After undergoing psychiatric analysis the man was declared to be unaffected by any psychiatric illnesses, according to the TT news agency.
The man claimed in court that it “must have been someone else” who took his girlfriend’s life, as he was rendered unconcious shortly before the incident occurred.
He explained that there was a knock at the door, and that the woman went to open it. Then, the man claims he lost consciousness and didn’t wake until the arrival of the police.
However, the Ystad District Court believed that the man had deliberately strangled his girlfriend.
The man’s teenage daughter, who was in the apartment with her own one-year-old child at the time of the murder, had explained earlier that her father had tried to strangle his partner on another occasion.
The daughter also made a number of emergency text messages to her mother and her brother immediately before the murder, stating that her father was abusing his girlfriend.
The murder may have been triggered by the fact that the woman had planned to leave the man and move elsewhere.
The man was also sentenced to pay 160,000 kronor ($23,671) in damages to the family of the victim.
