Mullen pleads not guilty to sex offender killings

In Bellingham, the man charged with two counts of aggravated first-degree murder in the killings of two registered sex offenders has entered not guilty pleas in Whatcom County Superior Court.

Michael A. Mullen, 35, who had said at his initial hearing 10 days earlier that he wanted to plead guilty... has also changed his mind about legal representation, originally saying he wanted to represent himself. As of Friday morning, public defender Richard Fasey was officially working as Mullen's lawyer.
