On May 29th 2005, 18 year old Natalee Holloway was enjoying her last night in Aruba with friends on her graduation trip. They had been having a blast the past 4 days and planned on making their last night the best. But when the nightclub they were at started to close, most of her friends went back to the hotel but Natalee wanted to stay out. She was last seen with a local named Joran Van der Sloot and 2 of his friends. To this day there has been no evidence, no body and no official conviction in Natalee's case.
