Keane Vallie was convicted by a jury of sexual abuse under 18 U.S.C. § 1153 and § 2242(2)(A) and incest under 18 U.S.C. § 1153 and North Dakota Century Code §§ 12.1-20-11, -32.01. He appeals his convictions, and we affirm.
On the evening of February 4, 2000, Vallie was at the home of his sister, Elma Martell, on the Turtle Mountain reservation. A number of people had congregated there to visit, listen to music, and drink alcohol. Martell went to bed at approximately 4:00 a.m. Shortly after she fell asleep, she was awakened by a man having sexual intercourse with her. The man was behind her and said nothing. Martell did not suspect that he was not her husband, and the man repeated the act approximately thirty minutes later. The man pulled up Martell’s underwear and covered her when he was finished, which aroused her suspicions because this type of behav *920 ior was not like her husband. Martell spoke to the man as he was leaving the room, he turned, and she saw then that he was Vallie.
Martell cleared everyone out of her residence, and one of her sisters came over and gathered Martell’s bedding and underwear into a bag and called the police. Officers sent the bag to the FBI laboratory for DNA analysis, along with rape kits obtained from Martell and Vallie. Analysis revealed that all DNA present on the vaginal swabs and underwear came from Martell and Vallie. Vallie was indicted for sexual abuse, under 18 U.S.C. § 2242(2)(A) and § 1153, and incest, under 18 U.S.C. § 1153 and North Dakota Century Code §§ 12.1-20-11, -32-01. The case was tried before a jury which convicted on both counts. The district court 1 denied Vallie’s motion for a new trial and sentenced him to 70 months.
Vallie appeals his convictions, arguing that the district court erred by admitting the DNA evidence, undisclosed blood alcohol tests, and testimony from an investigator who gave inaccurate grand jury testimony. Vallie also contends that the court did not adequately sequester witnesses and that the prosecutor committed misconduct by asking him about a prior offense unrelated to sexual conduct and by vouching for the credibility of witnesses. Finally, he contends that 18 U.S.C. § 1153(b) violates his right to equal protection because it uses state criminal law to define federal offenses and thus imposes nonuniform standards of liability and punishment.
Vallie asserts that the district court erred by admitting the DNA evidence because it was obtained from items that were collected by Martell’s sister and that lacked a proper chain of custody. Martell’s bedding and underwear were potential sources of highly relevant evidence since she claimed she had been sexually assaulted. Physical evidence may be admitted if “a reasonable probability exists that the evidence has not been changed or altered,”
United States v. Cannon,
Vallie also renews his objection that the court erred by admitting the results of Martell’s blood alcohol tests because they had not been previously disclosed to defense counsel. The government is under an obligation to disclose exculpatory evidence,
Brady v. Maryland,
Vallie argues that the district court erred by allowing an investigator to testify at trial after he erred in his testimony before the grand jury. Vallie points to the following inaccuracies in the investigator’s testimony to the grand jury: the investigator said that DNA evidence was “found in the saliva — or vagina swabs and on the mattress” (the DNA came from the vaginal swabs and the underwear Martell wore to bed), that actual semen was found when it was not, and that Martell was awake when the man first came into her bedroom. Vallie brought out the inconsistencies in the testimony of the investigator on his cross examination at trial, but Vallie did not object during direct examination of the witness. Our review is therefore for plain error.
United States v. McBride,
Vallie argues that the district court erred by allowing courtroom spectators to communicate with sequestered witnesses and by calling sequestration “asinine.” Sequestration of most witnesses is mandatory when requested, Fed.R.Evid. 615, but the district court is granted wide latitude in implementing sequestration orders and the standard of review is abuse of discretion.
United States v. Kindle,
Vallie argues that his convictions should be reversed because it was misconduct for the prosecutor to ask him about a prior offense unrelated to sexual conduct. A prosecutor commits misconduct by asking an improper question so offensive as to prejudice the defendant’s substantial rights and deprive him of a fair trial.
United States v. Guerra,
Vallie also argues that the prosecutor impermissibly vouched for the credibility of the witnesses when she stated during closing argument that she knew every witness.
See Guerra,
Finally, Vallie argues that 18 U.S.C. § 1153(b) violates his right to equal protection because it uses state criminal law to define federal offenses and thus imposes differing standards of liability and punishment depending upon where an offense is committed. Section 1153(a) creates exclusive federal jurisdiction over certain crimes, including sexual assault or incest, committed by “[a]ny Indian.. .within the Indian country.” Federal law does not define incest, but § 1153(b) provides that it “shall be defined and punished in accordance with the laws of the State in which such offense was committed.” Val-lie notes that each state defines and punishes incest differently and that an Indian committing incest on a reservation located in one state will receive different treatment than an Indian committing incest on a reservation located in another state, even though both reservations are within exclusive federal jurisdiction.
In
United States v. Yazzie,
For the foregoing reasons, we affirm the judgment of the district court.
