On August 15, 1995, several drivers noticed Martinez because of his excessive speed on S.R. 87. One couple passed him just after Officer Robert Martin had stopped him and was approaching the stolen Monte Carlo. Martinez shot Officer Martin four times and took his service revolver.
Due to Martinez's reckless, high-speed driving while fleeing the scene, several other drivers took down the Monte Carlo's license plate number. Martinez fled to California, where the police arrested him a day later and recovered the murder weapon and Officer Martin's service revolver.
After his arrest, Martinez was overheard during a telephone call bragging to a friend-and laughing-that he had killed a cop. Tests revealed that at least one of the bullets that struck Officer Martin was fired from Martinez's tape-wrapped revolver.
