Constance Hatchaway was a beautiful woman born in Money County, California supposedly in the year 1851. By 1869, an 18-year-old Constance had moved to Secret County, California where she became engaged to a young farming-heir named Ambrose Harper. Not long into their marriage, the teenage Constance murdered Ambrose with a hatchet via decapitation. Being Harper's wife, she inherited much of his estate while also keeping his severed head within a hatbox as a twisted souvenir.

The murder of Ambrose Harper was the first instance of Constance's modus operandi as a serial killer. Constance would target wealthy men and murder them with her hatchet before stuffing their heads inside of hatboxes as trophies. Through this habit, Constance would garner more and more wealth and status. An apparent affiliate of hers, at some point in her criminal career, was a man of unknown identity who came into possession of her hatboxes at some point in time.

Constance's next victim came in 1872 in the form of Frank Banks, an eastern banker, and community pillar. Two years later, Constance married the foreign diplomat and Chinese military officer the Marquis de Doome and in doing so presumably became the Marchioness de Doome herself. A year later she married celebrated railroad baron, gambler, and world-renowned gourmand, Reginald Caine. All of these husbands would fall to her blade and have their belongings and heads become part of Hatchaway's collection.

in 1877, the now 26-year-old Constance married one George Hightower of the wealthy Hightower family. By this time, Constance had left California and went on to move into a grand manor which George came into possession of. This manor  was however haunted by many spirits and deemed, "The Haunted Mansion" by locals. Regardless, Constance used the mansion's attic to hide away her many incriminating belongings.

Jigsaw is described as a mysterious person who kidnaps people he believes take their lives for granted and subjects them to "tests", usually mechanical devices rigged to maim or kill the subjects if they fail to complete it within a certain time period. Unlike most killers, Jigsaw never intends to kill his subjects; the purpose of his traps is to see if the subject has the will to live, as he hopes their experience will teach them the value of life, although he sometimes places his victims in situations where they themselves must kill others in order to follow the terms that he sets.

This used to be a funhouse
But now it's full of evil clowns
It's time to start the countdown
I'm gonna burn it down
9, 8, 7, 6, 5, 4, 3, 2, 1, fun

The moon made me do it!

The large number of attacks against women in the East End during this time adds uncertainty to how many victims were murdered by the same individual. Eleven separate murders, stretching from 3 April 1888 to 13 February 1891, were included in a London Metropolitan Police Service investigation and were known collectively in the police docket as the "Whitechapel murders". Opinions vary as to whether these murders should be linked to the same culprit, but five of the eleven Whitechapel murders, known as the "canonical five", are widely believed to be the work of the Ripper. Most experts point to deep slash wounds to the throat, followed by extensive abdominal and genital-area mutilation, the removal of internal organs, and progressive facial mutilations as the distinctive features of the Ripper's modus operandi. The first two cases in the Whitechapel murders file, those of Emma Elizabeth Smith and Martha Tabram, are not included in the canonical five.

Tabram was murdered on a staircase landing in George Yard, Whitechapel, on 7 August 1888; she had suffered 39 stab wounds to her throat, lungs, heart, liver, spleen, stomach, and abdomen, with additional knife wounds inflicted to her chest and groin. All but one of Tabram's wounds had been inflicted with a bladed instrument such as a penknife, and with one possible exception, all the wounds had been inflicted by a right-handed individual. Tabram had not been raped.
