On March 17, 1954, at 9:40 p.m., 43 year old Louis Dulisse was riding as a Reserve Officer with Sgt. H. D. Williams – one of 35 sworn members of the department. The partners were sent to the Casa Blanca Hotel where two suspects were committing a robbery while a third waited in the getaway car. Williams entered the hotel leaving Dulisse to wait for backups. When additional officers arrived, Dulisse twice gave up his cover to warn them and to help Williams who had been taken hostage. The suspect who had Williams, began firing at Dulisse who could not return fire for fear he would hit his partner. Officer Dulisse was killed at the scene. The suspects were all taken into custody.
