The two teenage girls were found guilty of aggravated robbery and were given 18 month sentences in juvenile detention.
The court heard how the girls in the autumn of 2013 decided to lure men into a trap for money through an online dating agency. "They arranged to meet men who wanted to buy sex off them and received pre-payment but then found an excuse to leave without performing sex," the Solna District Court wrote in a press release.
The murder happened on 5 September 2013. As in previous robberies, the girls made an online appointment to meet at Järva restaurant in Solna and walked with the victim, a 32-year-old man, to a cash mashine before leaving for a wooded area where their male companions were waiting.
"A scuffle occurred between the three men and in the altercation, one of the girls took SEK 5,500 in cash from the victim," the district court found. The men denied repeatedly stabbing the victim but admitted that they took part in a fight with the man, and they robbed him.
Despite the men's denials, the Court considered that there was evidence that one of them had killed the victim by stabbing him 18 times with a knife. One of the two girls denied the offence, while the second confessed.
According to the prosecutor Jenny Clemedtson, the crime involved money and nothing else. Damages of SEK 118,000 were ordered to be paid to the victim's relatives.
