Five years after he was the prime suspect in the murder of Natalee Holloway, Dutch national Joran Van der Sloot is back under police scrutiny. This time, it's because he is the prime suspect in the murder Stephany Flores Ramirez, a 21-year-old from Peru who disappeared Friday and was found dead in a hotel room Wednesday. Van der Sloot, now 22, was originally arrested for Holloway's murder in May 2005 and released. He was then charged with manslaughter in November 2007 and was again set free.
