SAN DIMAS >> A man violently carjacked an elderly man outside a San Dimas restaurant Saturday before deputies, aided by the truck’s OnStar system, tracked down the vehicle, disabled it remotely and took the suspect into custody, authorities said.
The carjacking took place at 7:22 p.m outside a Red Robin restaurant, 565 W. Arrow Highway, Lt. Tonya Edwards of the sheriff’s San Dimas Station said.
The suspect, a man in his 20s, attacked a 74-year-old man and yanked him from his 2015 Chevy Silverado, Lt. Elisabeth Sachs said.
“(The suspect) struck him, knocked him to the ground, and stomped on his head,” she said. “The victim fought back, but the suspect was able to overcome him and drove off in his vehicle.”
Authorities were notified of the carjacking minutes later through OnStar, according to Lt. David Buckner, watch commander of the Los Angeles County Sheriff’s Walnut Station, whose deputies assisted in taking the suspect into custody.
An OnStar operator provided the sheriff’s department with “up-to-the- moment locations” of the white pickup truck, then remotely slowed it to about 5 mph after deputies spotted it heading south on the 57 Freeway.
The driver got out of the car and surrendered near the 91 Freeway about 8 p.m., Buckner said.
“He stole the wrong vehicle,” Buckner said.
Joshua Frontino-Deaton, 26, was booked on suspicion of carjacking, Sachs said. His city of residence was not available Sunday afternoon.
The carjacking victim was treated at a hospital for injuries and released later in the day, Sgt. Joe Bolanos said.
According to county booking records, he was being held in lieu of $100,000 bail pending his initial court appearance, scheduled Tuesday in Pomona Superior Court.
