BOZEMAN - A Bozeman woman was found guilty of attempted deliberate homicide and aggravated burglary for breaking into her former tenants' home and shooting one of them.
Diana Arnold, 59, showed little emotion as the verdict was read, issuing just a small gasp when she was declared guilty of attempted deliberate homicide. Some of her family members, who were present during the one and a half week trial, wiped away tears.
Jurors deliberated for about 15 hours before reaching their verdict.
Arnold's attorney Chuck Watson claims Arnold suffers from a head injury she sustained in 1999. He believes this is a case of mental illness. He said he plans to appeal.
Arnold and the victim, Henry "Dave" McDunn both took the stand during the trial, telling different stories of what happened inside the McDunns mobile home on Springhill Road on May 30, 2012. McDunn said he came home that day, walked inside his home, bent down to put a leash on his dog and that's when he was shot. Arnold claims she doesn't remember the events of that day but said at one point she tried to leave, but McDunn wouldn't let her and continued to beat her.
McDunn suffered gunshot wounds to his head and chest. Arnold's face was bloodied and bite marks covered her shoulder and back.
The assault ended when Dave's wife, Kathy McDunn came home and called 911.
Arnold is being held in the Gallatin County Detention Center on $1 million bail. Her sentencing is set for two days, Oct. 7 and 8.
