Schürrer had convicted by Västmanland District Court of murdering three-year-old Max and his one-year-old sister Saga, and then attempting to kill the children's mother, 23-year-old Emma Jangestig, at the family's home in Arboga on the evening of March 17th.
Schürrer had been in a relationship with Jangestig's then boyfriend, Torgny Hellgren, and according to prosecutors Frieda Gummesson and Johan Fahlander, her obsession with her ex-boyfriend served as the motive for the killings.
Investigators were never able to tie Schürrer to the crime scene with physical evidence. Instead, prosecutors based their case on strong circumstantial evidence.
Despite the lack of fingerprints or DNA evidence, the court ruled that there was “overall convincing evidence” against Schürrer.
The court determined she had lied about her reasons for visiting Arboga the night of the murders. They also the distressed caused by her break up with Hellgren as a motive for the killings.
The court found Schürrer guilty in late August, at which point it ordered a psychiatric evaluation to determine the appropriate punishment.
She refused to answer questions about the crime, and was ultimately deemed healthy enough to be sentenced to prison.
In addition to receiving a lifetime prison sentence, Schürrer must also pay 457,892 kronor ($64,600) in compensation to Jangestig, as well as a total of 131,329 kronor to other plaintiffs in the case.
Schürrer's attorney Per-Ingvar Ekblad has said previous to the TT news agency that he plans to appeal the district court's decision.
