Teen Who Stabbed Grandmother Found Dead In Lake Washington

SEATTLE, WA — A 16-year-old boy who police said stabbed his grandmother was found dead in Lake Washington on Monday afternoon. Police swarmed the Rainier View neighborhood around noon looking for the teen, only to call off the search when his body was found in the lake along Rainier Avenue.

At around noon, police responded to a home near 57th Avenue South and South Pilgrim Street on a report of a stabbing. The teen had apparently assaulted his 57-year-old grandmother with a machete before fleeing the scene on foot, Seattle police said.

Officers armed with shotguns and K9 dogs fanned out across the neighborhood, and King County Sheriff's Guardian One helicopter flew low over the neighborhood for more than an hour. At around 1:30 p.m., Seattle police said the suspect was dead.

Seattle firefighters responded to the 9860 Rainier Avenue South at around 12:30 p.m. for a water rescue. That address is along Lake Washington in an area lined with high-end waterfront homes. The teen was found under the water, but it wasn't immediately clear how he died.

The grandmother was taken to Harborview in stable condition, police said.
