Who killed the prime minister of Sweden? New evidence is expected to answer that question

Palme had been shot in the back from the vicinity of a Stockholm street as he returned from the cinema walking with his wife Lisbeth on a February night. The killer was gone on the streets, and the mystery has engulfed the Swedish police since then, giving voice to speculation theories.

According to one key theory, the killer was alone and could have been committed to prevent Palme's social-democratic policies, while the other includes the apartheid regime in South Africa, writes The Guardian, followed Periscope.

South African intelligence officials have met with Swedish investigators in Pretoria in March and handed over a file with related information.

Whether this file involves solid evidence is unknown.

There have long been speculations about the role of intelligence services of the South African regime, since Palme strongly supported the African National Congress.

The meeting between South African intelligence and Swedish officials took place on March 18th at the request of the latter.

Neither the Swedish side nor the South African have answered The Guardian's questions.

Goran Bjorkdahl, a Swedish diplomat who has independently investigated the murder of Prime Minister Palme, is convinced that the South African apartheid regime was responsible for that murder.

In 2015, Bjorkdahl met with several senior South African intelligence officials in Johannesburg, who named him operatives allegedly involved in the murder of Sweden's prime minister.

“Nevoja to know the truth is greater than the need to punish those responsible,” said Bjorkdahl, after showing that the other side sought immunity for the crime done.

The other theory is that Palme was killed by an individual who ideologically hated his country's social-democratic prime minister. The suspect was Stig Engstrom, known as “Scandia man” because she worked at the Swedish insurance company in offices near the murder scene.

Engstron had ended his life in 2000. According to the Swedish warehouse Filter, Engstrom was the killer, since that was exactly the description of the killer from the witnesses, and had information about the killer, and had lied to the police about his whereabouts on the night of that calamity.

But Bjorkdahl is not convinced of that. He believes Engstrom is blamed because investigators usually give support to the theory that seems simpler. /Periscope
