The bodies of three apparent homicide victims were found Friday in a home west of Yakima when Yakima County sheriff's deputies checked on a report that one resident had not showed up for work.
The two women and one man are all believed to have lived in the home, sheriff's Chief of Detectives Stew Graham said.
Deputies found the bodies after the sheriff's office got a call Friday morning from a co-worker who was concerned that the man had not showed up for work Thursday, Graham said.
He refused to discuss how the three were killed. No names were released pending notification of relatives. County Coroner Jack Hawkins told the Yakima Herald-Republic he planned autopsies Monday.
No arrests have been made, Graham said Friday evening.
The home is located in the gated Falcon Ridge development about 10 miles from Yakima.
Graham described the development as rural, single-family homes "a little bit on the upscale side but not wildly."
The three are believed to have been killed between 5 p.m. Wednesday, the last time co-workers had contact with the man, and late Friday morning.
Washington State Patrol crime scene technicians were called to the home.
