"... Sweden’s judiciary finally made its case on Wednesday. At a news conference in Stockholm, the prosecutor Krister Petersson said that there was 'reasonable evidence'that the assailant was Stig Engstrom, a graphic designer at an insurance company, who killed himself in 2000, at the age of 66....It was hardly a surprise, however, as the Swedish case was widely considered solved in 2018 by a freelance journalist, Thomas Pettersson, whose reporting led to Mr. Engstrom.... There has been widespread criticism about the way the Swedish judiciary and the police have handled the case over the past decades. The mystery endured through six investigations and three commissions over the years, but Mr. Engstrom eluded suspicion though he had presented himself to the police as a witness to the killing.... At the time of the killing, investigators were focused on the suspected complicity of Kurdish militants, and Mr. Engstrom was not taken seriously, according to Mr. Pettersson.... 'He has the right timing, the right clothing; he has unique information, he lied, he had close access to guns of the right type,' Mr. Pettersson said. 'He was right-wing and Palme unfriendly,” he added. “He had a deep political interest and a deep anti-Palme sentiment.'"
