This study analyzes the demographics, criminality, and network relations of forty-one deceased Swedish foreign fighters. Our results show that most of the deceased Swedish foreign fighters were on average just under 26 years old when they died. Concerning network relations, nineteen out of the forty-one foreign fighters had at least one relationship (next-of-kin or friend) with another deceased foreign fighter. Two thirds were previously suspected of at least one crime. Based on our results, we argue that more attention needs to be given to tertiary and secondary prevention directed toward foreign fighter hubs.
