In these consolidated criminal appeals, Pippert and Floyd (collectively, “Defendants”) appeal their convictions and sentences for mailing threatening communications, 18 U.S.C. § 876. We affirm both the convictions and sentences.
I. BACKGROUND
Floyd and Pippert, who is Floyd’s daughter, admit that they sent a copy of an article about United States District Court Judge Joan Lefkow’s murdered family to a lawyer, two judges, and the district court connected to various litigation previously involving the Floyd family in the Iowa state court system. The handwritten words “Be Aware Be Fair” appeared on the article. Defendants did not sign their names or include a return address on the envelopes. They were caught due to good detective work by the recipients of the letters, and the fact that the Floyds were known as prolific letter writers in connection with their litigation. When confronted by authorities, both Pip-pert and Floyd admitted to sending the letters, but denied that they intended to threaten or intimidate the recipients. However, at trial, Defendants were not allowed to present evidence of their actual intent in sending the letters. The district court ruled, in limine, that because intent to threaten was not an element of the offense, such evidence was not relevant and therefore inadmissible. The district court 1 also refused to instruct the jury *847 that intent to threaten was an element of the offense.
Upon conviction, the district court sentenced Floyd to 33-months’ imprisonment, and Pippert to 36-months’ imprisonment. Both sentences are within the guidelines range, but Pippert was given a two-level increase for obstruction of justice. In this regard, the district court found that Pip-pert gave perjured testimony at trial.
Defendants challenge the district court’s decision that the government was not required to prove that they intended to threaten the recipients with the mailing. They also allege there was insufficient evidence that the communication was a threat, and that the district court should have granted their motion for judgment of acquittal on this issue rather than submitting it to the jury. Finally, Defendants assert that their sentences should be vacated.
II. DISCUSSION
We review the district court’s jury instructions and evidentiary rulings for an abuse of discretion.
United States v. Florez,
A. Intent
Defendants contend that the district court erred in refusing to instruct the jury that intent to threaten the recipients was an element of an 18 U.S.C. § 876 offense. Section 876(c) makes it unlawful for anyone to “knowingly” use the United States mail service to send a communication “containing ... any threat to injure the person of the addressee or of another.” Our circuit • precedent requires that the government prove two things in a section 876 case: “(1) that the defendant wrote a threatening letter and (2) that the defendant knowingly caused the letter to be forwarded by the United States mail.”
United States v. Lincoln,
Notwithstanding this precedent, Defendants argue, based on
Virginia v. Black,
The statute at issue in
Black
explicitly required proof of intent to intimidate. The Court found that the statute was constitutional, so long as the government was not allowed to use the cross-burning act itself as prima facie evidence that the actor intended to intimidate or threaten. Instead, the government was required to prove that the actor actually so intended.
Id.
at 359-63,
There has been no First Amendment challenge in this case,
2
and on that basis alone,
Black
is distinguishable. And, our panel is bound by
Koski,
decided two years after
Black,
which specifically noted that the intent of the sender is not an element of a section 876(c) offense.
So, based on existing Eighth Circuit precedent, the district court did not err in refusing to instruct the jury that the government must prove Defendants intended to threaten the recipients, and the government met its burden of proving that Defendants intended to send the letters. In fact they admit doing so. The core issue for Defendants is whether the letters were, in fact, threatening. 4
B. True Threat
Defendants argue there was insufficient evidence that the letters were truly threatening, and as such, the district court should have granted the motion for judgment of acquittal and not sent the issue to the jury. In evaluating threats under 18 U.S.C. § 876, a district court should submit the issue for jury determi
*849
nation “ ‘[i]f a reasonable recipient, familiar with the context of the communication, would interpret it as a threat.’ ”
Whitfield,
In order to decide that issue, in
Bellrichard,
we noted that the communication must be viewed in “textual context and also in the context of the totality of the circumstances in which the communication was made.” ,
Defendants argue that the communication is ambiguous, and therefore they should have prevailed on their motion for judgment of acquittal, citing
United States v. Barcley,
The
Bellrichard
defendant made a similar “ambiguity” argument based on
Barcley.
In rejecting this claim, we noted that the issue before us on appeal was “whether the government made a submissible case” that the vitriolic letters sent by Bellrichard could be objectively viewed as threatening.
Bellrichard,
We reject Defendants’ ambiguity arguments on a similar basis (though we do not suggest that the communications .at issue here compare favorably with the letters in Bellrichard). The Barcley letter was written, signed, and sent by a prisoner unhappy with his appointed appellate *850 counsel. The anonymous, photocopied newspaper articles, about a judge’s murdered family, with the aforementioned phrase written on top and sent to judicial officers, are quite different in both content and context. The district court did not err in finding that the government made a submissible case on whether the communications contained a threat. Accordingly, we affirm Defendants’ convictions.
C. Sentencing
Pippert and Floyd both concede that the district court correctly calculated their guidelines sentence ranges, and sentenced them within those ranges. Pippert challenges her two-level enhancement for obstruction of justice and also challenges the district court’s refusal to give her a reduction for acceptance of responsibility or aberrant behavior. Both Pippert and Floyd challenge their sentences as unreasonable.
Obstruction
In determining whether an obstruction enhancement should be applied, the district court must review the evidence and find, by a preponderance of the evidence, that the defendant gave “false testimony concerning a material matter with the willful intent to provide false testimony, rather than as a result of confusion, mistake, or faulty memory.”
United States v. Ziesman,
The district court added the obstruction enhancement because Pippert told police, and testified, that she only sent the article to the attorney and judges because she wanted them to know what had happened to Judge Lefkow’s family, and she was not sure they would have read the paper. She also said that her failure to put a return address on the envelope was not to conceal her identity. At sentencing, the district court found that both of those statements were perjured statements, about a material issue, and not as a result of confusion, mistake, or faulty memory.
The district court’s credibility determination on this matter can be reversed only upon a showing of clear error.
United States v. Galaviz-Luna,
Acceptance of responsibility
Because we find that the obstruction enhancement was proper, we likewise cannot reverse the district court’s refusal to grant the acceptance adjustment, absent extraordinary circumstances.
United States v. Campos,
*851 Aberrant behavior
Pippert alleges that she was entitled to a departure for aberrant behavior because she is a law-abiding and God-fearing citizen. However, these are characteristics the guidelines already take into account (lack of criminal history),
United States v. Wind,
Reasonableness
Finally, Floyd and Pippert argue that their sentences are unreasonable. A sentence is unreasonable when the district court has relied significantly on impermissible factors, failed to account for permissible factors, or otherwise committed a clear error of judgment.
United States v. Haack,
III. CONCLUSION
We affirm the district court.
Notes
. The Honorable Linda R. Reade, United States District Judge for the Northern District of Iowa.
. We rejected a First Amendment challenge to a section 876 conviction in
United States v. Bellrichard,
. The statute is somewhat ambiguous with regard to what the word "knowingly” modifies. Section 876 provides criminal penalties for "whoever knowingly so deposits or causes to be delivered ... any communication ... containing ... any threat to injure the person of the addressee or of another.” 18 U.S.C. § 876(c). Arguably, the "knowingly” language could modify all the elements of the statute-requiring that the sender not only "knowingly” used the mails to send the letter, but also that the sender "knew” that the letter contained threatening language.
See, e.g., Liparota v. United States,
.Defendants also challenge the district court's ruling in limine that they could not present evidence regarding what their subjective intent was in mailing the articles. However, because such evidence is not relevant for conviction of the offense,
