Authorities have identified the man killed Friday on Interstate 5 in San Clemente when a piece of a brake drum crashed through the windshield of a sport-utility vehicle as Ruben Serrano Jaramillo, 21, of Santa Ana.
Serrano Jaramillo was a passenger in the SUV driven by his brother, Orange County supervising deputy coroner Joseph Luckey said Sunday.
Serrano Jaramillo was talking to his brother Friday evening when he was hit in the head by an object investigators identified as a part of a brake drum. The brother was pelted by glass shards from the impact, but he survived. Authorities did not release the brother's name.
The accident occurred in the southbound lanes near Avenida Vista Hermosa in San Clemente about 8:50 p.m. A spokesman for the California Highway Patrol said the brothers' vehicle was traveling about 70 mph.
So far, officers have been unable to find the big-rig that lost its brake drum, the spokesman said.
