A Nova Scotia man accused of first-degree murder in the shooting death of his estranged wife four months ago in New Germany has been found unfit to stand trial.

Wayne Paul Eisnor, 47, of Barss Corner, appeared in Bridgewater provincial court Tuesday on the charge.

The court was told that Eisnor suffered a brain injury from a self-inflicted gunshot wound and does not comprehend that his wife, Christina (Tina) Mae Eisnor, 43, is dead.

Eisnor is accused of shooting his wife in the parking lot of Barry's Freshmart on June 30. He then turned the gun on himself.

Judge Anne Crawford ruled that Eisnor is unfit to stand trial because of mental impairment. He is being held at the East Coast Forensic Hospital in Dartmouth.

The Nova Scotia Criminal Code Review Board will determine within 45 days whether he is still unfit to stand trial.
