AUGUSTA — The man accused of killing 72-year-old Audrey Lou Benn on Friday confessed to police Tuesday night, according to an affidavit filed today in Kennebec County Superior Court.

Raymond Leslie Clark, 35, of Augusta, is charged with murdering Benn in her basement apartment on State Street in Augusta. He lived in an apartment one floor above hers. He told police he killed her because she “confronted him about being a sex offender and came at him with a knife,” the affidavit said.

Clark is scheduled to make his initial appearance in Kennebec County Superior Court at noon today.

According to an affidavit filed by state police Detective Jason Richards, Deputy Chief Medical Examiner Dr. Marguerite Dewitt found that Benn died of strangulation. Dewitt found bruises on Benn’s chin, right eye and on the right side of her mouth.

Richards’ report says Benn’s body was found across the head of her bed, with the tie of her green bathrobe around her neck

Clark was a target of the police investigation shortly after Benn’s body was found by her roommate who returned from work about 5 p.m. Friday.
