The video, which was recorded on the driver's camera, may serve as a critical clue to help police track down the suspect. The footage shows a man with a handgun getting in the backseat of his car on May 11 at the ARCO station at Rush Street and Rosemead Boulevard in South El Monte around 9:20 p.m.
The suspect is seen arguing with the driver, 67-year-old Paul Liao, for more than a minute in the video. He demands money and grab's the driver's cellphone. He also apparently tried to get the driver to leave the car but after some discussion the driver was apparently able to dissuade the suspect from stealing the car.
He handed over the wallet, which held $1,560 in cash, according to his family. Twice during the encounter the suspect beat the driver in the face with the gun, leaving him with a bruised and bloody nose.
The driver's family has established a GoFundMe to help replace the stolen cash and cellphone as well as help with medical expenses.
The suspect remains on the loose.
Authorities are investigating the case as a possible hate crime.
Anyone with information is asked to contact the Los Angeles County Sheriff's Department.
