The Cab-Hold-Up Affair / 7

The Muggings / 1

An hour later, at 2 a.m., the thugs attacked William Willard as he was walking at the corner of North Clark and Kinzie Streets, six blocks from the Alexandria Hotel. They beat Willard up and stole ten dollars.

As the bandits fled Willard made his way to the nearest police station at 115 West Chicago Street to report the crime. He was joined there by Robert Campion once Campion had recovered sufficiently from his own injuries. Ironically James Kane's home address was a few doors away at 131 West Chicago.

The police at Chicago Street immediately telephoned all the other stations warning them to be on the lookout for Campion's cab.
