Jack the Ripper

Jack the Ripper was a British serial killer (possibly prolific) and possible cannibal active in London during the late 1800's. He is widely considered the world's first and most infamous modern serial killer, mainly because he was never caught or even identified.

Background
"Jack" as he called himself, was active in the Whitechapel district of London, England during the late 1800's. Whitechapel itself was known as a Red Light District of the city; meaning that it was a haven for prostitutes, drug addicts, and gangsters. The London Metropolitan Police estimated that there were 1,200 active prostitutes at any given time, every one of them a potential target of a serial killer.

Involved chiefly in the investigation were inspector Frederick Abberline and Medical Examiner Thomes Bond. They were unsuccessful in capturing or even identifying the Ripper.

Suspects
There have been many theories concerning the identity of The Ripper, mostly involving royal figures, prominent businessmen, and even a female Jewish immigrant. These include, but are not limited to:

Modus Operandi
The Ripper targeted Caucasian female prostitutes in the Whitechapel area. He killed them by slashing their throats, proceeding to eviscerate them when they were dead. Because bruises older than the cuts were found on the necks of many of the canonical victims, it has been suspected that the Ripper strangled his victims into submission with his bare hands before slashing them. The murders would always occur on a Friday, Saturday, or Sunday, within the hours of midnight and 6:00 a.m. He would often take an organ or two as a trophy and once sent half of a kidney to George Lusk, head of the Whitechapel Vigilance Committee, as proof of his identity (the accompanying letter claimed that the killer had eaten the other half). It is reported that the body of Mary Jane Kelly was so grotesquely slaughtered that she was unrecognizable. Her body was also posed with the legs parted, as was another victim.

Profile
"I am down on whores and I shant quit ripping them till I do get buckled."

In the book The Cases That Haunt Us by John Douglas and Mark Olshaker, there was a profile of Jack the Ripper made by Douglas and Roy Hazelwood. According to them, the Ripper was a disorganized, paranoid killer. He would have been a white male in his late 20s to early 30s who was raised in a household marked by a passive or absent father and a dominant mother who may also have been promiscuous and/or an alcoholic. He later became an introverted, antisocial loner who set fires and tortured animals as an outlet for his anger. At the time of the murders, he would have been calm, quiet, and inconspicuous.

If he had a job, he would have chosen one in which he could pursue his interests, such as a morgue worker, butcher, mortician's assistant, low-ranking hospital staff, etc., since the way the Ripper cut out organs from his victims suggests some anatomical knowledge. The times of the murders indicate that he would have had days off on certain weekends and holidays and could come and go from his home as he pleased without anyone noticing. He was also probably neither married nor involved in any committed relationship, the majority of his association with women having most likely been prostitutes.

He may have had some physical defect that made him feel inadequate or unattractive. Because of a negative self-image, he displayed paranoid traits and carried one or more knives for self-defense purposes. Prior to the murders, he may have visited pubs and drunk in order to relieve himself of some tension. He may also have been seen wandering on the streets looking for potential victims. It is possible that he was at one point interviewed or questioned by the police.

Known Victims
All of the following were attacked in and around the Whitechapel district area

The "Canonical Five"
The five victims confirmed to have been murdered by the Ripper


 * 1888:
 * August 31, Buck's Row: Mary Ann "Polly" Nichols, 42
 * September 8, 29 Hanbury Street, Spitalfields: Annie Chapman, 47
 * The September 30 "double event":
 * Dutfield's Yard: Elizabeth Stride, 44
 * Mitre Square, the City of London: Catherine Eddowes, 46
 * November 9, 13 Miller's Court, Dorset Street: Mary Jane Kelly, 24

Suspected
Victims who were killed during the so-called "Whitechapel murders", which is heavily suspected of being perpetrated by the Ripper and also includes the Canonical Five


 * 1888:
 * April 2, Osborn Street: Emma Elizabeth Smith, 45
 * August 6, George Yard Buildings, George Yard: Martha Tabram, 39
 * December 20, Clarke's Yard: Rose Mylett, 29
 * 1889:
 * July 17, Castle Alley: Alice McKenzie
 * September 10, Pinchin Street : "The Pinchin Street torso"
 * February 13, 1891, Swallow Gardens: Frances Coles

Other Possible Victims
Other victims suspected to have been attacked by the Ripper that were not counted in the Whitechapel murders


 * 1888:
 * February 25, unspecified location: Annie Millwood
 * March 28, unspecified location: Ada Wilson
 * November 21, unspecified location: Annie Farmer
 * October 2, various locations : An unidentified woman
 * December 29, Manningham, Bradford: John Gill, 7
 * June 2-25, 1889, the river Thames: Elizabeth Jackson
 * Notes:
 * There is a serial killer dubbed "The Torso Killer", who was active near the river Thames, where the parts of his or her victims were discovered. He or she was suspected of having murdered, among his or her victims, the Pinchin Street torso and the "Whitehall Mystery" victim, as well as Elizabeth Jackson.
 * Carrie Brown, a.k.a. "Shakespeare" (reportedly for quoting William Shakespeare's sonnets), was briefly suspected of being a victim of the Ripper victim. Her body was found strangled with clothing and mutilated by a knife in New York City on April 24, 1891. Her murder was compared to the deaths at Whitechapel, but any connection between the two cases was ruled out.
 * Due to the fact he was never caught and the suspicion that he is responsible for many more murders leads to the possibility that Jack may be responsible for many more unsolved or undiscovered murders.

