I find it interesting that none of the canonical five Ripper victims had traces of venereal diseases. This is despite residing in a ,area in which social reformers then and social workers now say was thick with diseased ridden prostitutes. Some people have even fingered suspects all because their suspects have had a STD and there has been speculation the murders were done out of revenge against a prostitute who might have infected them. Now some might say that any prostitute would be considered lucky if they worked in Whitechapel and had not caught a sexually transmitted disease, but one sure thing about the canonical five is that they were not lucky. Five 'randomly' selected women who had worked for years of prostitutes, were all disease free. Either all the talk about diseased prostitutes was mere hype or there is something more to it. Perhaps the killer somehow knew or could accurately gauge their medical history. Or is it some bizarre coincidence?
