In an interview with Aftenposten he describes his continual fear of Gjert during his upbringing and various episodes where Gjert for example choked him or Henrik, punched him, poured cold water on 3 year old Ingrid when she got night terrors. In other words, Gjert’s actions were not limited to berating, but included physical abuse. He says the children walked on eggshells around Gjert and never knew what kind of mood he was in. Due to a statue of limitations, Gjert is not on trial for the aforementioned incidents, as they happened more than 10 years ago. I think this interview leaves little doubt that, indeed, the brothers are right to pursue charges and distance themselves from their father.
