RENTON — Authorities say a King County man has been arrested after his grandmother and a 21-year-old house sitter were found dead in separate killings.
Renton police Cmdr. David Leibman says a family returning from vacation found their house sitter dead just before midnight Tuesday.
Leibman says Zachary Craven was booked into King County Jail on investigation of two counts of homicide on Wednesday. Liebman says Craven is the former boyfriend of an adult daughter who lives in the home.
He says there were no signs of a struggle at the home, and a motive not immediately known.
Renton police say the man is also a suspect in a homicide in King County earlier in the day.
King County sheriff’s Sgt. Stan Seo says a woman was found dead in the Skyway area Tuesday and investigators believe her grandson is the suspect. Seo says there is a court order protecting the grandmother from her grandson.
