OPINION
Introduction
A jury convicted Mark Thornton of conspiracy to possess with intent to distribute cocaine and cocaine base (Count 1), possession with intent to distribute cocaine (Count 3), and possession of a firearm in furtherance of a drug trafficking conspiracy (Count 5). Thornton, who had three prior drug convictions, was sentenced to life imprisonment on Count 1 pursuant to a mandatory minimum sentence, as well as consecutive sentences of 264 months imprisonment on Count 3 and 60 months imprisonment on Count 5. Thornton appeals his conviction and sentence, asserting a number of procedural and constitutional errors. We affirm.
Background
On October 12, 2005, law enforcement officers executed a search warrant for a house on Eastview Avenue in Dayton, Ohio. The warrant was based on information from confidential informants. The officers seized approximately 800 grams of *376 powdered cocaine, numerous wrappers used to package kilogram quantities of cocaine, drug-related tools, and several firearms. The house was rented by Nirvana Martin, and Thornton was present in the house when the search occurred. Both Martin and Thornton were eventually arrested and charged with various drug offenses. Martin pled guilty; as part of his plea agreement, he agreed to testify against Thornton.
At Thornton’s trial, an individual named George Cash testified that he introduced Thornton and Martin to a Mexican drug supplier in Dayton during the summer of 2005. Martin testified that he and Thornton pooled their money to purchase a kilogram or more of cocaine from this Mexican supplier every day for several months during the summer and fall of 2005. The two would then divide the cocaine at one of the drug houses rented by Martin, including the house on Eastview Avenue, and re-sell their respective portions. Martin also testified that he and Thornton carried firearms during their drug transactions.
Discussion
Jury Instruction Conference
Thornton first argues that the district court erred by excluding him from the jury instruction conference in violation of Federal Criminal Rule 43(a)(2)’s requirement that a criminal defendant be present at “every trial stage.” The Government contends that a jury instruction conference falls within the exception of Rule 43(b)(3) for a “conference or hearing on a question of law,” and therefore Thornton’s presence was not required.
All circuits that have directly addressed this issue hold that jury instruction conferences do fall within the Rule 43(b)(3) exception.
See, e.g., United States v. Rivera,
However, we need not reach the merits of this issue here because Thornton has presented no argument that the conference resulted in erroneous jury instructions, and we find no prejudice from his exclusion. The conference was held on the record, and Thornton’s attorney was present to discuss factual and legal issues relating to the instructions. There is no indication that his attorney was not fully capable of representing Thornton’s interests in this regard, or that his attorney could not consult with Thornton if needed. The jury was not present, thus Thornton could not have been prejudiced in that regard. Accordingly, even if exclusion of Thornton from the conference was error, such error was harmless.
See United States v. Harris,
Plea Agreement of Codefendant
Thornton next argues the Government improperly questioned his codefendant, Nirvana Martin, about the details of Martin’s plea agreement. Defendant did not object at trial to this line of questioning, so we review the admission of such testimony for plain error.
See United States v. Zidell,
On direct examination, the Government questioned Martin about the charge to which he pled guilty, the statutory penalties and sentencing guideline range he confronted, the reason for his agreement to testify at trial, and the charges which the Government had agreed to dismiss as a result of his cooperation. The Government then questioned Martin directly about his relationship with Thornton. Several pages of Martin’s plea agreement were published to the jury during the Government’s direct examination. However, the district court did not admit the agreement itself as evidence.
Defense counsel did not object to the Government’s questioning or publication of the plea agreement, nor did defense counsel request a limiting instruction on the permissible use of the plea agreement. Defense counsel’s sole objection was to a question asking whether Martin had an understanding where the guidelines placed him in the permissible statutory range of ten years to life. On cross-examination, defense counsel also questioned Martin regarding the plea agreement, including his potential sentence. During closing argument, the Government never mentioned the plea agreement, and defense counsel mentioned it only briefly in an attempt to impugn Martin’s credibility. The district court instructed the jury that “[e]vidence of ... prior convictions was brought to your attention only as one way of helping you decide how believable [the witnesses’] testimony was. Do not use the evidence of the prior convictions for any other purpose.”
Thornton claims two forms of prejudice from the prosecutor’s questioning of Martin. First, he argues the jury might have used Martin’s guilty plea — an admission of guilt already “accepted by the District Court” — as direct evidence of Thornton’s own guilt. Second, Thornton argues that Martin’s testimony about his own sentence may have confused the jury about the sentence Thornton was facing. These arguments are foreclosed by circuit precedent.
We have previously ruled that “a guilty plea of a codefendant may not be received as substantive evidence of a codefendant’s guilt, but may properly be considered as evidence of a witness’ credibility.”
United States v. Christian,
Moreover, although “[a] guilty plea entered by a codefendant can be especially prejudicial if the plea is made in connection with a conspiracy to which the remaining defendants are charged, ... much of this potential for prejudice is negated when the pleading codefendant ... testifies regarding the specific facts underlying the crimes in issue.”
