ABERDEEN, Wash. -- The Department of Corrections says it's still investigating the death of an inmate April 15th at the Stafford Creek Corrections Center near Aberdeen.
The 36-year-old Mullen had been sentenced to 44 years in prison last year for killing two registered sex offenders in Bellingham. Mullen found his victims on Whatcom County's online sex offender list. He posed as an F-B-I agent in August of 2005 to enter the home and shoot the men.The prison says Michael Mullen was found unresponsive in his cell and was declared dead at Grays Harbor Community Hospital.
Prison spokeswoman Sheri Izatt says Mullen was alone in his cell, and it's being investigated as an unnatural death, which includes the possibility of suicide.
