Ahaya	Cuscowilla Spanish Florida	1730s–1783	86+	Seminole chief, called "Cowkeeper" by the British, who led continuous raids against Spanish garrisons and their allied tribes in Florida. Although his killings were done during war parties, he was partially motivated by a dream in which he was revealed that he would not find peace after death unless he killed 100 Spaniards.

Behram is often cited as one of the most prolific serial killers in History (if not the most) with up to 931 victims, although he only admitted to have been present for that many murders, committing 125 himself and witnessing 150 or more. Thuggee victims were travellers that the Thuggees latched to and befriended before strangling them with a ceremonial handkerchief (rumal) and stealing their belongings.

"Big" Harpe was shot and beheaded in 1799 by people who sought vengeance for the murder of a woman, while "Little" Harpe was arrested when he took fellow outlaw Samuel Mason's head to the authorities and tried to collect a bounty put on him in 1803, but was recognized, tried and hanged in 1804.

Cannon, reportedly aroused by the sight of black males being beaten into submission, was arrested when four skeletons (three children, one male adult) were found buried in her property, though most of the gang's victims were probably rival white slavers. Cannon died in prison while awaiting trial, under unclear circumstances.
Mary Bateman	United Kingdom	1803–1808	1–4	"The Yorkshire Witch". Leeds career con woman and thief, hanged in 1809 for the arsenic poisoning of a married couple she had been scamming (the husband survived). Suspect in three more deaths.

