A hit-and-run collision on southbound Interstate 5 in Chula Vista ended in a shooting, California Highway Patrol officials confirmed.
It all began just before 4 a.m. on the E Street off-ramp on southbound I-5.
CHP said two victims in a black Mercedes sedan came to a stop at the off-ramp and were rear-ended by a Nissan Altima.
The Nissan Altima then pulled up alongside the Mercedes and a discussion between the occupants of the two vehicles ensued about who was responsible for the accident, authorities said.
The driver of the Mercedes allegedly told the driver of the Nissan to pull over so they could exchange information, but the driver of the Nissan refused.
CHP said the driver of the Mercedes then told the driver of the Nissan they were going to call police.
An occupant from the Nissan then pulled out a gun and began firing shots at the Mercedes, according to authorities.
The Mercedes was shot at three times but the passengers were not injured. The suspect vehicle fled the scene.
CHP officials said the shooting suspect is described as a bald Hispanic male in his early to mid-20s with a large tattoo on his forehead.
Anyone with information is urged to contact CHP at (858) 637-3800.
