A man charged with his wife's death took the stand Friday in Bridgewater in the final day of court proceedings challenging the decision that he is fit for trial.

Wayne Paul Eisnor is accused of shooting his wife Tina Mae Eisnor in June 2010 outside a New Germany grocery store.

Eisnor was found on the ground with a .22-calibre rifle under his body and suffered significant brain damage from a self-inflicted gunshot.

Tina Eisnor died a few hours later in hospital.

The defence is challenging a ruling that has already deemed Eisnor fit to go to trial.

Initially, he was found not fit to stand trial. Last July, Nova Scotia Criminal Code Review Board found his cognitive abilities had improved enough to participate in a trial.

Eisnor's memory

The Crown asked Eisnor Friday if he remembered the incident and his subsequent time in hospital.

"Faintly," he replied. "I remember being tied down by handcuffs. There were two policemen there. They were nice. They talked to me. I had brain damage. I remember reading about it in the paper."

The family said hearing Eisnor's testimony was hard. Tina Eisnor's siblings said they are suspicious of what they heard.

"He knows what he done, I always use the phrase as 'smart as a fox' because he was always like that," said Jody Illingworth, the victim's brother. "It's difficult to watch him up there. To me, he's faking it."

"It's hard to grasp everything because logically, someone with a gunshot wound, it's obviously going to have an effect on his memory," said Devan Illingworth, Eisnor's son.

Devan Illingworth said he's conflicted with emotions when it comes to his father, with whom he no longer has contact.

During cross-examination, Crown attorney Alonzo Wright had Eisnor to go into detail about his collection of five guns — including the handgun police believe he used June 30, 2010.

"I had a short gun, a .22 that I bought from a school teacher. I kept it in the kitchen cupboard," he said.

Eisnor was on the stand for about two and a half hours.

Defence lawyer Roger Burrill said he hopes the judge hearing the case will rule his client is not fit for trial.

"We have a man who shot himself and he caused himself extreme brain damage.  So you tell me when it comes to an issue with your brain, it's extremely complex," Burrill said.

Chief Judge Gregory Lenehan will give his decision on April 3.
