Duvall detectives determine suspicious deaths were murder-suicide

The deceased were discovered on July 6 after not showing up to a Fourth of July party.

The Duvall Police Department recently disclosed that a suspicious death incident, discovered on July 6, was a murder-suicide.

The deceased were discovered in a local residence by a third party who called 911. Police arrived on the scene at 8:38 a.m. and closed Northeast 152nd St. between 279th Lane Northeast and 279th Place Northeast, according to a press release. They found two people, a male and female, who were confirmed dead by fire department medical personnel.

“These types of incidents are tragic and senseless,” said Steven Sabourin, a DPD Lieutenant, in a press release. “Unfortunately no community is immune.”

Police assured locals that there is no general threat to anyone’s safety and that detectives are not searching for any additional suspects.

The third party was an acquaintance who went to check on the two after they didn’t show up to a Fourth of July party and hadn’t contacted anyone for a few days, according to a press release.

After determining that the death circumstances were suspicious, officers contacted Major Crimes Unit of the Coalition of Small Police Agencies (CSPA) and Washington State Patrol’s Crime Lab, who then began the investigation.

The investigation is ongoing, but Commander Larry Colagiovanni of the CSPA released preliminary investigation results on July 9 and determined that the incident was a murder-suicide.

DPD detectives are still working with the Washington State Patrol Crime Scene Unit and the Medical Examiner to determine all the facts of the case. Investigators will not release the names of the deceased pending positive identification, police said in a press release.
