The tow truck driver who was killed by a big rig in a hit-and-run incident Friday has been identified as Erwin Geremillo, 47, of Castaic.

The crash happened shortly before 8:15 p.m. in the southbound lanes of I-5, just south of Vista Del Lago Road in Castaic. Geremillo was pronounced dead at the scene.

The AAA driver was reportedly changing a tire when he was struck, according to California Highway Patrol Officer Michael Gubelli.

“The (semi truck) drifted off onto the shoulder and ran him over,” Gubelli said.

The customers, who were sitting inside the pickup truck when the driver was hit, were not hurt, according to CHP Officer Stephan Brandt.

At this time, the incident is being classified as a hit-and-run, according to CHP officials.

“The issue right now is to try and find the driver of the semi — that’s the issue,” Brandt said.

CHP officers, advised by their dispatcher to look for front end damage, checked locations at the brake stop on Interstate 5 and in Castaic without luck.

The CHP asks anyone with information on tow truck driver’s death to call the Newhall area CHP office at 661-294-5540.
