TERRANCE N. THOMAS,

Defendant - Appellant.

APPEAL FROM THE UNITED STATES DISTRICT COURT

FOR THE DISTRICT OF WYOMING

(D.C. No. 04-CR-07-J)

Thomas A. Fleener, Assistant Federal Public Defender (Raymond P. Moore, Federal Public Defender, with him on the brief), Cheyenne, Wyoming, for Defendant-Appellant.

James C. Anderson, Assistant United States Attorney (Matthew H. Mead, United States Attorney, with him on the brief), Cheyenne, Wyoming, for Plaintiff-
Appellee.

Before O'BRIEN, ANDERSON, and McCONNELL, Circuit Judges.

ANDERSON, Circuit Judge.

Terrance N. Thomas ("Thomas") was convicted following a jury trial of two counts of using interstate commerce to attempt to persuade a minor to engage in an illegal sexual act, in violation of 18 U.S.C. § 2422(b). Thomas was sentenced to two concurrent sentences of seventy months' imprisonment, five years' supervised release, and $450 in fines and assessments. He appeals his conviction and sentence. We AFFIRM.

BACKGROUND

On June 12, 2003, Special Agent Flint Waters ("Waters") of the Wyoming Division of Criminal Investigation visited a YAHOO! chat room using the screen name "angelgirl12yo." Waters had created a profile on YAHOO! for "angelgirl12yo" indicating she lived in Cheyenne. While Waters was in the chat room, Thomas, using the screen name "blackass_blk," typed "all Cheyenne ladies represent." Waters testified that he understood this as an invitation for all females from Cheyenne to get in touch with Thomas. Thomas had also created a profile in YAHOO! in which he posted his picture and described himself as 28 years old, single, and an independent contractor. He listed his hobbies as "chillin, clubin, lifting weights, fuckin, working on my website." Appellee's App. at 3.

Waters, still using the screen name angelgirl12yo, and mimicking the manner in which a preteen girl would conduct an Internet chat, responded to blackass_blk's request to "represent." The following chat ensued:

angelgirl12yo (2:09:37 PM): Cheyenne

angelgirl12yo (3:18:48 PM): well?

Id. at 2. Officers then set up surveillance at the Burger King and awaited Thomas's arrival. A white vehicle with a Warren Air Force Base decal driven by a black man entered the parking lot. Police detained the driver but soon learned that he was not Thomas. Thomas never showed up at the Burger King, and Waters speculated that he may have seen the police activity in the parking lot and been deterred. Waters closed the investigation.

However, six months later, on December 22, 2003, Waters was again online in a YAHOO! chat room. This time he was using the persona "cheygirl13," for whom he had also created a YAHOO! profile. Waters observed that the persona "blackassblk" was online and available for messaging. Because of the similarity between this screen name and the screen name he encountered in June ("blackass_blk"), Waters accessed the profile and photo for this persona and learned that "blackassblk" was Thomas. Cheygirl13 then contacted blackassblk and the following chat took place:

cheygirl13 (5:30:19 PM): hi

blackassblk (5:51:14 PM): OK

Id. at 4. Immediately after the chat ended, Waters and other agents established surveillance at the intersection where Thomas was supposed to meet cheygirl13. They observed a white passenger car pull to a curb and turn off its lights. Without turning its lights back on, the car pulled back out, made a U-turn, and then pulled into a parking lot. Finally, the car pulled back out into the street, at which point the agents stopped the vehicle. Thomas was driving the car and his two small children were in the back seat.

The defendant was advised of his Miranda rights. He admitted that he was online and had been using the screen name blackassblk to chat with a girl, but he denied knowing that she was 13 and said that he had not caught her age because one of his children had been playing with the computer. He also said he had changed his mind about engaging in sexual activities with her and had "slipped."

Officers then obtained consent to search Thomas's home, where they discovered a locked room containing the computer he had been using. The computer was on. A pornographic movie was playing on the computer and in the foreground was the chat with cheygirl13. Waters seized the computer and searched its hard drive and found the entire chat with cheygirl13 preserved on the computer. The examination also revealed that Thomas had accessed cheygirl13's YAHOO! profile.

