Adrian Reyes Valdez Avila, 24, was shot and killed on July 9, 2019, at an apartment complex near 29th Street and Roeser Road in south Phoenix. He was found with multiple gunshot wounds and later died at a local hospital. Adrian was a father of four; his family remembered him as funny, kind-hearted, and willing to help others.

Police say a verbal altercation took place among a group just before the shooting. Investigators identified two people running from the scene, and an anonymous tip stated Adrian had been at the home of a known street gang member and that the member’s son had argued with Adrian the day before over a firearm. On July 31, 2019, 20-year-old Richard Lee Mitchell Chambers was arrested at his Phoenix residence and held on suspicion of second-degree murder; he reportedly denied involvement.

Does anyone with knowledge of that neighborhood or who knew Adrian have information that could shed light on what happened?
