DEA agent Kiki Camarena was murdered in Mexico in 1985. His alleged killer is now in the U.S.

DEA agent Enrique "Kiki" Camarena disappeared in 1985, shortly after he helped bust a billion-dollar marijuana operation in Mexico. 

Headed to a luncheon with his wife, Mika, on Feb. 7, 1985, Camarena, then 37 years old, was surrounded by five armed men who threw him into a car and sped away, according to the Drug Enforcement Administration. He had been due to transfer back to the U.S. just three weeks later, the DEA said. 

About a month after he disappeared, his body was found on a ranch about 60 miles away, according to the DEA. He had been tortured.
