BELFAST  —  Dennis Edgecomb has pleaded not guilty to a charge he strangled his girlfriend to death last month at their Morrill home.

The Bangor Daily News says 39-year-old Edgecomb entered the plea Tuesday in court in Belfast. He called police on July 20 to say he’d killed 42-year-old Pamela Green.

Green’s daughter told investigators her mother sent a computer message about an hour before Edgecomb called police in which she said he was threatening to kill her.

At the time Edgecomb told investigators Green attacked him because he was planning to move out.

Edgecomb allegedly told police he pushed Green down onto a couch and choked her until she stopped moving.