Initially, Thomas was charged with one count of violating 18 U.S.C. § 2422(b) for the December 22, 2003, incident. The district court admitted the June 2003 chat between Thomas and angelgirl12yo as Fed. R. Evid. 404(b)1 evidence. Thomas went to trial on the charge, but it resulted in a hung jury and a mistrial was declared. Thomas was later charged by superseding indictment with two counts of violating 18 U.S.C. § 2422(b), one count for the June chat and one count for the December chat. The jury found him guilty of both counts.

Thomas appeals his conviction, arguing: (1) that 18 U.S.C. § 2422(b) is unconstitutionally vague and overbroad; (2) that the district court erred in admitting evidence that Thomas traveled to the supposed meeting place with cheygirl13; (3) that there was insufficient evidence to support his conviction on either count; and (4) the government engaged in vindictive prosecution by charging him with two counts in the superseding indictment. Thomas also challenges his sentence, arguing that it violates United States v. Booker, 125 S. Ct. 738 (2005), because the district court sentenced him while operating under the then-mandatory federal Guidelines system.

DISCUSSION

A.

I.	Constitutionality of 18 U.S.C. § 2422(b)

Title 18 U.S.C. § 2422(b) provides:

Whoever, using the mail or any facility or means of interstate or foreign commerce . . . knowingly persuades, induces, entices, or coerces any individual who has not attained the age of 18 years, to engage in prostitution or any sexual activity for which any person can be charged with a criminal offense, or attempts to do so, shall be fined under this title and imprisoned not less than 5 years and not more than 30 years.

18 U.S.C. § 2422(b). Thomas first argues that because the district court and other courts have interpreted the statute as requiring only the intent to entice a minor for illegal sexual activity and not intent to commit the underlying sexual offense, the statute is overbroad in violation of the First Amendment. Thomas thus asserts that the statute "impinges on constitutionally protected speech including the fundamental right to parent."2 Appellant's Opening Br. at 10. Second, he asserts that the statute is void for vagueness because the terms are unclear, causing "men of common intelligence [to] necessarily guess at its meaning." Id.

We review challenges to a statute's constitutionality de novo. Ward v. Utah, 398 F.3d 1239, 1245 (10th Cir. 2005). The overbreadth doctrine "prohibits a statute from making criminal otherwise innocent and constitutionally protected conduct." United States v. Pinelli, 890 F.2d 1461, 1472 (10th Cir. 1989). "The crucial question then is whether the statute sweeps within its prohibitions conduct that may not be punished because of the protection of the first and fourteenth amendments." Id. Similarly, the "void for vagueness doctrine requires that a penal statute define a criminal offense with sufficient specificity that ordinary people can understand what conduct is prohibited and in a manner that does not encourage arbitrary and discriminatory enforcement." Id. at 1470. The Supreme Court "has recognized that the most important aspect of the vagueness doctrine 'is not the actual notice [to citizens of prohibited conduct], but the other principal elements of the doctrine—the requirement that a legislature establish minimal guidelines to govern law enforcement.'" Id. (quoting Smith v. Goguen, 415 U.S. 566, 574 (1974)).

Although we have not spoken on this question, Thomas points to no case in which a court presented with an overbreadth or vagueness challenge to § 2422(b) has deemed the statute unconstitutional.3 See, e.g., United States v. Dhingra, 371 F.3d 557, 561-63 (9th Cir. 2004) (overbreadth challenge fails because statute regulates conduct—inducement of minors for sexual activity—not speech; vagueness argument also fails); United States v. Meek, 366 F.3d 705, 720-22 (9th Cir. 2004) (same); Panfil, 338 F.3d at 1300-01 (statute not vague or overbroad because its terms have plain and ordinary meanings and statute includes scienter requirement); United States v. Bailey, 228 F.3d 637, 639 (6th Cir. 2000) (no overbreadth or ambiguity problems because statute only applies to those who target minors, and "the Defendant simply does not have a First Amendment right to attempt to persuade minors to engage in illegal sexual acts").

We agree with the reasoning of the circuits that have already considered and upheld the constitutionality of the statute in question. Section 2422(b) requires only that the defendant intend to entice a minor, not that the defendant intend to commit the underlying sexual act. Contrary to Thomas's assertions, this interpretation does not render the statute unconstitutionally overbroad or void for vagueness.

