* Tumblety fits many requirements of what we now know as the ‘serial killer profile.’ He had a supposed hatred of women and prostitutes (the abortion with the prostitute Dumas, his alleged failed marriage to an ex-prostitute, his collection of uteri, etc.)
* Tumblety was in London at the time and may indeed have been the infamous ‘Batty Street Lodger’ -- he therefore may have had fair knowledge of the East End environs.
* Tumblety may have had some anatomical knowledge, as inferred by his collection of wombs, his ‘medical’ practice, and his short-term work with Dr. Lispenard in Rochester.
* He was arrested in the midst of the Autumn of Terror on suspicion of having committed the murders.
* There were no more murders after he fleed England on the 24th November, if one counts only the canonical five murders.
* Chief Inspector Littlechild, a top name in Scotland Yard, believed him a ‘very likely suspect,’ and he was not alone in his convictions.
* Tumblety was fond of using aliases, disappearing without a trace, and was the subject of police enquiries before his arrest.
* Scotland Yard and the American police had been in touch numerous times concerning Tumblety’s flight from France to New York.
* One of the three detectives inspectors assigned to the case was sent to New York at the same time, perhaps to pursue Tumblety.
* Tumblety evaded capture in New York City once again.
* Tumblety had the wealth necessary for frequent travel and could afford to change his clothes frequently should they have become bloodstained.
* He was an eccentric; but shrewd.
* He had a tendency toward violence at times, and his career may have included other offences both at home and abroad.
* Several acquaintances of his in America believed it likely that he was the Ripper when interviewed in 1888.
* There is a strong case to be made that he was indeed the Batty Street Lodger.
