Ronald Casillas Jr., a 24-year-old Hispanic man, was shot and killed on April 8, 2014, during a violent altercation that began as a possible drug deal. The confrontation escalated into a shootout at a park near Horal and Revlon streets on the west side of San Antonio. Casillas and another person were shot; Casillas was pronounced dead at the scene.

Twin brothers Davonne and Javonne McFadden, both 18, were arrested on suspicion of murder after police say they were involved in the shootout. The brothers were pulled over for a minor traffic violation and officers found weapons in their car; they were booked into the Bexar County jail on $250,000 bond. Authorities continued to seek additional persons of interest as the investigation remained active.

Casillas is remembered by family and the community as a beloved son and hero. Does anyone who was in that neighborhood that day or who knew Ronald have information that could help fill gaps in the timeline?
