Matija Sovdat

years_active = employer = organization = agent = known_for = criminal_charge = conviction_penalty = Forensic psychiatric care conviction_status = Gradual release from 2000, and Sovdat himself was sentenced to two weeks in prison, his first conviction for a violent crime. He later told the district court that something inside him had snapped.

At the same time, family members, friends, and police sources described Sovdat as a person with a contradictory personality. He could be perceived as intelligent, determined, and charming, but also as dominant, violent, and struggling with drug abuse. A former girlfriend described him as "Dr. Jekyll and Mr. Hyde," stating that many people were afraid of him, while he could at the same time be very polite toward women. The police noted the same duality and stated that he could quickly shift into violent outbursts of rage if he felt threatened or insulted. in his home at Byälvsvägen 169 in Bagarmossen. He was found dead by social services on the morning of 26 July 1996 and was assessed to have been deceased for a considerable period of time, likely several weeks. Initially, the police reported that Karlsson had been killed by stabbing, and at first a murder during a robbery was suspected.

Initial investigation

The police initially found no traces of the perpetrator and had not been able to contact any witnesses who had observed anything related to the murder. On 27 July 1996, the police conducted door-to-door inquiries in the area in the hope that neighbors had seen or heard something. Bengt Wingqvist, head of investigations at the Stockholm County Criminal Police (länskriminalen i Stockholm), confirmed that the man had been killed but declined to comment on the method used.

Second murder David Eklund (22) and Harriet Illerström (21) were murdered on 1 May 1998 at Flyghamnsgatan 11 in Skarpnäcks gård. In the same act of violence, the couple's dog, a Cavalier King Charles Spaniel named Sussie, was also killed. The murders were carried out with extreme brutality. The perpetrator used five different weapons—two knives, a hammer, a crowbar, and a club. David and Harriet suffered more than 200 injuries between them, and Harriet’s eyes had been cut out. After murdering the couple, the perpetrator moved the bodies to the bathroom, where he placed them on top of each other in a cross formation.

The crime scene showed clear signs of struggle and defense from the victims. The autopsy revealed that David had been subjected to about 50 cuts and blows, while Harriet had significantly more injuries than the perpetrator later admitted in interrogations. The couple had just returned from a birthday celebration and had spent the Walpurgis Night weekend in the apartment, but two days later, on Sunday, their bodies were discovered by Harriet's older sister, who had come to visit. On Walpurgis Night, the couple had hosted a party, and the police interviewed several people who had been in the apartment during the evening. Everything indicated that the murders had been preceded by some form of struggle. On 4 May, the Söderort Police (Söderortspolisen) opened a tip line to receive information from the public. A forensic investigation was carried out on Monday, 4 May, and on Tuesday the bodies were autopsied. About twenty police officers worked on the case, which was described as ruthless and exceptionally brutal. The police suspected that Harriet had tried to help David escape his attacker and noted that she had several typical defensive injuries. Five people who had been in the apartment on Walpurgis Night were questioned, and several pieces of evidence were secured—including fingerprints on weapons, a jacket, and a bicycle that could possibly be linked to the perpetrator.

On 6 May 1998, Matija Sovdat was arrested at his mother's home at 82 Svartågatan in Bagarmossen, At the time of his arrest, he was heavily under the influence of Rohypnol and alcohol. He had abused Rohypnol for an extended period and had memory gaps regarding what had happened. The police secured, among other things, Sovdat's fingerprints at the crime scene, as well as bloodstained clothing and a bloodstained knife in his residence and in a garbage bin. On 9 May, Sovdat was remanded in custody on probable cause, suspected of the double murder, by the on-call court of the Stockholm District Court.

On 24 June, it was decided at the remand review hearing that Sovdat would undergo a forensic psychiatric examination (Rättspsykiatrisk undersökning, RPU). A few weeks earlier, he had confessed to the murders. Sovdat, who was acquainted with David, was unable during questioning to provide a clear motive, but hinted that he was jealous of David's relationship with Harriet.

