When I drove home at around one o’clock that night, having spent a couple of hours inspecting the scene and taking witness statements, I rather reluctantly had to admit that PC Eriksen’s conclusion still held true. We had a body, a crime scene and an indisputable murder, but not only did we not have a motive, a weapon or a suspect, we had no idea how the murderer could possibly have fled the victim’s flat after firing the fatal shot.
Viewed from outside, 25 Krebs’ Street was a rather ordinary three-storey brick tenement building in Torshov. The elderly caretaker’s wife who met me at the entrance told me that it had been sold and done up three years before. The improvements included a simple lift in the stairwell and bathrooms in all the flats. Otherwise, the building was more or less as it had been when it was built in the 1920s: big, grey and hard. It struck me that both the building and the caretaker’s wife could have been taken straight from Oskar Braaten’s novel The Wolf’s Den.
The drama that unfolded in 25 Krebs’ Street on the night of Thursday, 4 April 1968 had quite literally started with a bang at a quarter past ten. A shot was fired in the right-hand flat on the second floor that was heard all the way down to the ground floor. Olesen’s closest neighbour from Flat 3B was about to mount the stairs, but at that moment was having a neighbourly chat with one of the other residents on the ground floor. When they heard the shot from Mr Olesen’s flat, they both ran up the stairs immediately. The door to Flat 3A was locked and there was not a sound to be heard from within. A couple of minutes later, the pair were joined by a man from the first floor, who had left his wife and baby son in the safety of their flat and run up to the second floor. Then the caretaker’s wife came panting up the stairs. One of the residents on the ground floor was wheelchair-bound and therefore came up in the lift after several minutes. The last of the eight adult residents, a young Swedish woman, remained bolted into her flat on the first floor until the police rang the doorbell half an hour later.
Meanwhile, the neighbours out on the landing could only open the door to Harald Olesen’s flat once the caretaker’s wife had arrived with the key. After some discussion, they decided not to cross the threshold until PC Eriksen arrived half an hour later. Their fears of a shootout soon proved to be unfounded. There was no sign of a weapon in the flat, or any form of life. Harald Olesen was lying in the middle of the sitting-room floor with a bullet wound on the left side of his chest. The bullet had gone straight through him and was lodged in the wall. Otherwise the flat was in every way the same, as far as the caretaker’s wife could remember, as it had been the last time she was there – with no sign of the murderer or murder weapon.
