RCMP in St. Albert said Wednesday morning that Const. David Wynn, an officer 'gravely' wounded in a shooting at a St. Albert casino Saturday morning has passed away in hospital.

The news came after Wynn's condition had not changed for several days.

Wynn is survived by his wife Shelly and three sons Matthew, Nathan and Alexander.

Wynn was shot in the head at close range early Saturday as he, and auxiliary officer Derek Bond investigated a stolen vehicle found in the casino's parking lot.

Bond was also wounded, shot in the arm and torso, but while he was released from hospital – RCMP said Wynn remained unconscious.

On Monday evening, Wynn’s wife, Shelly MacInnis-Wynn spoke publicly for the first time, thanking the RCMP and the public for their support in the wake of the tragedy.

However, MacInnis-Wynn said the family was saying their goodbyes.

Wynn, 42, worked with the RCMP D.A.R.E. program in St. Albert schools.

St. Albert Mayor Nolan Crouse also extended his deepest condolences to family, friends and colleagues. "We join you in mourning his passing as we struggle with the senselessness of his death."
