All lanes of the Eastbound 60 freeway have reopened at Fairway Drive near Diamond Bar after a chain reaction crash involving four cars. One person died trying to help others in the wreck. Three people remain in critical condition.
The California Highway Patrol reports the crash happened around 4:30 Sunday morning.
Two cars collided and one of them — a white SUV — blocked the carpool lane facing the wrong way. Moments later, a third car traveling in the carpool lane hit the SUV and it caught on fire.
CHP officer Robert Reyes told NBC4 that passengers got out on the roadway to help the driver get out of the fiery SUV .
"As they were trying to extricate, assist the driver out of the burning vehicle, a separate vehicle, a silver mitsubishi traveling in the HOV lanes, struck the pedestrians," he said.
The cause of the crash is under investigation.
