One think that has always baffled me is, how on earth could one person risk being caught?, there had to be more than one. There must have been a look out at least, Mary nichols, nobody heard or saw anything that night!, Annie chapman, blood was found trailing through the corridor of no 29 to the back yard!. What i still cannot believe is how the hell did one person get from berner street to mitre square, find C E, kill her so visciuosly without someone coming up from behind and catching him in the act?. Still nobody saw or heard anything unusual, mitre square was patrolled every 15 minutes!, i just don't buy it that one person could have done it, it's impossible.
