Argentina's Supreme Court has ruled that an American who took refuge and started a new life in the South American country can be extradited to face charges that he killed his wife over a decade ago, a court spokeswoman confirmed Saturday.

Kurt Sonnenfeld moved to Argentina in 2003 and sought asylum after prosecutors in Denver charged him with first-degree murder. The decision to extradite him brings to an end a longstanding dispute between the U.S. Justice Department and Argentine courts that centered in part on differences over the death penalty.

In the ruling, which was made Dec. 11, the justices said U.S. prosecutors had assured Argentina that "the death penalty will not be imposed, or if it were ruled, it will not be exercised in this case." The ruling said the executive branch will have final say on an extradition and doesn't specify when it may take place.

Maria Bourdin, a spokeswoman for Argentina's Supreme Court, confirmed the ruling but declined to comment beyond what was in it. Calls to the U.S. Embassy in Buenos Aires on Saturday seeking comment were not immediately returned.

A man who eluded police for 48 days after allegedly shooting to death a state trooper and wounding another is due in court for a preliminary hearing which could decide whether his case goes to county court for trial.

A Pennsylvania district judge must decide Monday whether there are sufficient grounds to send the case against Eric Frein, 31, to county court.

Frein has been charged with shooting Cpl. Bryon Dickson and Trooper Alex Douglass Sept. 12 outside their state police station in northeastern Pennsylvania. He was captured Oct. 30 at an abandoned airplane hangar in the Pocono Mountains.

Authorities say Frein confessed to what he described as an assassination designed to "wake people up" and result in a change in government. Dickson was killed and Douglass was wounded.

Prosecutors are seeking the death penalty. Frein was identified as a suspect shortly after the shootings when a passer-by found his vehicle partially submerged in a small pond near the state police station.

The manhunt, with drew a large police force to the rural area, frightened residents as there were numerous reported sightings of Frein, an expert marksman. A team of federal marshals performing a systematic search stumbled across him about 30 miles from the scene of the shooting and were able to arrest him.
