Alright lads. I'm looking for a scifi book I read as a teenager so roughly 15 years ago.
It was about murders taking place in a human society on earth where teleportation technology exists. Your original body gets destroyed and an exact replica appears at the destination. Someone hijacked that system to create another copy somewhere which then gets brutally murdered and tortured. So it is a crime story following some police guy trying to figure it out I believe.