II.	Evidence that Thomas traveled to meet cheygirl13

Thomas next argues that the court abused its discretion by admitting Waters' testimony that Thomas was stopped near the intersection where he planned to meet cheygirl13. He asserts that because the district court ruled that the government needed only to prove intent to entice, not intent to engage in the underlying sexual act, this evidence was admitted in violation of Fed. R. Evid. 401, because it was irrelevant, and Fed. R. Evid. 403, because it was more prejudicial than probative. The defendant filed a motion in limine to exclude the testimony below, but the court denied the motion, stating, "I view it as additional evidence of a substantial step in terms of the offense charged, but, at any rate, certainly evidence that is intertwined with the offense." Tr. of Jury Trial, R. Vol. 5 at 107.

We review a trial court's decision to admit or exclude evidence for an abuse of discretion. United States v. Hernandez-Herrera, 952 F.2d 342, 343 (10th Cir. 1991). We will not overturn an evidentiary ruling "absent a distinct showing that it was based on a clearly erroneous finding of fact or an erroneous conclusion of law or manifests a clear error of judgment." United States v. Jenkins, 313 F.3d 549, 559 (10th Cir. 2002).

The district court did not abuse its discretion in admitting Waters' testimony about where he stopped Thomas. The evidence may not have been required to prove that Thomas was guilty of the second count of violating § 2422(b), considering that he was convicted on the first count without any proof that he traveled to meet angelgirl12yo. See infra Part III. The evidence nonetheless helped demonstrate his intent. Thomas would not have been at the supposed meeting place had he not intended to entice cheygirl13 to meet him there to engage in oral sex. See Dhingra, 371 F.3d at 565 (agent's testimony that defendant actually engaged in sexual activity with minor admissible to prove enticement charge even though "evidence of sexual contact is not required under § 2422(b)"). Moreover, defendant has not sufficiently identified how this testimony presented "unfair prejudice," except to say that it permitted the jury to focus on Thomas's intent to actually engage in sexual activities with the girl. Assuming the evidence can be viewed as prejudicial, it is outweighed by its probative value.

Finally, we reject Thomas's argument that the evidentiary ruling was erroneous because the judge failed to articulate his Rule 403 balancing analysis. Thomas acknowledges in his brief that we have consistently upheld implicit Fed. R. Evid. 403 determinations when they are supported by the record. United States v. Lazcano-Villalobos, 175 F.3d 838, 846-47 (10th Cir. 1999). Such is the case here. The district court did not err in admitting this evidence.

III.	Sufficiency of the evidence

Thomas next argues that there was insufficient evidence to convict him of either count, but particularly of count one, the June 2003 chat with angelgirl12yo. He contends that there was no proof that he knew how old angelgirl12yo was because the age section of her YAHOO! profile was left blank, and he argues that there was no evidence, as there was for the second count, that he actually attempted to meet angelgirl12yo.4

We review sufficiency of the evidence claims de novo. United States v. Munro, 394 F.3d 865, 869 (10th Cir.), cert. denied, 73 U.S.L.W. 3631 (U.S. Apr. 25, 2005) (No. 04-9423). "In doing so, we view all evidence in the light most favorable to the prevailing party below. . . . Ultimately, we must determine whether the evidence and all reasonable inferences drawn therefrom could allow a reasonable jury to find [Thomas] guilty beyond a reasonable doubt." Id.

We recently set forth the four elements that must be proven to show a violation of 18 U.S.C. § 2422(b): (1) use of a facility of interstate commerce; (2) to knowingly persuade, induce, entice, or coerce; (3) any individual who is younger than 18; (4) to engage in any sexual activity for which any person can be charged with a criminal offense, or attempting to do so. Id. Thomas was charged with attempt in this case because he could not have actually enticed a minor because his online chats were with an undercover police officer. Therefore, to prove attempt, "the government had to show that [defendant] took a 'substantial step' towards the commission of the ultimate crime, and that such step was more than mere preparation." Id. The issue here then is whether there was sufficient evidence that Thomas took a "substantial step" in each count towards the commission of the crime.

The court gave the jury the following instructions regarding the terms in the statute:

'Entice' is defined as beguiling by arousing hope or desire. A synonym of entice is lure.

