You will forgive me if I give more credibility to an FBI profiler that worked on the case than to some guy/gal on an internet chitchat forum.
After reading a biography of J. Edgar Hoover, I wouldn't give any credibility to anyone connected to the F.B.I., furthermore the F.B.I. is a U.S. organization, sweet little Karla last I heard was Canadian not to mention being a prolific killer. Bitch should have fried as far as I'm concerned. Anyway keep grasping at straws there Einstein!
