One person was killed and three others were hospitalized after a collision involving a semi-truck and a sedan in Los Angeles County on Tuesday.

Authorities responded to the scene at South Bonnie Beach Place and Bandini Boulevard in Vernon around 3:39 p.m.

The driver of the sedan was pronounced dead at the scene, the Los Angeles County Fire Department confirmed. Their identity has not been released.

Three other people — two children and a female — were transported to a local trauma center for treatment.

Sky5 images show a sedan crushed beneath a large semi-truck in the middle of an intersection.

The sedan’s roof and windshield appeared completely crushed after the collision.

Firefighters worked for some time to extricate all passengers from inside the crushed sedan.

The cause of the deadly crash remains under investigation.
