A "48 Hours" team returned to the Lizzie Borden House in Fall River and spent the night in Abby Borden's bedroom to reexamine the still-unsolved 1892 double murder.
The visit focused on gaps in Lizzie Borden's account, especially her claim she heard nothing while Abby was attacked upstairs in a small house with thin walls and rooms stacked directly above one another.
The team also revisited physical evidence questions: investigators believed a small hatchet was the weapon, yet no blood was found on Lizzie's dress despite the brutality of the killings and the short timeline.
Andrew Borden, 70, and Abby Borden, 64, were found hacked to death on Aug. 4, 1892; Lizzie, then 32, was acquitted in 1893 after an all-male jury deliberated for a little more than an hour.
The report argues modern forensic methods and different views of female defendants might have changed the outcome of a case that still fuels books, films and now Netflix's "Monster: The Lizzie Borden Story."
