Sazenski (D), Izquierdo (D2) and others were prosecuted for drug offenses. They were alleged to have shipped marijuana from Miami to Minnesota.

The district court admitted into evidence an envelope addressed to D and Carlos Almaden to show that Carlos lived with D. D contends that the letter is hearsay.
