Adrian Jasso, 27, of Abilene, Texas, was shot and killed during a fight at MC Sports Bar and Taqueria on January 20, 2019, at about 1:30 a.m. Surveillance footage showed a single shot struck Jasso in the head. Eusabio Jose Perez Jr., 21, was arrested shortly after the shooting and admitted to firing the shot, saying he shot the old dude.

Perez was charged with murder, later pleaded guilty in October 2019, and was sentenced on January 2, 2020, to 75 years in prison. The family expressed relief at the sentence and a sense of justice, and the district attorney spoke about the long-lasting consequences of such violence.
