Donald Riley, also referred to as Donald Riley Jr., was shot and killed at a residence in the 1100 block of 8th Avenue in Terre Haute, Indiana, on the evening of Saturday, September 3, 2022. Witnesses heard a motorcycle arrive, then a conversation or argument in the backyard between Riley and another man that ended with a single gunshot. Riley was transported to a local hospital and pronounced dead.

Investigators quickly focused on Richard Tony Sandlin as a person of interest after eyewitnesses identified him from a photo lineup. A multi-agency search followed; Sandlin was arrested in Northern Vigo County near Gallagher Road and Rio Grande Avenue on the night of Wednesday, September 7, 2022, and booked on a murder charge. Prosecutors said evidence showed Sandlin shot Riley after the dispute; Sandlin claimed self-defense and alleged prior sexual battery by Riley, but the court rejected those justifications.

Anyone with information about Riley, the events that evening, or the location on 8th Avenue in Terre Haute is asked to come forward.
