A few years later, Speck's religious, teetotaler mother fell in love with a traveling insurance salesman from Texas, Carl August Rudolph Lindberg, whom she met on a train trip to Chicago. The hard-drinking, peg-legged Lindberg, with a 25-year Criminal record that started with forgery and included several arrests for drunk driving, was the opposite of Speck's sober, hardworking father. Speck's mother married Lindberg on May 10, 1950, in Palo Pinto, Texas. Speck and his younger sister Carolyn stayed with their married sister Sara Thornton in Monmouth for a few months so Speck could finish second grade, before joining their mother and Lindberg in rural Santo, Texas, 40 miles west of Fort Worth, Texas, where Speck attended third grade.
