Sheriff's investigators plan to recommend prosecutors file a vehicular manslaughter charge against Caitlyn Jenner for a fatal car crash on the Pacific Coast Highway in Malibu last February.

Los Angeles County Sheriff's Department spokeswoman Nicole Nishida says investigators found the reality star was driving "unsafe for the prevailing road conditions" when Jenner's SUV rear-ended a Lexus, pushing it into oncoming traffic.

The Lexus driver, 69-year-old Kim Howe, was killed when her car was struck head-on by a Hummer.

Nishida says the case will be presented for final review next week. The district attorney will determine what charges Jenner ultimately faces.

A rep for the district attorney told FOX411 the office could not comment on Jenner's case at this time.

If convicted of such a charge, Jenner would face up to one year in county jail.
