The document is a legal memorandum from defendant Alfredo Barba, arguing for the severance of count three from a superseding indictment due to misjoinder and prejudicial joinder. Barba contends that the charges of drug trafficking and money laundering (counts one and two) are unrelated to the illegal re-entry charge (count three), thus risking jury confusion and prejudice. The memorandum highlights that the offenses do not share a common scheme, and joining them for trial undermines Barba's right to a fair trial.
