Man charged with 2 counts of aggravated murder in slaying of grandparents

Updated:

SEATTLE - Michael Chadd Boysen, the 26-year-old man accused of killing his grandparents in Renton, has been charged with two counts of aggravated first-degree murder.

 Boysen was captured by Oregon authorities last week in Lincoln City, where he was found hiding in a motel room.

 Boysen was released from prison in Monroe on March 8 and was picked up by his grandparents, Norma and Robert Taylor, who brought him to their home, where they had a dinner with other family members to celebrate Boysen’s release, police said.

 The other family members left after the dinner, but Boysen planned to spend the night, court documents said.

 Charging documents said the next day, Boysen’s mother found the bodies of Boysen’s grandparents piled in a guest bedroom closet in their home, and their red Chrysler 300 was missing.  The couple had been strangled, the King County Medical Examiner’s Office said.

 Documents said cash and credit cards were missing from the home, and a cellphone, iPad, laptop, suitcase and other items had been purchased the same day the couple’s bodies were discovered.

 Boysen’s mother said it was common for her mother to save and hide cash in her home over the years.

 Records showed that Boysen had stayed at a Tukwila hotel that night, where he listed his vehicle as a Chryusler 300 and used his grandparents’ phone number during the registration, court papers said.

 After Boysen was taken into custody in Lincoln City, Ore., investigators searching Boysen’s motel room said they found Robert Taylor’s credit cards, several thousand dollars in cash and an iPad.

 Police said the Taylors’ Chrysler 300 was found in Salem, Ore., where Boysen purchased a Ford Taurus with cash.

 Investigators found Robert Taylor’s wallet, as well as  jewelry, a Winchester rifle, several cans of kerosene, propane bottles and other items, prosecutors said.

 Detectives said that during interviews with inmates at the Monroe Correctional Complex, they were told that Boysen had talked about being angry at and wanting to kill his grandparents, take their cash and steal their car.

 Aggravated murder carries two possible punishments, either the death penalty or life in prison without release.

 Boysen is being held without bail in the King County Jail.
