A suspect has been arrested for selling Fentanyl that killed a Lyons man.

In early October 2023, a woman called 911 after finding a male family member unresponsive at their home in Lyons. Larimer County Sheriff’s Office deputies and investigators, Thompson Valley EMS, and Lyons Fire Department responded. They located the man, who was deceased, and evidence of illegal narcotic use at the scene. The Larimer County Coroner ruled his death accidental as a result of Fentanyl toxicity.

LCSO investigators began working to determine who supplied the lethal drug to the man. Through the course of their investigation, they identified Evans, Colorado resident Jason Wahlstrom (DOB 07/09/86) as the primary suspect. LCSO obtained an arrest warrant and requested the assistance of the Evans Police Department in apprehending Wahlstrom. EPD arrested the suspect in late February, and Wahlstrom was booked into the Weld County Jail on the following charges:

  • Unlawful Distribution of Fentanyl Resulting in Death (DF1)
  • Special Offender (DF1)

He was transferred to the Larimer County Jail in March and was issued a $100,000 cash/surety bond by the Larimer County Court. A booking photo is attached.

“The fight against Fentanyl is a serious issue that impacts our whole community,” said Investigations Captain Bobby Moll. “Our investigators will continue working hard to stop the destruction caused by this lethal drug."

LCSO would like to thank the Evans Police Department for their partnership and assistance in this case. The charges are merely an accusation, and the defendant is presumed innocent until, and unless, proven guilty.
