Serafin Zambada, son of Sinaloa cartel leader, pleads guilty to drug charges in US

The son of one of the world's most wanted drug lords has pleaded guilty to drug trafficking charges in San Diego.

Serafin Zambada admitted Friday that he conspired to bring more than 100 kilograms of cocaine and 1,000 kilograms of marijuana from Mexico to the United States. The 24-year-old son of Ismael "El Mayo" Zambada faces a minimum punishment of 10 years in prison and a maximum of life when he is sentenced May 22.

The younger Zambada was arrested last year at a border crossing in Nogales, Arizona. His attorney said the San Diego-born man was on his way to Phoenix for an appointment with U.S. immigration authorities to arrange legal status for his wife.

The elder Zambada is a leader of Mexico's Sinaloa cartel.
