Officer Albert Siko succumbed to wounds received two days earlier while attempting to arrest a robbery suspect.

On April 29, 1934, Officer Siko had just gotten off duty and was waiting for a streetcar at Fourth and Delmar when a citizen alerted him to a streetcar robbery taking place one block away. Officer Siko rushed to the scene and observed the suspect fleeing to an alley just north of Franklin. As he chased the suspect the man turned and shot Officer Siko under the left eye. The man then shot Officer Siko three more times as he lay on the ground. After the man fled Officer Siko was able to crawl 50 feet to a call box and summon help.

A description of the robber led to the arrest of a suspect, Louis DeMore, a 42 year-old cab driver from Chicago, at the Rector Hotel at 603 Walnut. DeMore was taken to the hospital where Officer Siko identified DeMore as the shooter. Officer Siko died on May 1, 1934 at 4:45 am. DeMore was also identified as the robbery suspect by the operator of the street car, Thomas E. Fisher. The suspect was convicted of murder and sentenced to life in prison. He told prison officials that even though Officer Siko identified him that he was innocent. He said he admitted to the shooting because police told him that he would hang if he did not. A few weeks later a man, George Couch, was arrested with Officer Siko's service revolver in his pocket. He admitted killing Officer Siko, was convicted of his murder, and sentenced to life in prison on October 13, 1934. The other suspect, DeMore, was pardoned by Governor Park and was released.

Officer Siko was assigned to the Fourth District. He was survived by his wife, Martha, and two small sons. Because his death was in the line of duty his family received his salary of $165 a month for a year and $8,000 from the police pension fund. Interred: Jefferson Barracks National Cemetery.
