"The first thing is, it's too dark," said Fernando Corres, a supervisor at nearby A.J. Market. "People are driving too fast. (Government) needs to pay more attention. (But we're) poor people. They don't care."
The incident occurred near Cedar and Santa Ana avenues, coroner's officials said.
The deputy was driving south in the 11000 block of Cedar Avenue at 9:14 p.m. when his vehicle collided with 54-year-old Alfredo Berumen of Bloomington.
Berumen was walking east across Cedar Avenue, coroner's officials said. He died at the scene.
According to California Highway Patrol, which is investigating the incident, the deputy was responding to a call and was driving at an unknown speed.
Berumen was crossing Cedar Avenue outside of a marked crosswalk, just south of Santa Ana Avenue.
He had just crossed from the west side of Cedar Avenue and was in the No. 1 lane of the southbound side of Cedar Avenue, CHP officials said.
According to the CHP, the man "for unknown reasons", walked into the path of the deputy's vehicle and was struck.
The force from the collision threw him in a southerly direction, where he landed in the No. 1 lane of southbound Cedar Avenue, CHP officials said.
Emergency medical personnel pronounced the man dead at the scene.
The deputy was taken to a local hospital and treated for a brokern arm, officials said.
Those who heard of the collision said it wasn't surprising because the street is poorly lit.
The CHP is still investigating the crash.
