This is one of a half dozen police Haymarket investigation reports in the Chicago Historical Society's collection. When folded, the front page shows the name of the officer submitting the report, the date, and the signature of approval by Inspector John Bonfield, which appears to be stamped. Unfolded, the full report includes various particulars, signed by the person filing the report and his commanding officer.
The policeman who submitted this report is Michael H. Marks of the detective service, stationed in central headquarters in City Hall. His report is countersigned by Lieutenant John D. Shea. Shea served with Bonfield during the 1885 street railway strike, and he conducted several interrogations of Haymarket suspects. In his History of the Chicago Police, John J. Flinn states that Marks joined the force in 1884 and was detailed to the detective service at the beginning of February 1886. "He has, on many occasions," writes Flinn, "shown the possession of detective ability of a high order, but is too modest to have anything said about it."
Detective Marks reports that while searching on Wells and Madison Streets for a man named Fred Heller, he arrested the keeper and an inhabitant of one of Chicago's numerous gaming houses. The following day Marks reported the arrest of Heller. He states here that he was looking for Heller in order to get a lead on Rudolph Schnaubelt, brother-in-law of Michael Schwab and, in many people's minds, the likely bomb-thrower (see "The One that Got Away" entry in this section).
Other reports by different policemen deal with the surveillance of strikers, possible trouble at the McCormick's works, the search of a house on Dayton Street where numerous copies of Johann Most's anarchist newspaper Freiheit were found, and observation of a saloon on Clybourn Avenue "where anarchists congregate."
