A woman was killed Wednesday night when she crashed her vehicle into a tree just off state Highway 24 near Lafayette, according to the California Highway Patrol.
At 6:56 p.m., the CHP received a call about a solo vehicle crash on westbound Highway 24 near Pleasant Hill Road. A Tesla Model S was traveling west when it left the roadway and struck a tree.
The driver was transported to a hospital, where she died.
Investigators said they believe the driver suffered a life-threatening medical emergency, which caused her to lose control of the vehicle and hit the tree.
