On Sept. 27, 1888, the apparent killer sent a letter to police. It’s known as the “Dear Boss Letter.”
The letter reads:
I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. That joke about Leather Apron gave me real fits. I am down on whores and I shant quit ripping them till I do get buckled. Grand work the last job was. I gave the lady no time to squeal. How can they catch me now. I love my work and want to start again. You will soon hear of me with my funny little games. I saved some of the proper red stuff in a ginger beer bottle over the last job to write with but it went thick like glue and I cant use it. Red ink is fit enough I hope ha. ha. The next job I do I shall clip the lady’s ears off and send to the police officers just for jolly, wouldn’t you? Keep this letter back till I do a bit more work, then give it out straight. My knife’s so nice and sharp I want to get to work right away if I get a chance. Good Luck. Yours truly,
Jack the Ripper
Don’t mind me giving the trade name.
PS Wasn’t good enough to post this before I got all the red ink off my hands curse it. No luck yet. They say I’m a doctor now. Ha ha.
One of the suspects was Montague John Druitt. Montague may’ve lived with his cousin, who was practicing medicine near where the murders occurred.
About a month before the first murder, Montague’s mother went insane, and he wrote in a note that he also feared he was going insane. He disappeared after the first murder, and his body was found floating in a river within four weeks after the final murder.
The third suspect was Aaron Kosminski, a resident of the area who spent some time in asylums after the murders.
He was known for his hatred toward women, particularly prostitutes.
There’s also the “Jill the Ripper” theory. The idea is that a woman was the killer, but police had been searching for a man, so it would’ve been easy for a woman to slip by without suspicion.
However, all eyewitness testimony points to the murderer being a man.
The fifth suspect is Prince Albert Victor Christian Edward. The theory that he was the murderer is also known as the “Royal Conspiracy.”
Prince Edward was known to frequent the areas where the victims were found, and some believe he may’ve contracted syphilis, which drove him to insanity and led to him committing the murders. This theory is mostly regarded as ludicrous, because there’s a lack of evidence to support it.
The seventh suspect is Joseph Barnett, who lived with Mary Kelly, the final Ripper victim. Barnett worked as a fish porter and it’s believed that he was in love with Kelly.
Barnett disagreed with Mary Kelly’s life as a prostitute, so some theorize that he committed the first murders to scare Kelly off the streets. Eventually she returned to the street to make ends meet. It’s believed that the two had a big fight that got violent, and Barnett moved out. 10 days later, Kelly’s body was found in her apartment. This could explain why the murders ended with Kelly’s death.
The eighth and final suspect is James Maybrick, who died one year after the murders.
There was a diary reportedly discovered under the floorboards of Maybrick’s estate, with a message signed by “Jack the Ripper.”
