Rafael Mancilla Robles, 34, was killed in San Diego on April 11, 2013. His death was connected to transnational cartel activity, investigators saying the homicide formed part of broader violence tied to drug trafficking and related crimes operating across the U.S.-Mexico border.

Twin brothers Anibal and Edward Avila were identified as suspects in the shooting. The brothers reportedly fled to Mexico shortly after the incident and were later apprehended in connection with the crime. Authorities linked the Avilas to organized crime groups, including the Fernando Sanchez Organization, described as an offshoot of the Arellano-Felix cartel.

The case fed into a larger multi-agency probe called Operation Luz Verde, which targeted kidnapping, murder, drug trafficking and other cartel-linked crimes and used wiretaps and other investigative methods. Anyone with information about Rafael Mancilla Robles or his death is asked to come forward.
