CHULA VISTA, Calif. — A driver reported to be unconscious with a head injury crashed into a brick wall and died Monday in Chula Vista, authorities said.

Chula Vista police received several 911 calls around 3:26 p.m. about a car that crashed into a wall on the 600 block of Hilltop Drive, Chula Vista police Agent Brian Carter said in a news release. When officers arrived, police said they found a male driver in a Volkswagen Passat and removed him from the vehicle to begin lifesaving efforts, but he ultimately succumbed to his injuries about 30 minutes later.

No other passengers were in the vehicle at the time, according to Carter.

“Witnesses at the scene stated the vehicle was initially stopped for a red light at the intersection of East J Street and Hilltop Drive,” Carter said. “The light turned green and the driver remained stopped. After several seconds, the driver sped off northbound on Hilltop Drive. The vehicle veered to the right, drove across a driveway, struck a tree and then collided with a brick wall.”

Investigators are unsure if the driver had a medical condition that contributed to the crash, but they have considered speed to be a factor, police confirmed.

Those with information to share with investigators about the incident were asked to call Chula Vista police at 619-691-5151.
