Mexican security forces have arrested Néstor Isidro Pérez Salas, a top assassin for the Sinaloa Cartel, with the U.S. Drug Enforcement Administration offering a $3 million reward for his capture. U.S. President Joe Biden praised the arrest, and Mike Vigil, former chief of international operations for the DEA, called Pérez Salas a "complete psychopath" and a "very dangerous individual". The U.S. is now working to extradite Pérez Salas to face charges in the United States, signaling a major victory in the fight against the Sinaloa Cartel and strong cooperation between the U.S. and Mexico.
