BIDDEFORD, Maine (NEWS CENTER) -- A man charged for a shooting in Biddeford that left two teenagers dead and a third person injured entered a plea of insanity Tuesday.
In December of 2012, Biddeford police were called when James Pak threatened his tenants. When the situation appeared to be diffused police left the scene. Moments later investigators say Pak carried out his threat and gunned down Derrick Thompson and his girlfriend Alivia Welch. Now, Pak's attorneys will attempt to show he was insane at the time of the shootings.
"It's difficult but I've had a defendant in the past that was found not guilty of murder based on insanity. So it's a viable issue in a lot of cases and I think this is a case where it is a viable issue", said Pak's attorney Joel Vincent.
The defense's case is likely to focus on James Pak's tough upbringing, being separated from his family as young child and becoming orphaned during the Korean War. One of his attorneys alluded to that briefly but wouldn't go into details.
"Mr. Pak is 75 years old. It will come out during trial the type of life he had, but I'll leave it at that", said attorney Larry Goodglass.
Investigators say it was a dispute over late rent and parking that led Pak to shoot and kill 19-year-old Derrick Thompson and his girlfriend 18-year-old Alivia Welch. Thompson mother was also shot. She pretended to be dead and later managed to call police.
According to the police affidavit filed after Pak's first court appearance, Pak spoke freely of shooting three people and telling them he was going to shoot them before firing the gun. His attorneys are now attempting to get those statements thrown out based on his mental state at the time.
