Joran van der Sloot, the 22-year-old Dutchman who has long been a suspect in the killing of Natalie Holloway in Aruba, was arrested in Chile on Thursday for the murder of a young woman in Peru. Stephany Flores, 21, was found dead in a Lima hotel on Sunday, exactly five years to the day Holloway disappeared. Police say that van der Sloot was seen with Flores before she was killed on Sunday.
