Stig Engström (suspected murderer)

Stig Folke Wilhelm Engström (26 February 1934 – 26 June 2000) was a Swedish graphic designer. Long treated by police as an eyewitness to the assassination of Prime Minister Olof Palme, Engström was separately proposed as Palme's assassin by the Swedish writers Lars Larsson and Thomas Pettersson.

Krister Petersson, prosecutor in charge of the investigation, announced the closing of the case at a press conference on 10 June 2020 and stated twenty years after Engström's death, he was the prime suspect in the murder, but that the evidence against him would have been too weak for a trial.

In line with Swedish media reporting practices of not disclosing the names of suspects, Engström was dubbed The Skandia Man (Swedish: Skandiamannen), since he had arrived at the crime scene from the nearby head office of the Skandia Insurance Company, where he worked. Since Petersson's announcement in 2020, Swedish media have referred to Engström by name.
