Svenska fall S13E10 - Mörkt vatten

Late one October night in 2021, home care workers discover that 97-year-old Julia Feltzin is missing from her apartment in central Örebro. A major search operation is launched and Julia's walker is quickly found next to the dark and very fast-flowing Svartån River that runs through the city. A week later, Julia is found dead in the water. The police investigation leads to the conclusion that she did not end up there voluntarily and the mystery thickens - who is behind the murder and why is a 97-year-old woman being murdered?
