Lizzie Halliday

In May 1891, the Halliday mill/residence barn burned to the ground, killing Halliday's mentally handicapped son John. Lizzie was again suspected of setting the fire since she was known to have disliked John. She was arrested and sent to an asylum, transferred to another, but then declared cured and released, returning home to Halliday.[5]

Paul Halliday disappeared in August of that year. Lizzie claimed he had gone to a nearby town to do some masonry work. Following the neighbors' suspicions that something was not right about Lizzie's story, a search warrant was obtained and on September 4 the bodies of two women were found buried in hay in a barn. Both had been shot. The women were later identified as Margaret and Sarah McQuillan, New York residents who were part of the family Lizzie had stayed with in Philadelphia. Little could be ascertained from Lizzie as, when questioned, she behaved in an erratic manner, tearing at her clothes and talking incoherently. She was kept in custody and some thought she was merely faking insanity.

A few days after the McQuillans were found, Paul Halliday's mutilated body was discovered under the floorboards of his house. He had also been shot. Lizzie was charged with the murders and held for trial at the Sullivan County jail in Monticello, New York. During her first few months there she refused to eat, attacked the sheriff's wife, set fire to her own bed, tried to hang herself, and cut her own throat with broken glass about which she said: "I thought I would cut myself to see if I would bleed."[4] Her jailers were forced to chain her to the floor during her remaining months there.

While she was in jail Lizzie received national attention with one sensational story after another appearing across the country in tabloid newspapers. The New York World portrayed Lizzie's case as "unprecedented and almost without parallel in the annals of crime".[3] She was also covered by the World's Nellie Bly who eventually managed to get an interview with Lizzie in which she revealed her previous marriages, facts Bly was able to confirm. Another useful source for reporters was Robert Halliday, Paul Halliday's son. The Sullivan County Sheriff started a new round of speculation when he told the press that Lizzie was probably connected to the Jack the Ripper murders, although no connection was ever made.

The revelation that she had been married five times before she wed Paul Halliday, that two of her husbands died less than a year after their weddings and that Lizzie had tried to poison a third led the press to speculate that she was responsible for at least six deaths. "Whether these men died natural deaths or were murdered, is not known", The New York Times noted in June 1894.[3] Lizzie also made a claim (confided to Robert Halliday) that she had killed a husband in Belfast,[6] but had managed to conceal the crime.

On June 21, 1894, Halliday was convicted at the Sullivan County Oyer and Terminer Court for the murder of Margaret McQuillan and Sarah Jane McQuillan. She became the first woman ever to be sentenced to death by electrocution, via New York State's new electric chair. Governor Roswell P. Flower commuted her sentence to life in a mental institution after a medical commission declared her insane.[6][7][8][9]

Halliday was sent to the Matteawan State Hospital for the Criminally Insane where she spent the remainder of her life. In 1906 she killed a nurse, Nellie Wickes, by stabbing her 200 times with a pair of scissors.[10]

Halliday died on June 28, 1918.[11][12][13]
