Lizzie Didn't Do It!

On August 4, 1892, an elderly couple living in Fall River, Massachusetts, was slaughtered with a hatchet. Their daughter, Lizzie Borden, was first accused of the crime, then tried for it, and acquitted of it by a court of her peers. Yet, "conventional wisdom" and Fall River Society have always considered Lizzie guilty. "If Lizzie didn't swing the hatchet, who did?" they asked blamefully.
Now, after more than a century, the late University of Connecticut full Professor, William Masterton, uses modern forensic and extensive research to answer that question convincingly.

Lizzie Borden took an axe
And gave her mother forty whacks;
When she saw what she had done
She gave her father forty one.

The rhythm and rhyme of the refrain may be defective; the conclusion according to Professor Masterton, that Lizzie Borden may have been the killer, is not!
