Antonio Tony Aguilar, 32, was shot dead on November 22, 2015, at Ruben Salazar Park in East Los Angeles while playing basketball with his brother Juan Johnny Aguilar. Witnesses say three people approached the brothers — a heavyset Latino man, a heavyset Latina woman, and a Latino teenager — and after a brief conversation the man produced a handgun and shot both brothers multiple times. Tony was pronounced dead at the scene; Juan died shortly after at a nearby hospital.

The park was busy at the time and investigators interviewed more than 50 witnesses. The three suspects fled in two vehicles, described as a dark-colored SUV and a two-door sedan, last seen driving south on Ditman Avenue. Authorities noted Juan Aguilar’s gang membership and considered whether the killings were gang-related, but it remained unclear whether the brothers were specifically targeted or knew the attackers.

Anyone who was at Ruben Salazar Park that day or who has information about the two vehicles, the three people seen approaching the brothers, or why Tony and Juan might have been targeted is asked to come forward.
