Ronald Frank Romero (“Romero”), an Indian, was arrested and indicted for aggravated assault on an Indian reservation against two non-Indians. The federal government asserted criminal jurisdiction under 18 U.S.C. § 1152. 1 After receiving instructions from the court that the Government must prove the non-Indian status of the alleged victims, the jury returned a verdict of guilty. Romero now appeals the district court’s refusal to grant his post-trial motion for judgment of acquittal, on the grounds that the government failed to offer any evidence that Romero’s alleged victims are not Indians. Romero argues that the non-Indian status of the victim of an Indian defendant charged under 18 U.S.C. § 1152 is an element of the crime. The Government responds by asserting that the non-Indian status of the victim in § 1152 cases is an exception to the statute which must be raised and established by the deifendant. Because the unopposed jury instructions making the non-Indian status of the victims an element of the Government’s case formed the law of this case, and because there was no evidence presented on the Indian or non-Indian status of the alleged victims, we reverse Romero’s convictions.
I.
All of the underlying events in this case occurred on the Nambe Pueblo Indian Reservation in New Mexico. On May 14, 1994, Romero approached the home of his neighbor, Lloyd Sanders (“Sanders”), to ask Sanders whether he had been involved with or knew anything about some, missing fence posts belonging to Romero’s father. At the time, Sanders and some acquaintances, Chris Herrera (“Herrera”) and Michael Padilla (“Padilla”), were working on a vehicle in front of Sanders’ home. During the course of their conversation, Romero accused Sanders of stealing his' father’s fence posts. Sanders denied stealing the posts. A shouting match ensued, culminating in Romero retrieving a bolt action rifle, re-entering Sanders’ property, pointing the rifle at Sanders, Herrera and Padilla, and screaming “I’ll kill you, I’ll kill you bastards.” The three men remained pinned behind the car for several minutes until Romero left.
Romero was subsequently arrested and indicted in federal court with two counts of aggravated assault with a deadly weapon under 18 U.S.C. § 1152, 18 -U.S.C. § 13, and N.M. Stat. Ann. § 30-3-2. 2 The indictment *1270 identified Sanders and Padilla as the victims. The indictment also expressly alleged that Romero was an Indian, that his victims were non-Indians, and that the crime occurred in Indian Country.
Sanders and Padilla testified at Romero’s jury trial but were never asked about their Indian or non-Indian status. At the conclusion of trial, the jury was instructed as follows:
For you to find the defendant guilty of aggravated assault by use of a' deadly weapon, as charged in COUNT I of the Indictment, the government must prove to your satisfaction beyond a reasonable doubt each of the following elements of the crime:
1. The Defendant threatened Lloyd Sanders with a rifle;
2.. This caused Lloyd Sanders to believe he was about to
be shot with the rifle;
3. A reasonable person in the same circumstances as Lloyd
Sanders would have had the same belief;
4. The defendant used a rifle, as a deadly weapon;
5. Lloyd Sanders is not an Indian;
6. The defendant is an Indian;
7. The incident occurred in Indian Country;
8. The incident occurred within the State and District of New Mexico on or about May 14,1994.
You are instructed that the United States and the Defendant have stipulated to the sixth element of this offense, and have stipulated that the place in which this offense is alleged to have occurred is within Indian country. You may accept the sixth element as being proved, and if you find that the incident occurred, you may accept the seventh element as being proved.
An identical instruction was given for Count II, which charged aggravated assault with a deadly weapon against Michael Padilla. It is clear from the record that the Government thought that the instructions included a stipulation that the alleged victims were non-Indians. The exchange between the court and the parties on this point went as follows:
THE COURT: Let’s talk about the jury instructions then while the jury is still out. Are there any objections to the instructions ?
[THE GOVERNMENT]: No, Your Honor. I did submit, based upon the stipulation, an additional instruction that clarifies that the Government need not prove that the victims were-non-Indians, and that it occurred in Indian Country. And so I feel assured that your clerk has incorporated that into the instructions.
