What hair colour did Jack the Ripper have?

Answer 1

Until he is posititvely identified we will never know for sure, but the people that may have seen him shortly before or after some of the murders claim that he may have had light colored hair.

Contrary to the eye witnesses, Hollywood depicts the killer as dark and brooding, with cape and top hat, enshrouded in that famous London fog. The reality is probably somewhat different. What we know of serial killers today is how average many of them appear to the rest of the world. In fact many of these killers have what looks to be normal lives with the appearence of normal relationships, 'average joe' to all who know them.
