An investigation is continuing Friday into a fatal car-to-car shooting that left one man dead and another injured on the Golden State (I-5) Freeway in the Boyle Heights area, which caused a freeway closure and heavy traffic during Thursday evening's rush hour.

The shooting was reported in the northbound lanes near Lorena Street around 4:10 p.m. on Thursday, according to the California Highway Patrol (CHP). At least one other vehicle also appeared to have its rear window shattered. ABC News San Diego reports.

According to the CHP, a Dodge Durango and a gold Cadillac sedan were driving in the northbound lanes when the Cadillac rear-ended another vehicle. Two men then exited the Durango and began shooting at the two occupants of the Cadillac, whose driver made a U-turn on the freeway but eventually crashed into other vehicles before coming to a stop. 

A passenger in the Cadillac was pronounced dead at the scene, CHP Officer Sean Lough told City News Service, while the driver was taken to a hospital in an unknown condition. The shooters fled the scene and are being sought by authorities.
