Well - not a particularly compelling case by the Channel 5 investigation into Jack the Ripper against Aaron Kosminsky but rather better than the last effort portrayed on this Blog. So, he went mad and was committed to an asylum by his family, lived in Whitechapel and was the right height. Very little beyond that other than he was suspected by two detectives of the day.
For me Francis Tumblety remains the lead suspect with Aaron Kosminsky as a rather poor second candidate. The Police at the time were so convinced that it was Tumblety that they followed him to America!
