U.S. v. Corona-Gonzalez

Dist. Ct. erred in sentencing defendant to 240-month term of incarceration on drug distribution charge where said sentence was based on Dist. Ct.'s misperception that defendant had previously been removed from U.S and had illegally reentered U.S. for purpose of trafficking in drugs. New sentencing hearing was required where instant misperception played significant role in adjudication of defendant's sentence.
