RENTON, Wash. — Post-mortem examinations by the King County Medical Examiner's Office did not determine any "obvious manner of death" for the father and his two daughters found dead in a Renton apartment on Saturday.
Further laboratory and scientific testing will have to be done, according to the Renton Police Department. That process can take weeks.
Renton police were called by a relative who said she hadn't heard from the three for some time. Police checked the apartment Friday but found nothing.
The investigation began after a landlord entered the apartment in the 300 block of Factory Avenue North and found the two girls, ages 16 and 17, dead in the living room. Their father, who is in his 30s, was found dead upstairs.
Renton Detective Robert Onishi said, "We don't see situations like this, generally. Definitely not with multiple victims."
The apartment, according to police, was in "really good condition." There were no obvious signs of foul play, no visible trauma to the bodies and no signs of a struggle.
"It was unusually neat and tidy," Onishi said. "There was very little furniture in there."
The Renton Police Department is asking people with information to call 425-430-7500 and reference case number 21-12197.
