At least four people are dead in Key Peninsula, Washington, in a stabbing at a home early Tuesday morning, according to authorities. A call came in at 8:47 a.m. regarding a man violating a no-contact order at a home, according to the Pierce County Sheriff's Office. The order was not valid because deputies had yet to serve the man with a copy of the order, the sheriff's office added. Witnesses reported that a man "was stabbing people outside the home" as deputies were en route to serve the order at 9:30 a.m., according to the sheriff's office.

Boyd added that officials were working through the identification process for the deceased.…
