Police are investigating a double stabbing involving a 16-year-old girl who allegedly fatally stabbed her mother’s boyfriend and then stabbed herself in the abdomen on Friday morning, according to police.

The 35-year-old man who was stabbed multiple times was the live-in boyfriend of the girl’s mother, according to Federal Way Cmdr. Kurt Schwan.

Just after 8 a.m., South King Fire and Rescue crews and police responded to reports of a stabbing at the Greystone Meadows Apartments at 31500 1st Ave. S. in Federal Way.

Crews conducted CPR on the man, but were unable to revive him and he died at the scene, said SKFR public information officer Lt. Brad Chaney. The teen, who was found at the scene with a single stab wound to her abdomen, was transported by King County Medics to Harborview Medical Center with non-life-threatening injuries, Chaney said.

There are no outstanding suspects, and Schwan said it appears the girl stabbed her mother’s boyfriend and then stabbed herself, according to preliminary details of the ongoing investigation.

The mother was on scene at the time of the incident and detectives interviewed her Friday morning, Schwan said.

Apartment management notified residents of the stabbing in an email on Friday morning, confirming that a “domestic incident” occurred around 7 a.m. and police were on site investigating.

The Mirror will update this story as more information becomes available.
