Officials say 46-year-old Paul Eischeid, a Hell's Angels member, has been extradited back to the United States and is in the Maricopa County Jail after fleeing custody 15 years ago.
According to the United States Marshals Service, Eischeid was arrested in 2013 after he was indicted for drug trafficking and RICO violations. His charges included kidnapping and homicide in connection to the brutal 2001 murder of Cynthia Garcia.
Garcia, officials said, was "severely beaten, thrown in the trunk of a car, taken to the desert, stabbed 27 times and was partially decapitated."
Eischeid, officials said, was released in 2003 "on his own recognizance," with electronic monitoring, but he cut off his monitoring bracelet and fled the country.
U.S. Marshals said Eischeid obtained a new identity with a fake passport and even changed his appearance while on the run. He was added to the "15 Most Wanted" list in 2007.
Eischeid was arrested has been in the custody of Argentinean authorities since being arrested in the country in 2011, according to officials.
According to U.S. Marshals, Eischeid had been fighting extradition for the past seven years. In June, U.S. Marshals learned from the Argentinian government that Eischeid had "exhausted all of his appeals in the Argentinian government legal system."
Eischeid returned to Arizona Tuesday and was booking for first-degree murder and kidnapping.