'Induce' is defined as leading or moving by persuasion or influence. A synonym of induce is to prevail upon.

'Persuade' is defined as causing someone to do something by means of entreaty, argument, or reasoning. A synonym of persuade is convince.

Tr. of Jury Trial, R. Vol. 7 at 321. We have reviewed the evidence in this case, particularly the transcripts of the YAHOO! messaging sessions, and conclude that a reasonable jury had sufficient evidence to convict Thomas of both counts using the definitions set forth above.

As to the first count, it is apparent that Thomas initiated the sexual conversation by asking, in crude terms, to engage in oral sex moments after angelgirl12yo confirmed that she was a 12-year-old girl living near him. After angelgirl12yo questioned blackass_blk's boldness and said she was unsure about the proposal because she did not know him, Thomas insisted again that they have oral sex, and do it "now." Then, Thomas immediately asked the girl where she lived and suggested that they meet at the park, again stating that they should meet "now." See Munro, 394 F.3d at 869-70. Thomas took a substantial step in an attempt to induce, entice, and persuade by writing and sending his insistent messages.

We do not agree with Thomas's argument that "[w]ith particular regards to Count One, there is simply no evidence that Mr. Thomas intended to engage in anything more than harmless banter." Appellant's Opening Br. at 19. Thomas crossed the line from "harmless banter" to inducement the moment he began making arrangements to meet angelgirl12yo, notwithstanding the lack of evidence that he traveled to the supposed meeting place. See United States v. Bailey, 228 F.3d 637, 639-40 (6th Cir. 2000) (sufficient evidence of substantial step toward enticing minors where defendant sent e-mails to minors proposing oral sex but did not ever travel to meet the girls).

Moreover, sufficient evidence was presented for the jury to conclude that Thomas believed angelgirl12yo was 12 years old. Aside from her age being in her screen name, Special Agent Waters informed Thomas twice of her age, at one time asking, "you sure its [sic] cool that I am 12?" Appellee's App. at 2. Waters also gave Thomas a physical description of angelgirl12yo as being four feet, nine inches tall and seventy-seven pounds, the size of a typical preteen girl.

Finally, we conclude that there was sufficient evidence to find Thomas guilty of the second count of enticement, for all of the same reasons as mentioned above. The substantial step on this count is strengthened by the evidence of Thomas's venture to meet cheygirl13. We are therefore unpersuaded by Thomas's sufficiency of the evidence argument.

IV.	Vindictive prosecution

Thomas's final challenge to his conviction is that the United States engaged in vindictive prosecution by adding an additional count to the indictment after a mistrial was declared in the original trial.

We view a vindictive prosecution claim as a mixed question of law and fact and review a district court's resolution of the issue under the clearly erroneous standard. United States v. Wood, 36 F.3d 945, 946 (10th Cir. 1994). A defendant may not be penalized for exercising constitutional or statutory rights during the course of a criminal proceeding. United States v. Raymer, 941 F.2d 1031,1040 (10th Cir. 1991).

To punish a person because he has done what the law plainly allows him to do is a due process violation of the most basic sort, and for an agent of the State to pursue a course of action whose objective is to penalize a person's reliance on his legal rights is 'patently unconstitutional.'

Bordenkircher v. Hayes, 434 U.S. 357, 363 (1978) (quoting Chaffin v. Stynchcombe, 412 U.S. 17, 32 n.20 (1973) (citation omitted)). A defendant may demonstrate a due process violation by showing either (1) actual vindictiveness or (2) a realistic likelihood of vindictiveness which gives rise to a presumption of vindictiveness. Raymer, 941 F.2d at 1040. Once the defendant has made this showing, "the burden shifts to the prosecution to justify its charging decisions with legitimate, articulable, objective reasons." Wood, 36 F.3d at 946 (further quotation omitted).

We have examined the issue of prosecutorial vindictiveness in a context similar to Thomas's case, where the first trial resulted in a hung jury and the prosecution thereafter added charges to the indictment. We stated:

Generally, where, as here, a modification in a charging decision follows a mistrial occurring for neutral reasons, such as a hung jury, and without objection from the government, no presumption of vindictiveness is raised because there is no reason why the prosecutor would consider the defendant responsible for the need for a new trial. Nevertheless, the Supreme Court has refused to adopt per se rules in the prosecutorial vindictiveness context. Consequently, to determine whether a reasonable likelihood of vindictiveness exists, we must look to the totality of the objective circumstances surrounding the prosecutorial decision.

