The criminal known as "Short" Circuit (real name unrevealed) was a little person, and an established jewel thief. He had hair that was short and light on the sides, but dark and spiky on top.
Circuit was observed by Dick Tracy and Sam Catchem entering a high-society event, but he could not be arrested due to lack of evidence. Circuit arranged for a power outage, during which he stole money and several valuable pieces of jewelty.
Circuit attempted to escape, but his poorly-maintained car made it easy for Tracy and Catchem to apprehend him.
- "Short" Circuit appeared in a print ad that Chester Gould produced for Ford Autolite auto parts in 1966. He has not appeared in the actual Dick Tracy comic strip.
