According to a programme on tv last week, a self taught American doctor, whose name escapes me was almost certainly the ripper. Apparently he had a profound hatred of women, lived in a B&B next to one of the killings, In fact, a bloody shirt was found in his room after he fled the country after one of the killings. And every time he left the country there were no more killings, Supposedly the police knew he was the ripper but, as with today, if they had no evidence they couldn't convict, and as there was no forensics back then. I'll find his damn name, i tells ya.
