Swedish authorities finally closed a 34-year-old inquiry into the murder of their prime minister.
On February 28, 1986, Swedish Prime Minister Olaf Palme was walking home from the cinema with his family when he was fatally shot in the back. Over the following 34 years, over 10,000 suspects were interviewed. A new team investigated the case in 2017 and concluded that Stig Engström, a now-deceased suspect, was the killer and decided to close the case for good.
