California Inmate Sentenced to Five Years in Prison for Scheme to Deliver Drugs into State Prison by Drone

Michael Ray Acosta, 48, an inmate at Pleasant Valley State Prison, was sentenced Monday to five years in prison for conspiring to distribute and possess with intent to distribute methamphetamine, heroin, and marijuana inside of the prison, Acting U.S. Attorney Michele Beckwith announced.

According to court documents, from May 23 to Aug. 27, 2021, Acosta used a contraband cellphone to coordinate multiple drone deliveries of contraband into Pleasant Valley State Prison. Acosta’s co-conspirators Joshua Gonzalez, Jose Oropeza, Rosendo Ramirez, and David Ramirez Jr. flew drones over the prisons and dropped packages into the prisons. Acosta and his associates would then recover the contraband for further distribution throughout the prison population. The packages that Acosta helped to smuggle into the prisons included methamphetamine, heroin, marijuana, cellphones, cellphone accessories, and various other items. Acosta was one of five people charged federally as a result of Operation Night Drop, a multi-agency investigation that sought to prevent a rising number of drone incursions over prison facilities.

Jose Oropeza is scheduled to be sentenced on July 28, 2025, and David Ramirez is scheduled to plead guilty on the same day. Joshua Gonzalez and Rosendo Ramirez are next scheduled to appear in court on June 11, 2025.

This case is the product of an investigation by the Federal Bureau of Investigation, the California Department of Corrections and Rehabilitation, and the Federal Aviation Administration, with assistance from the Drug Enforcement Administration. Assistant U.S. Attorney Antonio J. Pataca is prosecuting the case.

The case was investigated under the Organized Crime Drug Enforcement Task Forces (OCDETF).
