CORONA--A case of ‘road rage’ is at the center of an officer-involved shooting that left a motorist dead.

Investigators have made no arrests in the wake of the incident.

The off-duty LAPD officer, Antonio Mendez, claims the other motorist, Robert Scott Day, 50, of Santa Ana, sideswiped his Hummer and then sped off down Interstate 15 with the officer in pursuit.

Sheriff’s spokeswoman Herlinda Valenzuela explained what happened when both men drove into a parking lot on Temescal Canyon Road.

“Both drivers exited their vehicles and a verbal confrontation ensued. The off-duty officer attempted to detain the hit-and-run suspect and there was an officer-involved shooting.”

Day was hit once and died minutes later at a Corona hospital.

There was no indication he was armed.

A child in the officer’s Hummer was not injured. Mendez, who's been with the LAPD for two years, has been placed on leave.
