Gallatin County District Judge John Brown sentenced convicted Springhill shooter Diana Arnold to 100 years in prison.
In May of 2012, Arnold broke into Henry McDunn's home off Springhill Road.
Police say she waited there until McDunn arrived. And shot him two times, once in the back of the head and once in the chest.
McDunn survived, and wrestled Arnold to the ground while his wife called police.
Wednesday evening the five hour sentencing hearing was standing room only as more than 40 people packed a district courtroom. There were four people total who testified including Diana Arnold.
The first to testify was a son of Henry McDunn. He said Arnold did not deserve less than 80 years for shooting his father in May 2012.
When the case went to trial in July, the defense argued that Arnold suffered from traumatic brain injury from a car accident, has memory problems and occassionally sees things that are not there.
In court Wednesday afternoon, Arnold has one last chance to plead for leniency, she was the last person to take the stand. While she did apologize for the incident she said she cannot take responsibility for anything she does not remember.
After more than five hours and four testimonies both sides had one last chance to present their case. Defense Attorney Chuck Watson asked for Judge Brown to commit Arnold to the state psychiatric hospital in Warm Springs. While County Attorney Mary Lambert requested prison time.
Now that Diana Arnold will be behind bars for many years, Lambert says he hopes this will help bring closure to the family so they can begin to heal.
