MISSOULA — A Missoula man who pleaded guilty but mentally ill to killing a Dixon man and seriously injuring the man’s wife has been sentenced to life in prison.
KECI-TV reports 32-year-old Nathan Lee William Calvert was sentenced Tuesday by District Judge Kim Christopher for the December 2012 death of Douglas Morigeau and the attack on Cheryl Morigeau.
Calvert pleaded guilty in September, saying he had been smoking synthetic marijuana for days and had been off his psychiatric medication for months when he broke into Morigeau’s house near Dixon. He told the judge he was paranoid that others were going to kill him.
An autopsy found Doug Morigeau was stabbed 54 times. Cheryl Morigeau’s throat was cut, but she was able to escape to a neighbor’s house to call for help.
