A suspect in the torture-slaying of a U.S. narcotic agent has been extradited to California where he faces federal drug charges, a Drug Enforcement Administration official said Monday.

United Press International reported Tuesday that Leonardo Contreras Subias, 42, who was indicted in April 1980 by a California federal grand jury on drug distribution and conspiracy charges, was arrested on a fugitive warrant April 1 in Salt Lake City.

Subias, also wanted as a possible participant in the kidnap-murder of DEA agent Enrique Camarena, had apparently lived in Utah "off and on for a year," DEA special agent Steve Lough said.

Camarena and his pilot, Alfredo Zavala, were kidnapped near Guadalajara, Mexico, in February 1985, and tortured and murdered. Camarena had been investigating a narcotics ring run by reputed Mexican drug lords Rafael Caro Quintero and Ernesto Fonseca Carrillo, who are both in Mexican prisons in connection with the agent's killing.

The suspect, who maintains he really is Jose Gonzales Guillen and had rented a $650,000 home in Park City, was extradicted Saturday, Lough said.
