On August 24, 1916 Officers Glenn Marshall and Phillip V. Neff responded to a call from a landlord who was being threatened by a delusional tenant. By the time the officers arrived, the tenant - a Dr. Fred Larkin - had broken through the landlord's door and was attempting to injure him. The officers pursued Larkin through the building, Larkin armed and firing two weapons until one gun was lost in the chase. Both officers were gravely wounded, Neff physically struggled with Larkin until they both lost consciousness. Marshall was shot numerous times, and died of his injuries that day. An autopsy on Larkin revealed that he had been high on a combination of morphine, heroin, and cocaine at the time of his attempted arrest.

Officer Marshall was survived by his wife.
