Rule of Law:
Evidence of a prior crime is inadmissible under Federal Rule of Evidence 404(b) to prove identity through a unique modus operandi unless the prior act and the charged offense share characteristics that are so unusual and distinctive as to be like a signature, and are not merely generic to the type of crime committed.
Facts:
- In 1988, Gerald Carroll robbed a bank using a firearm and was subsequently convicted.
- Carroll was released from prison and began supervised release on September 6, 1996.
- On July 30, 1998, two men, including Gerald Carroll, robbed the St. Louis Community Credit Union.
- In both the 1988 robbery and the 1998 robbery, the perpetrator wore a nylon stocking mask, carried a firearm, and vaulted over the counter.
- Following the 1998 robbery, a witness saw the robbers flee in a Honda and alerted the police.
- Police officers initiated a high-speed pursuit of the Honda, which ended when the vehicle crashed.
- The car's two occupants fled on foot, and one of them, Carroll, engaged in a shootout with the pursuing officers.
- Police found Carroll hiding behind a dishwasher in a nearby alley and arrested him after he resisted.
Procedural Posture:
- The United States prosecuted Gerald Carroll in the United States District Court (trial court).
- During trial, the prosecution moved to introduce evidence of Carroll's 1988 armed robbery conviction under FRE 404(b).
- Over Carroll's objection, the District Court admitted the evidence for the purpose of showing plan, pattern, or identity.
- A jury convicted Carroll of armed robbery and a related firearms charge.
- The District Court sentenced Carroll to life in prison plus twenty years.
- Carroll appealed his conviction to the United States Court of Appeals for the Eighth Circuit.

Issue:
Does the admission of evidence of a defendant's prior, ten-year-old robbery conviction, which shares only generic characteristics with the charged robbery, violate Federal Rule of Evidence 404(b) when offered to prove identity?
Opinions:
Majority - Bowman, Circuit Judge
Yes, the admission of the prior conviction violates Federal Rule of Evidence 404(b). Evidence of a prior crime used to prove identity is only admissible if the pattern and characteristics of the crimes are so unusual and distinctive as to be like a signature. The court reasoned that the shared features of the two robberies—wearing a nylon stocking mask, carrying a gun, and vaulting the counter—are 'too common' and 'generic' to form a unique modus operandi that identifies Carroll. Furthermore, the ten-year gap between the crimes, despite Carroll's incarceration, weakens any inference of a signature plan. The evidence served only to show a propensity to commit robberies, which is expressly prohibited by Rule 404(b). However, the court concluded that this error was harmless due to the overwhelming independent evidence of Carroll's guilt, including positive identification by two police officers, the high-speed chase, the shootout, and Carroll's incriminating statement leading police to the gun used in the robbery.
Analysis:
This case refines the application of the modus operandi exception under FRE 404(b) for proving identity. It establishes a high bar for admissibility, requiring that the shared characteristics between the past and present crimes be 'sufficiently idiosyncratic' rather than 'garden variety' criminal acts. The decision serves as a caution to lower courts against admitting prior act evidence based on generic similarities, reinforcing the rule's core purpose of preventing convictions based on a defendant's character or criminal propensity. By emphasizing the distinctiveness of the acts and their temporal proximity, the ruling provides a clearer framework for analyzing such evidence and protects defendants from prejudice.
