A teen driver who was killed Monday afternoon in San Francisco's Outer Sunset neighborhood was gunned down by a fellow motorist who fired at least six shots.

According to the San Francisco Police Department, the 15-year-old male victim was shot at 12:01 p.m. Monday at the intersection of Sunset Boulevard and Kirkham Street.

The SF Chronicle reports that the victim, who was identified by the San Francisco Medical Examiner's Office as Daly City resident Reajohn Jackson, was apparently driving a white Pontiac sedan at the time of the shooting.

"Police say a car pulled up next to the white car being driven by the teen on the busy boulevard," NBC Bay Area reports, "and someone started shooting at the white car."

The sedan's 16-year-old passenger was not injured, ABC 7 reports.

The shooting caused the vehicle to spin around, eventually resting in a southbound direction while in the northbound lane.

"At least five rounds had pierced the driver’s side," the Ex reports. Witnesses tell NBC that they heard at least six shots, and describe the car as "riddled with bullet holes."

Jackson was transported to San Francisco General Hospital, where he was pronounced dead on arrival, according to the SFPD. His death marks San Francisco's 19th homicide for 2017.

Police say that they're hopeful that area surveillance footage might reveal details of the shooter's vehicle. Speaking to ABC 7, SFPD spokesperson Officer Giselle Talkoff said "There was talk of a mention of a vehicle in that area at that time so at this time we're going to try to see if there's anything related that we can find."

According to police officers who spoke with NBC, it's believed that Jackson was targeted, but a motive is not yet apparent.

Area resident Rose Widness tells NBC that she drove through the intersection just moments after the shooting.

"We went to the corner and saw the young boy lying there, and we didn't know if he was alive or dead," she said. "We thought it was a car accident. It's kind of scary. You don't expect things like that happening in your neighborhood."

Derek Hom, a parent of a student at nearby St Ignatius High School, disagreed. "I know things can happen," he told ABC 7 regarding the shooting, which caused a lockdown at the school. "It doesn't really matter what neighborhood. It can happen anywhere."
