Would you pass Eastern State Penitentiary on April 3, 1945, just as famed bank robber Willie Sutton popped out of an escape tunnel in broad daylight? Or you might have been one of the invited guests at H.H. Holmes' hanging at Moyamensing Prison on a gray morning in May 1896. It still ranks as one of the most bizarre executions in city history. Or, if you walked down Washington Lane on July 1, 1874, would you have been alert enough to stop the two men who lured little blond Charley Ross away with candy? You might have stopped America's first kidnapping for ransom, the one that gave rise to the admonition, "Never take candy from a stranger." The case inspired the Leopold and Loeb kidnapping. Then there was the bank robber whose funeral drew thousands of spectators and the burglary defendant so alluring that conversation would stop whenever she entered the courtroom.
