A 12-year-old boy was killed in an accidental hanging at a home near Redmond.

Sgt. Cindi West of the King County Sheriff's Office told KIRO 7 Eyewitness News reporter Alison Grande the boy's mother left the house to look for him, and when she went out, she looked up and saw her son hanging.
Investigators are currently at the location processing the scene.
