PORTLAND — Testifying at his murder trial this morning, William Hanaman said he woke up in his truck at a grocery store parking lot on Nov.10, 2009, with his hands shaking and his clothes covered in blood.

“I sat there for a while,” he said. “I knew something terrible had happened.”

Hanaman told the jury that the last thing he remembered, before waking up in the truck, was a frightening confrontation with his girlfriend, Marion Shea.

“I seen flashes. I seen the anger in her face. I remember something shiny in her hand,” he testified.

Hanaman is expected to continue his testimony after a lunch break at Cumberland County Superior Court.

He is charged with murdering Shea at his Ocean Avenue apartment. Hanaman, 52, claims he stabbed her in self-defense. The trial opened Tuesday.
