Anthony Villanueva, a 20-year-old resident of Bloomington, California, was shot and killed in Rialto on the night of August 21, 2017. He was pronounced dead at the scene just after midnight following a late Sunday-night dispute that escalated into gunfire.

Police say the altercation was between Villanueva and his 19-year-old neighbor. The neighbor was arrested in connection with the shooting and charged as the investigation moved forward; authorities collected evidence and witness statements to reconstruct what happened.

Villanueva’s family and friends have been pursuing answers while the community responded in support. Does anyone have information about the events that night or knew Anthony and can help fill in missing details?
