The killer, 37-year-old Stefan Nilsson, had previously undergone a psychiatric evaluation and was deemed to have been in a mentally stable condition at the time of the killing.
The District Court ruled on Tuesday ruled that Nilsson should serve prison time for murder and aggravated theft, and that he must pay damages of 200,000 kronor ($30,100) to the relatives of the victim, Jens Janzon.
Nilsson admitted to the killing in August, telling the court that he "choked him until he stopped breathing."
Janzon, 27, was due to go on holiday to Cyprus with a friend shortly before he was reported missing. He was last seen at home in Forshaga, westerb Sweden, with his mother on July 26th. Janzon, who had been in a relationship with Nilsson, was reported missing soon after, and . following a nationwide alert, he was found dead three days later.
The convicted man's lawyer, Lennart Jemtelius, told the Aftonbladet newspaper that he was unsure if he would appeal.
"Even if there was a reason to re-examine the district court's ruling, I don't know if my client can manage another court case about it. He still doesn't feel very well at all," he said.
