Nevada Highway Patrol troopers are investigating a rollover near Tonopah that killed a Las Vegas woman.
Troopers say the accident happened on Saturday just after 9am on US6 east of mile marker 48 in Tonopah.
They say a preliminary investigation indicates a 1999 Nissan Quest was heading west on US6 when for some unknown reason it crossed into oncoming traffic onto the south dirt shoulder, hit a paddle marker and traveled more than 550 feet before striking a culvert and overturning.
The driver, 76-year-old John Lehan of Las Vegas, was thrown from the Nissan and suffered injuries to his upper body and was transported to Nye County Hospital. The passenger, 71-year-old Sharon Lehan of Las Vegas, died at the scene.
Troopers say both people were wearing their seatbelts and it's currently unknown if alcohol was involved.
