@szbalint This is true. The forensic pathologist's name is Pétur Guðmann Guðmannsson. He did a few seminars for crime writers via the continuing education centre of the University of Iceland where he's an assistant professor
I don't think he does the seminars any more but AFAICT he's still answering email questions from writers
CBC did an interview with him a couple of years ago https://www.cbc.ca/radio/asithappens/iceland-forensic-pathologist-1.6911486
