      Petitioner-Appellant Mirella Ivonne Avila-Ramos appeals from the district

court’s denial of habeas corpus relief from an extradition certification order. On
appeal, she challenges the magistrate judge’s and district court’s probable cause

rulings. We have jurisdiction under 28 U.S.C. §§ 1291 and 2253, and we affirm

because the magistrate judge adequately found probable cause that Ms. Avila-Ramos

committed aggravated homicide, the crime identified in the extradition request.



                                     Background

      Ms. Avila-Ramos is wanted for aggravated homicide in Chihuahua, Mexico.

Supp. R. 26. According to the warrant for her arrest, Ms. Avila-Ramos plotted with

Arturo Heriberto Herrera Rey, her paramour, to murder her husband. 

Ms.

Avila-Ramos’s husband, who had survived an earlier attempt on his life, was on his

way to a hospital appointment when he was attacked and killed by a hired gun. 

38. An investigation implicated Ms. Avila-Ramos and Mr. Rey in the hit, and

Mr. Rey was convicted of aggravated homicide for his involvement in the crime.

Def.’s Ex. B at 32, In re Extradition of Avila-Ramos, No. 1:15-mj-01087-NYW (D.

Colo. Oct. 7, 2015), ECF No. 178-1. Now, Mexico requests Ms. Avila-Ramos’s

extradition from the United States to face charges for her participation in the plot. 

–21; Supp. R. 43.

      After a hearing, a magistrate judge certified Ms. Avila-Ramos as extraditable.

In re Extradition of Avila-Ramos, No. 1:15-mj-01087-NYW (D. Colo. May 6, 2016),

ECF No. 181. Among the magistrate judge’s findings was that there was sufficient

evidence to establish probable cause that Ms. Avila-Ramos committed aggravated

homicide. 

Ms. Avila-Ramos filed a petition for a writ of habeas corpus


                                           2
challenging the extradition certification order, 

, which the district court denied,

Avila-Ramos v. Kammerzell, 

, 1204 (D. Colo. 2017). In

upholding the magistrate judge’s probable cause determination, though, the district

court characterized Ms. Avila-Ramos’s offense as conspiring to murder her husband

(rather than as aggravated homicide). See 

      On appeal, Ms. Avila-Ramos argues that (1) a finding of probable cause for

conspiring to commit murder does not subject her to extradition for aggravated

homicide, the offense identified in the extradition request, and (2) the magistrate

judge based her probable cause determination on inadequate evidence.



                                       Discussion

      Habeas review of a probable cause determination in an extradition proceeding

is limited to the narrow issue of “whether there was any evidence warranting the

finding that there was reasonable ground to believe the accused guilty.” Peters v.

Egnor, 

, 717 (10th Cir. 1989) (quoting Fernandez v. Phillips, 

, 312 (1925)). In other words, the petitioner’s appeal “must fail if there is ‘any

evidence of probable cause.’” 

v. U.S. Marshal, 

,

501 (9th Cir. 1987), abrogated on other grounds by United States v. Wells, 

(1997)). On appeal, we “review the district court’s legal determinations de novo

and its findings of fact for clear error.” Smith v. United States, 

, 965

(10th Cir. 1996). Here, where the district court made no additional factual findings

concerning probable cause, our review of the district court’s judgment is purely de


                                            3
novo. See Santos v. Thomas, 

, 1001 (9th Cir. 2016) (“We review the

district court’s judgment de novo. In this context, that means that, with respect to the

extradition court, we stand in the same position as did the district court.” (citation

omitted)).

A.    The Magistrate Judge Found Probable Cause for the Crime Identified in the
      Extradition Request

      Ms. Avila-Ramos first argues that she is not extraditable because probable

cause was not found for the crime identified in the extradition request. The

extradition request charges her with aggravated homicide, but she contends that

probable cause was found for conspiracy to commit murder, which allegedly

constituted an impermissible alteration of the charges underlying the extradition

request.

