Which detective could not solve the case of Jack The Ripper?

Answer 1

There were several different detectives that worked the Ripper case. As is done in todays murder cases they split the murders between the detectives so everyone gets their share of the work. And remember that at least one of the murders, Katherine Eddows, was in a completely different section of London known as The Mile. This murder was handled by the London Police as opposed to the Metropolitan Police for the other killings.

But the detective that is most often associated with Jack The Ripper is Inspector Frederick Abberline. Abberline was a much-commermorated member of the Metropolitan Police and was one of the few who never wrote a book or gave an opinion as to whom he thought the Ripper was. In his memoirs written after his retirement in 1903 he certainly did not go into the case. Maybe more than any of the other detectives that worked these murders, I think the inability to solve the case weighed heavily on Abberline, and most people don't like to talk about what they perceive as a failure. I think it is also telling that with all the rumors and misinformation that surrounded this case, he did not want to add another opinion to add to the confusion.
