As noted below, the French police and the FBI are now treating the disappearance of Bison Dele and his girlfriend as a murder investigation, with the focus being on his brother, who was detained shortly after they went missing on an identity theft charge, then released. Dele's catamaran was found late last week, and according to one tip, investigators are looking into a possible fight on board that led to the murders. The more I find out about Dele, the sadder this story gets.
