The woman was on her way home from work on Sunday evening, December 15 last year, when she was attacked after getting off the bus in Valsta in Märsta north of Stockholm.
The 38-year-old man had sat on the same bus as the woman and followed her when she got off.
Then he assaults her. He had a knife that he stabbed her with, prosecutor Peter Claeson has said to TT.
Randomly selected
The man did not know the woman, who was 28 years old, and she is believed to have been randomly selected.
He himself has said that he wanted to kill a person, Claeson has previously said.
Telling SVT, Claeson now says that the man planned to commit another random murder the next day.
He goes to NK in the city and buys a knife, and then goes to Hallunda to find someone to kill. He sits there for a while but doesn't find a suitable person and goes home. Then the police are there and he can be arrested, he says.
A forensic psychiatric examination has shown that he suffers from a serious mental disorder.
Has been forcibly committed
The man has also previously in life been assessed to suffer from a serious mental disorder and has been subject to forced care on several occasions in recent years. In mid-February 2023, a decision was made to discontinue forced care for the man.
The police found the 38-year-old by tracking his bus card, as they could see on surveillance cameras that he got on the bus at the same time as the woman at Märsta station. He was arrested the very next day and confessed immediately.
When he was arrested, he told the police that they might find something "interesting that wasn't good for him" in his storage room. When the police searched the storage room, they found a bag and the knife where the woman's DNA was later found.