THE COURT: Yes, she assured me she had. And I’m going to check right now and make sure and see what she’s added about that. Yes, at the end of the instruction that deals with the elements, she’s added, “You are instructed that the United States and the Defendant have stipulated to the sixth element of this offense, and have stipulated that the place in which this offense is alleged to have occurred is within Indian country. You may accept the sixth element as being proved, and if you find that the incident occurred, you may accept the seventh element as being proved.” Is that acceptable ?
[THE GOVERNMENT]: Yes, Your Hon- or.
[DEFENSE COUNSEL]: It is, Your Honor. I reviewed the jury instructions over lunch, and I have no objection to them.
Notwithstanding the Government’s belief to the contrary, it is apparent that Romero never stipulated to the non-Indian status of *1271 Sanders and Padilla, because the “sixth element” listed in the jury instructions dealt with the defendant Romero’s status as an Indian, and not the victims’ status as non-Indians, while the “seventh element” only dealt with the location of the offense being in “Indian Country.” There was no stipulation in the record pertaining to the “fifth element,” which is the one addressing the non-Indian status of the victims. Both the Government and the defense stated on the record that they had no objections to the instructions as they were read to them by the court. Neither side raised the issue of the non-Indian status of the victims during trial and neither side presented evidence on that issue.
During deliberations the jury asked if it was required to determine whether the victims were non-Indians. See United States v. Romero, No. CR 96-127 BB, at 2 (D.N.M. Nov. 12, 1996) (unpublished order). 3 After conferring with counsel for both sides, the court simply informed the jury that it was the jury’s job to decide “every element of the crimes charged.” Both the Government and the defense agreed to this response. The jury returned a verdict of guilty on both counts. See id. at 30.
Romero filed a motion for a judgment of acquittal under Fed.R.Crim.P. 29(c). Romero argued that the Government had failed to meet its burden of proving that the victims were non-Indians, thus he could not be convicted under 18 U.S.C. § 1152. The district court determined that notwithstanding the instruction, the non-Indian status was a matter of defense to be proved by the defendant. Accordingly, the district court denied the motion. See United States v. Romero, No. CR 96-127 BB, at 11. Romero was sentenced to 18 months imprisonment followed by one year of supervised release.
The parties in this case raise some very difficult federal Indian law questions, namely whether under 18 U.S.C. § 1152 the non-Indian status of the victim of an Indian defendant is an element of the crime or an exception to the statute, and if the victim’s non-Indian status is a statutory exception, then which party has the burden of raising and proving the Indian or non-Indian status of such victims. 4 However, we do not reach those issues because in this case the Government agreed to the jury instruction that the non-Indian status of the alleged victims is an element that must be proved by the Government in order to convict Romero of the offense, and this circuit’s law of the case doctrine now prevents us from reaching these intriguing questions. Instead, we are compelled to find that Romero’s conviction must be overturned because of the Government’s failure to prove an element of the crime as charged to the jury.
II.
This circuit’s adherence to our law of the case doctrine was recently acknowledged by the Supreme Court in
United States v. Wells,
— U.S. -,
The defendants argued that because the Government had agreed at trial to a jury instruction listing materiality of the false statement as an element of the crime the Eighth Circuit’s law of the case doctrine precluded the Government from arguing to the contrary on appeal.
See id.
In its holding the Court noted that “several Courts of Appeals have ruled that when the Government accepts jury instructions treating a fact as an element of an offense, the ‘law of the ease’ doctrine precludes the Government from denying on appeal that the crime includes [that] element.”
Id.
(citing
United States v. Killip,
As the Supreme Court pointed out in
Wells,
the. rule in this circuit is that agreed-upon jury instructions form “the law of the case, and the evidence must conform to them to support the conviction.”
