LOS ANGELES — Investigators will likely seek Bruce Jenner’s cellphone records to determine if the Olympic gold medalist was texting when he was behind the wheel of an SUV involved in a four-vehicle highway crash in Malibu that killed a woman, authorities said Sunday.

The agency will likely collect phone records for all the drivers so investigators can check call and text data, said Los Angeles County Sheriff’s Sgt. Philip Brooks.

However, Brooks said it is difficult to determine if a driver was texting at the exact time of a collision. Investigators will look at signs of driver behavior such as multiple texts that span a period of time leading up to, or including, the crash, he said.

The sheriff’s department has custody of all the vehicles and will be inspecting them to ensure they’re mechanically sound or whether a defect prevented somebody from stopping in time.

Investigators are trying to determine who or what triggered the crash on the Pacific Coast Highway. One woman died, and seven others were injured.

Jenner was traveling north when his Cadillac Escalade rear-ended a Lexus sedan that had just struck the back of a Toyota Prius, Brooks said. The Lexus veered into oncoming traffic and collided head-on with a Hummer.

The driver of the Lexus – Kim Howe, 69, of Calabasas, California – was pronounced dead at the scene.

Jenner cooperated with investigators, passed a field sobriety test and voluntarily submitted a blood sample to determine whether he was intoxicated, Brooks said. Jenner wasn’t hurt.

Jenner won a gold medal in the men’s decathlon at the 1976 Summer Games, but he is known to a younger generation as Kim Kardashian’s stepfather.
