Joran Van Der Sloot, the main suspect in the Natalee Holloway disappearance, has challenged his extradition to the United States by indicating he wants to remain in Peru and serve his 28-year murder sentence there.

Van Der Sloot's Peruvian attorney Maximo Altez confirmed to CNN Wednesday that the Dutchman stated his preference to a judge and prosecutor on Tuesday. He is wanted in the U.S. to face charges in Holloway's disappearance.

24-year-old Van Der Sloot is serving a 28-year prison sentence for murdering Stephany Flores in Peru in 2010. Flores was a woman he met Flores at a Lima casino.  

Van Der Sloot is accused of extortion in Alabama for allegedly receiving $25,000 from Holloway's mother in exchange for him telling her where she could find the remains of her 18-year-old daughter. Holloway's body has never been found.

Van Der Sloot has never been charged for Holloway's 2005 disappearance.

Altez told CNN that should Van Der Sloot be convicted in the U.S., it could affect his chances of parole in Peru. He added that Van Der Sloot will likely be extradited regardless of his preference. This is because there is a long-standing extradition treaty between the two countries.
