Tough guy Michael Oso Contreras would later be arrested by Mexican Police, who did not respect the protection provided American citizens by the U.S. Constitution and amendments. He was "persuaded to confess" to being a terrorist and a gun runner. When he was returned to U.S. custody he was also confused about his gender. He became a prison "Queen" and was then known as "Chi Chi" Contreras. Nevertheless, he remains a very dangerous person.
In the 1990s, OSS formed a task force in South Los Angeles targeting the notorious Florence 13 transnational gang. At the time, the F-13 was at war with the 38th Street gang, and the LAPD's C.R.A.S.H. (Community Resources Against Street Hoodlums) gang unit, in cooperation, targeted 38th Street. The 38th Street gang became nationally known in the 1940s for the "Sleepy Lagoon" murders and the Zoot Suit Riots of 1943.
At the time, my prison gang unit was part of a federal task force targeting the Mexican Mafia in Los Angeles. We successfully prosecuted three RICO cases against the prison gang. During the investigation we learned that Florencia 13 gang member Juan "Topo" Garcia was also a member of the Mexican Mafia and had control over a large portion of the Los Angeles County jail system. While an inmate, he was implicated in at least two jailhouse executions. The cases could not be prosecuted because other inmates in the jail controlled by the Mexican Mafia did not want to be witnesses against the EME. Garcia hit the streets a free man.
The Los Angeles Sheriff's OSS Gang Task Force targeting the F-13 gang soon received information that Topo Garcia was now directing the F-13 gang to enforce Mexican Mafia orders to tax all Piasas drug dealers, to tax Sureño gangs, to kill rival blacks and run them out of the city, and to tax "Mica Mills" (counterfeit document mills) that produce fake identification and immigration documents.
Our intelligence told us that Topo organized a system of enforcers and extortion teams from the most violent Florencia gang members. In addition, Title III wire taps had been activated by our Mexican Mafia Task Force and they confirmed the reports. But there was not enough evidence to get the U.S. Attorney's attention.
