The bodies of Andrew and Abby Borden were found by Lizzie and the family’s maid, Bridget Sullivan, after suffering crushing blows from a hatchet in their Fall River, Massachusetts home on August 4, 1892.

Lizzie soon became the prime suspect in the grisly double murder, with financial and property gain and a falling out with her step-mom being cited as the sinister motive.

Much of the evidence from the original investigation, including the infamous “handless hatchet’’ and a bloody pillow sham found at the scene of the crime were kept by the family’s attorney, Andrew Jackson Jennings, and now two handwritten journals penned by the lawyer may provide the missing pieces of the puzzle, reported the Boston Globe.

“It’s all new material, completely unpublished,’’ said Michael Martins, curator of the Fall River Historical Society, which recently acquired the journals. “It’s the only file Jennings retained, and it’s the first idea we have about how the defense went about building its case.’’

Jennings’ grandson, Edward Waring, left the journals to the society when he died last year after keeping them hidden during his lifetime out of fear that his grandfather may be misquoted because his handwriting was hard to read.

Specialists have now transcribed the pile of evidence, which includes notes, interviews with witnesses, newspaper clippings and legal notes, to shed light on Andrew Borden’s relationship with his daughters, Lizzie and Emma.

“It’s clear from what these people said that Andrew Borden was apparently quite concerned about his daughters’ well-being, and he often referred to them as his girls,’’ Martins said. “We know now that he was not a gentleman who deprived his daughters of much.’’
