Autopsy results show that an American tourist killed with a sword at a resort in the island nation of Grenada was also raped and choked. Jessica Colker, 39, suffered an “extensive” skull fracture, officials said. Colker, originally from Georgia, was attacked Sunday while strolling on the beach with her husband, and he was able to escape uninjured. Colker’s body was found about an hour later with machete wounds, among other injuries. A person of interest has been questioned but not charged in the crime.
