The U.S. Embassy in Mexico says Sinaloa cartel co-founder Hector "El Guero" Palma will be turned over to Mexican authorities after his release from a U.S. prison.

The U.S. bureau of prisons says Palma will be released Saturday. Palma served five years in a Mexican prison before being extradited to the United States, where he was sentenced to 16 years for transporting 50 kilograms of cocaine.

It is unclear whether Palma still faces any charges in Mexico.

Attorney General Arely Gomez says prosecutors are looking through files for any remaining criminal cases. She said that in some cases the statute of limitations has expired.

Palma was arrested June 23, 1995 in western Mexico.

The embassy said Thursday that "the United States and Mexico enjoy strong cooperation in security."
