On the night of Saturday, December 20, 2014, a night out at a bar on East 24th Street in Kansas City ended in gunfire. An altercation inside prompted staff to escort a man out; about fifteen minutes later someone returned to the bar’s back door and opened fire into the crowd. Three people were shot. One victim, 57-year-old David Brian Mostaffa, was taken to a local hospital and later died of his injuries.

Investigators focused on 56-year-old Ronald C. Vaughan of Kansas City after a credit card receipt left at the bar was linked to him. Vaughan acknowledged being at the bar and getting into a disagreement after talking to a woman, saying the bartender removed him and that he then went home; he denied returning or shooting anyone. Jackson County prosecutors charged Vaughan with first-degree murder, assault, armed criminal action, and unlawful possession of a firearm. Vaughan’s criminal history noted a 1977 rape conviction and a 2005 conviction for injuring someone while driving under the influence.

Does anyone have information about that night or knew David Mostaffa?
