UPDATE: Crash on Beaumont Freeway Kills One, Circumstances Revealed

UPDATED at 9:25 p.m.

The driver of a motorcycle died after losing control of his bike and getting run over by a big rig.

The crash occurred just before 6 p.m. on the westbound I-10 approximately 1/4 mile east of Beaumont Avenue, according to Jody Hagemann, spokeswoman for Cal Fire.

The motorcycle rider has been identified as 29-year-old Christian Lancaster, of Cathedral City. Lancaster was riding a 2003 Honda CBR-600RR, according to CHP Officer Darren Meyer.

"He was the last rider in a small sport bike motorcycle group," said Meyer. "As Lancaster was attempting to keep up with the group, he came upon a Chevrolet Suburban towing a flatbed trailer in the slow lane and a big-rig truck towing a semi-trailer in the #3 lane. He attempted to split the lanes, riding between the Suburban on the right and the big-rig on the left. As he was passing between the vehicles he lost control of his motorcycle. Lancaster was thrown from the motorcycle and landed in the number 3 lane, directly in the path of the big-rig’s right rear trailer tires. He was run over by the big-rig and pronounced deceased at the scene."

The big rig did not stop and is described as being red and pulling a light colored semi-trailer.

Alcohol and drugs were not determined to be a factor.

While CHP investigated the scene, the two right lanes of Westbound I-10 were closed for around two hours.

Anyone with information is being asked to contact CHP officer Steven Storm at 951-769-2000.
