Girl, 12, dead after Alberta ATV accident

A 12-year-old girl is dead after an ATV accident west of Edmonton.

The vehicle flipped and then pinned the girl, who was driving, in a gravel pit about 20 kilometres east of the village of Cadomin on Saturday afternoon.

The girl was wearing a helmet but died from her injuries.

“We are all deeply saddened by this tragic event,” said Const. Nathalie Bandet with Hinton RCMP.

Bandet says the girl was not supervised at the time of the accident.

In Alberta, children under the age of 14 must be accompanied by an adult, either on the ATV or in a nearby vehicle.

However, police say no charges are likely.

Bandet says ATV accidents are common in the area, but the fact that the girl is so young makes this incident especially difficult.

“I don’t remember an accident happening at this age. We have had death in the community involving quads, mostly on the May long weekend."

Cadomin is about a four-hour drive west of Edmonton.
