The statute provides for a minimum five-year sentence to run consecutive to any other sentence involving the same transaction. The U.S. Sentencing Guidelines provide for an upward departure, at the discretion of the judge, to reflect the seriousness of the defendant’s prior criminal history or the seriousness of the underlying offense.
