BANGOR, Maine (NEWS CENTER)-- Thayne Ormsby pleaded not guilty by reason of insanity in his trial on charges he murdered 55 year old Jeffrey Ryan, Ryan's 10 year old son Jesse, and 30 year old Jason Dehahn in 2010 in Amity. Since Ormsby is using the insanity defense his trial will be held in two phases.
The first phase will determine if he committed the killings. If he is found guilty in that phase, the second phase of the trial will determine what his state of mind was at the time of the crime.
The insanity defense is explained in Title 17-A of the Maine Criminal Code.
It states: A defendant is not criminally responsible by reason of insanity if, at the time of the criminal conduct, as a result of mental disease or defect, the defendant lacked substantial capacity to appreciate the wrongfulness of the criminal conduct.
However, when attempting to show a defendant is not guilty by reason of insanity, the burden falls upon to defense attorney.
Jeff Silverstein, A Bangor Attorney who has defended clients with the insanity defense said that a lot depends upon the facts of the case, and the testimony of expert witnesses.