The owners, Pierre and Marie Martin, and a valet, Jean Rochette, were believed at the time to have murdered up to 50 or more travellers that stayed in their inn of Lanarce, Ardèche to rob them, but were tried for only one murder that has been questioned since by historians. All three were guillotined in front of the inn in 1833.
Anna Maria Zwanziger	Germany	1808–1809	3	Housekeeper who poisoned her employers with arsenic and nursed them back to health to gain their favor; three died. Sentenced to beheading in 1811, which she welcomed as the only way to keep herself from poisoning people.
John Williams	United Kingdom	1811	7	Irish sailor who murdered two families and their servants in London's East End by bashing their heads with a hammer and cutting their throats. Hanged himself in prison while awaiting trial.
Gesche Gottfried	Bremen Hanover	1813–1827	15	Believed today to have suffered of Munchausen syndrome by proxy, as she poisoned several of her relatives and friends with arsenic for no apparent reason. Last person publicly executed in Bremen, where she was beheaded in 1831.
Konstantin Sazonov	Russia	1814–1816	6–7	Servitor at Tsarskoye Selo Lyceum. He killed six or seven persons at 1814–1816.
Samuel Green and William Ash	United States British North America	1817–1821	30	Itinerant burglars, robbers and counterfeiters, sometimes acting in solitary and others in association. Green, considered "America's first Public enemy number one", was also a rapist and the more violent and prolific killer of the two, while Ash helped him escape from prison multiple times. While serving a sentence for burglary, Green beat a fellow prisoner to death with an iron rod for informing the guards of an upcoming escape plan, and was hanged as a result in 1822.
Thomas Jeffries (or Jeffrey)	Australia New South Wales Van Diemen's Land	1820–1826	1–8	Called "Captain Jeffries" (a name he gave himself). Navy deserter, robber and conman deported to Australia in 1820. He escaped the penal colony with four other convicts in 1825. While on the run, the party broke into a hut and later the Tibbs settlement. Here they killed one man, severely injured another and kidnapped Mrs Tibbs and her baby. Jeffries himself is known to have murdered the Tibbs infant before likely assaulting Mrs Tibbs and letting her go. Following this the escapees retreated to deeper bush land. Facing starvation, they killed one of the party for food before joining up with bushranger gangs. During his time as member of bushranger gangs he undoubtedly was party to more violent crimes but too little is known to link any murders to Jeffries alone. With only one murder, that of the Tibbs infant, committed on record, Jeffries is more accurately described as a violent bushranger and serial rapist than serial killer. Records indicate he was charged with two rapes, in addition to that of Mrs Tibbs during 1825 alone. He was also reputedly ejected from bushranger Matthew Brady's gang for molesting women Hanged.
Edme Castaing	France	1822	1–2	Physician believed to have poisoned two lawyer brothers with morphine in the span of three months, although he was only convicted of murdering the second victim and destroying the will of the first one. Guillotined in 1823.
Alexander Pearce	Australia	1822–1823	2–5	Irishman deported in 1819 to Tasmania. He escaped the convict settlement with seven other convicts in 1824 into the Bush. The group was led by Robert Greenhill by because he was the only one with a weapon - the axe used to kill members of the party for food when starvation ensued (ironically in a region abundant with edible plants and other bush tucker). After the first such murder for survival (unlikely to have been committed by the undersized weaponless Pearce), 3 of the seven decamped. Pearce escaped being the second of the party murdered for food before one of the remaining three was fatally bitten by a snake. Only Pearce and Greenhill remained. Pearce was the only one left alive to reach the eastern settlements. Pearce was recaptured and sent back to Macquaire Harbor convict settlement as his claims of murder and cannibalism weren't believed, and escaped soon after with another convict, Thomas Cox. This time Pearce killed and ate his companion in less than ten days, when he surrendered voluntarily to the authorities. It is difficult to justify calling Pearce a serial killer as he only killed two people on his own and was at most one of Greenhill's accomplices in two earlier survival murders. However, if more than fictional sensationalism to sell newspapers, his reported last words of “Man's flesh is delicious. It tastes far better than fish or pork" suggest he may have become one had he lived. Hanged in 1824.
William Burke and William Hare	United Kingdom	1828	16	Lured, intoxicated and murdered people to sell their bodies to Dr. Robert Knox who used them in his anatomy classes at Edinburgh Medical School. Their usual method was compressing the chest of the victims in a process henceforth known as "burking". Hare was given immunity in exchange for testifying against Burke, who was hanged in 1829, while Knox was never prosecuted. Burke's fiancée was also tried but her implication was found not proven.
Thomas Griffiths Wainewright	United Kingdom	1830	1–4	Writer and painter believed to have poisoned his sister-in-law to collect a life insurance he recently purchased, and possibly also his uncle, mother-in-law and a friend. Having fled to France, he was arrested upon his return to Britain in 1837, but could not be prosecuted for lack of evidence. Instead he was tried for, and found guilty of, an unrelated case of forgery, for which he was exiled to Tasmania, where he died of natural causes in 1847.
John Bishop and Thomas Williams	United Kingdom	1830–1831	5	Called the "London Burkers". Copycats of Burke and Hare that were active in London. Hanged.

Seven chained and mutilated slaves were rescued after a fire broke out in LaLaurie's mansion, of which two died of their injuries shortly after, and three buried skeletons were later discovered in her property (according to witnesses, one had died in an accident). The case caused outrage in Louisiana but LaLaurie fled to France and was never prosecuted. Died of natural causes between 1842 and 1849.

She poisoned during two different periods separated by ten years, 1833 to 1841 and her final spree in 1851. Because the statute of limitations for the first spree had already run out, she was only tried for three murders and three attempts and guillotined in 1852.
Pierre François Lacenaire	France	1834–1835	2	Poet, army defector and thief. Helped by two accomplices, Lacenaire stabbed a former prison cellmate and his mother in Paris, and later attacked a bank employee that survived. They intended to rob the victims but none of the hits produced any money. While in prison for an unrelated offense, one of the accomplices, Victor Avril, blamed Lacenaire for the murders, and Lacenaire reacted by making a detailed confession that ensured both Lacenaire and Avril would be found guilty and executed. Lacenaire's response and his willingness to answer letters and receive visitors in prison, along with the publication of his memoirs, made him a celebrity. The two men were guillotined in 1836.
Hannah Hanson Kinney	United States	1835–1840	0–3	Believed at the time to have poisoned two husbands and a father in law; although arsenic was found in two bodies, she was found not guilty because of lack of further evidence.

