The woman was killed in a Stockholm flat in August of this year after being stabbed by the 42-year-old more than ten times in the face and upper body.
The Solna District Court said the uncommonly long prison sentence was justified because the victim was killed in an extraordinarily reckless fashion, having likely faced mortal fear and prolonged suffering.
“An unusually tough penalty for a single act. It’s looking quite likely that we’ll appeal,” the man’s attorney, Jonas Granfelt, told the Metro newspaper.
The killing took place following a fight about the woman’s unwillingness to move out of the apartment, despite the couple’s break up.
The 42-year-old claims that he acted in self defence and that the woman had become violent during the altercation.
Immediately following the stabbing, the man poured whiskey over the woman’s dead body and then lay down to sleep next to her for several hours.
When he woke up, he took a taxi to the police station.
In addition to the long prison sentence, the man has also been ordered to pay 150,000 kronor ($20,700) in compensation to the woman’s family.
