Convicted serial killer Peter Mangs has appealed his lifetime sentence, lawyer Jesper Montan told the Sydsvenskan newspaper.
“The final decision for filing the appeal was made over the weekend,” said Montan.
Mangs was sentenced to life in prison by a unanimous district court last month over two murders and five attempted murders.
Montan now hopes for an acquittal by the Court of Appeal and believes the chances are relatively good.
The prosecutors have yet to make a decision about a potential appeal.
Mangs, who targeted immigrants, was also ordered to pay damages to his victims of SEK 1,175,000.
His sentencing was delayed by an investigation into his mental health, and then by accusations that one of the judges had a conflict of interest.
The court said that his crimes were characterized by "extreme ruthlessness, and a lack of empathy".
