"My heartfelt and deepest sympathies go out to the family and loved ones, and to all of those who were involved or injured in this terrible accident," Jenner said via a statement to ABC News. "It is a devastating tragedy and I cannot pretend to imagine what this family is going through at this time. I am praying for them. I will continue to cooperate in every way possible."
A woman driving a Lexus rear-ended another car, and Jenner's SUV then hit the Lexus, pushing it into oncoming traffic, where it hit a Humvee, police said.
The driver of the Lexus was killed, while five people inside the Humvee suffered non-life threatening injuries, police said. Jenner was uninjured, said his rep.
Jenner cooperated with investigators, police said. He passed a field sobriety test and then voluntarily submitted a blood sample to determine whether he was intoxicated.
"He did not appear intoxicated or under the influence of anything at the time," said Los Angeles County Sheriff's Office Sgt. Philip Brooks.
Jenner's publicist says the Olympic gold medalist was not texting, and that Jenner will provide his cellphone records if requested.
Los Angeles County Sheriff's Office Sgt. Philip Brooks said that if investigators decide they want to see the cell phone activity, the information would be sought from all the drivers involved in the crash, and said Jenner was not considered a suspect in the crash.
"No, he's just a party to the crash," Brooks said.
"The problem is pinpointing the time of the accident," Brooks said, regarding whether phone records would be any help in determining the cause of the crash. "If the accident occurred at 12:05 and 30 seconds, or 12:05 and 40 seconds, if you hung up before that, that's useless information."
