Duh, you think I don't know that? The FBI will also tell you that they only know of few serial murderers in our society. Many are in the cocooning stage and trolling stage--which means they haven't killed yet. EVER, as you so brazenly put in bold, only refers to the past up to now. Evolution takes time. There may be many cross breeds of serial killers in this country that will not strike for years now--I do believe that some are operating right now and just have not been caught yet. (Since you are so wise in the ways of serial killers, you would know that they do not get caught unless they make a mistake, get arrested for another crime, confess, or kill themselves--)
Also, you say, insane people leave lots of evidence behind. Was Ted Bundy not insane to you? How about Dahmer? These were just a few that operated amongst other people for years without anyone noticing what was really going on in their heads.
And, either way you want to cut it, this offender was not insane in the legal sense of the word. He/she may not have staged the scene perfectly, but they had the know-how and composure to do it---and obviously get away with it. I have never stated that I thought the killer was just a maniac running loose through the house. (see William Heirens)
