In 911 call, Colorado Springs man admits to killing woman


An arrest affidavit reveals what possibly led to the death of a Colorado Springs woman who was found with multiple gunshot wounds in a Walmart parking lot on April 4.

Joshua Thomsen, 21, has been arrested in connection to the death of 21-year-old Amy Shrieves.

According to the arrest documents, Thomsen called 911 admitting his involvement, telling dispatchers “I just killed someone.”

During the call, Thomsen said Shrieves texted him the night of April 3 and asked if he could kill her. Thomsen said the two met up around midnight and drove to Eleven Mile Reservoir.

He told police he asked Shrieves if she was sure, and “So about one o’clock, I shot her.”

Hours later, Park County sheriff’s deputies found evidence in a campsite near Park County Road 92, including “a red pool of unknown fluid, consistent as being blood, four shell casings, a red trail over snow with numerous strands of long dark hair” and more.

Thomsen was arrested in the parking lot of the Walmart on Eighth Street in Colorado Springs.  

He is being held in the Park County Jail on charges of first-degree murder, tampering with a deceased human body, and tampering with physical evidence.