      Ms. Avila-Ramos did not raise this argument in her habeas petition to the

district court, presumably because the magistrate judge did find probable cause that

Ms. Avila-Ramos committed aggravated homicide, the crime identified in the

extradition request. See In re Extradition of Avila-Ramos, slip op. at 19 (“This court

CERTIFIES to the United States Secretary of State that Respondent Mirella Ivonne

Avila Ramos is extraditable for the charged offense of aggravated homicide pursuant

to 18 U.S.C. § 3184 . . . .” (emphasis added)). The sole basis for her argument is that

the district court inexplicably characterized her offense as conspiring to murder her

husband, not as aggravated homicide. See 

(“The United Mexican States (‘Mexico’) accuse Petitioner Mirella Ivonne Avila-



                                            4
Ramos (‘Avila-Ramos’) of conspiring to have her husband murdered in Mexico.”

(emphasis added)); 

(upholding the magistrate judge’s finding of probable

cause that Ms. Avila-Ramos committed the offense of “conspiring to murder her

husband” (emphasis added)).

      Ms. Avila-Ramos is not entitled to relief, however, simply because the district

court mischaracterized the charge against her. The scope of our review is limited to

the sufficiency of the magistrate judge’s order, which we review without deference to

the district court’s legal determinations. See 

; 

. As the magistrate judge unambiguously found probable cause for the

offense identified in the extradition request (aggravated homicide), the charges

contained in the extradition request have not been altered.1

B.    The Magistrate Judge’s Probable Cause Determination Was Adequate

      Next, Ms. Avila-Ramos contests the adequacy of the magistrate judge’s

probable cause determination. She argues that (1) although the government produced

evidence that she conspired to kill her husband, it did not produce any evidence that



      1
         Ms. Avila-Ramos also invokes the “rule of specialty,” stating that it “does
not allow for trial on” charges other than those identified in the extradition request.
Aplt. Br. at 10. The rule of specialty in the extradition treaty between the United
States and Mexico provides that “[a] person extradited under the present Treaty shall
not be detained, tried or punished in the territory of the requesting Party for an
offense other than that for which extradition has been granted.” Extradition Treaty
Between the United States of America and the United Mexican States art. 17, Mex.-
U.S., May 4, 1978, 31 U.S.T. 5059. Ms. Avila-Ramos has misapplied the rule, “as it
relates to prosecution rather than extradition.” 

n.9. Whether
Ms. Avila-Ramos’s eventual prosecution violates the rule of specialty is for the
Mexican courts to address.

                                           5
she was directly responsible for her husband’s death and (2) the magistrate judge

relied on improper evidence, namely the criminal proceedings against Mr. Rey.

      The first issue is whether, as a matter of law, the magistrate judge could have

found probable cause that Ms. Avila-Ramos committed aggravated homicide from

the evidence in the extradition request.2 Ms. Avila-Ramos argues that the evidence

supports, at most, a conspiracy to kill her husband, which is a distinct offense from

aggravated homicide. But Ms. Avila-Ramos ignores the fact that conspiring to

commit a crime is also a theory of liability for the substantive offense. See United

States v. Bowen, 

, 1077 & n.10 (10th Cir. 2008) (describing Pinkerton

coconspirator liability); see also United States v. Zackery, 

, 649 (8th

Cir. 2007) (holding that a defendant does not need to be charged as a conspirator to

be convicted of a substantive offense based on Pinkerton coconspirator liability).

The same holds true for aiding and abetting the commission of a crime. See 

& n.10; see also United States v. Day, 

, 722 (4th Cir.

2012) (ruling that “aiding and abetting is a theory of liability, not a separate offense,”

and that the rule of specialty in the extradition treaty between the United States and


      2
         The extradition treaty between the United States and Mexico provides that
extradition may be granted only if, according to the laws of the requested country,
there would be sufficient evidence to bring the accused to trial if he or she had
committed the offense in the requested country. Extradition Treaty art. 3.
Accordingly, the relevant inquiry is whether there would be sufficient evidence under
U.S. law to bring Ms. Avila-Ramos to trial if she had committed the offense in the
United States, the requested country. See Eain v. Wilkes, 

, 507–08 (7th
Cir. 1981) (concluding that nearly identical language in the extradition treaty
between the United States and Israel “require[d] a finding of probable cause under
federal law”).

