A man has been charged with two counts of aggravated murder in the first degree in the deaths of two men found beaten to death in a Spanaway home on Sunday.

The Pierce County Prosecutor charged Richard Atkisson, 40, in the deaths of Joseph Moisa, 66, and Michael Henderson, 20.

A deputy verifying the address of a sex offender at the home discovered the bodies. Atkisson was arrested a short time later.

According to court documents, Atkisson told detectives he had been living with Moisa, a registered sex offender, and Henderson for about a year.

"The defendant told the detectives saw (sic) Mr. Moisa developing sexual relationships with young men, and he could not handle it," the documents say.

Documents say Atkisson told detectives he decided to kill both men and he thought about it and planned it for about a day.

The documents say Atkisson told detectives he used a pipe to beat one roommate and later placed a bag over his head until he stopped breathing because he "was just not dying." He used the same pipe to kill the other roommate, documents say.

The Prosecutor's Office cited the following aggravating factors: there was more than one victim and the murders were part of a common scheme or plan.

Atkisson had a felony warrant out of California. He was required to register as a sex offender there but failed to do so. He has prior convictions for burglary, rape, sodomy, and robbery.
