A late-night neighbor dispute in Tucson turned fatal on July 24, 2022. Neighbors at an apartment complex on East 22nd Street got into a verbal altercation that escalated into a physical fight and then gunfire. Both brothers involved were killed: 34-year-old Michael Espinoza was found with gunshot wounds and pronounced dead at the scene, and his 30-year-old brother Mark Espinoza was taken to St. Joseph’s Hospital with life-threatening injuries and later died.

An adult male neighbor, identified as Carlos Ruiz, approached officers at the scene and told them he had been involved in the shooting. The victims’ sister said Ruiz had been taunting the brothers while they were leaving their apartment and appeared to be under the influence when the confrontation began.

Did anyone in the neighborhood see what led the confrontation or the moments after the shooting?
