Mamma was a 300 pound giant woman who was a villain in the Dick Tracy comic strip.
She was the common law wife of a gang boss Jerome Trohs [Short spelled backward]. She was devoted to him until he escaped and let her be caught by the police. She escaped from prison and made her way West of Dick Tracy City until she tracked him to a cabin resort he had swindled a couple out of and killed him.
Tracy was unable to prevent Trohs murder but he did manage to arrest her...with the help of his right hand which she had helped break weeks before.
