Deafy Sweetfellow (possibly an alias) ran a bicycle theft ring in Dick Tracy's city. He had heavy eyelids and prominent lips. Deafy used a hearing aid and pretended to be deaf, but he actually had exceptionally good hearing. Deafy had his accomplice Johnny Naem recruit Junior Tracy to operate a bicycle parking lot on a piece of property that Deafy owned near Junior's school. Deafy then arranged for a number of the bicycles to be damaged, thus creating a market for his stolen bicycles. Junior discovered the plot and exposed Deafy, but was seriously injured in the process.
