Many people might have wanted to see Andrew Borden dead.
The gruesome murders shocked the community, but many in Fall River were perhaps not entirely surprised that Andrew Borden had met an untimely end. With a net worth of almost $10 million in today’s money, Borden was one of the wealthiest—and most unpopular—men in town. Frugal to a fault, he was a self-made man who had become the head of one of the town’s largest banks and a substantial property owner. The dour businessman had also made many enemies on his rise to the top, and rumors swirled that Andrew and Abby had perhaps been killed as revenge for Andrew’s shady business dealings.
The case revealed some skeletons in the Borden family closet.
The initial investigation focused outside of the immediate family and included local businessmen, neighbors and even the family maid, an Irish immigrant named Bridget Sullivan. Police soon realized that Andrew’s daughter, Lizzie, had as much to gain as anyone by the death of her father. Andrew’s tightfistedness extended to his own family—despite his wealth, the Borden home lacked even the most basic of conveniences, including indoor plumbing. Andrew’s remarriage to Abby Gray after the death of his first wife had soured his relationship with Lizzie and her older sister, Emma. The women, already in their 30s and considered spinsters by society, grew increasingly frustrated and resentful, with Lizzie in particular often exhibiting signs of mental instability. Lizzie’s actions in the days after the murders also raised eyebrows: She gave contradictory answers to questions and burned a dress that she claimed had been stained while doing housework, which police considered the destruction of evidence. On August 11, Lizzie was arrested for the murders.
The lack of forensic evidence played a key role in the case.
There was no physical evidence linking her to the murders. A hatchet had been discovered in the basement of the Borden home, but its blade was clean and the handle had been broken off—by Lizzie, according to police. The police’s reluctance to use any sort of forensic testing also hampered the investigation. Fingerprint testing was then in its infancy and was never conducted as part of their inquiry. They did, however, establish that Lizzie had unsuccessfully attempted to purchase prussic acid, a highly poisonous liquid, in the days before the murders. Though investigators regarded this as evidence of an earlier failed attempt to kill her parents, they were unable to present it at trial.
