Mexico has sent drug lord Rafael Caro Quintero, who is wanted for the notorious killing of a U.S. DEA agent in 1985, to the United States with 28 other prisoners requested by the U.S. government, the Justice Department confirmed Thursday evening.

Mexico on Thursday sent the United States 29 people accused by American authorities of being drug cartel members, the two governments said.

Those extradited reportedly include Rafael Caro Quintero, long sought in the killing of a U.S. narcotics agent.
