Wet road conditions on the Dallas North Tollway contributed to the death of a Glenn Heights woman on June 1.

Traffic investigators said that 30-year-old Keila Lee Wangen was traveling northbound on the toll road when her Land Rover lost traction and lost control.

Wangen’s vehicle skidded toward the right and struck the guardrail. It then rolled over down the embankment, ejecting Wangen.

Frisco Fire Department pronounced Wangen dead at the scene.

Further information on the accident is not available.
