A third murder in so many days was linked to Black Hand, an extortion racket similar to gangs but not organized like the Mafia.
A grieving widow left a note suggesting she would kill herself over her husband’s grave.
A “feminine Bluebeard” was suspected after at least 4 of her husbands were poisoned. A Bluebeard is a man who kills his wives; this article apparently predates the term Black Widow.
