Acting Chief Isaac Benjamin Martinez, 33, was killed on April 10, 1994, while serving with a 10-man SWAT team in San Ildefonso Pueblo, New Mexico. The team was serving a warrant for a firearms violation when the suspect opened fire as officers entered. Martinez was struck seven times and died from his wounds; the SWAT team apprehended the suspect at the scene.

Martinez had eight years in law enforcement and had been serving as Acting Chief for three weeks. He left behind a son, his parents, and three siblings. The suspect was later acquitted at trial on grounds of self-defense. Martinez is commemorated at a Law Enforcement Memorial designed with Native American traditions in mind.

What details about the operation or the trial might help explain how the acquittal occurred, and can anyone with knowledge of this case provide additional information?
