The search continued Sunday for the driver of a "party bus" that struck a man in a Norwalk hit-and-run, dragging him more than 200 feet and leaving him with major injuries, according to authorities.
The victim, identified by family members as 26-year-old Efren Virgen, remained hospitalized in critical condition at St. Francis Medical Center in Lynwood.
"He's very precious to us. We're a very tight family," said the man's sister, Catalina Rolon Virgen. "For this to happen to him … I just can't even believe it."
The victim was walking on Fairford Avenue, south of Ratliffe Street (map), about 2:31 a.m. Saturday when he was hit by the southbound bus, the Los Angeles County Sheriff's Department said.
A witness told investigators that he heard music coming from inside the bus at the time and saw its interior lights flashing. Such vehicles are rented to groups for bachelor and bachelorette parties, birthdays, proms and other events.
The black bus was last seen turning westbound on Foster Road.
"We believe that the driver knew that he struck someone," sheriff's Sgt. Jack Jordan said. "We're looking for anyone who was on the bus to come forward with information that can lead to his identification."
Efren Virgen is a husband and father of two daughters, ages 3 and 8, according to relatives.
"We just hope that he gets better and that they catch this person, because it's horrible," his sister said. "An animal would do this."
The victim's brother told KTLA on Sunday that Virgen was breathing on his own after being taken off life support.
