Walter Walsh's Olympic participation in 1948 seems like a footnote to a life of experiences known by few men. Born in New Jersey, Walsh graduated from Rutgers Law School and then in 1934 joined the FBI. A year later he was on the stakeout team in Chicago that apprehended Doc Barker, one of the most wanted criminals in the United States. Acting on a tip that same year, he also discovered the body of Chicago gangster Baby Face Nelson. Two years later he was involved in a shoot-out in Bangor, Maine with Al Brady, who was at the time Public Enemy #1 and who was killed during the shoot-out.
