United States v. Gonzalez, 625 F.3d 824

Gonzalez was convicted by a jury of conspiracy to possess with intent to distribute more than 1,000 kilograms of marijuana and possession with intent to distribute the same.
The Government filed a §851 information seeking enhanced punishment based on a 1988 marijuana offense and a 1997 cocaine offense.
Under §841(b)(1)(A), two or more prior felony drug offenses carry a mandatory life sentence.
Gonzalez denied both prior convictions in writing and at sentencing, triggering a §851(c)(1) hearing and a government burden to prove the prior convictions beyond a reasonable doubt.
The Government introduced two prior judgments showing the 1988 and 1997 convictions and the offender’s name and matching Social Security numbers; a probation officer corroborated the 1997 conviction, and the district court overruled Gonzalez’s objections and sentenced him to concurrent life terms.
Gonzalez challenges only the use of the 1988 conviction for sentencing enhancement.
