On January 14, 2021, 42-year-old restaurant owner Oscar Acosta was shot and killed outside his south Wichita eatery, Birrieria Tito. The confrontation began when a man was seen rummaging through a trash can inside the restaurant and was asked to go outside. After the trash can was dumped over, an argument between the man and an employee escalated and Acosta went outside to intervene. The man produced a handgun and fired one shot, striking Acosta in the chest. Acosta staggered back into the restaurant, warned family and customers to take cover, and then died of his wound.

Witnesses directed police to a suspect a couple of blocks away. Officers arrested 26-year-old Adrian Nicholas Zongker and found him in possession of a firearm; he was booked on suspicion of first-degree murder and being a felon in possession of a firearm. Reports say the defendant had prior convictions including criminal possession of a firearm and aggravated assault and had been recently paroled. A jury later convicted Zongker of first-degree premeditated murder; a judge sentenced him to life with parole eligibility only after serving 50 years, plus an additional 15 months for the weapons charge to be served consecutively.

Did anyone who knew Oscar, worked at Birrieria Tito, or was in that neighborhood that afternoon see anything that could help clarify how the argument escalated to gunfire?
