Witnesses say as many as 15 vehicles stopped and helped during the accident.

"It was Supposed to be a special day. You could tell the boys where all very united because they all pulled over, trying their best to help,” says Bianca Gallegos who witnessed the deadly crash.

“I saw young kids getting off their cars. Some were holding their heads, others were running from the far right side of the freeway to the far left lane to where the car was,” she added.
