A phone operator in Hamarøy in the north of the country was the first to realize that Feste was in distress after the 98-year-old set off her emergency medical alarm.
Since the alarm allows for two-way communication, the operator heard what was happening in the apartment, newspaper Bergens Tidende reports.
According to alarm operator service HT Safe, and officials from Os council, the operator placed a call to the town’s home-care service after failing to establish verbal contact with Feste.
The home-care nurse on duty in the building next door to the Feste’s was then sent to the woman’s apartment at the Oshaugen care facility.
When the care worker looked through the window and saw the woman being attacked, she retreated to a safe location and notified the police.
The nurse then phoned two of her colleagues who were working nearby. Together, the three of them entered Feste’s apartment, where they found the 98-year-old woman in a shocking condition.
Prosecution lawyer Asbjørn Onarheim has refused to either confirm or deny that Feste had been sexually abused.
A preliminary post mortem report has shown that Feste died from massive head injuries.
Police have not made any arrests.
“We’re facing a murder case with an unknown culprit,” said Onarheim.
