The family of a woman killed in a 2011 snowmobile accident is suing Manitoba Hydro and others for her death.

Mathilda Wollman, 48, was a passenger on a snowmobile when she was decapitated in February 2011.

The machine she was on was traveling on a trail in a ditch near Highway 12, just south of Steinbach.

According to the statement of claim filed on behalf of her family, the driver was trying to avoid traffic when he drove under a hydro guy wire, or support wire.

The snowmobile was a "two-upseat" model, which allows the passenger to sit higher than the driver and look ahead. As the pair  passed under the guy wire, the lower-sitting driver didn't have to duck but Wollman didn't see the wire coming.

Wollman's family is suing the driver, the two snowmobile groups that maintain the trail and Manitoba Hydro for not marking the wire properly.
