On November 15, 1913, Deputy City Marshal Maurice W. Halloran was shot and killed while questioning two suspicious men who had entered a liquor store at 2000 East Vernon Avenue.

Deputy Marshal Halloran was already inside the establishment when the two men entered and approached the store counter to purchase alcohol. While waiting for the store clerk, one of the subjects vandalized the wood counter with a pocket knife. Deputy Marshal Halloran confronted the man about the vandalism, prompting the two men to curse at him and then leave. Attempting to further address the subjects, Deputy Marshal Halloran followed them outside and, without warning, one of the men produced a handgun and shot Halloran multiple times. Deputy Marshal Halloran later died at the hospital. Both subjects fled the scene but were ultimately arrested and charged with the murder of a peace officer. Both men were convicted and sentenced to life in prison.

Deputy Marshal Halloran was survived by his parents, three brothers, and two sisters.
