Two Whitehorse residents died Tuesday in a single-vehicle rollover on the Alaska Highway just north of Jake's Corner, the Teslin RCMP report.

Rhonda Rose Carlick, 31, and John Magoon, 43, were both found dead outside the vehicle at the scene of the accident, which was reported to the Teslin detachment at 5:26 p.m., says a press release issued this morning.

The Alaska Highway was closed for about 40 minutes, then opened to single-lane traffic. Two-lane traffic was restored at 10:07 p.m.

Teslin RCMP Cpl. Dustin Rusk said today evidence indicates the three-quarter ton pickup truck was travelling north toward Whitehorse when it crossed the centre line and rolled into the ditch on the southbound side of the highway.

Police suspect alcohol and speed were factors in the accident, he said.

Evidence indicates Carlick was driving at the time, and that neither she nor the passenger were wearing their seatbelts.

'If they had of been wearing their seatbelts, we would have likely been dealing with some injuries, but there's a high probability we would not be dealing with death.'

Rusk said the RCMP would like to hear from anyone who may have witnessed the accident or anything they think may be related.

Those who were on the scene when police arrived believe they were first on the scene but sometimes people see things they may not realize are related.

Driving conditions at the time were dry and normal.

Fire and ambulance personnel from Marsh Lake responded to the scene, with assistance from the Whitehorse ambulance crews.
