Overview

Case overview

Swedish Prime Minister Olof Palme was shot at close range while walking home from a Stockholm cinema with his wife, Lisbet, on 28 February 1986. The attacker fled through nearby streets before police could identify or detain him. [1]

The investigation became one of the largest in Swedish history. In 2020, prosecutors named the deceased Stig Engström as their suspected offender and closed the case, but the allegation was never tested in court. [2]
