Medical Examiner: Renton grandparents strangled to deathon March 14, 2013 @ 10:39 am (Updated: 11:01 am - 3/14/13 )
Robert Taylor, 82, and his 80-year-old wife Norma were found dead inside their home Saturday afternoon.
Their 26-year-old grandson Michael Chadd Boysen is suspected in the murders.
Police say he had only been out of prison a few hours when he killed the couple and fled to Oregon.
His grandparents had picked him up from the Washington state prison at Monroe. They drove him to a meeting with a parole officer Friday, helped him get an identity card from the Department of Licensing and held a party for him.
Their bodies were found by Boysen's mother when she went to check on her parents.
Boysen was arrested on the Oregon Coast Tuesday after a 10-hour standoff with police.
A co-manager at WestShore OceanFront Suites in Lincoln City, Ore. recognized Boysen as a man who'd checked in at the motel on Monday.
They called police, which prompted a daylong standoff that ended with officers storming Boysen's room and finding him lying on the floor with self-inflicted cuts.
Boysen remains at Legacy Emanuel Medical Center in Portland, Ore., in serious condition.
Boysen is being held without bail. Investigators don't know why he went to Lincoln City or why he killed his grandparents, said King County sheriff's Sgt. Cindi West.
Boysen had just finished serving nine months in prison on a burglary conviction, said Washington state Corrections Department spokesman Chad Lewis. He was previously in prison between 2006 and February 2011 for four robbery convictions. Those convictions were related to an addiction to narcotic painkillers, Lewis said.
