Ontario police were called to a home on the 1000 block of East Sixth Street where a man with a gun was believed to be holding his girlfriend at gunpoint.
Police surrounded the multi-unit building.
As officers were attempting to make verbal contact with the female victim, Martin was seen fleeing in a white Honda Accord from a rear garage.
At the same time, the police department armored assault vehicle was arriving at the scene.
The vehicle blocked the suspect from driving away.
The suspect's car actually collided with the front end of the assault vehicle.
The assault vehicle pushed the car into an adjoining garage in an effort to prevent his escape.
Investigators say at this point, Martin stepped out and pointed a pistol at officers. Fearing for their safety, two officers fired their weapons, striking the suspect in the upper body.
Investigators say the suspect was wearing a bulletproof vest.
Trapped in his car in the garage, he refused to surrender.
Police conducted verbal negotiations and the suspect finally gave up.
Martin was transported by ambulance to an area hospital where he later died from his injuries.
The nature of those injuries is unclear.
Investigators say Martin had a loaded TEC-9 assault pistol and was wearing a bullet proof vest.
Martin was recently released from prison and was on parole for a prior domestic violence conviction.
Martin was a gang member out of Riverside County with a lengthy criminal history that includes resisting arrest, domestic violence, robbery, carjacking, hit and run, DUI and felony assault on a peace officer.
