Gilberto García Mena (born 1954), also known as El June, is a Mexican convicted drug lord and former high-ranking member of the Gulf Cartel, a criminal group based in Tamaulipas, Mexico. He began his criminal career as a small-time marijuana smuggler in his teens, and later joined the Gulf Cartel under kingpin Juan García Ábrego. García Mena was arrested by U.S. authorities in Texas while possessing marijuana in 1984, but was released without a conviction. He returned to Mexico, and established a center of operations in Nuevo León. García Mena was arrested on drug-trafficking charges in 1989, but authorities were again unable to convict him. Released in 1990, he rejoined the Gulf Cartel.
