Question: Name the American female serial killer, who after her arrest confessed to 33 murders, and who with only Lydia Sherman and a farmwife in rural Catawissa accused of murdering 17 members of the local community completes the trio of American female serial killers?

full_context: Document 1: Lynching of Marie Thompson of Shepherdsville: The lynching of Marie Thompson of Shepherdsville happened on June 14, 1904 in Lebanon Junction in Shepherdsville, Bullitt County, Kentucky for the murder of a white farmer. Marie Thompson, referred to by one reporter as a "negro Amazon," had attempted to break up an argument between John Irvin and her son over an alleged missing pair of pliers. Thompson claimed that she cut Irvin with a razor in self-defense.
Document 2: Bertha Gifford: Bertha Gifford (October 1872 – August 20, 1951) was a farmwife in rural Catawissa, Missouri during the early 1900s who was accused of murdering 17 members of the local community. Some consider her to be America's third female serial killer, behind Lydia Sherman and Jane Toppan.
Document 3: Charles Cullen: Charles Edmund Cullen (born February 22, 1960) is a former nurse who is the most prolific serial killer in New Jersey history and is suspected to be the most prolific serial killer in American history. He confessed to authorities that he killed up to 40 patients during the course of his 16-year nursing career. But in subsequent interviews with police, psychiatric professionals, and journalists Charles Graeber and Steve Kroft, it became clear that he had killed many more, whom he could not specifically remember by name, though he could often remember details of their case. Experts have estimated that Charles Cullen may ultimately be responsible for 400 deaths, which would make him the most prolific serial killer in American history.

Document 5: Jack the Ripper: Jack the Ripper is the best-known name for an unidentified serial killer generally believed to have been active in the largely impoverished areas in and around the Whitechapel district of London in 1888.
