One man was arrested after claiming responsibility for a house fire in Cosmopolis over the weekend. Police Chief Casey Stratton tells us that Officer Mitchell was the first to arrive at the two-story house in the 1500 block of 3rd Street just before midnight Saturday night. Mitchell confirmed that no one was inside the home, then began evacuating nearby residents. Cosmopolis and Aberdeen fire units responded and worked to contain the blaze as the entire top floor of the home burned into the early morning hours. Stratton said that around 6 a.m. Sunday morning an Aberdeen resident contacted police and took responsibility for the fire, he was arrested and transported to Grays Harbor County Jail where he faces arson charges.