His acquittal at a murder trial in 1835, while his two accomplices were hanged, had convinced him that God approved of his crimes. Hanged in 1842.
Sarah Dazley	United Kingdom	1840–1843	1–3	Hanged for the murder of her second husband, who was poisoned with arsenic. Believed to have poisoned her first husband and child as well.

In 1847, his pregnant wife, a member of the Flathead Nation, was killed and scalped by Crow warriors. Johnson is said to have embarked then on a vendetta against the Crow Nation that lasted for years and during which he murdered, scalped and ate the livers of 300 Crow warriors, although Thrapp (1991) considers this number inflated and incompatible with the Crow population at the time. Died of natural causes in 1900.
Manuel Blanco Romasanta	Spain	1844–1852	9–14	"The Werewolf of Allariz". While on the run from his first murder (a constable killed over a debt), Romasanta assumed a new identity and offered his services as a mountain guide to women and children, whom he murdered, later selling their clothing (and according to rumor, also making soap made from their body fat). Following his arrest, he confessed to 13 murders, which he claimed were committed involuntarily during his transformation into a wolf as a result of a curse. He was found guilty of nine and sentenced to die by garrote. This was changed to life in prison following a petition by doctors who wished to study him further. He died in jail in 1863.
Edward Rulloff	United States	1844–1870	2–7	Called "The Genius Killer" and "The Man of Two Lives". Medical doctor and philologist who had a parallel career as an armed robber and con man.

He has been characterized as the first serial killer in Finland.
Diogo Alves	Portugal	1836-1841	70+	Serial killer, who murdered 70 people in Águas Livres Aqueduct between 1836 until his execution in 1841, thus earning the title "Aqueduct Murderer".

Legendary serial killers

The existence of the following serial killers is dubious or contradicts the accepted historical record:

Name	Country	Time Period	Notes
Andrew Christie	Scotland	1320–1339	Called "Christie-Cleek". Purported Perth butcher turned road bandit, murderer and cannibal during a severe famine.
Christman Genipperteinga	Holy Roman Empire	1568–1581	Claimed German bandit who was executed for 964 murders, according to a 1581 pamphlet. Possibly inspired by real bandit Peter Niers, who confessed under torture to 544 deaths and was executed in the same year, although similar characters appear in German fairy tales and folk songs from before that time.
Sawney Bean's clan	Scotland	1575–1600	Claimed cannibal family that robbed, killed and ate travellers in a cave of Bennane Head, until their manhunt and execution by James VI. Contemporary documents make no reference to the hundreds of disappearances and murders said to have been carried by Bean's clan, which was probably inspired by the earlier legend of Christie-Cleek.
Sweeney Todd	United Kingdom	1790–1801	London barber said to kill his clients by slashing their throats and/or throwing them through a trapdoor, after which an accomplice would make pies with the meat of their bodies. Introduced in the 1846–1847 penny dreadful The String of Pearls, Todd was first claimed to be a real criminal in the first published edition of 1850, supposedly tried in December 1801 and executed in January 1802. Court records of the time do not mention Todd or anyone similar.
Don Vincente	Spain	1834–1836	Bibliomaniac ex-monk and librarian said to have killed ten men in Barcelona in order to steal unique books and add them to his collection, sentenced for his crimes to die by garrote. The story, first published as an anonymous article in an 1836 Parisian newspaper, was reprinted as a true story in France for a century, while remaining largely unknown in Spain.
Agnus McVee, Jim McVee and Al Riley	Canada	1875–1885	Family claimed to have owned a hotel and store on the Cariboo Road of British Columbia during the Cariboo Gold Rush, where they killed miners for their gold and kidnapped women to make into sex slaves until their arrest and death in prison in New Westminster. The story comes from a single source and there are no records of disappearances in the area at the time of the murders nor existing death certificates of the supposed serial killers apprehended.
