Gabriel Rodriguez, 35, was found fatally shot in the torso on January 10, 2018, in a parking lot near Cross Creek and Walzem Road in San Antonio, Texas. He was discovered not far from his vehicle; police identified his death as the city’s first homicide of that year.

Investigators say the killing was a drive-by shooting linked to retaliation. Reports state Rodriguez had been involved months earlier in a heated argument and physical altercation with a woman who was later identified as the mother of the accused shooter. Authorities say that woman orchestrated the attack and that the shooter used an AK-style rifle; more than 30 rifle shell casings were recovered at the scene.

Ethan Gonzales was implicated in the shooting and arrested and charged with murder; the woman involved died in a car crash while fleeing the scene. What details about Gabriel’s last hours or the people around him could help explain how this retaliation escalated to deadly violence?
