United States v. Monteiro — 1st Cir. (argued September 10, 2026)
The First Circuit hears Robert Monteiro's appeal from a cocaine-conspiracy conviction. Prosecutors said Patrick Joseph's organization mailed cocaine from Puerto Rico to Massachusetts, often hidden in air fryers or cash boxes. At trial, a cooperating witness and surveillance tied Monteiro to Joseph, package pickups, and a suspected drug exchange. After a jury convicted Monteiro, he appealed. He now argues that officers should not have been allowed to opine that unopened packages contained cocaine, and that the remaining evidence did not show he knowingly joined the conspiracy.
