A Lonedell woman was killed in a car crash Tuesday, Nov. 7, in Jefferson County.

At 8:33 a.m., Steven A. Jeffries, 28, Pacific, was driving eastbound on Route F when his vehicle started to slide as he rounded a curve. He steered right to avoid impact with another vehicle.

He then drove off the south side of the road, overturned and struck several trees, according to a Missouri State Highway Patrol preliminary report.

Passenger Sirisa T. Nelson, 26, Lonedell, was taken to Schaefer Mortuary Service by the St. Louis County Medical Examiner office, according the patrol.

Neither the driver nor passenger were wearing seat belts, the patrol said.
