Convicted killer Joran van der Sloot reportedly says he will fight extradition from Peru to the United States in connection with the disappearance of American Natalee Holloway in Aruba.
Van der Sloot remains the prime suspect in the unsolved 2005 disappearance of Holloway in Aruba.
He is currently imprisoned in Peru, serving time for murder.
He was sentenced in January after confessing to beating and strangling 21-year-old Stephany Flores in his hotel room.
If he remains behind bars in Peru, Van der Sloot could be released on parole after serving a third of his 28-year sentence for killing Flores, a Lima woman he met at a casino in May 2010.
If he were convicted in the US, however, he would be unlikely to qualify for early parole in Peru.
Under the US-Peru extradition treaty he would be returned to Peru to finish his sentence. Then he would be sent to the US to serve the second sentence there.
