Robert George Head, Jr., appeals from his conviction and sentence on two counts of aggravated assault, violations of 18 U.S.C. §§ 2, 113(a)(3), 1151, and 1153(a), and one count of brandishing a firearm during a crime of violence, a violation of 18 U.S.C. §§ 2 and 924(c)(l)(A)(ii). We affirm.
I.
Early on the morning of January 19, 2002, Head was smoking crack cocaine at the home of his then-girlfriend, Patricia Mountain. Also present and smoking crack cocaine were Kevin Boland, Alejandro Garcia, and Alana Brown, Head’s daughter. At some point, Head and Brown departed. Sometime thereafter, Garcia and Mountain departed in Garcia’s car. Head and Brown met up with Jeffrey Dolson and Arlen Rice, and the four of them, riding in Head’s truck, encountered Garcia’s car. Head began following Garcia around the reservation and at one point rammed Garcia’s car with his truck and told Garcia that he was going to kill him. Head and the others in his truck then returned to Mountain’s residence, where Head kicked in the door. He approached Boland and held a pistol to his head, demanding money and drugs. Head, Dolson, and Brown then assaulted Boland and departed. Garcia eventually returned to Mountain’s residence and discovered the injured Boland. Shortly thereafter, Head and others returned, and Garcia and Bo-land fled on foot. Head chased and caught Garcia and then assaulted him. The assault ended when a police officer arrived on the scene.
Head was arrested on tribal charges by the Red Lake Tribal Police Department later that morning. He was questioned by F.B.I. Special Agent John Egelhof at the Red Lake Tribal Jail. Agent Egelhof stated that he wanted to talk with Head about what had occurred earlier that morning. After informing Head that he had not been charged with a federal offense and that he was only incarcerated under tribal charges, Agent Egelhof again stated that he wanted to talk with Head about what had happened that morning. Head responded that he did not know why he was in custody, that he had “only been involved in capturing and holding a drug dealer, A ex Garcia, for the police” and that Garcia had tried to kidnap his daughter. April 2, *928 2002, Tr. at 4. The district court denied Head’s pre-trial motion to suppress this statement.
Head pled guilty to one count of aggravated assault but subsequently withdrew his plea following our decision in
United States v. Robert George Head, Jr.,
At trial, the prosecution called Alana Brown, who testified about what she remembered from the events that led to the charges against Head. The defense called Head’s wife, Mary, who testified outside of the presence of the jury that Brown had told her that Brown did not remember what had happened. The prosecution objected that Mary Head’s testimony was hearsay. The district court excluded the testimony after concluding that it had no probative value.
Following Head’s conviction, the district court sentenced him to concurrent 120-month terms for each of the aggravated assaults and a mandatory consecutive term of 84 months for brandishing a firearm during a crime of violence. The sentence reflected a two-level increase for leadership in the commission of a crime and a two-level increase for obstruction of justice.
Head challenges the district court’s denial of his motions to exclude the statements he made to Agent Egelhof and the evidence relating to the previously entered guilty plea. He also asserts that the district court improperly disallowed Mary Head’s rebuttal testimony. Finally, he challenges the district court’s sentencing enhancements based on facts not found by a jury beyond a reasonable doubt. 3
II.
We first address the district court’s denial of Head’s motion to suppress the statement made to Agent Egelhof. We examine factual findings for clear error and conclusions of law
de novo. United States v. Mendoza-Gonzalez,
The requirements of
Miranda
are triggered only when a defendant is both in custody and being interrogated.
United States v. Boyd,
The circumstances here are not unlike those in
Mendoza-Gonzalez,
III.
We next consider the district court’s deferral of Head’s motion to exclude evidence pertaining to his prior guilty plea. In
Luce v. United States,
the Supreme Court held that a defendant must testify in order to raise and preserve for review a claim of improper impeachment with a prior conviction.
IV.
Head contests the district court’s exclusion of Mary Head’s testimony. We review the district court’s determination of the admissibility of evidence for abuse of discretion.
