That is a complex question that depends on whether a defendant is convicted, the type of offense, prior criminal history, and a defendant's unique characteristics.
Sentencing in federal court is controlled by the Sentencing Reform Act of 1984. Under 18 USC § 3553(a), there are many factors that go into sentencing in federal court, including the nature of the offense, the characteristics of the offender, the need to pay restitution, and access to medical and other treatment.
One factor that the court must consider is the Federal Sentencing Guidelines. Calculation of the guidelines can provide one rough estimate of a defendant’s sentence before a plea or trial. The defendant’s attorney will be able to give more details about the defendant’s potential sentence.
