WASHINGTON (AP) — Ismael “El Mayo” Zambada, a historic leader of Mexico’s Sinaloa cartel, and Joaquín Guzmán López, a son of another infamous cartel leader, were arrested by U.S. authorities in Texas, the U.S. Justice Department said Thursday. A leader of the powerful Sinaloa cartel for decades alongside Joaquín “El Chapo” Guzmán, Zambada was known for running the cartel’s smuggling operations, but keeping a lower profile. The U.S. Drug Enforcement Administration had offered a reward of up to $15 million for information leading to his capture.