Memory researcher Sven Å. Christianson was involved in the interrogations of Sovdat in an attempt to get him to talk.

Suspicions of additional murders On 22 July 1998, while Sovdat was undergoing a forensic psychiatric examination, the police announced that they had new murder suspicions against him. The police reviewed, among other cases:

The murder of 25-year-old KTH student Per Häggström at on 99, Stockholm, on 14 October 1996. The , a receptionist at in Visby, on 12 December 1996. The murder of 61-year-old Jewish antique dealer Dan Barak on , Stockholm, on the night of 5–6 July 1995. The murder of 59-year-old teacher Åke Sterner at 153 on Södermalm, Stockholm, on 1 September 1994. In this case, in May 2003, the then 28-year-old Nazi (later Lindberg) was sentenced to six years in prison for manslaughter. The in Hammarbyhamnen, Stockholm, on the night of 31 December 1994–1 January 1995.

A common factor in several of these cases was extreme violence, sometimes directed at the victims' eyes—a so-called killer signature—indicating the same perpetrator.

On 21 July 1998, a special task force was formed with representatives from the Söderort Police, the City Police violent crimes unit, and the National Criminal Police's Investigation Department to analyze technical evidence and the offender profile. Psychiatrist and a forensic pathologist participated, along with five police officers.

Further investigation Sovdat was held in a secure forensic psychiatric unit in Gothenburg, where experts from the National Board of Forensic Medicine examined his actions and mental condition. The assessment included medical records, police investigations, social service reports, and school transcripts in order to determine whether he suffered from a severe mental disorder. Had that been the case, Sovdat would have faced compulsory forensic psychiatric care. The police reported that Sovdat would probably be ruled out as a suspect in at least four of the eight murders he had been suspected of, including the murder on Valhallavägen, following technical analysis and voice analysis of a call to the emergency number SOS Alarm.

In mid-August 1998, it was reported that Sovdat would be charged in mid-September 1998 at the Stockholm District Court for the double murder in Skarpnäcks gård and the murder in Bagarmossen, which he had confessed to and in which bloody traces from the victims' homes had been linked to him through shoes and clothing. Other investigations, such as the murder of the receptionist in Visby and the older cases in Stockholm, were ongoing, but Sovdat was not considered a particularly likely perpetrator in these cases.

Trial and verdict The trial was held at Stockholm District Court between October and December 1998.

On 7 October 1998, Sovdat was indicted on three counts of murder. He was also of interest in the continued investigation of an additional murder. After confessing to the crimes, Sovdat had provided an explanation that the police did not consider credible. Instead, investigators assessed the acts as pure lust murders. One circumstance that, according to the police, strengthened the suspicions against him was the icy coldness he displayed. As an example, they stated that after the murder of the elderly Karlsson, he had remained in Karlsson’s apartment watching television until nightfall, allowing him to leave the scene without being seen.

On the first day of the trial, 12 October 1998, Sovdat stated that Karlsson had offered him illicitly distilled alcohol in the apartment. According to Sovdat, Karlsson demanded sexual services as payment. Sovdat said that he then struck Karlsson in the face and subsequently used extremely excessive violence, something that also characterized the double murder in Skarpnäcks gård. In earlier police interrogations, Sovdat had said that he was under the influence of amphetamines at the time of Karlsson's murder, but he withdrew this statement before the court. He stated that he had been sober and explained that he had previously had difficulty recounting events without making excuses. Sovdat described how he covered Karlsson's body with furniture and debris and then remained in the apartment for five to six hours watching television while waiting for darkness to fall.

