Episode 211: Billy Ebersole and Ossie DeJesus – Colombian Cocaine Undercover Sting

In this episode of FBI Retired Case File Review, Billy Ebersole and Ossie DeJesus review the Tratados Quimicos (Chemical Treatments) case, where a Colombian drug trafficking cell had a shipment of 1000 kilograms of cocaine with a street value of $25 million hidden inside big metal chlorine gas containers at Dundalk Terminal near Baltimore.

Billy, the case agent of this Colombian cocaine undercover sting, had his informant introduced Ossie, the undercover agent, to the traffickers to transport the cocaine from Baltimore to New York.

The case resulted in a very successful investigation, the arrest of the traffickers, and the seizure of the cocaine. After Tratados Quimicos, Billy and Ossie went on to work on other successful cases and, in retirement, continue to work together as security manager for Disney Cruise Line.

“That’s $25 million of drugs this subject is sitting on. This is a very high target. When you’re dealing with a source that can talk to someone like that, you have to convince the source that you know what you’re doing and understand how drug traffickers work.”—Retired Agent Ossie DeJesus
