A German woman sentenced to life for beating to death two young children in Sweden appealed her conviction Friday to the Supreme Court, dpa reported.
Christine Schuerrer has been convicted by two courts, most recently in February, of killing a three-year-old boy and one-year- old girl and seriously injuring their mother in an attack on March 17, 2008.
Her lawyer Per-Ingvar Ekblad said he wanted the Supreme Court to rule on the evidence and the definition of "beyond reasonable doubt," the online edition of the VLT newspaper reported.
The Supreme Court does not automatically grant hearings of all appeals, focusing on cases that set new precedents.
Schuerrer, 32, was convicted without forensic evidence such as DNA or fingerprints linking her to the crime scene in Arboga, central Sweden.
The appeal court last month ruled that Schuerrer had been in Arboga at the time of the crimes and had given a false account of why she had been there. Further, she had had access to a hammer - now missing.
Autopsies suggested the children and their mother, Emma Jangestig, were bludgeoned by a weapon, likely a hammer.
Schuerrer said she went to Arboga to visit an historic site.
Schuerrer was clearly "obsessed" with her former boyfriend, the partner of Jangestig, the appeal court said.
After serving out her sentence, Schuerrer was to be deported to Germany and banned from re-entering Sweden.
Schuerrer was extradited to Sweden at the end of April 2008. More than 50 witnesses were summoned when the district court proceedings opened in July.
