Andrew Martin-Jimenez was 19 when he was killed in the early hours of April 21, 2018, on the South Side of San Antonio. Police say an SUV found riddled with bullet holes at Interstate 35 and Highway 16 contained two young men — a 20-year-old shot in both arms who was hospitalized in stable condition and a 21-year-old who was detained — and that officers later discovered Andrew dead on the sidewalk in front of his home in the 1400 block of Villeret Boulevard.

Authorities described the encounter as an argument that escalated into a shootout after the men in the SUV drove to Andrew’s block and began talking with him; investigators said at the time they had not determined who fired first. Andrew’s mother, Paula Martin, said she sheltered in the kitchen during the shooting, found her son unresponsive, and later stated no weapon was found on him. She also suggested one of Andrew’s friends may have fired at the SUV and left before officers arrived.

The initial reporting left a clear uncertainty about who started the gunfire and whether Andrew was armed. No publicly reported arrest, indictment, or conviction tied to his killing was identified in the contemporaneous coverage. If anyone knew Andrew, his movements that night, or has information about the people in the SUV, please come forward with tips.
