Sept. 21, 1902, Detective Wooldridge was placed in charge of the Get-Rich-Quick concerns with which Chicago was infested. He also had charge of the suppression of gambling at parks and other places of amusement, the inspection and supervision of picture exhibitions in penny arcades and museums, and the inspection and supervision of illustrated postal cards sold throughout the city for the purpose of preventing the exhibition, sale and circulation of vulgar and obscene pictures, the work of gathering evidence against and the suppression of dealers in "sure thing" gambling devices, viz., loaded dice, marked cards, roulette wheels, spindle faro layouts, card hold-outs, nickel slot machines and many other devices. Oct. 25, 1893, Detective Wooldridge had a narrow escape while trying to arrest Charles Sales, a desperate colored man, for committing a robbery at State and Harrison streets. Sales whipped out his gun and fired four shots at Wooldridge at short range; two of the shots passing harmlessly through his coat. Sales was arrested and given one year in the house of correction. RIDES TO STATION ON PRISONER'S BACK. June 6, 1894, Detective Wooldridge arrested Eugene Buchanan for committing a highway robbery at Polk and Clark streets. A few days prior he had held up and robbed Philip Schneider and kicked out one of his eyes. Buchanan was met in the alley between Clark street and Pacific avenue, where he resisted arrest and fought like a demon, using his hands, club and head. In the scuffle he ran his head between Wooldridge's legs and tried to throw him, but Wooldridge was to quick for him and fastened his legs around Buchanan's neck like a clam. Buchanan could not free himself. Wooldridge pulled his gun and placing it in the ear of Buchanan compelled him to carry him to the Harrison street police station on his shoulder. It was one of the most novel sights ever witnessed, and will be long remembered by those who saw it. Buchanan was convicted and sent to the penitentiary for three years. Upon his release he applied to Wooldridge to assist him in securing a position. Wooldridge took him to his home, fed him and secured employment for him with Nelson Morris & Co., where he remained three years. He afterwards committed a highway robbery in Washington Park and is now serving an indefinite term in the penitentiary. HANGS ON WINDOW SILL. May 16, 1895, Detective Wooldridge, accompanied by Officers Kern, O'Connor and Cameron, located Matt Kelly at 411 State street, who was wanted for a criminal assault. Kelly was a hold-up man, ex-convict and a notorious safe-blower, who several years prior to this shot two officers in St. Louis, Mo. Kelly was found behind locked doors on the second-floor and refused to open the doors. Detective Wooldridge went to the adjoining flat, opened a window and crawled along the ledge until he had reached Kelly's room; with a revolver in his mouth he pushed up the sash and was faced by Kelly and his wife.
