In 2010, an FBI investigation uncovered a conspiracy to distribute cocaine, heroin, marijuana, Percocet, and Xanax to an inmate at MDC Guaynabo. Several conspirators, led by Juan Rios-Ortiz, also attempted to provide cellular telephones, chargers, and SIM cards to an inmate of MDC. Rios-Ortiz worked for a company that had a contract to supply produce to the prison kitchen. Rios-Ortiz was subsequently convicted of conspiracy to distribute controlled substances, distribution of controlled substances, and providing contraband to an inmate of a federal prison.
On February 26, 2013, Osvaldo Albarati, a lieutenant for the Federal Bureau of Prisons, was shot and killed in what is believed to be retaliation for his investigations into cellphone smuggling at MDC Guaynabo. He had just left the facility and was driving home when several gunmen opened fire on his vehicle on the De Diego Expressway near Bayamon. Albarati worked in the investigative branch at the prison, where he was responsible for investigating crime within the prison, including drug smuggling and illegal cellphone use. Authorities have said his killing may have been contracted by powerful drug kingpins being held at the facility in reprisal for recent seizures he spearheaded. The FBI is investigating the killing and no charges have been filed.
