Senior Field Correspondent Michel Marizco (Tucson) has reported along the Southwest border for the past decade, most of that in Arizona and Sonora. Before joining the Fronteras Desk, he produced stories in the field for CNN Madrid, the BBC, 60 Minutes Australia, and the CBC. His work now focuses on transnational trafficking syndicates, immigration, federal law enforcement and those weird, wild stories that make the U.S.-Mexico border such an inherently fascinating region. He is a contributing author on Shared Responsibility: U.S.-Mexico Policy Options for Confronting Organized Crime and an occasional writer at High Country News. In his spare time, he works with Investigative Reporters and Editors and the Dart Center for Journalism and Trauma, assisting in the ongoing investigations of journalist killings in Mexico.
