Whether evidence of the March 1992 warehouse fire was admissible under Federal Rule of Evidence 404(b) to show a common scheme or plan rather than criminal propensity.
Holding
Yes. The district court abused its discretion by excluding the evidence; the 1992 fire was specially relevant to a common plan to burn the same warehouse for insurance proceeds and was not barred by Rule 403.
Reasoning
Before admitting other-act evidence, the court had to determine whether a jury could reasonably find by a preponderance of the evidence that the earlier act occurred and that DeCicco committed it. Although the evidence tying him to the 1992 arson was circumstantial, it was sufficient: the fire occurred shortly before cancellation of his insurance, while he faced foreclosure and tax pressure; he was the policy beneficiary; and the later fires employed a similar method. The jury, rather than the court, could weigh that combined evidence.
The 1992 fire had a non-propensity purpose because it supported the government's theory of a continuing common scheme to destroy the Heard Street warehouse and obtain insurance proceeds. The three-year interval did not make the incident too remote. The government plausibly argued that DeCicco had to wait until the prior policy cancellation no longer had to be disclosed to a new insurer, and First Circuit precedent had allowed other-act evidence separated by even longer periods.
The incidents also strongly resembled each other. The 1992 fire and the final 1995 fire were intentionally set at the same building by pouring accelerant at the base of support pillars. Because the earlier fire could be understood as an unsuccessful step in the eventual destruction of the same insured property, it led in progression to the charged conduct rather than merely showing a general tendency toward wrongdoing.
The evidence was prejudicial, but not unfairly so within the meaning of Rule 403. Its substantial probative value on the alleged common scheme outweighed the manageable risk that jurors would misuse it as propensity evidence, particularly if the jury received proper limiting instructions. The district court therefore erred in excluding it without undertaking the required analysis.
