Vilma Andersson, 26, the suspect in the Rönninge dismemberment murder, has been deemed free of serious mental disorder and suitable for prison following a forensic psychiatric investigation. Diagnosed with antisocial personality disorder, he expressed dissatisfaction, having hoped for psychiatric care.
A forensic psychiatric investigation by the National Board of Forensic Medicine in Huddinge, lasting over six weeks, concluded on Tuesday that Vilma Andersson does not suffer from a serious mental disorder under legal definitions, making him suitable for prison rather than care. A source told Expressen: "He was very dissatisfied – he had set his sights on getting care."
Andersson, arrested in December 2025 near Rönninge station while handling remains of the 25-year-old victim who disappeared on Christmas Eve, faces charges of murder and grave desecration (which he has admitted but denied murder). He has prior convictions, including attempted kidnapping of a child and child pornography offenses.
The investigation highlighted his antisocial personality disorder, characterized by manipulative and impulsive behavior, lack of remorse, and empathy deficits. While at Huddinge, he was housed in a private ward with amenities due to security concerns. On Wednesday, he was transferred to a standard detention facility ahead of trial. Prosecutor Markus Hankkio indicated potential further mental health probes post-trial regarding the crime timeframe.
