Dirt bike passenger who died in chaotic Bay Bridge crash ID'd

OAKLAND, Calif. - A 20-year-old passenger on a dirt bike died Sunday night after a collision involving multiple vehicles amid a wave of motorbikes and all-terrain vehicles driving the wrong direction on the Bay Bridge in California.

The passenger has been identified by the San Francisco medical examiner as 20-year-old Christopher Lee.

According to the California Highway Patrol, Lee, a resident of Beaumont, Texas, died after a dirt bike he was a passenger on crashed into a median wall. The impact caused Lee to be thrown onto the roadway, where a pickup truck struck and killed him.

Multiple videos posted online and shared by news outlets, including KTVU, showed dozens of motorcycles, dirt bikes and ATVs cutting through traffic on the bridge that runs between San Francisco and Oakland about 5:30 p.m. 

CHP officers initially responded just after 5 p.m. for a report of a sideshow involving as many as 15 dirt bikes heading toward the Bay Bridge. When CHP patrol cars encountered the bikes on the bridge's eastbound lanes, the riders allegedly turned around and began heading in the wrong direction.

The riders then exited at the Sterling Street and Fourth Street off-ramps, traversed downtown San Francisco and re-entered the bridge the wrong way on the Fremont Street on-ramp, heading east on the upper deck of the westbound Bay Bridge, according to the CHP.

Lee, who was part of the group of dirt bike riders, then crashed his bike near the Treasure Island ramp. Another dirt bike rider, however, picked up Lee as a passenger, CHP officials said.

As officers pursued the pair, the bike's driver attempted to evade officers by trying to jump the median wall, causing Lee to be ejected onto the Bay Bridge, where he was hit and killed.

The crash resulted in two lanes of eastbound Interstate Highway 80 east of the Treasure Island tunnel to be shut down for hours Sunday evening, causing major delays.

The dirt bike's driver, who was injured in the crash, has since been arrested, CHP officials said.
   
It's unclear why the bikers were creating havoc on the bridge and if they were affilated with any particular group. At least one person was arrested.
