Aarón Baray Nava was 20 and a student of Economics at the Universidad Autónoma de Ciudad Juárez when he was killed on July 20, 2015, in Ciudad Juárez. He was described by his family as the younger brother and was active in his church. The shooting happened in the early hours of July 19, 2015, after Aarón and two other young men left a nightclub and were riding in a Toyota pickup truck in the Fuentes del Valle neighborhood.

Aarón and Damián Alexander Alemán Valdez were killed instantly; a third occupant, Alexis Cano, died of his wounds several days later. Investigators identified París Lau Campbell, the son of a former rector of the university, as the primary suspect; at the time there had been no arrest warrant and Paris remained at large. No arrests were reported immediately after the attack. If anyone knew Aarón, the other victims, their movements that night, or can provide information about the shooting, please come forward.
