According to the Hela Gotland newspaper the Swedish National Board of Forensic Medicine has ruled that the man was so disturbed at the time of his attack he had lost the ability to understand the consequences of his actions, and has as a result recommended that he be given psychiatric treatment rather than a prison term.

The agency said that Engström had still been disturbed at the time he was given psychiatric assessment, and warned that there was a risk that Engström would commit further criminal acts. 

“This is a question which has relevance at a future stage,” said prosecutor Henrik Olin. “It means he cannot be sentenced to jail, but will instead receive psychiatric care. But it is not going to change how the investigation is carried out.”

Engström stabbed Wieselgren, who worked as psychiatric coordinator for the Swedish Association of Local Authorities and Regions, as she was on the way to take part on a discussion at the Almedalen political festival. She died in hospital later that day. 

Engström has admitted to carrying out the attack, telling police that he intended to make a protest against the state of psychiatric healthcare in Sweden.
