AUBURN  — A 21-year-old Maine man has pleaded not guilty to a murder charge in the death of a woman whose body was found buried in the basement of a Lewiston apartment building.

Bob Ryder of Lewiston entered the plea Thursday in Androscoggin County Superior Court.

Ryder was indicted by a grand jury earlier this month on a count of intentional or knowing murder.

The decomposing body of the victim, 38-year-old Danita Brown of New Gloucester, was found last month. She had been missing for several weeks.

Court documents say Ryder admitted he had hit Brown in the head with a clock and hid her body in the basement.

The Sun Journal says police learned of the case after Ryder allegedly told his Alcoholics Anonymous sponsor about the incident.
