***UNIDENTIFIED MALE of Wheat Ridge, CO***

On December 27, 2024, the skeletal remains of an unidentified individual were found by a gold panner in the Arapahoe Bar Gold Panning Park of Wheat Ridge.

Despite an extensive investigation and community outreach, the remains have yet to be identified. We believe they belonged to a White male who stood 5'4'' to 6'2'' and was 50 to 70 years of age and estimated to have died between 2021 and 2023.

Our office has teamed up with forensic company Othram to identify the remains using DNA evidence. For the full story and to contribute to the cause, click the link in the comments below.

We appreciate any and all help.

What do chocolate chip cookies and fentanyl have to do with each other??

It's called the chocolate chip cookie effect . . .

It's a term often used in pharmacology and toxicology to explain the uneven distribution of a potent substance with a larger mixture. Just like chocolate chips are unevenly distributed in a cookie, street fentanyl is unevenly distributed through each batch of drugs. As a result, every time someone uses drugs that may contain fentanyl, they are tempting fate because there's no way of telling if they will be ingesting a lethal dose of fentanyl.

Test strips will show the presence of fentanyl but not the amount or lethality.

The safest course of action is simply not to use drugs or illicit substances. If you take medications, only take them if they've been prescribed by your doctor. Don't take someone else's loose pills because you don't know where they came from and what's in them.

Stay safe!
