Caitlyn Jenner's unsafe driving factored into a fatal accident in Malibu in February, according to an Los Angeles County Sheriff's report given to prosecutors on Thursday, and Jenner could faces manslaughter charges.
The Associated Press earlier reported that the sheriff's report recommended a manslaughter charge, but a source familiar with the case told NBC News no recommendation was made. If prosecutors make a decision to charge Jenner, she will be charged with misdemeanor manslaughter, at most, the source said.
Investigators found that Jenner was driving "unsafe for the prevailing road conditions" when her SUV rear-ended a Lexus, Los Angeles County Sheriff's Department spokeswoman Nicole Nishida told the Associated Press.

Jenner was hauling an off-road vehicle on a trailer behind her Cadillac Escalade on Feb. 7 when she steered to avoid cars slowing for a traffic light in front of her on the Pacific Coast Highway in Malibu.
Jenner's SUV rear-ended two cars, pushing the Lexus into oncoming traffic and also hitting a Prius. The Lexus driver, 69-year-old Kim Howe, was killed when her car was struck head-on by a Hummer.
The case will be presented to prosecutors for final review next week, Nishida said. The district attorney's office will determine what charges Jenner ultimately faces.
Jenner's attorney Blair Berk declined comment.
The fatal crash occurred months before Caitlyn Jenner's transition. She was formerly known as Bruce Jenner, the 1976 Olympic decathlon champion and Kim Kardashian's stepfather.
Howe's stepchildren have filed suit against Jenner claiming they've suffered enormous damages.
The lawsuit by Dana Redmond and William Howe does not specify how much they are seeking. They claim Jenner was negligent when she collided with their stepmother's car, causing them and other relatives "great losses."
Attorneys for Howe's step-children, Dana Redmond and William Howe, did not immediately return email messages seeking comment.
Another woman, Jessica Steindorff, who was driving the Prius, also filed suit seeking unspecified damages. A phone message for Steindorff's attorney, Brad Simon, was not immediately returned on Thursday.
Jenner's transition has played out in public over the past several months and included a high-profile interview with ABC's Diane Sawyer last April, in which Jenner, appearing nervous at first, declared, "Yes, for all intents and purposes, I am a woman."
Jenner last month received the Arthur Ashe Courage Award at the ESPY Awards for her bravery for publicly coming out as a transgender woman. She also appeared on the July cover of Vanity Fair — her transition complete — with a photo of a long-haired Jenner in a strapless corset, legs crossed, sitting on a stool.
Jenner also debuted a new Twitter account with: "I'm so happy after such a long struggle to be living my true self. Welcome to the world Caitlyn. Can't wait for you to get to know her/me."
An E! Entertainment network documentary series "I Am Cait," depicting Jenner's transition from a man to a woman, began airing on July 26.
Jenner has vowed to use her to celebrity platform to urge acceptance for others who are transgender.