Legacy
There are no documents in the Whitechapel murder file dated after 1896. The murderer or murderers were never identified and the cases remain unsolved.

The poor of the East End had long been ignored by affluent society but the nature of the murders and of the victims drew attention to their living conditions. The murders galvanized opinion against the overcrowded, insanitary slums of the East End and led to demands for reform. On September 24, 1888, George Bernard Shaw commented sarcastically in a letter to The Star newspaper on the media's sudden concern in social justice:

''Whilst we conventional Social Democrats were wasting our time on education, agitation, and organization, some independent genius has taken the matter in hand, and by simply murdering and disemboweling ... women, converted the proprietary press to an inept sort of communism.''

Acts of Parliament, such as the Housing of the Working Classes Act 1890 and the Public Health Amendment Act 1890, set minimum standards for accommodation in an effort to transform degenerated urban areas. In the two decades after the Whitechapel murders, the worst of the slums were closed down and demolished.

Sensational reportage and the mystery surrounding the identity of the killer or killers fed the development of the character "Jack the Ripper", who was blamed for all or most of the murders. Hundreds of books and articles discuss the Whitechapel murders, and they feature in novels, short stories, comic books, and films of multiple genres. There is even an entire science dedicated to the Ripper murders called "Ripperology".

Some modern-day serial killers have been compared to the Ripper (a name which is sometimes part of their nicknames). An example is an unidentified English serial killer active between 1964 and 1965 nicknamed "Jack the Stripper", so named because all of his known victims were prostitutes who were found undressed, having suffered head injuries, died of various causes and been dumped in the Thames. Another is Peter Sutcliffe, a.k.a. "The Yorkshire Ripper", another English serial killer who also targeted prostitutes. He would strike them from behind with a blunt object and then stab them. Yet another is Colin Ireland, a.k.a. "Jack the Gripper", who would beat and torture his victims before killing them by some form of asphyxiation, though he didn't attack or mutilate any of his victims with a knife. Furthermore, the word "Ripper" is often included in the nicknames of serial killers whose murders often involved the use of sharp instruments and mutilation; examples include the aforementioned Sutcliffe; Andrei Chikatilo, a.k.a. "The Rostov Ripper"; Robert Napper, a.k.a. "The Plumstead Ripper"; and the uncaught Gilgo Beach Killer, who also had the nicknames "The Craigslist Ripper" and "The Long Island Ripper".

In 2008, a convicted rapist obsessed with serial killers, named Derek Brown, tried to copy the M.O. of the Ripper. Brown picked up a prostitute named Bonnie Berrett and a DVD seller, Xiao Mei Guo, in the same Whitechapel area where the Ripper was active. He then brought the women to his flat, where they were murdered and butchered in a bathtub. He was subsequently nicknamed the "Jack the Ripper Killer" by the press.

On Criminal Minds

 * Season Two
 * "Sex, Birth, Death" - Jack the Ripper is first mentioned when Nathan Harris tells Reid he has read a lot of Ripper-based literature, mostly comics. Later, Nathan is shown writing Ripper-related fan-fiction on his laptop. He may have also been an inspiration for the episode's unsub, Ronald Weems - Both were serial killers who operated on city streets at night, targeted Caucasian female prostitutes, used bladed weaponry to kill them, and wrote messages for the Authorities.
 * "Jones" - Jack the Ripper was mentioned again when Sarah Danlin began copying his M.O. (though she targeted men and killed more). One of his crimes was briefly dramatized.
 * "No Way Out" - While not directly mentioned or referenced in this episode or it's part 2, Jack the Ripper appears to have been an inspiration for the episode's unsub, Frank Breitkopf - Both were prolific (possibly in Jack the Ripper's case) serial killers who targeted the 'unwanted'/high-risk victims (mainly women), were incredibly sophisticated and organized killers, and performed vivisection and dismemberment on their victims with bladed weaponry.
 * Season Four
 * "52 Pickup" - While not directly mentioned or referenced in this episode, Jack the Ripper appears to have been an inspiration for the episode's unsub, Robert Parker - Both were serial killers who targeted prostitutes, slit their throats, and dismembered them.
 * "Zoe's Reprise" - Jack the Ripper was one of the many serial killers mentioned throughout this episode. He is also one of the killers who the episode's unsub, Eric Olson copied (murdered a prostitute named Lily Nicks, whose murder was inspired by Jack the Ripper's murder of Elizabeth Stride).
 * Season Eight
 * "Pay It Forward" - Jack the Ripper was mentioned as an example of serial killers who stop killing and disappear.
 * Season Eleven
 * "Tribute" - Jack the Ripper was mentioned again and was one of the serial killers the episode's unsub, Michael Peterson copied (murdered several women by sliting their throats and eviscerated them).
