After a series of bank robberies, the Dillinger Gang arrived in Tucson to hide out. On January 22, 1934, a fire started in the basement and spread up to the third floor, where the gang resided under aliases. After the desk clerk contacted them through the switchboard the gang escaped by aerial ladders. On the request of the gang, two firemen retrieved their luggage, identifying who they were. After being transferred to a jail in Crown Point, Indiana, Dillinger escaped again and was eventually shot down in Chicago, Illinois. Local Tucson architect Roy Place rebuilt the upper floor in the same style as the original. A historic plaque on the south entrance of the hotel bears Place's name so it is often believed to be of his original design.
