Early arrests By coincidence, Bengt Hjalmarsson was arrested by the Malmö
Police Authority for a separate crime on the afternoon of 8 January 1980, two months after the murder. Hjalmarsson's mother had reported her son to the
Helsingborg police regarding a burglary that occurred in her house on Bogesundgatan in
Ramlösa on Christmas Eve 1979. Hjalmarsson had stolen valuable books, an older
mortar and pestle and
flint axes. Due to Hjalmarsson's uncooperative nature during the arrest, the police obtained a
search warrant to his apartment on Kornettsgatan on 9 January. During their initial search of the apartment, police found it "cluttered" with
boxes stacked on top of each other. In addition to Hjalmarsson's mother's belongings, the police also found roughly 400 books belonging to the
Malmö City Library worth over 100,000
Swedish kronor. Hjalmarsson spent two nights in the police station's
jail cell, but was released on the afternoon of 10 January due to a lack of reason to keep him
detained over his crimes. On 10 November 1979, Katarina Jakobsson's parents reported her missing to the Malmö Police as she had not met Nilsson or their son, which was scheduled to have occurred on 8 November. Police officers visited her Almbacksgatan apartment for routine checkups in both November and December 1979. During both visits, the responding officers noticed subtle changes, such as a changed door lock, that suggested Jakobsson was still alive. Together with the help of a
locksmith and Jakobsson's father, the police
forcibly entered her apartment once more on 16 January 1980, upon which they discovered Hjalmarsson hiding in the bedroom closet. When several paper notes in Hjalmarsson's apartment were analyzed, the police found a
train ticket which linked him to the burglary of his mother's house, alongside several
postcards referencing Jakobsson and her pension, which Hjalmarsson had claimed. Bengt Hjalmarsson's trial started on 18 June 1980, where he was represented by
criminal defense lawyer Börje Svedberg, who, due to a
certification issued by a psychiatric doctor, requested that "Hjalmarsson did not need to be present during the rest of his own hearing", as there was a "serious risk Hjalmarsson would become
aggressive" or suffer from other mental issues if he were to be interrogated in court. Although
Prosecutor Ragnar Emanuelsson argued against this, Judge Ivar Adell relented and transferred Hjalmarsson back to his psychiatric care for the remainder of his hearing as "Hjalmarsson did not verbally respond to anybody in court". The rest of the
trial in absentia lasted roughly five hours, during which both the prosecutors and Svedberg argued for
psychiatric care as a penalty. On 25 June 1980, the
final verdict was announced; Hjalmarsson was sentenced to indefinitive closed psychiatric care at St. Lars hospital. Hjalmarsson did not
appeal his sentence. == Perpetrator ==
