ARLINGTON, Wash. (AP) — An Arlington homeowner shot and killed a man he said knocked on his door at 4 a.m. and refused to leave. The Snohomish County Sheriff’s Office says the man and his wife were sleeping in their home when they heard knocking on their back door. The homeowner reportedly found a “suspicious man” knocking and refusing to leave. He reportedly told the man he had a gun but the man still wouldn’t leave. It’s unclear whether there was an altercation that followed, but the homeowner ended up shooting the man twice. The homeowner is cooperating with the investigation. Deputies don’t know whether he will be charged.
