Netflix's true-crime anthology series Monster returns for its fourth season on September 17, focusing on the 1892 murders of Andrew and Abby Borden.
Lizzie Borden was accused of killing her father and stepmother with a hatchet in Fall River, Massachusetts, but was acquitted by a jury in June 1893.
The case remains an unsolved historical mystery, with the true events following the acquittals continuing to captivate public interest.
