Prendergast rang the doorbell of Harrison's home. Harrison's
maid, Mary Hanson, answered the door, and requested that Prendergast return in a half-hour. When Prendergast returned, she asked him to wait in the hall. Hanson went to retrieve the mayor. After shooting the mayor, Prendergast ran out of the residence through its front door. Harrison's
coachman, Paul Elliason Risberg, having heard the gunshots from the level of the House below, had quickly run up the stairs to the entrance level with a
handgun. Noticing Risberg emerging into the front hall, the fleeing Prendergast shot into the front hall. Risberg returned fire. Neither were wounded in this exchange. The noise of the commotion attracted the Harrisons' neighbor William Chalmers (the president of the
Allis-Chalmers steel company) to quickly run into the residence. Household servants also ran to Mayor Harrison's side. Harrison had pulled himself through the dining room and into a butler's pantry that led to the kitchen before collapsing. William Preston Harrison, who was upstairs, signaled for help by activating an emergency signal in the upstairs, then ran outside to ask a passing bicyclist to get the family doctor. When he came to his father's side William Preston Harrison asked, "father's not hurt, is he?" to which the mayor responded, "Yes. I am shot. I will die." Mayor Harrison was bleeding from his mouth and remained conscious for roughly twelve minutes. Chamlers and William Preston Harrison carried the wounded mayor to a
sofa. Chalmers placed his folded coat underneath Harrison's head. He argued that Harrison was wrong in his belief that he had been shot in his
heart. Harrison responded, "I tell you I am, this is death." Chalmers would later remark, "he died angry because I didn't believe him. Even in death, he is emphatic and imperious." As doctors and police arrived, Harrison remarked, "doctors are no good now," as he was nearing death. His last words were reported to be, "Give me water. Where is Annie," referring to his fiancé Annie Howard, who had been visiting the nearby home of Harrison's son
Carter Harrison IV at the time of the assassination. Howard arrived around the time that the mayor succumbed to internal
hemorrhaging. His death came approximately twenty or twenty-three minutes after he was shot. ==Prendergast's surrender to police==
