The third victim of Friday's deadly plane crash northwest of Calgary has been identified, as the federal Transportation Safety Board continues to search for the cause of the crash.

James Dubarry, 42, was the Edmonton-based vice-president of an investment group. He leaves behind a wife and a son. 

Two other men travelling with Dubarry in the Cirrus SR22 were also killed when the single-engine, low-wing plane crashed in a farmer's field about 100 kilometres northwest of Calgary. They were Chuck Matson, 51, the former owner of the Calgary Hitmen junior hockey team, and Stephen Brosseau, 43.

Dubarry, who started flying at 17, was in the process of buying the plane from Matson, said Dubarry's brother-in-law, Nemer Fayad.

"In my heart, I wanted to tell him, 'James, don't buy it, please'," Fayad said. "But then last week, I said, 'You know what, that's awesome. I'm happy for you.' And you could just see the glow in his face — this little boy who saved all his pennies, and now, he gets to have his little toy.

"And the consolation is his life concluded with his passion."

Brosseau's death was announced Sunday by Alberta-based SMS Equipment, where he was the general manager of sales for mining equipment.

The company said Brosseau, of Spruce Grove, Alta., was in the process of getting his pilot's licence and a light aircraft. 

Const. Earl Hutchinson of the Sundre RCMP said investigators are still sifting through the wreckage of the plane.

"The [Transportation] Safety Board of Canada is presently conducting an investigation into the flight path of the aircraft, as well as the possible cause of the crash. That has yet to be determined," he said.
