Three or more blitz attacks on the streets of Claremont, and not one single person saw or heard anything? Also, all of the blitz attacks were successful and not one thing went wrong? This just defies belief that detectives think they were all blitz attacked. A blitz attack is not the CSK's style, he is too organised and meticulous in his planning to roll the dice on a blitz attack. Also, this does not explain he reason why the murders have stopped, why haven't more girls been abducted and murdered?
