Police released surveillance photos Thursday that may help locate the driver who struck a 14-year-old boy in Santa Ana and took off over the weekend.
The boy suffered a severe brain injury in the hit-and-run, and was fighting for his life, his family said Monday.
The high school freshman, only identified by his family as Juan, was struck as he walked to school on Saturday.
The surveillance photos released Thursday morning showed a black BMW.
The driver is not visible in the photos and the license plate number is difficult to make out.
Detectives said they were searching for a 2001-2006 BMW 300 series. It has a missing mirror and fog light with damage to the passenger side fender, police said.
Police found the teen lying in the street unconscious at the intersection of Fairview Street and Civic Center Drive at 8:10 a.m. Saturday.
The boy’s family only identified him as Juan, and said he was a boy who loves science and the band "Coldplay."
He was in critical condition at UC Irvine Medical Center as of Thursday.
