"Martin Vanger had developed this peculiarity by keeping a "death book." He had catalogued and graded his victims. He had described their suffering. He had documented his killings with videotapes and photographs."(Pg. 506)
What I want to know his how come it took so long to catch him. He kept a record of who he killed how he killed them and all the details one needs to know in order to convict him. If someone did that in todays day and age they wouldn't get past the killing of 2 people the investigation would be so big. It is just mind boggling that they couldn't catch him faster then they did.
