Guadalupe Acuna was 42 when he died on September 11, 2018, in San Bernardino, California. Born March 15, 1976, in Los Angeles, he was remembered by friends and family and services were held at Green Acres Memorial Park & Mortuary in Bloomington with a visitation on October 3, 2018, and a funeral mass on October 4, 2018, at Our Lady of Guadalupe Catholic Church in San Bernardino.

Investigators linked his death to a broader criminal network operating in the San Bernardino area that was associated with the Mexican Mafia. The inquiry unfolded into a larger operation: the FBI and local police carried out raids and arrests, and several people were indicted on charges including narcotics trafficking and firearms violations. Authorities reported the group had been extracting taxes from local drug dealers and that its activities contributed to violence and disruption in the community.

Anyone with information about Guadalupe Acuna, his last movements, or connections to the criminal network in San Bernardino is asked to come forward.
