US prosecutors won't seek the death penalty for Mexican drug lords Zambada and Caro Quintero.

US prosecutors will not seek the death penalty for Mexican drug lords Ismael "El Mayo" Zambada and Rafael Caro Quintero, who are charged with drug trafficking and the 1985 killing of a US DEA agent. Both have pleaded not guilty, and it is unclear if this decision signals the possibility of a plea deal. Their cases are being heard in the same Brooklyn federal courthouse where Joaquín "El Chapo" Guzmán was tried and convicted.
