A first-degree murder case is moving forward against a man accused of fatally shooting his estranged wife before attempting suicide in a grocery store parking lot.

A Nova Scotia Supreme Court judge has upheld a ruling that Wayne Paul Eisnor is fit to stand trial in the death of Tina Eisnor.

The ruling clears the way for a two-day preliminary hearing at the end of the month.

Eisnor is accused of shooting the woman twice as she sat in her vehicle in a parking lot in New Germany, about 25 kilometres northwest of Bridgewater, on June 30, 2010.

He then turned the gun on himself, causing a brain injury that has raised questions about his mental fitness.
