SEATTLE — Michael Chadd Boysen, the 26-year-old felon accused of killing his grandparents hours after he was released from prison March 8, plotted the slayings from behind bars, according to two law-enforcement sources.
A day after Robert and Norma Taylor were strangled in their Renton-area home, detectives learned that Boysen had been talking about robbing and killing the couple while he was in the prison, the law-enforcement sources said.
Boysen told others at the prison that he was angry at his maternal grandparents and wanted them dead, said the two law-enforcement sources, who spoke on the condition of anonymity. He apparently wanted to steal cash and their car, the sources said.
