PER CURIAM:
Following a bench trial, Antowan Thorne was convicted of the lesser-included charge of conspiracy to distribute 100 grams or more of heroin, in violation of 21 U.S.C. §§ 841(a)(1), 846 (2012). The district court sentenced Thorne to 300 months' imprisonment, which was in the middle of his Sentencing Guidelines range of 262-327 months. The calculation of this range was driven by Thorne's career offender designation.
On appeal, Thorne raises four issues for our consideration. He first challenges the sufficiency of the Government's evidence underlying his conviction and takes issue with the district court's decision to credit the cooperating witness's testimony. Thorne's next three issues relate to the computation of his Guidelines range. Specifically, Thorne asserts that one of his career offender predicates was improperly counted and that the district court erred in enhancing his base offense level for possessing a firearm and obstructing justice. For the reasons that follow, we reject these arguments and affirm the judgment.
Thorne first contends that the district court erred in denying his Fed. R. Crim. P. 29 motions during and at the conclusion of trial. We review de novo the denial of a Rule 29 motion for a judgment of acquittal.
To convict Thorne of conspiracy to distribute heroin, the Government had to prove the following essential elements: "(1) an agreement between two or more persons to engage in conduct that violates a federal drug law; (2) the defendant's knowledge of the conspiracy; and (3) the defendant's knowing and voluntary participation in the conspiracy."
With these standards in mind, we conclude that the Government's evidence was more than sufficient to support Thorne's conviction. The cooperating witness testified that, during the time period alleged in the indictment, the witness and Thorne worked together to sell Thorne's heroin to a broader array of customers. Thorne was the witness's primary source for heroin, and the witness sold between 100 and 150 grams of heroin obtained from Thorne. Their relationship was based on the common goal of selling more drugs and thus making more money.
Thorne nonetheless contends that the Government failed to demonstrate a conspiracy because there was no direct evidence of an agreement between Thorne and any co-conspirator; none of the purchasers further sold the heroin they obtained from Thorne; and there was no testimony establishing profit-sharing. Thorne contends that the witness was, at the most, simply another customer of Thorne's.
Thorne's arguments fail on this record. Individuals involved in drug trafficking ventures do not memorialize their agreements in writing, and we have long recognized that, "[g]iven the `clandestine and covert' nature of conspiracies, the government can prove the existence of a conspiracy by circumstantial evidence alone."
Thorne's attempts to undermine the witness's credibility likewise are unsuccessful. The district court, sitting as the trier-of-fact, was in the best position to weigh the witness's credibility and demeanor, and acted well within its bounds in choosing to credit the witness's testimony.
Thorne's primary sentencing argument is that the district court committed reversible procedural error in its application of the modified categorical approach in determining his career offender status. For the reasons that follow, we find any error in this regard to be harmless and thus affirm Thorne's career offender designation.
We review any criminal sentence, "whether inside, just outside, or significantly outside the Guidelines range," for procedural and substantive reasonableness,
A defendant is a career offender if he was at least 18 years old at the time of the instant offense, the instant offense is a drug felony or crime of violence, and the defendant has at least two prior felony convictions for drug offenses or crimes of violence. USSG § 4B1.1(a). A prior conviction qualifies as a "crime of violence" if the offense is punishable by more than one year of imprisonment and, as relevant to this case, "has as an element the use, attempted use, or threatened use of physical force against the person of another[.]" USSG § 4B1.2(a)(1). This court reviews de novo the district court's conclusion that a prior conviction qualifies as a crime of violence.
Thorne only contests the viability of his second career offender predicate, to wit: Thorne's 2008 guilty plea, in the Superior Court for the District of Columbia, to conspiracy to obstruct justice, and resulting 36-month sentence. Thorne pled guilty to violating D.C. Code § 22-722(a)(2)(A), which provides, in relevant part:
In his objection to the use of this predicate, Thorne argued that this statute of conviction was divisible, under
The district court first rejected this argument based on the factual proffer. But the court went on to buttress this conclusion by citing the magistrate judge's report and recommendation, in Thorne's unrelated supervised release revocation proceeding in another federal district court, in which the magistrate judge recommended finding that this conviction qualified as a crime of violence under the modified categorical approach.
On appeal, Thorne claims the district court committed reversible procedural error in relying on the magistrate judge's recommendation to support its analysis. As we have explained, the modified categorical approach:
However, this error is rendered harmless by the fact that the district court announced a perfectly sound basis for the same finding immediately prior to noting its consideration of the magistrate judge's report: that the factual proffer accompanying the plea agreement established that Thorne's conviction was for a crime of violence. Indeed, the agreed-upon factual proffer clearly established that the threatened use of physical force against another was an element of Thorne's conviction under D.C. Code § 22-722(a)(2)(A) — even if that threat was not directly communicated to the intended victim.
Significantly, Thorne does not challenge the general propriety of the district court's utilization of the modified categorical approach or reliance on this
Our disposition of this issue effectively moots Thorne's challenges to the two-level firearm enhancement and the two-level obstruction of justice adjustment. Because the offense level established under the career offender Guideline was more than the offense level calculated using the Guidelines for the drug offense including any specific offense characteristic or adjustment,
For these reasons, we affirm the criminal judgment. We deny Thorne's motion to file a pro se supplemental brief in this counseled appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
