Floyd and Richetti were allegedly Miller's accomplices. Factors weighing against them included their apparent presence in Kansas City at the time, eyewitness identifications (which have been contested), Richetti's fingerprint recovered from a beer bottle at Miller's hideout, an underworld account naming Floyd and Richetti as the gunmen, and Hoover's firm advocacy of their guilt. Fellow bank robber Alvin Karpis claimed that Floyd confessed involvement. On the other side of the issue, the bandit alleged to have been Floyd was supposed to have been wounded by a gunshot to the shoulder in the attack, and Floyd's body showed no sign of this injury when examined later. The underworld account identifying Floyd and Richetti as the killers was offset by equally unreliable underworld accounts proclaiming their innocence. The Floyd family has maintained that Floyd admitted to many other crimes but vehemently denied involvement in this one, as did Richetti.
