On a sweltering August morning in 1892, the quiet streets of Fall River, Massachusetts, were shattered by one of the most brutal and enduring mysteries in American crime history. Andrew Borden, a wealthy but notoriously frugal businessman, and his second wife Abby were found savagely killed in their home. Their daughter Lizzie stood accused. More than 130 years later, people still ask the same charged question: Why did Lizzie Borden kill her parents?
The short, honest answer is that we cannot say with certainty that she did. A jury acquitted her in 1893. Yet the circumstantial case against her remains strong enough that most historians and true-crime enthusiasts still view her as the most likely perpetrator. What follows is a clear-eyed look at the family pressures, possible motives, and lingering doubts that keep the story alive.

The Grisly Crime That Shocked Fall River
On August 4, 1892, Abby Borden was attacked first in an upstairs guest room, receiving roughly 19 blows from a hatchet. About 90 minutes later, Andrew Borden was killed downstairs on a sitting-room sofa with 10 or 11 strikes, many aimed at his face. No forced entry. No robbery. The house was occupied that morning by Lizzie and the family’s Irish maid, Bridget Sullivan. Lizzie’s older sister Emma was out of town.
The violence was extreme for a domestic crime of the era. Neighbors heard nothing. No bloody clothes were found on Lizzie. Yet she was the only person with both opportunity and a plausible reason to resent the household’s tight control over money and independence.
Family Tensions and the Inheritance Motive
The Borden home was not a happy one. Andrew had remarried after the death of Lizzie and Emma’s mother when Lizzie was a toddler. The sisters never fully accepted Abby, often referring to her as “Mrs. Borden” rather than mother. Meals were taken separately. Resentment deepened when Andrew transferred property to Abby’s relatives while keeping his own daughters on a short financial leash despite his considerable wealth.
Prosecutors argued that Andrew was considering a new will that would have favored Abby more heavily. In an era when unmarried women had limited options, the prospect of a reduced inheritance could have felt catastrophic. Lizzie and Emma later inherited the bulk of the estate after the murders and moved to a far more comfortable house. Money and long-simmering family friction remain the strongest traditional motives cited by those who believe Lizzie committed the crime.
Circumstantial Evidence That Pointed to Lizzie
Several details kept suspicion focused on her:
- The day before the murders, witnesses claimed Lizzie tried to buy prussic acid (a deadly poison) at a local drugstore, saying she needed it for a sealskin coat. The purchase was refused.
- She gave inconsistent accounts of her movements that morning.
- Days after the killings she burned a dress, claiming it was stained with paint.
- She corrected officers sharply when they referred to Abby as her mother.
Much of this evidence was either excluded at trial or never fully explained. No definitive murder weapon with blood was linked to her, and the all-male jury took little more than an hour to acquit. Still, the combination of opportunity, strained family relations, and odd behavior left a lasting shadow.
Alternative Theories and Why the Mystery Endures
Not everyone accepts Lizzie’s guilt. Some point to the maid Bridget, others to an alleged illegitimate half-brother, or to an unknown outsider with a grudge against the miserly Andrew. A few theorists have even suggested Emma returned secretly. None of these alternatives has stronger evidence than the case against Lizzie.
Modern interest stays high. The house is now a bed-and-breakfast and museum. Books, documentaries, and recent streaming projects continue to re-examine the case. Fresh forensic techniques cannot be applied to the original physical evidence, so the debate remains largely historical and psychological.

Conclusion
Whether Lizzie Borden swung the hatchet will likely never be proven beyond doubt. The strongest case against her rests on opportunity, a household simmering with quiet hostility, and the very real possibility that a restricted, unmarried woman saw her financial future slipping away. The jury’s not-guilty verdict protected her from the gallows, yet public imagination has never fully released her. The rhyme still circulates, the house still draws visitors, and the question still hangs in the air: Why would a churchgoing Sunday-school teacher kill her parents? The evidence points one way. Certainty, however, remains just out of reach—even in 2026.
