A man who killed his grandparents with a shoelace after they threw him a party to welcome him home from prison has entered a modified guilty plea to charges of aggravated first-degree murder.
Michael Chadd Boysen faces life in prison without the possibility of release when he's sentenced Oct. 18. He admitted in King County Superior Court Friday that a jury would likely convict him in the deaths of 82-year-old Robert R. Taylor and 80-year-old Norma J. Taylor at their Renton home on March 9.
Boysen was arrested three days later after a standoff at a Lincoln City, Ore., motel. He had taken cash and credit cards from the home.
Boyesen had been released from prison the day before the killings after serving time for attempted burglary. His grandparents picked him up at the Monroe Correctional Complex and held a party for him that night.
Prosecutors declined to seek the death penalty after consulting with the victims' family.
