"We just lost our hero. He was the pillar of our family," said Jose Gallegos, the victim's son.
The accident happened around 9 p.m. Saturday as Gallegos crossed the street in the area of Pickering Avenue near Hadley Street.
Whittier Police Lt. Kent Miller says witness saw a white Toyota Tacoma hit a pedestrian. They followed the suspect's vehicle and were able to get photos and other details about the truck.
On Sunday, a Hacienda Heights resident called authorities after spotting a suspicious vehicle in her neighborhood. Police found blood and evidence of a collision on the vehicle and identified the owner as 30-year-old Randy Marquez.
Marquez is being sought as a "person of interest."
"If it was an accident, that's one thing. I could forgive that," said Jose Gallegos. "But that was no accident."
Gallegos' wife of 26 years says he served in the Army as a combat medic and was a proud veteran.
"Victor was kind and caring and loved everybody that he met," said Gloria Gallegos.
Police and the family are hoping the hit-and-run driver will surrender.
"We want justice," Jose Gallegos said. "We want this to come to an end and be able to bury my father in a proper way."
Anyone with information on the driver was urged to contact the Whittier Police Department at (562) 567-9240.
