Witnesses tell the CHP that the motorcyclist made an unsafe turning movement and crashed into the median. He was thrown from his bike and landed in the number one lane.
Shortly before 6:30 this morning the CHP was called to a motorcycle on fire, east of the Maze. At the scene, they found the motorcyclist dead.
"Looks like he went down on his own at this point and after he went down he was struck by a vehicle," said CHP Ofc. David Woodworth.
That driver stopped and is cooperating with the investigation. Meanwhile, the CHP is looking for the driver of an early 2000s model blue Chevy Silverado. Investigators don't know yet if that driver also hit the man or just witnessed the wreck. Either way, they want to talk to all witnesses.
"Anyone else who saw anything and especially this driver who may or may not have been involved," said Woodworth.
The CHP shut down three lanes of WB I-580 while officers investigated and cleared the scene bringing the morning commute to a standstill.
The CHP reopened all lanes shortly before 9 a.m. The motorcyclist is said to be a man, about 40-years-old, who owned a lot of motorcycles.
