S3·E19 Log 165: Once a Cop

Malloy and Reed are on patrol, and find a homeless man stabbed. They take a retired policeman, Jack Donohoe (who lives nearby), in for questioning, but he is released when the real suspect is found. Donohoe later gets involved in a shootout with a robbery suspect. Other incidents include an aspiring actress from Missouri shooting up a phone booth at Union Station after being lured by a theatrical agent who promised a movie career and took her money, and then having her suitcase, containing a rattlesnake, stolen at the station.
