On Friday, five members of the Wolf-Millesi family filed a civil lawsuit against the reality TV star in the Los Angeles Superior Court for negligence, ET has learned.
According to the documents obtained by ET, the lawsuit claims that the family continues to deal with both "significant personal injuries and emotional distress" brought on by the incident. The lawsuit also claims that Jenner was "inattentive, failed to keep a proper lookout and drove at unsafe speed for road conditions."
The lawsuit gives detailed examples of the allegations of physical suffering by the people suing Jenner. According to the papers, Elga Maurer claims she suffered a severe cervical fracture that left her permanently disabled, while Peter Wolf-Millesi cites suffering severe nerve damage to his wrists and hands, causing him to be disabled from work. The court documents also state that the incident required Lea Wolf-Millesi to undergo emergency and ongoing orthopedic treatment, while she and Peter's then 1-month-old newborn, who was also in the vehicle, had to be transported to the UCLA Medical Center by ambulance for emergency treatment after not being responsive at the scene.
ET previously reported that Kimberly Howe, 69, was killed and seven others were injured as a result of the crash. Footage obtained by ET of the accident shows Jenner's Cadillac Escalade -- which was towing a trailer carrying an off-road vehicle -- hitting both a white Lexus, driven by Howe, and a black Prius. It also appears to show Howe colliding with a black Hummer.
In September, the 65-year-old Olympian told her side of the story to Today's Matt Lauer, claiming that despite reports that her speed could have been a factor in the crash, she was driving under the speed limit at the time.
"I was going 46 in a 50. My airbag didn't even go off," Jenner claimed. "All I needed was probably a half a second, you know, of time. I almost got stopped -- but I couldn't quite get it stopped. I was pulling a trailer so no, I don't think speed was [a factor,] anything like that."
