The man charged with this summer's Øyer murder returned to the apartment on Wednesday, where he admitted killing his stepfather. Kim Andreas Kristiansen killed Bjarte Hansen with a knife before carving him up and taking his remains to be burnt on a campfire. The 23-year-old stepson is also reported to have cut the fingertips off Hansen's hands to make identifying the body more difficult, according to VG. Police questioned Kristiansen in the apartment where the murder happened on the night of August 14th. Police chief Bjørn Egil Bergundhaugen said: "It was the charged man and his defence lawyer who requested this and we had no arguments against it. We think that all parties are well served from doing this. This is a step in our investigation where the chain of events and the motives are key. Egil Bergundhaugen would not comment as to whether there were discrepancies between what the charged man said and the findings the police have made. Kristiansen claims he has no memory of events on the night of the murder or the threats to his friends, but has admitted the charges against him are plausible. The dead man's body was driven a few kilometres to a forest where Kristiansen and his accomplice tried to bury the body in the ground. When they did not succeed, they set the dead man alight.
