The Malexander murders were the killings of two Swedish police officers, Robert Karlström and Olle Borén, on a country road near Malexander, Sweden, on 28 May 1999. The killings followed a bank robbery carried out earlier the same day in the town of Kisa, Östergötland. Three men — Tony Olsson, Andreas Axelsson, and former mercenary Jackie Arklöv — were convicted of the crimes. According to the source, all three were active neo-Nazis, and the robberies were intended to raise money to fund a planned "revolutionary" Nazi organization.
At 14:50, Arklöv and Axelsson entered the Östgöta Enskilda Bank in Kisa carrying pistols and grenades and wearing ski masks. They ordered those present to lie down, disabled the security cameras except one black-and-white unit, and emptied the vault, which had a time-limited lock. Olsson stood guard outside with an Uzi. The robbers took approximately 2.6 million Swedish kronor. Kennet Eklund, the only officer on duty at the Kisa police station, was dispatched after an alarm sounded, and at 15:10 the robbers fled in a stolen Saab 9000.
Eklund followed the vehicle until the men pulled over and fired on him; he escaped as grenades were thrown. At 15:18 the three switched from the Saab to a Toyota Avensis. Officers Olle Borén, aged 42, and Robert Karlström, aged 30 — both based in Mjölby — were killed with their own service pistols by shots to the head. The Swedish National Laboratory of Forensic Science reported that Borén was shot five times and Karlström three times.
Axelsson, injured during the shooting, was captured at a medical centre in Boxholm shortly afterward. Arklöv was arrested in Tyresö three days later, having been shot in the lung while evading capture. Olsson left the country and was arrested in Costa Rica on 6 June, when about one million kronor of the stolen money was recovered.
The Linköping court indicted the three men on 26 October. All three received life sentences — Axelsson and Olsson on 18 January and Arklöv on 2 February 2000 — and the sentences were upheld by the Svea Court of Appeal. Olsson and Axelsson admitted the robbery and their presence at Malexander but denied the killings; Arklöv confessed in June 2001 that he alone shot the officers with their own weapons, a version consistent with the forensic findings. The confession did not change the verdicts against the other two. The case was widely debated because Swedish law had no felony-murder rule. Arklöv was later sentenced for war crimes committed in the former Yugoslavia. The life sentences of Olsson and Axelsson were subsequently commuted to 35 years, in 2019 and 2020 respectively.
