Who killed an American prosecutor on the tiny Pacific island of Yap? Rachelle Bergeron, 33, was shot to death after going for a run with her dog Monday night on the island, where she served as acting attorney general. Her dog was also fatally shot. While there has been no official comment, it's believed her job could have been the motivation for the murder. Her husband, Simon Hammerling, said that she was at times so fearful for her life that she slept with a machete under her pillow.