The police interrogations presented a contradictory picture of Sovdat. On the one hand, he had been in a steady relationship for nearly six years, had begun studies at the Stockholm Institute of Education, and was described as highly articulate. On the other hand, he had abused primarily Rohypnol in combination with alcohol, as well as cannabis, amphetamines, and LSD. He moved within rave circles and often frequented the techno club . Mental illness occurred within his family. A forensic psychiatric examination conducted in late summer showed that Sovdat did not suffer from any severe mental disorder. Sovdat subsequently requested that the Legal Council of the National Board of Health and Welfare (Socialstyrelsens rättsliga råd) issue an opinion, but no position had yet been taken. According to his defense attorney, Jan Karlsson, Sovdat preferred to be sentenced to psychiatric care rather than imprisonment.

On 14 October 1998, the National Board of Health and Welfare decided that its Scientific Council would meet with Sovdat to assess his mental condition, preliminarily in late November 1998. Only thereafter would the district court proceedings be concluded and a verdict delivered. When Sovdat recounted his version of the murders, he showed no emotion. When he described pulling a knife out of Harriet's eye, his voice did not tremble. He said that the couple had been decent and pleasant and that he had liked them, but that he could not understand how everything had developed in this way. In police interrogations, Sovdat had claimed that he had not felt any sexual desire in connection with the killings, despite semen having been found in his bloodstained trousers left in the apartment. David's and Harriet's families demanded financial compensation from Sovdat and that he pay for the couple's funerals. Among those seeking damages were several children who were half-siblings and step-siblings of the victims. The families had suffered greatly after the murders, and on the Tuesday an immediate family member had been admitted for treatment at a psychiatric clinic.

On 18 December 1998, Sovdat was convicted of murder, drug offenses, and violations of the knife act and sentenced to institutional psychiatric care with special discharge review. The special discharge review meant that it was the administrative court that would decide when Sovdat was considered sufficiently recovered to be released. In this assessment, his treating physician participated and, in cases of such serious criminality as this, the prosecutor as well. The most recent forensic psychiatric assessment was carried out by Gunnar Kullgren, who stated in his opinion to the Stockholm District Court that Sovdat would be in need of care for a very long time.

Aftermath

Judgment, treatment, and gradual release On 18 December 1998, Sovdat was sentenced by the Stockholm District Court to institutional psychiatric care with special discharge review for three murders. The judgment emphasized the extreme seriousness of the crimes and the significant risk of reoffending. Professor of forensic psychiatry Gunnar Kullgren stated that "it perhaps hardly needs to be pointed out that the 28-year-old will require a very long period of treatment." The court also noted that the mental disorder was of such a nature that the risk of renewed serious violent criminality could not be ruled out. A recurring justification was that Sovdat was considered stable within the treatment environment and that he had formally complied with the conditions of his leaves, which gradually formed the basis for increasingly long and extensive freedoms.

The case exposed a gap in the legislation: interns within schools and youth recreation services were not subject to mandatory criminal record checks. This was criticized by both the National Agency for Education and the Swedish Association of Local Authorities (Svenska Kommunförbundet), who argued that responsibility was unclear and that the system did not sufficiently take children's safety into account. Relatives openly questioned who would bear responsibility should Sovdat reoffend in violent crime. He criticized the way forensic psychiatry assessed dangerousness, pointing out that such evaluations were conducted in a controlled environment without drugs, despite Sovdat's documented abuse of substances including Rohypnol, amphetamines, and cannabis.

Strindlund called for legislative changes, arguing that individuals assessed as extremely dangerous should not be eligible for release from forensic psychiatric care but should instead serve the remainder of their time in prison if they were deemed "healthy." His criticism was shared by several police officers involved in the investigation, who described the situation as irresponsible and dangerous.

On 31 August 2005, a serious incident occurred during a leave. Sovdat, with a blood alcohol level of over 0.2% and under the influence of benzodiazepines, drove into a pole. He also threatened a security guard with death.

For the victims' relatives, this represented the culmination of a long-standing crisis of confidence. They described a life marked by fear and the experience that the legal system and forensic psychiatric care had failed to adequately account for the severity of the crimes and the perspective of the victims. Several reported that they had relocated or lived in hiding and that they had completely lost faith in the authorities' ability to protect the public.
