Possibly the most wholesome press conference I have ever seen. Magnificent work, Detective Cooper!

I wish that men like this representatives for our nation. Thank you for your service

Wow this mystery took a big left turn!

The detective is very well spoken

In 1963 I saw a woman in the grocery store open a bottle of pancake syrup, stick her finger in it and then in her mouth, cap the bottle and put it back on the shelf. She must have seen the look of horror on my face and gave me her own look of death. I tugged my mother on the sleeve and told her what had happened so she could give the bottle to the store for safety and she told me to forget about it. She was a nurse and I was shocked she left the bottle there. My whole life since then I've been the bottle and can opener. This is not good when your father is a pharmacist. He used to make up fluoride drops in the lab to keep our teeth strong. Anything gets opened in this house I'm the one who does it. But anyway I don't wish harm to anyone but it took only a few days for caps and lids to be protected. So it could have been done much sooner. That enraged me. Still does. Thank you for reading.

That was fascinating story and amazing work. Det. Cooper 👍🏼👍🏼👍🏼 and to the psychologist who explained the back story.

Well done Idaho Law Enforcement.  Idaho News does it well.  I sooo-ooo appreciate a channel that knows how to handle sound!!!!  Bravo!

amazing work! great presser too

I can't believe it . I grew up in Chicago and was 16 at the time. I  remember the murders like it was yesterday . My father was a Chicago Cop at the time so it was a topic everyday in our house and the city for months maybe more. On every news cast 4 times a day, front page of all the different news papers. And I can't believe it is finally solved in my life time. I wish my father was alive to see this. Thank you Detective Cooper for finally finding this mass murderer.

Wow. This will definitely become a Lifetime movie.
Kudos to the investigators! Well done.

This is why there are three different seals on pill bottles so that if you are in pain you can't get them open.

So he is the likely suspect for the Tylenol...

Crimes solved, or close to solved. This is really good news, wonderful work done on the part of the investigators.

Just wow! He literally said to another scientist it would be good to inject cyanide into medication, but that scientist didn't connect that to cyanide poisonings and report it to authorities. Scientists can be very dense I swear.

I was wondering how an update on a case could be a 50 minute video. Worthwhile to watch the whole thing.

Excellent detecting work!

Wouldn’t his fingerprints have been on file at WSMR in the military
So many alarms on this guy sad his victims died 😢

Great questions from the peanut gallery. Answered the one I had about the key.

So,  in 2026, we still have little communication between agencies (Boise to Chicago). It's a wonder that any crimes get solved. In 2023 Houston PD was caught shelving thiusands of cases using the excuse of not enough personnel available to work them. Crazy. Thank you, Idaho!!.

Congratulations to Detective Cooper. Wonderful work. Wondering what is up with Arlington Heights. Something to hide? You would think they would be celebrating and thanking Det.Cooper for his diligence.