United States v. Contreras, 108 F.3d 1255, 1263 (10th Cir. 1997) (citations omitted).

Thomas argues that a realistic likelihood of vindictiveness exists because the prosecution had all of the evidence pertaining to the June 2003 chat before the first trial began and only charged him with it after he exercised his right to plead not guilty. He further asserts that the addition of the second charge resulted in an increase in his sentence.

Examining the totality of the circumstances, we cannot agree that there is a realistic likelihood of vindictiveness. The mistrial in Thomas's first case was declared because the jury could not reach a verdict, a neutral reason, and not because Thomas exercised a specific right.

Even if we assumed arguendo that a presumption of vindictiveness is appropriate here, the government has justified its decisions. At a hearing on this issue in the district court, the prosecutor told the court that he added the charge after speaking to the jury after the first trial was over. The jury members told the attorneys that they believed that Thomas's first chat with angelgirl12yo was the more egregious of the two. The prosecutor also told the court that when he subsequently decided to add the charge, he spoke to the probation office and was informed—erroneously, it was discovered much later—that the additional charge would not increase Thomas's punishment. Thomas has therefore not demonstrated that the superseding indictment was a result of prosecutorial vindictiveness.

B.

I.	Booker claim

United States v. Booker held that "[a]ny fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt." Booker, 125 S. Ct. at 756. District courts post-Booker are required to consult the Guidelines in fashioning sentences, but they are not required to sentence within the Guidelines range. United States v. Gonzalez-Huerta, 403 F.3d 727, 731 (10th Cir. 2005) (en banc). Constitutional Booker error occurs when the district court "re[lies] on judge-found facts . . . to enhance a defendant's sentence mandatorily." Id. By contrast, non-constitutional Booker error occurs when a sentencing court applies the Guidelines in a mandatory fashion, "even though the resulting sentence was calculated solely upon facts that were admitted by the defendant, found by the jury, or based upon the fact of a prior conviction." Id. at 731-32.

Thomas asserts only non-constitutional Booker error in his case. The facts upon which his sentencing enhancements were based—conviction on two separate counts and use of a computer in the commission of the crime—were established by the jury verdict5 and not by judicial fact-finding. He argues that he would have received a less harsh sentence had the district court been acting in a post-
Booker regime. He urges us to vacate his sentence and remand to the district court "for a sentencing which recognizes the mere advisory role of the Guidelines." Appellant's Opening Br. at 23.

The base offense level for Thomas's offense is 21 under United States Sentencing Commission, Guidelines Manual ("USSG") §§2G1.1(c)(3) and 2A3.2(b)(2)(B). Based upon the jury's findings that Thomas was guilty of two separate counts and that he used a computer in the commission of the offense, the district court assessed two, two-level increases under USSG §3D1.4 and USSG §2A3.2(b)(3), respectively. The district court declined to assess a third two-level increase for unduly influencing his purported victims. The defendant's total offense level was 25, and with a criminal history category of three, he was placed in a sentencing range of 70 to 87 months. The court sentenced him to 70 months, at the low end of the range, ten months more than the minimum of five years required by 18 U.S.C. § 2422(b).

The defendant objected to the two-level multiple-count upward adjustment in the PSR, arguing that the court should treat the two offenses as part of a "common scheme or plan" under USSG §3D1.2(b). At the sentencing hearing, the United States joined the defendant's objection to the multiple-count adjustment, which was based on the jury's conviction of Thomas on two counts. The court denied the objections, finding there was no evidence of a common scheme because the offenses were separated by a substantial time period. Nonetheless, when it imposed the sentence, the court stated:
[E]xamining the presentence report in this case, it is difficult to find a case where circumstances could have conspired more against the defendant for a harsh application of the guidelines in this case. . . . [I]t seems to me if you're trying to conceive of every harsh effect that could occur under the guidelines in a case, they have been applied and do, on their face, appear to apply to Mr. Thomas.

