In an interview Tuesday on ABC's "Good Morning America" Dave Holloway of Meridian, Miss., said, "He confessed to this one ... I would like for him to tell everyone what happened." He added, "Hopefully this is his last victim."
Police in Lima said late Monday that Van der Sloot admitted killing 21-year-old Stephany Flores.
He has been the main suspect in the disappearance of Holloway five years ago on a class trip to Aruba, and is charged with trying to extort $250,000 from her family in exchange for information about the case.
