It happened late Saturday night on the westbound 210 Freeway just west of the Irwindale on-ramp. A 39-year-old man from Azusa was killed.
It appears the man either jumped or fell from a car. He was then hit by several other vehicles. Several lanes had to be shutdown but have since reopened.
An autopsy is planned to determine exactly how the man died. His name has not yet been released.
