Killer description and Suspect appearance – Casebook: Jack the Ripper …

Yep, most of the descriptions have the Ripper as youngish but mature, age 30-40. Of course, a moustache and such can age a young man, so 23 year old Chapman might appear 30, just as an older man, such as Tumblety, if his hair was not grey, might appear 40. So, while it’s by no means science, the Ripper seems to have been around 30-40. Yours truly,