Because Thomas did not raise this argument below, we review for plain error. Booker, 125 S. Ct. at 769 ("[W]e expect reviewing courts to apply ordinary prudential doctrines, determining, for example, whether the issue was raised below and whether it fails the 'plain-error' test."); Gonzalez-Huerta, 403 F.3d at 732. "'Plain error occurs when there is (1) error, (2) that is plain, which (3) affects substantial rights, and which (4) seriously affects the fairness, integrity, or public reputation of judicial proceedings.'" Gonzalez-Huerta, 403 F.3d at 732 (quoting United States v. Burbage, 365 F.3d 1174, 1180 (10th Cir.), cert. denied, 125 S. Ct. 510 (2004)).

Thomas has met the first two prongs of the plain-error test: error occurred in this case, because the district court was operating under Guidelines it thought were mandatory, and that error was plain. See United States v. Dazey, 403 F.3d 1147, 1174-75 (10th Cir. 2005). However, because we conclude below that Thomas cannot meet the fourth prong of plain-error review, we need not decide whether his substantial rights were affected. See United States v. Cotton, 535 U.S. 625, 632-33 (2002); Gonzalez-Huerta, 403 F.3d at 736.

Under the fourth prong, the reviewing court may in its discretion correct an error if the error "seriously affects the fairness, integrity or public reputation of judicial proceedings." United States v. Olano, 507 U.S. 725, 732 (1993) (internal quotation marks omitted). The defendant bears the burden of showing that we should exercise our discretion. Dazey, 403 F.3d at 1178. "Where only non-
constitutional Booker error is at issue, this standard is especially demanding. We will not notice non-constitutional Booker error unless the defendant establishes the error is 'particularly egregious' and that our failure to correct it would result in a 'miscarriage of justice.'" United States v. Dowlin, Nos. 03-8038 & 03-8055, __ F.3d __, 2005 WL 1155882, at *18 (10th Cir. May 17, 2005).

We have identified several non-exclusive factors that might show that a defendant has satisfied the fourth prong: a sentence increased substantially based on a Booker error, a showing that the district court would likely impose a significantly lighter sentence on remand, a substantial lack of evidence to support the sentence the Guidelines required the district court to impose, and/or a showing that objective consideration of the 18 U.S.C. § 3553(a) factors warrants a departure from the sentence suggested by the Guidelines. Dowlin, 2005 WL 1155882, at *18 (citations omitted).

This case is a closer call than many. However, considering that we must find a "particularly egregious" error in a case of non-constitutional Booker error, this case does not warrant a remand. First, Thomas's sentence was not increased substantially based on the mandatory application of the Guidelines. Under § 2422(b), the mandatory minimum sentence is 60 months, and he was sentenced to just ten months more than the minimum.6 Cf. Dazey, 403 F.3d at 1178-79 (mandatory enhancement based on a judicial finding increased defendant's offense level by twenty levels, a consideration that helped show satisfaction of fourth prong). Second, we are not convinced the judge would impose a lighter sentence on remand. Although the district court mentioned the "harsh" effect of the Guidelines in this case, it further noted: "The court's [greater] concern . . . [is] that we are all familiar with [18 U.S.C. § 2422(b)] and its influence upon any departure on the part of the court." Tr. of Sentencing Hr'g, R. Vol. 9 at 24. The judge thus appears to feel bound more by the minimum sentence in the statute, which was unaffected by Booker, than by the application of the Guidelines. Third, as previously discussed, sufficient evidence supported conviction on both counts in this case; therefore, the sentence was supported by substantial evidence. Finally, there is evidence in the record that the district court considered the history and characteristics of the defendant at sentencing, see 18 U.S.C. § 3553(a)(1), including that the crime may have resulted from Thomas's boredom with life or "feeling that he was a victim of a system that made him care for the children while his wife was . . . away on [military] assignments." Tr. of Sentencing Hr'g, R. Vol. 9 at 27. Despite this, the court still sentenced Thomas to seventy months, which indicates that further objective consideration of the § 3553(a) factors would not warrant a departure. In sum, Thomas has not demonstrated that this is the "particularly egregious" case in which we should exercise our discretion to correct the Booker error.

CONCLUSION

For all of the foregoing reasons, we AFFIRM Thomas's conviction and sentence.
