A Los Angeles police official said that Bruce Jenner was being followed by paparazzi before the four-car collision that left one driver dead yesterday, but that did not appear to have caused the crash, the Los Angeles Times reports.

Paparazzi were in the area—some even managed to capture photos of the crash as it happened—but the Times characterized L.A. County sheriff's Sgt. Philip Brooks's attitude about this having caused the crash as "doubtful."

The crash involved four cars, not three as was initially reported. From the Times:

A woman driving northbound in a Toyota Prius slowed down or stopped for reasons that were unclear. A woman driving a Lexus sedan rear-ended the Prius.

Jenner, who was driving a black Cadillac Escalade sport utility vehicle that was hauling a trailer carrying an off-road vehicle, then rear-ended the Lexus.

The impact propelled the Lexus into oncoming traffic, where a Hummer traveling southbound slammed into the Lexus. The driver of the Lexus, whom authorities declined to identify, died at the scene.

"It was a nightmare," Brooks told the Times. He said that Jenner passed a field sobriety test, as TMZ had originally reported. TMZ also reports that Jenner volunteered to be taken to a hospital to have his blood drawn for a blood-alcohol test.

According to the Times, police will investigate Jenner's phone records to determine whether he was using his phone at the time of the crash.
