Robert Cosgrove Greenlease Jr. (February 3, 1947 – September 28, 1953) was a six-year-old from Kansas City, Missouri, United States, who was the victim of a kidnapping and homicide on September 28, 1953. His father, Robert Cosgrove Greenlease Sr., was a multi-millionaire auto dealer, and the demanded ransom payment was the largest in American history at the time. Greenlease Jr.'s kidnappers, Carl Hall and Bonnie Heady, had no intention of returning him to his family, the child having been murdered before the ransom demand was even issued. Both perpetrators were sentenced to death and executed in Missouri's gas chamber in December 1953. Heady was the third woman ever to be executed by U.S. federal authorities.

Abduction and murder In September 1953, Carl Hall (34) and Bonnie Heady (41), kidnapped Bobby from Notre Dame de Sion, a Catholic pre-school located in Kansas City, Missouri. The kidnappers were drug-addicted alcoholics then living together in nearby St. Joseph. In the early 1930s, Hall had attended Kemper Military School in Boonville with Paul Robert Greenlease, Bobby's adopted older brother. Hall had planned for years to victimize his former classmate's wealthy family. Heady visited Bobby's school and persuaded a nun, Sister Morand, that she was his aunt, telling her that his mother had suffered a heart attack and was in St. Mary's Hospital.
