A 17-year-old girl from Snohomish County was found deceased outside of a Bellevue house on April 18.

The Bellevue police and fire departments responded to the scene at 7:41 p.m. after receiving a report that there was an unconscious female outside of a house on the 600 block of 153rd Avenue Northeast, according to a news release.

When officers and firefighters arrived, they found the non-responsive female in the backyard. Bellevue fire personnel attempted lifesaving measures for several minutes before she was declared dead.

Bellevue police detectives and the King County Medical Examiner arrived to conduct an investigation into the circumstances of the death.

It was then they determined the victim’s identity, which has not yet been released.

At this point in the investigation, police are reporting her death does not appear to be from natural causes, though there were no obvious signs of trauma, they noted. The King County Medical Examiner will be doing an autopsy to determine a cause and manner of death.

All involved parties have been interviewed by Bellevue police detectives and there is no known risk to the neighborhood or the public at large, officers reported.
