A former morgue worker already in prison for having sex with a woman's body has pleaded not guilty to two more charges of sexually abusing corpses.

Fifty-five-year-old Kenneth Douglas entered the plea Tuesday. He is being held on $50,000 bond at the county jail in Cincinnati until the latest charges are handled.

Douglas was an attendant at the Hamilton County morgue from 1976 to 1992. He is serving a three-year sentence imposed in the fall for violating probation and having sex with the body of a 19-year-old murder victim in 1982.

He was indicted last month on the new charges, which accuse him of assaulting two bodies in 1991.

His 1982 crime was discovered after he provided a DNA sample following a drug-trafficking conviction. The sample matched one taken from the murder victim.
