Defense attorneys say Berry Hall was not mentally stable during the 2008 shooting, but prosecutors argue that he acted in cold blood following a property dispute with Lisa and Alan Tackett.
"Don't sound like you were trying to kill them?" asked Floyd County Commonwealth's Attorney Brent Turner. "Don't sound like I was," replied Hall.
"Well to me it sounds like you were," said Turner.
"No actually I weren't," Hall replied defensively.
The defense called on two doctors to describe Hall's mental health.
The first said he had given Hall an IQ test which resulted in a score of 71.
"If you get very far below an 85, then it means you struggle with your thinking and reasoning ability. You're not as sharp as other people are," said Dr. James Walker.
Both doctors testified that Hall has very serious depression. They agree that Hall has what is called Major Depressive Disorder, but prosecutors ask, if that is their diagnosis, why didn't they put it in their reports?
Dr. Walker says that at the time the report was made, in 2010, he had not made an official diagnosis and needed more time with Hall to determine one.
But both doctors agree that Major Depressive Disorder coupled with a low IQ could drastically impact Hall's ability to think clearly, especially with stressors like his family's argument.
The defense will continue its case tomorrow.
