A Bozeman woman has been sentenced to 100 years in prison after being convicted of breaking into the house of a former tenant, ransacking the place and shooting the man in the head.
District Judge John Brown sentenced 59-year-old Diana Arnold on Wednesday for attempted deliberate homicide and aggravated burglary, saying he believed she intended to kill Henry "Dave" McDunn and his wife and burn their house down on May 30, 2012.
Arnold said she didn't remember much of what happened. Her attorney said she is mentally ill due to a brain injury suffered in a 1999 car crash and was in a "dissociative state" when she broke into the McDunns' house.
The attack happened shortly after a District Court judge ruled Arnold owed the McDunns $22,000 -- $1,500 for a security deposit plus attorney fees.
