[2] MCC San Diego is an administrative facility designed to house federal prisoners of all security levels, including both male and female offenders.

[4] On March 18, 2011, the office of Laura E. Duffy, the US attorney for the Southern District of California, announced that Brandon McKinney, a former correctional officer at MCC San Diego, had been indicted on suspicion of having sexual relations with a female inmate while on duty on July 20, 2010.

Since sexual relationships between prison staff and inmates are prohibited by law regardless of consent, McKinney was terminated and charged with assault.

Borja was originally indicted on the methamphetamine trafficking charge following his arrest in January 2012 as part of Operation Carnalismo, an investigation into the Mexican Mafia gang.

Borja also admitted in his plea to concealing heroin inside his body while he was at MCC San Diego and planning to distribute it to other inmates before it was discovered by correctional officers.
