNKNOWN WANDERER SENIOR REPORTER ROLAND BERES BREAKS IT DOWN. >> IT WAS DECEMBER OF 1982.
WHEN A MAN KNOWN TODAY AS THE UNKNOWN WANDERER WAS FOUND DEAD NEXT TO A PEW IN SACRED HEART. CATHOLIC CHURCH. HE HAD
19 $100 BILLS IN HIS POCKET. IN A SUICIDE NOTE SIGNED WILLIAM TO ME NAME THAT WAS DETERMINED TO BE FAKE FACT THAT HE WAS WELL GROOMED. CLOSE WAS NICE AND NEEDY. LOOKED LIKE A VERY PROFESSIONAL PERSON. >> AND YET THERE'S JUST NOTHING. NOTHING FOUND ON TO YOU KNOW, IT JUST LEAVES A LOT OF SUSPICION. WHAT WAS GOING ON? WHY KILLED HIMSELF? THAT'S FORMER ADA COUNTY CORONER ERWIN SONNENBERG FROM AN INTERVIEW CHANNEL 6 DID WITH HIM DECADES LATER. WE ALSO INTERVIEWED THE BOISE POLICE DETECTIVE ON THE CASE, FRANK RICHARDSON. I WAS GOOD AT MY JOB. >> AND I PRIDED MYSELF BEEN
FACT THAT. I DON'T CARE WHAT IT WAS. I CAN SOLVE IT. >> I DIDN'T DO THAT.
>> DECADES LATER, WE FINALLY HAVE SOME THE FORMERLY UNKNOWN LAUNDERER DIED JUST MONTHS AFTER THE CHICAGO TELL NO MURDERS HE WAS CREMATED AND LAID TO REST IN EAGLE UNDER THIS STONE WITH THE FAKE NAME TO ME ON TOP. WE'RE LEARNING THAT WANDERER IS AN APT Chapter 4: Life of Dr. Betcowski
DESCRIPTION FOR BUT CAL SKI WHO SPENT MUCH OF HIS LIFE ON THE MOVE. >> AS AN ADULT DR GRIBKOWSKY LIVE IN 5 STATES. SOME OF THE MORE THAN ONCE YOU LIVE IN CALIFORNIA. YOU LIVE IN TEXAS, NEW MEXICO, OHIO, IN FLORIDA.
>> THE SHERIFF'S OFFICE SAYS THAT KOSKI SUSTAINED AT LEAST 2 MAJOR HEAD INJURIES, INCLUDING IN 1968 WHEN HE FELL HEAD. FIRST OFF THE RETAINING WALL ONTO CONCRETE. HERE'S LATER AFTER ANOTHER HIGH FALL ONTO CONCRETE. HE WAS INDUCED INTO A COMA. KOSKI LOST HIS MOTHER IN 1979. IN RECEIVED PSYCHIATRIC TREATMENT AT A STATE HOSPITAL IN FLORIDA 3 YEARS LATER, HE LOST HIS JOB AND A MONTH AFTER THAT, HIS FATHER LATER THAT SAME YEAR. BUT KOSKI WOULD DISAPPEAR FROM HIS NEW MEXICO HOME, SELL HIS CAR AND END HIS LIFE IN THAT Chapter 5: The Tylenol legacy

Please note:
” Official Stance: While the Ada County Sheriff’s Office has shared their findings with the Chicago Police Department, they have not formally named Beycowski as a suspect, as it is outside their jurisdiction...”
The Tylenol murders haven’t been solved but someone that fits all of the facts has been identified, the Idaho Wanderer.
CAPS LOCK OFf.
A summary:
After more than 40 years, Ada County investigators identified the “Unknown Wanderer,” a man who died by cyanide poisoning in a Boise church in December 1982, as **Dr. Mathew Francis Betkouski**. Detectives reopened the case in 2019 and ultimately used a set of keys and modern DNA technology to establish his identity. Betkouski had lived in several states, suffered major head injuries and personal losses, and had an apparent interest in poisons and explosives.
His identification has raised a new possibility in the **1982 Chicago Tylenol murders**, in which seven people died after taking cyanide-laced capsules. Investigators found potentially intriguing connections—including his knowledge of poisoning capsules, possession of cyanide, and a map of Chicago—but **there is currently no evidence placing him in Chicago during the murders**, and Ada County has not named him as a suspect. The information has been passed to Chicago investigators, while another unsolved cyanide poisoning from New Mexico in May 1982 is also being examined.
CAPS Lock - that’s from the YT transcription.
One reason why I mentioned that it may be easier just to watch the video.
Lot’s of cleanup from the YT transcriber.
Impossible to read.

This is a helpful site for converting case. Saves a lot of re-typing.
I just use the AI to summarize the video.
It’s a video, please lemme know it’s a video. I don’t like being coerced into watching a video. Thank you. That crime costs tax payers $billions of dollars in packaging changes.
Many thanks. Have not seen this site before.
Who Was Dr. Mathew Betkouski? Man Linked to Unsolved 1982 Tylenol Murders

It bears mention that the tylenol scare is why so many unlikely products are sold with “double-sealed” caps (tamper-resistant packaging).
