Lawyer Fredrik Lindberg added that he will press for a comprehensive psychiatric examination at the remand hearing.
“There have been reports saying that he may have a serious mental disorder,” said Lindberg. “He has no official diagnosis, but it is possible that he suffers from Asperger’s syndrome.”
Lindberg did not go into detail about the origin of the information on the possible link to a mental disorder.
Asperger’s syndrome is a diagnosis in psychiatry and an autism spectrum disorder. Those with Asperger’s display significant difficulties in social interaction, along with restricted and repetitive patterns of behavior and interests.
The man’s 12-year-old half-sister, 15-year-old half-brother and their 49-year-old father were murdered with an axe in Härnösand, 400 kilometres north of Stockholm. Their bodies were found early on Tuesday evening at the house where the two younger children lived with their mother and her new partner.
Two other people initially arrested in connection with the killings – the man’s 63-year-old father and the 62-year-old partner of the murdered children’s mother – were released without charge.
Lindberg disagreed with police that his client planned the attack against his half-siblings and their father.
“He has had something in mind for a long time, but what he meant and what he meant to do is not clear,” said Lindberg.
What motivated the man to kill his three family members is not clear, he said.
“It is still shrouded in mystery,” said Lindberg.
The suspect was remanded in custody on Friday and a remand hearing was held at the Ångermanland District Court in Härnösand at 1pm. When the remand hearing began, the suspect admitted the charges of murder through his lawyer and did not contest the application to remand him. After a brief introduction, the hearing continued behind closed doors.
“I will probably insist on it for the sake of the investigation,” said deputy chief prosector Bertil Månsson. “The man has indeed admitted to the crime, but there are a lot of things we will want to hear about him later on, especially about the motivation behind the crime, I can imagine.”
In the remand petition, Månsson wrote that the man is suspected on probable grounds of murder in Härnösand on May 11th.
The man has provided DNA samples to the police. The sample will then be compared with DNA traces from unsolved criminal investigations in Sweden, including a double murder in Brattås outside Härnösand in May 2005.
“Since there are DNA traces from Brattås, we will check them against this man’s DNA,” said Börje Öhman, information officer of the Västernorrland police authority.
In the Brattås murder, a 70-year-old man and a 57-year-old woman were killed.
The police expect results from the DNA test for the Brattås case at the earliest on Tuesday, but probably at the end of next week.
