Reimundo Rey Camarillo Jr. was 31 when he was found bleeding and face down in an alley behind his East Chicago home in the 4200 block of Euclid Avenue on the morning of October 12, 2015. An autopsy confirmed a fatal gunshot wound to the back.

Within two days, East Chicago City Councilman Robert Coop Battle was charged in the killing. Investigators said Camarillo and Battle argued outside Battle’s residence that day; prosecutors alleged the dispute concerned a drug debt and tied Battle to drug trafficking. Officers at the scene reported no knife or other weapon, despite an early defense claim that Camarillo had brandished a knife.

Federal authorities later expanded the case, charging Battle in a conspiracy to distribute cocaine and saying Camarillo’s death furthered that enterprise. Battle pleaded guilty to discharging a firearm during and in relation to a drug trafficking crime that resulted in Camarillo’s death and received a 20-year federal sentence followed by two years’ supervised release. Anyone who knew Rey Camarillo or has information about his life or death is asked to come forward.
