On September 4, 1894, serial killer H. H. Holmes murdered his accomplice Benjamin Pitezel at 1326 Callowhill Street in Philadelphia. The original scheme called for Pitezel to fake his own death under the alias 'B.F. Perry', supposedly killed in a lab explosion, with Holmes supplying a substitute corpse so that Pitezel's wife could collect a $10,000 life insurance policy. Instead, Holmes knocked Pitezel unconscious with chloroform and burned his body with benzene, staging the death as an accident.
A coroner's jury returned a verdict of accidental death, and Pitezel's body was buried in a potter's field. Three weeks later, Holmes collected the $10,000 payout. The murder only unravelled after Philadelphia detective Frank Geyer investigated, ultimately exposing Holmes as one of the most prolific killers in American history.
