Aftonbladet's investigation reveals that at least 38 percent of men who killed a partner between 2000 and 2024 were under the influence of alcohol or drugs at the time of the crime. The case of convicted murderer Magnus illustrates the strong link between substance abuse and violence against women. Experts emphasize the need for better rehabilitation to reduce recidivism risks.
For decades, convicted murderer Magnus has terrorized women, often under the influence of alcohol. At age 29, he was sentenced for killing his ex-girlfriend Emma and has since been convicted or reported for other instances of violence against women. According to witness statements and documents, Magnus has had harmful alcohol use since his teens, seen as a major risk factor for his violent crimes. Despite this, he still drinks, per witness accounts obtained by Aftonbladet.
Aftonbladet's review of cases where men killed women between 2000 and 2024 shows that at least 38 percent were under the influence of alcohol or drugs at the time of the act. Many of these men had long-term, documented substance abuse issues. Addiction researcher Fred Nyberg, professor at Uppsala University, explains: "Alcohol can amplify the propensity for violence and reckless behavior." He highlights the strong link between intimate partner violence and addiction, warning that society focuses too little on rehabilitation due to fears of stigmatization.
Research indicates that many violent offenders have psychiatric diagnoses combined with substance abuse. Magnus has a borderline diagnosis, featuring mood swings and fear of abandonment. Nyberg adds: "Drugs can trigger aggressive behavior, but it often involves comorbidity—substance abuse combined with mental health issues." Sobriety improves impulse control and reduces violence, he states.
Ellinor Hallebro, a specialist at the Swedish Prison and Probation Service, stresses that substance abuse should always be investigated in intimate partner violence cases. Among convicts with medium to high risk of recidivism, 68 percent need interventions for alcohol abuse. "It can involve effects on self-control, strategies for handling difficult emotions, and it can be used as an excuse," she says. The Prison and Probation Service collaborates with healthcare and municipalities but cannot force abstinence. Nyberg calls for better preparation for life outside prison, including meaningful employment, to break the cycle of addiction and crime.
