Pretty Boy Floyd
What is known for sure is that Floyd and his sidekick, Adam Richetti, started driving from Springfield toward Kansas City early on the morning of June 16 along Highway 13. South of Bolivar, their car broke down, and a passing farmer towed them into Bitzer's garage in Bolivar. Richetti had formerly lived in Bolivar, and his brother still worked at the garage. While the mechanics worked on the disabled vehicle, Sheriff Jack Killingsworth dropped by the garage. Although he was simply paying a friendly visit, Richetti grew suspicious, pulled a machine gun from the floorboard of the car, and threatened to start shooting. A customer pulled into the garage and, seeing the situation, made his escape to a drugstore across the street, where he called the cops.
As the situation started to get out of hand, Floyd took over inside the garage, ordering the hostages to stand against a wall and instructing Richetti to go find a getaway car. Richetti commandeered his brother's car and brought it back to the garage, where he and Floyd transferred guns and other items from the disabled vehicle to the getaway car. Floyd forced Killingsworth into the backseat of the car as a hostage, and it sped away with Richetti at the wheel. Officers gave chase and at one point got very close to the fugitives, but the sheriff, at the point of a gun, waved for the lawmen to back off.
In the late morning, the gangsters exchanged vehicles by waving down a passing motorist and then continued their trip toward KC with the motorist as an additional hostage. Late that night, they let both hostages loose in Kansas City, and early the next morning the Kansas City Massacre occurred.
The FBI identified the ringleader of the gang who pulled the crime as Verne Miller, and Floyd and Richetti were identified as his two sidekicks. Miller was killed in a gang-style murder a few months later. Floyd was killed by police a year or so later, and Richetti was captured, convicted for his role in the crime, and sentenced to death.
