Er...we know there were two killers, and one has already been identified and done a suicide-by-cop! :)) The pattern thus far of this riveting series seems to be to introduce a new suspect/red herring at the start of alternate episodes, and show how he cannot be the culprit in the following episode. In between these 2 events we get to holler from behind the sofa at Lund for stupidly going into darkened, perilous buildings without back-up, flashlight, gun, portable nuclear weapon etc etc. With just 2 hours to go I still think it could be Rie's dad!B)
