SUQUAMISH, Wash. (AP) — The children of a Native American man killed by police in Washington state two years ago are suing, saying his death was unnecessary. Stonechild Chiefstick, a member of Montana’s Chippewa Cree tribe who had close ties to the Suquamish Tribe in Washington, was shot and killed while attending an Independence Day celebration in the city of Poulsbo in 2019. He was reportedly menacing people with a screwdriver. But according to a federal lawsuit filed against Poulsbo on Thursday, he had dropped the screwdriver and was unarmed when an officer shot him. The lawsuit alleges excessive force and inadequate training. The city declined to comment.
