Joran Van Der Sloot, the man accused of killing Natalee Holloway, could be extradited to the United States from Peru to face criminal charges within the next three months.

Maximo Altez, the Peruvian attorney for Van Der Sloot, confirmed to CNN on Tuesday that the extradition process is already underway.

I think he will be extradited within the next three months, Altez said. He will go to trial in the United States. Once he is sentenced, he will return to Peru to finish serving his 28 years, and then go back to the States to serve whatever sentence he gets there.

Van Der Sloot was convicted and sentenced to 28 years in prison for the murder of Stephany Flores in Peru in 2010. The Dutchman has been the prime suspect in Holloway's disappearance in 2005. Holloway was 18 when she disappeared.

CNN reported that U.S. authorities want to try Van Der Sloot, who has not been charged for Holloway's murder, on extortion and wire fraud charges related to her case.

The Associated Press reported that Van Der Sloot faces extortion charges in Alabama after he allegedly received $25,000 from Holloway's mother in order for him to tell her where to find her daughter's remains.
