MEMORANDUM
Tony Mix appeals his conviction and sentence on two counts of kidnaping, five counts of aggravated sexual abuse, and two counts of assault with a dangerous weapon.
1. Mix challenges the admission of certain expert testimony by Dr. Ferraro, a sociologist who opined (without objection to her qualifications to testify) on the subject of domestic violence. In general, Dr. Ferraro’s testimony regarding the dynamics of abusive relationships was properly admitted because it assisted the jury in understanding the evidence and provided context for Tohannie’s testimony. See, e.g., United States v. Rahm,
2. Mix also challenges the admission of Dr. Aimer’s expert testimony on paranoia and borderline personality disorder. Mix did not object to this testimony, so we review for plain error. None of Dr. Aimer’s testimony went directly to Mix’s mental state, however, so his testimony did not violate Rule 704(b). See United States v. Brown,
3. We reject Mix’s contention that once error had been introduced by allowing Dr. Ferraro to testify to Mix’s mental state, defense expert Dr. Walter should have been allowed to testify as to whether he thought Mix “understood right from wrong and the wrongfulness of his acts.” A court need not allow a further violation of Rule 704(b) as a remedy for a prior violation and may instead “properly conclude that [such further violation] would be more prejudicial than helpful.” Kristiansen,
4. Nor did the district court err in allowing the testimony of other women previously subject to Mix’s physical abuse because this evidence was probative of Mix’s state of mind and was not improper propensity evidence. Further, the district court gave an appropriate limiting instruction, cautioning the jury that evidence of prior acts of abuse could be considered “only as it bears on the defendant’s motive, intent, preparation, plan, knowledge, identity, or absence of mistake and for no other purpose.”
5. The district court did not abuse its discretion in admitting Tohannie’s hospital records. The records were properly authenticated. See United States v. Ray,
6. Mix contends that he was denied his right to a public trial by the court’s exclusion of witnesses following their testimony. This contention fails as a factual matter because the court did not exclude witnesses after they completed their testimony. The court did order Sherry Mix, Mix’s sister, excluded from the courtroom during Tohannie’s testimony. Although Sherry Mix had at one time been identified as a witness, she was not called to testify. The district court had a substantial reason for excluding Sherry
7. The district court did not abuse its discretion by declining to instruct the jury on diminished capacity. Mix fails to point to any evidence elicited at trial that he was unable to form the specific intent necessary to commit the charged crimes, see United States v. Washington,
8. Although the prosecutor improperly vouched for the credibility of Dr. Aimer once during his rebuttal closing, Mix failed to object. We find no plain error in view of the overwhelming evidence of Mix’s guilt and the court’s curative instructions to the jury. See United States v. Parker,
9. Cumulatively, the violation of Rule 704(b) and the one instance of improper prosecutorial vouching create no more prejudice than they do independently and, in view of the strength of the prosecution’s case, are not sufficiently prejudicial to undermine the reliability of the verdict. Cf Killian v. Poole,
10. The district court did not err in adjusting Mix’s base offense level pursuant to U.S.S.G. § 2A3.1(b)(5) (abduction) because Mix forced his victim at knifepoint into a back room to continue the assault. See United States v. Jordan,
11. The court did err, however, in departing upward for uncharged conduct pursuant to U.S.S.G. § 5K2.21, which did not become effective until November 1, 2000, one day after Mix’s last charged acts. See United States v. Chea,
AFFIRMED in part, REVERSED in part, and REMANDED for resentencing.
Notes
This disposition is not appropriate for publication and may not be cited to or by the courts of this circuit except as provided by Ninth Circuit Rule 36-3.
. Even if the admission of this specific testimony were not harmless error, because Dr. Ferraro’s statement was directed to Mix’s state of mind solely on October 30, 2000, it would affect only Mix's conviction on counts one through eight; Mix's life sentence on count nine for kidnaping Tohannie on or about July 2, 2000 would still stand.
