The Milpitas police concluded a high-speed chase in Fremont when the suspect, believed to be involved in the death of his ex-girlfriend before escaping, crashed the vehicle near Warren Ave., east of Kato Drive on Sunday afternoon, SFGATE reported.

The San Jose man, 42, sustained what the police said were “self-inflicted” injuries and was brought to the hospital for treatment.

At 12:42 in the afternoon, Milpitas police got a call asking for help as the victim told the caller that her ex-boyfriend could be tailing her.

Officers found the car of the victim driving at top speed from a parking lot.

There were reports that the vehicle carries a dead female.

A chase was initiated into Fremont and ended when the suspect crashed the car.
