A man who is about to commit suicide calls 911. When his body is discovered there is also the shock of a room covered with photographs and clippings of women who have obviously been the victims of this man over more than a decade.
A detailed journal concerning the deaths is found and it is soon noted that the names of the dead women are tattooed somewhere on his body. Just one photo is found which does not have a corresponding tattoo and this leads the BAU to believe that the girl, who has been missing for approximately three weeks, is still alive somewhere. The question is, where? And how will they find her given that the killer is now dead?
A very disturbing ending which I won't spoil but one which you may find interesting without actually being surprised by it.
