One of the witnesses to a crash in 4S Ranch said the victim's car was traveling "like a missile" moments before the collision.
The fatal collision happened just before 6:30 p.m. Wednesday at the intersection of 4S Ranch Parkway and Camino Del Norte.
Sam Kambo was in his car, following his wife who was driving a black Lexus when she made a southbound turn onto 4S Ranch Parkway.
Kambo said a red Ford clipped their car, rolled over and slammed sideways into a light pole.
"It just came like a missile and just a little touch to that black vehicle and it hit the pole and it's in two pieces," he recalled.
Aerial video showed an overturned vehicle had collided with a large street sign pole. A second car, the vehicle belonging to Kambo’s wife, was stalled near the scene and appeared to have minor damages.
The crash closed the intersection for several hours and drew crowds at each corner.
The driver of the red Ford Escape, described by officials as a man in his 50s, was pronounced dead at the scene.
'It's very sad you don't want to see anybody passing away like that," Kambo said.
The Escape’s female passenger was transported via Mercy Air to Palomar Hospital with major injuries, officials confirmed.
Kambo says his wife was not injured in the fatal collision.
The cause of the collision is under investigation, and officials are trying to determine whether speed played a factor.
CHP investigators say both the Ford Escape and the Lexus entered the intersection at the same time and collided. The impact caused the Ford to overturn and strike a light pole in the southeast corner of the intersection.
The California Highway Patrol said this was the first fatal accident in the intersection but residents who live nearby say it's a busy area, and traffic here moves fast.
If anyone witnessed the fatal crash or has any information on this, the CHP asks that they Officer H. Corbin at (619) 220-5492.
