Jack the Ripper: Letters, Theories & Suspects

| By Tara Blair |

Dear Boss,

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.

Yours truly,
Jack the Ripper

In autumn 1888, five women were murdered in the east London slums at the hands of an unknown killer. This murderer came to be known as “Jack the Ripper,” a man who repeatedly evaded and taunted the police.

During the Jack the Ripper murder era, police, media, and local officials received an onslaught of letters—making Jack the Ripper the first “media serial killer.” Due to his mystique and unknown identity, this case remains one of England’s most notorious unsolved cases.

The Letters

Although the vast majority of the letters were believed to be hoaxes, three stood out:

Note: To date, none have been proven authentic。

Dear Boss Letter

Dated September 25th, 1888,the Dear Boss letterwas received by the Central News Agency two days later, but didn’t gain attention until Catherine Eddowes’s murder on September 30^th。这封信提到了下一个受害者的耳朵。当她的身体被发现时，eddowes被剪切耳垂发现。

The letter was penned in red ink and, like many other Jack the Ripper letters, had many grammatical errors.

漂亮的水手明信片

Penned on October 1, 1888, and also addressed to the Central News Agency, theSaucy Jacky postcard有手写，模仿亲爱的老板信，墨水颜色和语法错误。它类似地写成了“老板”，并提到没有时间让“耳朵关闭”。明信片提到了伊丽莎白骑士和凯瑟琳·埃德罗斯的谋杀案，两者在9月30日发生^th, as a “double event.”

From Hell Letter

Perhaps the most disturbing of the three letters, theFrom Hell letterwas written for George Lusk, the chairman of the Vigilance Committee in Whitechapel. The letter contained a partial kidney, thought to belong to Catherine Eddowes. In the letter, the writer claimed to have eaten the missing part. While the letter was unsigned, the words “From hell” were written in the top right corner. It contains more grammatical errors than the previous two letters and the handwriting is unique.

Theories

There are countless theories about the identity of Jack the Ripper. Here are two feasible speculations:

Jack the…Butcher?

During this era, slaughterhouses were common and butchers often walked the streets wearing bloodstained clothing. This may explain how in the Catherine Eddowes’ murder Jack the Ripper was able to flee the scene quickly while covered in blood, and did not appear suspicious to patrolling police.

Another basis for thebutcher theoryis the fact that a butcher would have impeccable knife skills. Butchers are well-trained at cutting out the organs of animals before selling their meat, similar to the precision with which the kidney of Catherine Eddowes and the uterus of Annie Chapman were cut. Elizabeth Stride’s cause of death was one clear-cut incision that severed the main artery on her neck, which would require more than basic anatomic knowledge and skill with a knife.

…the Foreigner?

Another theory is that the murderer was anon-Englishman working on a foreign vesselthat traded regularly with London. This could explain his less than perfect grammar—although many theorize the murderer made these mistakes deliberately to misdirect the police (but that’s a theory for another time)—and the ease with which he escaped.

Suspects

在他们调查过程中，警方将几名男子视为强烈的嫌疑人，虽然没有人正式收取：

Montagu John Druit

Although there was no concrete, scientific evidence implicating him in the murders, the fact that the murders ended afterDruitt’s suicideconvinced many London detectives that Druitt was Jack the Ripper. He was an Oxford-educated man who some believed to be “sexually insane.” Witnesses reported him in the Whitechapel area around the time of the murders. On November 9, 1888, seven weeks after the murder of Mary Jane Kelly who is believed to be Jack the Ripper’s final victim, Druitt’s body was found floating in the Thames River. Investigators concluded that the cause of death was suicide, and that Druitt had been at the bottom of the river for at least several weeks—which matched the timing of Mary Jane Kelly’s murder.

  Carl Feigenbaum

  杰克背后的另一个可能的嫌疑人谋杀案Carl Feigenbaum，德国商人水手。当时，费伊班省曾担任船上附近的船上的商人。记录证明，在惠特查章工作的日子恰逢五千斤顶的日期，在伦敦东端发生的破解谋杀案。进一步暗示Feigenbaum，目击者将他和同伴们透露在附近的妓院的游客。

  

  
  

  Aaron Kosminski

  Several highly esteemed police officers presumed Aaron Kosminski, a polish barber, to be Jack the Ripper. The recent discovery of hismitochondrial DNA on Catherine Eddowes’s shawl, 126 years after her murder, adds to suspicions around Kosminski. Born in Russia in 1864, Kosminski settled in London in the early 1880s. He worked as a hairdresser in Whitechapel during the time of the murders.

  

  It is important to note that thetest results from the silk shawl, which was stained with blood, are controversial and at this time are not enough to prove Aaron Kosminski was Jack the Ripper.
