The Barker-Karpus Gang in the 1930s

Two of Ma Barker's sons tried the most extreme method imaginable to hide from the law that decided to undergo dangerous experimental surgery to change their faces. An ex-convict named Joseph P. Moran was in charge of the procedure, which involved looping elastic bands tightly around the gangsters' fingertips at the first joint and injecting cocaine into each of their fingers and thumbs. Dr. Moran performs other services for the gang, such as laundering some of the kidnap money through his Chicago practice. Alvin and Arthur Barker acting on Ma's orders gunned him down in July of 1934.
