Rosa Buckstahlen and Ida Bjornstad, servants in the Chicago mansion of Amos J. Snell, were awakened at 2:00 the morning of February 8, 1888, by the sound of a gunshot from the floor below. They heard someone shout “Get out! Get out of here!” followed by more gunshots, then silence. Thinking that all was well—or more likely, too frightened to do anything else—the girls went back to sleep.
Five hours later, Mr. Snell’s coachman, Henry Winklebook, entered the house to attend the furnace fires and found evidence of a break-in. Snell’s basement office was strewn with scattered papers, his safe was open, and a broken strongbox lay on the floor. Winklebook hurried upstairs to inform his employer and found his lifeless body lying in a pool of blood in the hallway.
