BANGOR — A Bangor woman has been sent to a psychiatric facility after being found not criminally responsible by reason of insanity for the fatal stabbing of her boyfriend.

Gail Judd on Thursday entered her plea to the stabbing death of 47-year-old Michael Drouin in February 2012.

WABI-TV reports that a judge committed her to Riverview Psychiatric Hospital in Augusta indefinitely.

The 53-year-old Judd’s defense attorney said his client suffered from a liver condition that caused too much ammonia in her system, which sometimes drove her to a delirious state. He told the court she was in one such state when she stabbed Drouin.

Judd initially claimed self-defense in the stabbing, saying Drouin tried to rape her.
