Sergio Cavazos Garcia, 56, was shot and killed during an attempted robbery at his northeast Houston home shortly after midnight on May 11, 2008. Two armed men arrived in a dark-colored vehicle; one armed with a shotgun went inside and confronted Garcia and another person while the second suspect stayed at the door. An altercation left Garcia dead and his son, Sergio Garcia Jr., wounded; the son survived.

The suspects fled in separate vehicles described as a dark-colored SUV and a white vehicle. Neighbors told police there had been constant activity at the Garcia home, a detail investigators say may be relevant.

Houston police are asking anyone with information to come forward — did anyone hear or see anything that night or know who might be responsible?
