LOS ANGELES — Caitlyn Jenner could face a vehicular manslaughter charge after sheriff’s investigators found she was driving unsafely when she caused a chain-reaction crash that killed a woman in February, officials said Thursday.

Investigators determined Jenner was driving at a speed “unsafe for the prevailing road conditions,” Los Angeles County Sheriff’s Department spokesman Nicole Nishida said.

Jenner was hauling an off-road vehicle behind her Cadillac Escalade on Feb. 7 when she steered to avoid cars slowing for a traffic light on the Pacific Coast Highway in Malibu.

Jenner rear-ended two cars, pushing a Lexus into oncoming traffic and also hitting a Toyota Prius. The Lexus driver, 69-year-old Kim Howe, was killed when her car was struck head-on by a Hummer.
