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."
