A birthday party on the corner of Douglas and Estelle in Wichita, Kansas, turned deadly in the early hours of July 8, 2015. Richard Romero, a 49-year-old Hispanic man, was shot in the upper chest shortly before 3 a.m. Medical personnel arrived but Romero’s wound proved fatal; he was pronounced dead about 15 minutes after the shooting.

The Wichita Police Department arrested two men in connection with the homicide: 45-year-old Teveere Royce Bates and 52-year-old Isaac X. Riverson. Bates was charged with intentional second-degree murder; a jury later found him guilty and he received a sentence exceeding 54 years. Prosecutors did not file charges against Riverson at that time, but left open the possibility of revisiting the case if new information emerged.

Did anyone at the party or nearby that night see something that could still help clarify how the shooting unfolded?
