Picture of the grave of former Swedish P

Stockholm, SWEDEN: Picture of the grave of former Swedish Prime Minister Olof Palme, taken 04 February 2006, just a few blocks away from the place where he was assassinated, 28 February 1986, in Stockholm. Two decades after Palme was gunned down on a wintery February night on a Stockholm sidewalk, the trails to his assassin have gone cold, but Swedes hope that he will one day be found. Shortly after leaving a Stockholm downtown cinema to walk home with his wife Lisbet, he was shot twice in the back by a lone gunman. The man ran off, leaving Palme, who had been without bodyguards, to die in a puddle of blood, and taking with him the murder weapon, which has never been recovered.
