On August 4th, 1892, Andrew and Abby Borden were found hacked to death inside their Fall River, Massachusetts home. Their daughter Lizzie was charged, tried, and acquitted within a year, but the case has never been officially solved. This History Hit documentary revisits the crime scene, the inquest testimony, and the physical evidence with the eye of a modern cold-case review, asking why the original investigation moved so fast to convict Lizzie and skipped over other suspects. It lays out the household tensions over money and property that gave multiple family members a motive, and it picks apart the forensic shortcomings that would never survive scrutiny today, from the handling of the murder weapon to the autopsy itself. Historians walk through the timeline hour by hour, testing whether Lizzie could have committed the murders alone, acted with help, or been nowhere near guilty at all. The film treats the acquittal not as an answer but as the start of the real investigation, more than a century late.
