Sheriff’s Department detective Richard Curry said Jenner was driving at an unsafe speed on February 7 when her Cadillac Escalade rear-ended Kim Howe’s Lexus, sending it into oncoming traffic and leading to the 69-year-old driver’s death.
It could result in Jenner being charged with misdemeanor vehicular manslaughter for which the maximum sentence is one year in county jail.
Her attorney, Blair Berk, declined to comment.
The senior citizen died at the scene.
An official report on the incident concluded Caitlyn was driving too fast for road conditions, despite being under the speed limit, and she violated Penal Code section 192(c), which corresponds to misdemeanour vehicular manslaughter law.
