Adam Richetti

Despite the fact that there was nothing to link Richetti and Floyd to the shooting, the FBI identified them along with Miller as the triggermen on October 10, 1934. At the time of the announcement, the two were still living in Buffalo with their girlfriends. Floyd, by this time, had been elevated to "public enemy #1" for his alleged role in the Kansas City Massacre.

Richetti was indicted for obstruction of justice on November 6, 1934, however that charge was held in abeyance when he was officially charged with murder by Missouri state officials for his alleged role in the Kansas City Massacre. During this time, Richetti was represented by Attorney Hugo Chestosky who fought against Richetti's extradition to Missouri. Chestosky doubted Richetti's role in the Kansas City Massacre based on his belief that the suspect had no involvement in the death of the officers. His trial began on June 13, 1935, during which time a number of eyewitnesses identified him and Floyd despite these witnesses having previously identified other suspects or had been unable to identify anyone at the time of the shooting two years earlier. Three days later, Richetti was found guilty of the murder of police officer Frank Hermanson and sentenced to death. His legal team appealed the court's decision but ultimately failed to get a new trial. Richetti was originally to be sent to the gallows but was instead executed in Missouri's newly constructed gas chamber on October 7, 1938.

He finally reappeared on January 12, 1933, to rob a bank in Ash Grove, Missouri of $3,000. His partners in the heist were Edgar Dunbar and Aussie Elliott with whom he hid at his brother's home in Bolivar, Missouri. Sometime prior to this, Richetti met Pretty Boy Floyd who eventually became one of his closest confidants. The two became partners and, despite Richetti's worsening alcoholism, accompanied Floyd on a crime spree during the summer of 1933. They stole a car in Castle, Oklahoma on June 8 and together stole $1,638 from a bank in Mexico, Missouri six days later. That same afternoon, two police officers were killed near Columbia for which Richetti and Floyd were wrongly accused.

Adam "Eddie" Richetti (August 5, 1909-October 7, 1938) was an American criminal and Depression-era bank robber. He was associated with Aussie Elliott and later Pretty Boy Floyd in the early-1930s, both he and Floyd later being implicated in the Kansas City Massacre in 1933.

Adam Richetti was born in Strawn, Texas on August 5, 1909, and moved with his family to Lehigh, Oklahoma three years later. He had an older brother Joseph and a younger sister Eva. Richetti, although he began drinking heavily at 14, was apparently uninvolved in criminal activity until his arrest for robbery in Crown Point, Indiana on August 7, 1928, two days after his 19th birthday. He was convicted and sentenced to serve 1 to 10 years at the Pendleton state reformatory, remaining there for two years, and paroled on October 2, 1930.
