Man Tasered By Edmonton Police Dies

A man who was shocked by a Taser stun gun while in custody this week at Edmonton police headquarters has died.

Jeff Oatway, 34, had been in a coma on life support after he was taken to hospital on Wednesday.

Doctors declared him dead on Friday, said his father, Cliff.

The head of the Edmonton Police Association, Sgt. Tony Simioni, said Oatway "snapped" and became violent when officers were trying to get him ready for a bail hearing around 4 p.m. MT on Wednesday.

About a dozen officers were called to the scene as TV monitors were torn from the walls, computers were destroyed and desks overturned, Simioni said.

The Taser was used on Oatway after two officers were injured, Simioni said Thursday. He then suffered what police described as a "medical episode."

The Alberta Serious Incident Response Team has taken the lead in the investigation. ASIRT looks into incidents or complaints involving serious injury or death that may have resulted from the actions of a police officer.
