Miami Federal Prison Nurse Charged with Smuggling Drug-Laced Documents to Inmates

MIAMI -- Ruben Montanez-Mirabal, 32, has made his first appearance in federal court to face charges that he accepted bribes in exchange for smuggling contraband, including illegal drugs, into the Federal Detention Center in Miami (FDC-Miami) and delivering it to inmates.  Montanez-Mirabal is a licensed registered nurse who has worked for the Federal Bureau of Prisons at FDC-Miami since February 2020.   

According to the criminal complaint unsealed yesterday, from November 2021 to August 2002, Montanez-Mirabal smuggled drug-laced legal documents and other prohibited items to inmates at FDC-Miami in exchange for thousands of dollars in bribes and other things of value. It is alleged that the documents that Montanez-Mirabal delivered to inmates were sheets of paper that had been soaked in liquids containing illegal drugs, then dried.  The inmates who received the laced paper from Montanez-Mirabal then resold it to other inmates at FDC-Miami, says the complaint.  

It is alleged that in addition to money, Montanez-Mirabal accepted other bribes, such as the free use of a Lamborghini and a Rolls-Royce. 

The criminal complaint charges Montanez-Mirabal with bribery, providing contraband in prison, and possession with intent to distribute controlled substances.  His bond hearing is set for October 21 at 10:00 a.m. in federal duty magistrate court in Miami. If convicted, Montanez-Mirabal faces up to 45 years in prison.

United States Attorney for the Southern District of Florida Juan Antonio Gonzalez, FBI Miami Acting Special Agent in Charge Robert M. DeWitt, and Department of Justice-Office of Inspector General, Miami Field Office Special Agent in Charge James Boyersmith made the announcement.

FBI Miami and DOJ-OIG Miami are investigating the case. Assistant U.S. Attorney Edward N. Stamm is prosecuting the case. 

A criminal complaint is merely an accusation and a defendant is innocent until proven guilty in a court of law.
