"It doesn't appear they were target-specific or gang related," Los Angeles County Sheriff’s Department Deputy Ryan Rouzan said, adding that the investigation is ongoing.
The rampage began at around 2:15 p.m. when one person forced a woman from her Nissan Pathfinder in Pico Rivera, a community southeast of downtown Los Angeles, Fox news reported.
The two suspects then fired at three or more people in neighboring communities. Rouzan said one man shot in the rampage was taken to a hospital where he was pronounced dead.
It's unclear what the shooting victims were doing when they were shot, something Rouzan said would be revealed in the ongoing investigation.
Investigators later recovered the unoccupied SUV at a park in Whittier. The woman's condition was unknown, but Rouzan said she had not been shot.
The condition of the other victims was not immediately available.
