In or about 2006 or 2007, Vazquez-Baez alerted La ONU members that Freddy Mendez-Rivera, a local resident, had complained to police about drug dealing occurring in his neighborhood, which led to members of La ONU kidnapping and then killing Mendez-Rivera. Around the same time, Vazquez-Baez alerted a senior member of La ONU that the kidnapping was being reported over the police radio. Vazquez-Baez advised that, because the fact that Mendez-Rivera had spoken with the police was known throughout the Carolina Narcotics division, it was important that the body never be discovered. When later updated about what had happened, Vazquez-Baez laughed and remarked, in substance, that Mendez-Rivera would not be giving the police information any further.
On or about May 9, 2007, members of La ONU hired Vazquez-Baez to participate in the murder of Anthony Castro-Carrillo in Carolina, Puerto Rico, in exchange for a cash bonus. Vazquez-Baez and members of La ONU stormed Castro-Carrillo’s residence while dressed as police officers and shot and killed him.
In or about 2007, Vazquez-Baez delivered a confidential informant, who was in Vazquez-Baez’s custody, to members of La ONU, who pretended to be other police officers. Those members of La ONU then shot and killed the informant.
The case was investigated by the U.S. Postal Inspection Service, the Drug Enforcement Administration, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the New York City Police Department. The United States Attorney’s Office in the District of Puerto Rico and the Puerto Rico Police Department also supported the ongoing investigation.
