Background

Defendant Arnaldo Irizarry-Irizarry, a lawyer, served as a legal advisor to the Municipality of Mayagüez and its enterprise, Mayagüez Economic Development, Inc. A scheme was devised to divert nine million dollars intended for trauma center renovations into private investment accounts. Irizarry and co-conspirators created shell companies to receive payments for non-existent services and attempted to conceal the diversion from municipal auditors. He was convicted of conspiracy to commit wire fraud, wire fraud, and money laundering.

The court’s reasoning

The court analyzed the sufficiency of the evidence for the conspiracy charge by examining common goal, interdependence, and overlap. It found that Irizarry knew his financial success depended on the fraud scheme’s continued existence, satisfying the interdependence factor. The court determined that the pervasive involvement of a central conspirator, García, who coordinated the scheme and interactions with Irizarry, satisfied the overlap factor. Regarding the sentence reduction, the court held it lacked jurisdiction because the defendant did not file a notice of appeal from the district court’s denial of his motion.

Irizarry’s sufficiency arguments as to the substantive counts — wire fraud and money laundering — derive from his sufficiency challenge to the conspiracy count.

What it means going forward

The ruling reinforces that appellate courts lack jurisdiction over sentencing reduction denials if a separate notice of appeal is not filed, and it clarifies that conspiracy overlap can be proven through the actions of a central hub figure even if a defendant does not know all other participants.
