More than 30 years later and the assassination of the Swedish Prime Minister Olof Palme, a new suspect emerges.
The result of a 12-year investigation by reporter Göran Bodin published on Wednesday suggests there is now a suspect with motive, access to the murder weapon and opportunity. The name of the suspect has not been published.
According to Filter magazine, Sweden may have the answer to the question of who killed the prime minister on the 28th of February, 1986. He was gunned down as he was walking with his wife from a night out in the cinema, in a murder that changed security culture in Sweden.
The gunman ran off with the murder weapon and despite questioning more than 10,000 people and 134 individuals coming forward to claim responsibility, the murderer has yet to be apprehended.
