Patrolman Cavanaugh succumbed to gunshot wounds received the previous day after attempting to stop a robbery on East 21st Street. He was off duty and eating with his wife at a local tavern when a man entered and began robbing the establishment. Patrolman Cavanaugh drew his weapon and fired on the suspect, who then fled on foot. Patrolman Cavanaugh gave chase and in a running shootout was mortally wounded. The suspect was apprehended several days later.
The 32-year-old suspect was convicted of first degree murder and was the first person to be put to death in Missouri's new gas chamber on March 4, 1938.
