John Martinez, 45, was shot and killed in the driveway of his Houston home on October 13, 2012. He had been returning from a visit with his brother late that evening when assailants attacked him, shot him multiple times, and stole his wallet and cell phone. His wife Norma Martinez and a son were inside when they heard the gunfire and found John unconscious and bleeding at the door.

Investigators believe the attackers may have followed Martinez home, possibly intending robbery or an attempted break-in. The family says John tried to protect his loved ones during the attack. Norma has continued to press for answers, posting a billboard on Interstate 45 and offering a reward through Crime Stoppers for information. The Houston Police Department and its Cold Case Squad are handling the investigation, which remains unsolved.

Anyone with information about John Martinez’s death is asked to contact the Houston Police Department or Crime Stoppers.