Christian,
As to the risk of potential confusion about the sentence Thornton was facing, some discussion of a codefendant’s potential sentence is inevitable if the Government is allowed to explore a codefendant’s motivation for testifying. Furthermore, in this case, defense counsel also inquired into Martin’s potential sentence, so Thornton cannot legitimately claim this information prejudiced him.
In sum, Martin’s testimony about his plea agreement was permissible in order to allow the jury to fully assess his credibility. The Government did not cite the plea agreement for any improper purpose during closing argument.
See United States v. Carson,
Life Sentence
Thornton next argues the district court’s sentence of life imprisonment on Count 1 is grossly disproportionate to the crime committed and is thus unconstitutional under the Eighth Amendment. Thornton’s sentence was imposed pursuant to 21 U.S.C. § 841(b)(1)(A), which mandates life imprisonment when a defendant has two or more prior felony drug convictions. 1 Thornton, who has three prior felony drug convictions, does not contest that he meets the statutory criteria. Rather, he challenges the constitutionality of the sentence as applied to his particular circumstances.
Thornton’s argument is foreclosed by
United States v. Hill,
*379
Following
Hill,
this Circuit has continued to reject Eighth Amendment challenges to mandatory life sentences in repeat-offender drug cases.
See, e.g., United States v. Odeneal,
The circumstances of Thornton’s case (including the 72 kilograms of cocaine) are in line with these cited cases. Accordingly, there is no reason to depart from our settled precedent, and we conclude that Thornton’s sentence was not unconstitutional.
Plea Negotiations
In a supplemental brief filed
pro se,
Thornton next claims the district court violated Federal Criminal Rule 11(c)(1) by participating in plea negotiations.
2
However, because Thornton did not plead guilty and was convicted by a jury, he must show “actual prejudice” in order to be entitled to a new trial.
See United States v. Elguezabal,
Search Warrant
In his pro se brief, Thornton also challenges the district court’s pretrial ruling that Thornton had no Fourth Amendment standing to challenge the validity of the search of the Eastview Avenue house. Much of the physical evidence supporting the Government’s case was seized pursuant to that warrant. Prior to trial, Thornton moved to suppress the seized evidence, arguing there was no probable cause to issue the warrant.
Following a hearing (at which Thornton offered no evidence related to Fourth Amendment standing), the district court granted Thornton’s suppression motion as to cell phones and cash seized from his person, but denied the motion as to the drugs and other objects seized from the house. The district court provided two grounds for denying Thornton’s motion as to the evidence found in the house. First, Thornton had no reasonable expectation of privacy in the drug house and therefore no Fourth Amendment standing to challenge the validity of the warrant. He was not *380 the owner or lessee of the house, and there was no evidence Thornton or anyone else lived at the house. Rather, the house was being used as a commercial drug distribution center. Second, even if Thornton had standing, the search warrant was supported by probable cause, because it was based on detailed information from an informant that was confirmed by law enforcement officers with recent surveillance of the house.
We decline to address Thornton’s argument because he challenges only the district court’s conclusion that he lacked standing to challenge the warrant; he does not address the district court’s alternative holding that the warrant was supported by probable cause. Issues raised in the district court, but not on appeal, are considered abandoned and not renewable on appeal.
United States v. McPhearson,
Sufficiency of Evidence
Finally, Thornton argues in his
pro se
brief there was insufficient evidence to prove his guilt on any count. This argument lacks merit. When reviewing sufficiency of the evidence, this Court must determine “whether, after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
United States v. Blakeney,
Count 1 — Conspiracy to Distribute in Excess of Five Kilograms of Cocaine
In order to prove a drug conspiracy, the Government must prove “(1) that an agreement to violate the drug laws existed; and (2) that each conspirator knew of, intended to join, and participated in the conspiracy.”
United States v. Forrest,
Count 3 — Possession with Intent to Distribute 500 grams of Cocaine
To prove possession with intent to distribute, the Government must prove that Thornton exercised actual or constructive possession over the controlled substance and that he intended to distribute that substance. 21 U.S.C. § 841(a)(1). At trial, the Government presented evidence that law enforcement officers executing the search warrant found a shoe box containing cocaine upstairs in the house; that the cocaine weighed more than 500 grams; that the box belonged to Thornton; and that Thornton often stored in such a manner the cocaine he intended to sell. This is sufficient evidence for a *381 rational jury to conclude that Thornton possessed and intended to distribute the cocaine.
Count 5 — Possession of a Firearm in Furtherance of a Drug Trafficking Crime.
To prove possession of a firearm in furtherance of a drug trafficking crime, the Government must prove (1) Thornton committed a drug trafficking crime; (2) Thornton knowingly possessed a firearm; and (3) the possession of the firearm was in furtherance of this drug trafficking crime. See 18 U.S.C. § 924(c). Law enforcement officers seized numerous firearms during the raid on the drug house used by Martin and Thornton. In addition, Martin testified that he and Thornton carried firearms to protect themselves in the course of dealing with their suppliers. This is sufficient evidence for a rational jury to conclude that Thornton possessed a firearm in furtherance of a drug trafficking crime.
Conclusion
For these reasons, we AFFIRM Thornton’s conviction and sentence.
