I. INTRODUCTION
On September 13, 2002, defendant-appellant Shawn P. Williams' was convicted after a jury trial on seven counts of mailing threatening communications in violation of 18 U.S.C. § 876. Williams was tried in the United States District Court for the District of Colorado. Three letters evidencing other wrongful acts were admitted at trial over Williams’ objection pursuant to Fed.R.Evid. 404(b) and Fed. R.Evid. 403. The jury returned a guilty verdict on all counts. Williams moved for a judgment of, acquittal pursuant to Fed. R.Crim.P. 29. The district court denied *1050 the motion and sentenced Williams to 78 months’ imprisonment.
Williams appeals the district court’s denial of his Rule 29 motion and the district court’s admission of the three letters pursuant to Fed.R.Evid. 404(b). Exercising jurisdiction pursuant to 28 U.S.C. § 1291, this court affirms Williams’ convictions.
II. BACKGROUND
While serving a ten-year sentence for attempted rape at the Maine Department of Corrections, Williams began to mail numerous threatening letters, at first warning United States officials about visions he had of unsolved and potential murder cases. Williams continued his mailings when transferred to federal prison, and his subsequent letters included bomb and sexual mutilation threats. United States Marshal James Werner was sent to interview Williams, who admitted to writing and sending the threatening letters after waiving his Miranda rights. In August 2000, Williams was indicted on seven counts of mailing threatening communications in violation of 18 U.S.C. § 876.
Prior to trial, Williams moved in limine to exclude letters which he argued were inadmissible under Fed.R.Evid. 404(b) and Fed.R.Evid. 403 because they contained uncharged threats to various individuals and entities. The motion was denied in part and three of the challenged documents 1 were admitted at trial over Williams’ objection. The judge gave limiting instructions regarding the purposes for which the jury could consider the three letters.
At trial, Williams testified that he caused each of the letters underlying the seven counts of the indictment to be mailed and that he had labeled them as “legal mail.” Williams further testified that he intended that the recipients take his threats seriously so that he could “get their attention.” Werner testified that Williams told him that he intentionally “disguise[d]” the threatening letters as legal mail to avoid inspection by prison mail monitors.
Following closing arguments, the jury tendered a question inquiring whether the phrase “ ‘addressed to a person’ mean[t] the address on the envelope or the greeting in a letter” and whether the communications alleged in the indictment had to be addressed to an “individual name” as opposed to “an office.” In response, the court issued a supplemental jury instruction (“supplemental instruction”), which stated that the addressee on the face of the envelope controls, that an agency of the federal government is not a “person” within the meaning of 18 U.S.C. § 876, and that an official of the federal government may be a “person” within the meaning of *1051 the statute, even if not identified by proper name. The government objected to this instruction. Williams moved for a judgment of acquittal, arguing that in light of the supplemental instruction, the jury could not find him guilty of the crimes charged. The court took the motion under advisement and denied it after the jury returned guilty verdicts on all counts. 2
III. DISCUSSION
A. Denial of Motion for Judgment of Acquittal
This court reviews the sufficiency of the evidence to support a conviction or the denial of a defendant’s motion for judgment of acquittal
de novo. United States v. Colonna,
Williams argues that the district court erred in denying his motion for judgment of acquittal because the government failed to prove that he mailed a threat “addressed to any other person” as that element of the charged crime was defined by the supplemental instruction. Williams contends that no rational jury could have found him guilty because the supplemental instruction directed the jury to consider the addressee on the envelope and stated that a government agency is not a person within the meaning of 18. U.S.C. § 876. Williams argues that because of. the supplemental instruction, the jury’s verdict cannot be justified on the basis of the letters’ salutations or contents.
This court need not decide whether there was sufficient evidence to support Williams’ convictions as constrained by the supplemental instruction because the doctrine of law of the case does not apply under the circumstances of this case. The law of the case is applied to hold the government to the burden of proving each element of a crime as set out in a jury instruction to which it failed to object, even if 'the unchallenged jury instruction goes beyond the criminal statute’s requirements.
See United States v. Romero,
In order to resolve the question whether Williams’ conviction on each of the seven counts was supported by sufficient evidence, this court must first decide whether one can look at both the envelope and the salutation to determine whether the letter is “addressed to any other person” within the meaning of 18 U.S.C. § 876 (2000). This court must also decide whether a government official can be a “person” within the meaning of § 876. 4 Both are questions of first impression.
This court holds that one can look, at a minimum, to both the envelope and the salutation of a letter in determining whether the letter is “addressed to any other person” within the meaning of § 876. Plain meaning controls statutory interpretation.
Ctr. for Legal Advocacy v. Hammons,
Furthermore, this court holds that a government official is a person within the meaning of § 876.
6
Section 876 is ambiguous with respect to who qualifies as a “person” because it does not define the word “person.” 18 U.S.C. § 876. As a consequence, this court turns to congressional intent and to the purpose of the statute in interpreting the word “person.”
In re Geneva Steel Co.,
An interpretation of the word “person” which includes government officials is consistent- with another purpose of § 876. ■ ■ As the Seventh Circuit has noted, at' least ón'e of the purposes of § 876 is “the preservation of the recipient’s sense of personal safety.”
United States v. Aman,
Our holdings are consistent with the only three cases which have directly interpreted § 876’s requirement that the threatening communication be “addressed to any other person.” Consistent with our holding that both the envelope and the salutation aré relevant in determining to whom a - communication is addressed, a district court ruled that “a threatening letter is ‘addressed’ to a person within the meaning of § 876 if the letter itself is directed to the attention of a specific person, even though- the delivery instructions
*1054
direct that the mail carrier deliver the letter to an institution.”
