The grandparents of a man accused of killing them were strangled at their Renton home after they held a party to welcome him home from prison, the King County Sheriff’s Office said.
The King County medical examiner’s office determined the cause of death for Robert R. Taylor, 82, and Norma J. Taylor, 80, was strangulation.
Their grandson, Michael Chadd Boysen, 26, was arrested Tuesday after a daylong standoff at a motel in Lincoln City, Ore.
He’s in serious condition and conscious at Legacy Emanuel Medical Center in Portland, sheriff’s spokeswoman Sgt. Cindi West said.
It could take a month to extradite him to Washington, West added.
