Matthew Winkelman, a 30-year-old Hispanic man, was shot and killed on February 12, 2015, in San Antonio after an argument outside a parking lot. The confrontation involved Alberto Delatorre; witnesses and the investigation described Delatorre escalating the dispute by yelling obscenities, threatening Winkelman to fight, and then shooting him. Delatorre asserted he acted in self-defense.

The case went to a jury trial that highlighted whether deadly force was justified. The prosecution disputed the self-defense claim and argued Delatorre’s actions were not justified. The jury ultimately found Delatorre guilty of murder and the court imposed a sentence.

The case raises questions about how a verbal confrontation outside a parking lot turned lethal and how prior threatening behavior factored into the outcome. Does anyone have information about the incident, witnesses, or the events that led up to that night?