United States v. Chapman,
In light of the above principles, there was sufficient evidence to support Williams’ conviction on each of the seven counts. Williams admitted on the witness stand to mailing each of the letters that underlie the seven counts of the indictment. Each of these seven letters contained threats to injure government officials. Furthermore, a reasonable jury could have found that each of the admitted communications was “addressed to any other person” within the meaning of § 876 because each communication was addressed to a government official. With respect to the communication underlying count one, the jury could have reasonably inferred that the salutation “Hey Asshole” was addressed to the U.S. Attorney, given that the envelope was addressed to “U.S. Dist. Attorney Office’s.” The salutation of the letter relating to count two expressly addresses the “U.S. Attorney.” The envelopes of the communications underlying counts three and five were addressed to the “Clerk of Courts.” The salutation of the letter concerning count four expressly addressed the “U.S. Attorney.” The jury could have reasonably inferred that the salutation of the letter underlying count six, “Hey Asshole, D.A.,” addressed the United States Attorney in Colorado, who is a government official. Lastly, the salutation of the letter underlying count seven expressly addressed the “U.S. Attorney.”
In light of these threatening communications addressed to government officials and of Williams’ admission to mailing them, there was sufficient evidence to support Williams’ conviction on each of the seven counts. Thus, the district court did not err in denying Williams’ motion for judgment of acquittal.
B. Admission of Evidence of Uncharged Threats
This court reviews a district court’s decision to admit evidence for an abuse of discretion.
United States v. Kravchuk,
Williams argues that the district court erred in admitting Government Exhibits 11, 14, and 17, and that the error was not harmless. This court need not rule on the admissibility of these letters because it holds that, even if the letters were erroneously admitted at trial, the error was harmless. A conviction will be affirmed if the error was harmless in light of the record as a whole.
United States v. Bornfield,
Any error in admitting the challenged evidence was harmless because the evidence of Williams’ guilt was overwhelming.
United States v. Oberle,
IV. CONCLUSION
For the foregoing reasons, this court AFFIRMS Williams’ conviction on each of the seven counts.
Notes
. The three controverted documents which were admitted are:
(1) Government Exhibit 11: envelope addressed to “Clerk of Courts.” The letter threatened to "have you beaten, raped, sodomized & killed-BITCH!” and to "have that faggot-ass U.S. Attorney, the courthouse & half of Denver, CO., blown up & destroyed, BITCH! ”
(2) Government Exhibit 14: envelope addressed to "Governor Bill Owens.” The letter contained some white, crushed Tylenol powder which Williams claimed was anthrax and stated "Welcome to your Anthrax-Death!” The letter was signed "Osama-Bin-Laden, A.K.A. Shawn P. Williams.”
(3)Government Exhibit 17: envelope addressed to "Clerk of Courts.” The letter threatened to rape, kidnap, and kill a particular secretary who worked for the courts.
The district court reasoned that these exhibits were probative of Williams' intent to instill fear, identity, modus operandi, opportunity, motive, and "misuse and knowledge of the [prison] legal mail process.” The district court concluded that the probative value of these exhibits outweighed their prejudicial effects.
. The letters and envelopes underlying each count were introduced into evidence. Each letter contained threats. The addressees on the envelopes and salutations are as follows:
(1) Count one: envelope addressed to "U.S. Dist. Attorney Office's, c/o U.S. District Courts.” Salutation: "Hey Asshole.”
(2) Count two: envelope addressed to "U.S. Atty’s Office’s. c/o-U.S. District Courts.” Salutation: "Hey, U.S. Attorney.”
(3) Count three: envelope addressed to "Clerk of Courts. U.S. District Courts.” Salutation: "Hey, Bitch.”
(4) Count four: envelope addressed to “U.S. Attorney's Offices. c/o-U.S. District Courts.” Salutation: "Dear U.S. Attorney.”
(5) Count five: envelope addressed to "Clerk of Courts. U.S. District Courts.” Salutation: "Dear Clerk.”
(6) Count six: envelope addressed to "U.S. Attorney’s Office's. c/o-U.S. District Courts.” Salutation: "Hey Asshole, D.A.”
(7) Count seven: envelope addressed to "U.S. Attorney’s Offices. c/o-U.S. District Courts.” Salutation: "Dear, U.S. Attorney.”
. Williams relies on a Ninth Circuit case for the proposition that this court must evaluate his sufficiency claim in light of the elements as set out in the supplemental instruction.
See United States v. Arteaga,
. In November 2002, Congress amended § 876 to, in part, impose a greater term of imprisonment for letters addressed to "a United States judge, a Federal law enforcement officer, or an official....” 18 U.S.C. § 876(c) and (d) (2002). United States Attorneys and their assistants are included in the definition of federal officials. Id.; 18 U.S.C. § 1114. This amendment makes it clear that government officials are persons within the meaning of the current version of § 876. This opinion, however, analyzes whether officials are persons within the meaning of § 876 as it was written in 2000, when Williams was charged.
. At the time Williams was charged in 2000, § 876 read, in relevant part: "[wjhoever ... knowingly causes to be delivered by the Postal Service ... any communication, with or without a name or designating mark subscribed thereto, addressed to any other person and containing any threat to ... injure the person of the addressee or of another, shall be fined under this title or imprisoned not more than five years, or both.” 18 U.S.C. § 876 (2000) (emphasis added).
. Other circuits have affirmed convictions for mailing threatening communications that were either addressed to, or threatened, government officials.