United States v. Roulette,
Alana Brown testified on direct examination that she drank beer and smoked crack on the day in question. On cross-examination, Brown admitted that she had consumed between six and eight cans of beer. When asked on cross-examination whether she was “pretty intoxicated,” Brown responded: “Not really, I wouldn’t consider myself intoxicated. I drank, like, maybe six, seven beers, but I still knew what was going on.” March 17, 2004, Tr. at 81. She also stated that “even if I was [intoxicated], I still remember what all happened.” Id. at 83. At other points in her testimony, however, Brown stated that she could not remember certain details about the evening.
Mary Head testified outside the presence of the jury that Brown had told her that she had consumed twelve rather than eight cans of beer and that “she couldn’t really remember ... a lot of the things that the investigators were telling her about the other people’s statements [regarding the events of the night in question].” March 18, 2004, Tr. at 140-41. *930 The only disparities in Brown’s testimony that Mary Head’s testimony suggested were the number of beers that Brown had consumed and the extent to which Brown was able to remember the events that transpired that night.
The district court concluded that Mary Head’s testimony had no probative value and that Brown “was clear and candid on the witness stand that she doesn’t have a very good memory of it, parts of it.” Id. at 141. To the extent that Mary Head’s testimony would have had any probative value, we conclude that it would have been largely cumulative of Brown’s own testimony and thus would not have substantially impacted the jury’s verdict. Accordingly, any error in excluding it was harmless.
V.
Head’s reply brief challenges two sentencing enhancements based on facts not found by a jury beyond a reasonable doubt: a two-level increase for leadership in the commission of a crime, and a two-level increase for obstruction of justice. We address these challenges in light of
United States v. Booker,
— U.S. -,
In order to resolve Head’s challenges to his sentence, we conduct plain error review under the four-part test of
United States v. Olano,
The district court’s enhancements for leadership and for obstruction of justice were erroneous in light of
Booker.
In these circumstances, the first two
Olano
factors are satisfied.
See Pirani,
Absent the enhancements, Head would have faced a base offense level of 23 and a sentencing range of 84-105 months for his convictions on the two counts of aggravated assault. 4 The four-level adjustment to a base offense level of 27 resulted in a range of 120-150 months. The district court sentenced Head to 120 months. Although the district court sentenced Head to the low end of the sentencing range, nothing in the record suggests a reasonable probability that Head would have received a more favorable sentence had the district court been operating within a range of 84-105 months. Of. Id. at 553 (“[Sentencing at the bottom of the range is the norm for many judges, so it is insufficient, without more, to demonstrate a reasonable probability that the court would have imposed a lesser sentence absent the Booker error.”). In fact, the district court contemplated sentencing Head to consecutive 120-month terms for the *931 aggravated assault convictions, but ultimately concluded that concurrent sentences were appropriate given Head’s age. 5 We conclude that, given these circumstances, Head has not demonstrated prejudicial plain error under Olano.
The judgment and sentence are affirmed.
Notes
. The Honorable Ann D. Montgomery, United States District Judge for the District of Minnesota.
. We deny Head's November 1, 2004, pro se supplemental motion, which raises myriad other challenges.
. As indicated above, Head’s sentence also included a mandatory consecutive term of 84 months stemming from his conviction for brandishing a firearm during a crime of violence. The sentencing enhancements have no effect on this portion of Head's sentence.
. The district court commented to Head at sentencing that "[a]lthough there's much of your conduct both before the charges in this case and since which is aggravating and could be the basis for a consecutive time imposed more than this or at a different point in the guidelines, I find that under the circumstances, given your age, 204 months [120 months for the aggravated assault convictions and 84 months for the conviction for brandishing a firearm] is a very long sentence and is sufficient to comply with society's need for punishment as it relates to this offense and particularly the conduct you’ve engaged in since the time of your arrest.” Sen. Tr. at 22.
