Four Pomona Gang Members and Mexican Mafia Associates Found Guilty of Racketeering, Murder, Drug Trafficking, and Firearms Crimes

LOS ANGELES – Four Pomona gang members and Mexican Mafia associates were found guilty by a jury today of a series of racketeering-related crimes, including the murder of a federal inmate at the Metropolitan Detention Center (MDC) in downtown Los Angeles in June 2020.

At the conclusion of a 20-day trial, the following defendants – all of Pomona – were found guilty of one count of conspiracy to violate the Racketeer Influenced and Corrupt Organizations (RICO) Act, one count of violent crimes in aid of racketeering (VICAR) murder, and one count of first-degree murder within the special maritime and territorial jurisdiction of the United States:

• Michael Lerma, 68, a.k.a. “Pomona Mike” and “Big Mike;”
• Carlos Gonzalez, 41, a.k.a. “Popeye;”
• Juan Sanchez, 33, a.k.a. “Squeaks;” and
• Jose Valencia Gonzalez, 44, a.k.a. “Swifty.”

The jury also found Lerma and Valencia Gonzalez guilty of one count of conspiracy to distribute controlled substances (methamphetamine and heroin) at MDC and in the Pomona area. Finally, the jury found Gonzalez and Valencia Gonzalez guilty each of one count of being felons in possession of a firearm and ammunition. Sanchez was found not guilty of one count of being a felon in possession of a firearm and ammunition.

All the defendants have been in federal custody since 2018.

“These defendants were key players in a criminal enterprise that committed murder, assault, and drug trafficking,” said Acting United States Attorney Joseph T. McNally. “Today’s verdict will take these offenders off our streets and make our community safer.”

"This case makes it clear that gang violence by Mexican Mafia members and associates has not only been directed from the streets, but also from prisons in California," said Akil Davis, the Assistant Director in Charge of the FBI’s Los Angeles Field Office. “This lengthy investigation exemplifies the commitment by agencies at the federal, state and local level who've collaborated for several years on a task force to arrive at justice in this case.”

According to evidence presented at trial, from February 2012 to June 2020, Lerma – a full member of the Mexican Mafia prison gang – controlled and extorted drug proceeds from Latino street gangs in and around Pomona, as well as from incarcerated Latinos in Calipatria State Prison in Imperial County. Members of Lerma’s criminal enterprise also engaged in robberies, identity theft and fraud, drug trafficking, and other acts of violence. 

In June 2020, Carlos Gonzalez, Valencia Gonzalez, and Sanchez – at Lerma’s direction – entered the cell at MDC Los Angeles and killed a victim – identified in court documents as “S.B.” The defendants murdered S.B. in retaliation for S.B. failing to pay drug debts deemed owed to Lerma’s cell of the Mexican Mafia prison gang. 

United States District Judge George H. Wu will schedule sentencing hearings in the coming months, at which time each defendant will face a mandatory sentence of life in federal prison.

Federal prosecutors so far have secured 16 convictions in this case, including that of Cheryl Perez-Castaneda, 62, of Pomona, who is serving a 12-year prison sentence for using her power on the street as a “señora” – a high-level female associate of Lerma’s – to solicit a murder and for participating in a carjacking attempt that resulted in the July 2013 shooting of M.A.

Kelly Deshannon, 43, of La Verne, is serving a prison sentence of more than seven years for serving as a “secretary” to Lerma and for facilitating the July 2013 armed robbery of M.A. and for extortion and distributing narcotics.

The FBI’s San Gabriel Valley Safe Streets Task Force (SGVSSTF), which is comprised of agents and officers with the FBI, the Los Angeles County Sheriff’s Department, the Pomona Police Department, the El Monte Police Department, and the Drug Enforcement Administration, investigated this matter in conjunction with the FBI’s Los Angeles Metropolitan Violent Crime Task Force. The Pomona Police Department is the sponsoring agency of the SGVSSTF and has been the headquarters for the task force since its inception in 2008.          

Assistant United States Attorneys Kyle W. Kahan and Jason A. Gorn of the International Narcotics, Money Laundering, and Racketeering Section, and Assistant United States Attorney Kellye M. Ng of the Violent and Organized Crime Section are prosecuting this case.