                                            6
Mexico does not require the requesting state to specify a particular theory of

liability). As a result, the government did not need to produce evidence that Ms.

Avila-Ramos was directly responsible for her husband’s death; it could produce

evidence of coconspirator or aiding and abetting liability instead.

      Here, either theory supports the magistrate judge’s probable cause

determination. The extradition request contains sworn statements from family

members, a private investigator, forensics experts, and Mexican law enforcement

officers, which together allege that Ms. Avila-Ramos (1) was having an affair with

Mr. Rey, who arranged the assassination; (2) paid the gunman by helping him

burglarize her husband’s house; and (3) reported her husband’s whereabouts to Mr.

Rey to facilitate the assassination. See 

–27; Supp. R. 146–242, 253–61. In

short, the request alleges that Ms. Avila-Ramos was part of — and assisted in — an

agreement to kill her husband. Consequently, the evidence provides grounds to

believe that Ms. Avila-Ramos is liable for her husband’s death either as a

coconspirator or as an aider and abettor.

      The second issue is whether the magistrate judge relied on improper evidence

when determining probable cause. When reviewing the sufficiency of evidence in an

extradition proceeding, a magistrate judge’s role is “to determine whether there is

competent evidence to justify holding the accused to await trial, and not to determine

whether the evidence is sufficient to justify a conviction.” 

(quoting Collins v. Loisel, 

, 316 (1922)). Notably, the Federal Rules of

Evidence do not apply to extradition proceedings, Fed. R. Evid. 1101(d)(3), and 18


                                            7
U.S.C. § 3190 provides that properly authenticated depositions, warrants, or other

papers are admissible evidence. Ms. Avila-Ramos does not challenge the

authenticity of the documents in Mexico’s extradition request. She argues, however,

that the magistrate judge improperly relied on documents from Mr. Rey’s trial in

Mexico.

      In Mr. Rey’s trial, the Mexican court found that Mr. Rey and Ms. Avila-Ramos

“undoubtedly” conspired to kill her husband. Def.’s Ex. B at 22–23. According to

the magistrate judge, this evidence was “the most persuasive support for the finding

of probable cause,” particularly because the trial was conducted in Spanish, thereby

addressing Ms. Avila-Ramos’s concerns about translation and reliability issues in the

extradition request’s documents. In re Extradition of Avila-Ramos, slip op. at 17.

Ms. Avila-Ramos likens this evidence to a conviction rendered in absentia and

contends that such a conviction should be treated merely as a charge, which does not

establish probable cause by itself. Her argument is unavailing, though, for two

reasons.

      First, her analogy to an in absentia proceeding is inapt. A trial in absentia is a

trial held without the accused. Trial In Absentia, Black’s Law Dictionary (10th ed.

2014). Mr. Rey was present for his trial, and the Mexican court convicted him, not

Ms. Avila-Ramos. Therefore, the proceedings were not in absentia, and the policy

reasons for treating them as a charge (rather than as evidence) do not apply. Instead,

the proceedings are more accurately categorized as hearsay: they contain out-of-court

statements that are being offered for the truth therein, and Ms. Avila-Ramos did not


                                           8
have the opportunity to cross-examine the declarants. As the rule against hearsay

does not apply in extradition proceedings, see Fed. R. Evid. 1101(d)(3), the

magistrate judge could properly consider the criminal proceedings against Mr. Rey.

      Second, Ms. Avila-Ramos’s appeal fails if there was any evidence of probable

cause, see 

, and the criminal proceedings against Mr. Rey

were not the only evidence that the magistrate judge considered. The magistrate

judge cited a variety of evidence from the extradition request, including (1) text

messages, (2) phone records, and (3) statements of a private investigator, a Mexican

law enforcement officer, and Mr. Rey. In re Extradition of Avila-Ramos, slip op. at

15–17. This evidence independently supported the magistrate judge’s probable cause

finding, and Ms. Avila-Ramos’s appeal consequently fails.

      AFFIRMED.
