Drug Enforcement Administration

The Drug Enforcement Administration says since April drug agents also seized 134,000 doses of illegal steroids, more than 1,300 pounds of raw steroid powder, nearly 2,100 gallons of raw steroid liquid and more than $2 million in cash. 

Agents from the Department of Homeland Security and the U.S. Postal Inspection Service were also part of the agency's "Operation Cyber Juice."

The five-month operation concluded with nine arrests Tuesday.

DEA's deputy administrator Jack Riley said Thursday that the last week has been a flurry of work speaking with his Mexican counterparts and helping direct U.S. efforts to capture one of the world's most prolific and violent drug lords for the third time in 15 years.

"This guy caused me one of the best days and worst days of my life in a span of a year," Riley told The Associated Press. "We are doing everything we can to track him down, much like we did a year or so ago when we hooked him."

The internal DEA documents reveal that drug agents first got information on escape plans in March 2014, about a month after Guzman was captured in the seaside resort town of Mazatlan, Mexico.

Immediately after Guzman's arrest, which was considered a crowning achievement of Mexican President Enrique Pena Nieto's government in its war against drug cartels, various Guzman family members and drug-world associates were considering "potential operations to free Guzman," the documents show.
