Just after Ma and Fred's death in a shootout with the FBI on January 16, 1935, Karpis nearly met his own violent end when the FBI located him in Atlantic City, New Jersey. Karpis and Harry Campbell managed to shoot their way to an escape, though Karpis' eight-month-pregnant girlfriend Dolores Delaney was hit in the thigh by a wild shot fired by Campbell. She was captured along with Campbell's girl. Dolores gave birth to a son, who was adopted by Karpis' parents. Karpis and Campbell hid out with brothel-keeper Edith Barry for several months.
