Mei Trow believes it to be Robert Mann, a morgue attendant. Trow has used up to date CSI forensic techniques as well as current psychological profiling and also geographical profiling.
In 1988 the FBI took an examination of the Ripper case which led to an apparently rather comprehensive criminal personality profile:
This profile described the killer as lower class white man probably the product of a broken home, he had a menial job and would’ve had some anatomical knowledge. Maybe a butcher, mortuary assistant or possibly a hospital porter and because of the solitude of his job he may well of found it difficult to interact with others and could’ve been rather socially inept, possibly somewhere on the autistic spectrum.
Mann who I have never heard of was generally fatherless and spent much of his time a child in a workhouse, but then again that could describe many, many poor people.
“I wanted to go beyond the myth of a caped man with a top hat and knife, and get to the reality, and the reality is simply that Jack was an ordinary man.” states Trow.
He also believes that Martha Tabram was stabbed to death in Gunthorpe Street may well have been his first and an Alice Mackenzie may have been his last.
In terms of psychological profiling, Robert Mann is the one of the most credible suspects from recent years and the closest we may ever get to a plausible psychological explanation for these most infamous of Victorian murders.” explains Professor Laurence Alison, Forensic Psychologist from Liverpool University.
However, it is worth bearing in mind that with more than 100 suspects over the years, Robert Mann will be another identity to add to the been proposed one over the years.
It is a fascinating mystery but one we probably never get to the bottom of!
