A Robbinsdale man has been charged in connection with the death of a man who overdosed on heroin, according to charges filed in Anoka County District Court.

Tyler Koski was charged with third-degree murder in the death of John Wyatt Koscielski, 21, in October after Koscielski was found unresponsive in a Fridley residence with heroin and drug paraphernalia near him. He died of heroin toxicity on Oct. 22, according to a criminal complaint.

Koscielski met up with Koski at a pizza place about 6 p.m. on Oct. 21. Both were addicted to opioids, the complaint said.

Koscielski was with a co-worker when he met up with Koski. After the meeting, Koscielski and the co-worker went to a nearby gas station. Koscielski used the bathroom and was noticeably “under the influence” when he came out, the complaint continued. Koscielski was taken to his home in Fridley, where he was last seen alive at 1 a.m. Oct. 22.

Phone records show Koski and Koscielski traded calls in the days leading up to the meeting. Koski sent a text message to Koscielski while he was in the gas station that read, “Remember you don’t have a tolerance like you used to. I say do a small shotgun st.”

Koscielski was found dead the next morning. Koski later admitted to selling heroin to Koscielski at the restaurant.

If convicted, Koski could face up to 25 years in prison and a $40,000 fine.
