On Friday, 28 February 1986, at 23:21 CET (22:21 UTC), Olof Palme, Prime Minister of Sweden, was fatally wounded by a single gunshot while walking home from a cinema with his wife Lisbeth Palme on the central Stockholm street Sveavägen. Lisbeth Palme was slightly wounded by a second shot. The couple did not have bodyguards with them.
Christer Pettersson, who had previously been convicted of manslaughter, was convicted of the murder in 1988 after having been identified as the killer by Mrs Palme. However, on appeal to Svea Court of Appeal, he was acquitted. A petition for a new trial, filed by the prosecutor, was denied by the Supreme Court of Sweden. Pettersson died on 29 September 2004, legally declared not guilty of the Palme assassination.
