A man accused of killing his wife suffered retrograde amnesia and does not remember the day of her death, a Bridgewater, N.S., court heard Friday.

Wayne Paul Eisnor is accused of shooting and killing his estranged wife, Tina Mae Eisnor, in a grocery store parking lot in New Germany in June 2010. Eisnor was also shot, and claims to have no memory of the incident.

Jeannette McGlone specializes in treating people with brain injuries and brain diseases. At the request of his defence team, the neuropsychologist studied CT scans showing damage from a self-inflicted bullet wound to Eisnor's head.

"He had profound retrograde amnesia that spanned six months from January 2010 to June 2010," she said.

She told the court she doesn’t believe he’s faking the condition.

'Black hole'

The court also heard from Eileen Brunet, a forensic psychiatrist. She first saw Eisnor two months after the shooting. She examined him multiple times over the next couple of years.

She said he has no recollection of the time of his wife’s death and she described his memory as having a "black hole."

She said the memory gap extended backwards from the day of the killing in June 2010 to Jan 1, 2010.

The trial continues.