United States v. Cronic,
This court held that although “specific intent is not an element of § 751(a), specific intent became the law of the case when the Court gave [its instruction].” Id. We then upheld the conviction on the ground that at trial the Government had presented sufficient evidence of Woodring’s specific intent to escape. See id. 6
We again encountered the law of the case doctrine in
Killip,
We rejected the Government’s argument, holding that, the unchallenged instructions, and not the case law, formed the law of the ease. See id. at 1548. Because the Government had presented sufficient evidence of agreement to commit two predicate acts only on the part of one of the defendants, Krout, we reversed the conviction of co-defendant Teague. See id. at 1548-49. 7
In
Michaud v. United States,
Michaud is distinguishable from Woodring and Killip, as well as from the case before us, for the following reasons: (1) the law of the case doctrine" was not at issue in Mi-chaud, rather the issue was whether the jury instructions impermissibly confused the jury as to the issue before it; (2) the “false issue” in question related to the proper definition of the language of an element, not to a separate and distinct element that the Government bound itself to prove by agreeing to the jury instructions; and (3) the sufficiency of the, evidence to support the conviction was not raised by the defendant. 8
In sum, the case law in this circuit clearly establishes that we adhere to the law of the ease doctrine, whereby the Government is required to prove all elements put forth in unchallenged instructions to the jury, even if the Government would not, under law, be otherwise required to do so.
See Cronic,
*1274 III.
As discussed above, the Government admits that it presented no evidence of the non-Indian status of Sanders and Padilla at trial. We decline to accept the Government’s suggestion that the jury could have determined that Sanders and Padilla, both of whom testified before the jury, were non-Indians on the basis of their names, appearance, speech, and testimony that they did not grow up on the Nambe Pueblo. Not only did the jury’s question to the court indicate that the jury felt it had been presented with insufficient information upon which to determine the non-Indian status of Sanders and Padilla, the Government’s suggested basis for such a determination does not obviously satisfy the complex legal definition of Indian status.
See United States v. Rogers,
Because the Government agreed to the court’s instructions that the non-Indian status of Sanders and Padilla was an element necessary for conviction, and because the Government did not offer any proof as to the non-Indian status of those individuals, we have no choice but to reverse Romero’s convictions.
See United States v. Perez,
IV.
For the reasons stated above, the convictions of Ronald Frank Romero under 18 U.S.C. § 1152 are REVERSED.
Notes
. 18 U.S.C. § 1152 (1984) reads, in full:
Except as otherwise expressly provided by law, the general laws of the United States as to the punishment of offenses committed in any place within the sole and exclusive jurisdiction of the United States, except the District of Columbia, shall extend to the Indian country.
This section shall not extend to offenses committed by one Indian against the person or property of another Indian, nor to any Indian committing any offense in the Indian country who has been punished by the local law of the tribe, or to any case where, by treaty stipulations, the exclusive jurisdiction over such offenses is or may be secured to the Indian tribes respectively.
. 18 U.S.C. § 1152, also known as the Indian Country Crimes Act, establishes federal jurisdiction over criminal acts against the general laws of the United States committed in Indian Country, subsequent to the three listed exceptions. These exceptions recognize and preserve tribal sovereignty over matters of central importance to tribal self-government.
See United States v. Wheeler,
18 U.S.C. § 13 (West Supp.1997), known as the Assimilative Crimes Act,
inter alia,
makes
*1270
punishable under federal law any act done in Indian Country that would be punishable if done within the jurisdiction of the state where such land is situated according to the terms of that state’s criminal laws.
See Williams v. United States,
Aggravated assault is defined by N.M. Slat. Ann. § 30-3-2 as “unlawfully assaulting or striking at another with a deadly weapon.” In turn, assault is defined in the New Mexico statutes as "any unlawful act, threat or menacing conduct which causes another person to reasonably believe that he. is in danger of receiving an immediate battery....” N.M. Stat. Ann. § 30-3-1.
. The note from the jury read as follows: "We have some jurors who say that Lloyd Sanders and Michael Padilla have not been proven to be non-Indian, despite the statement in the instructions. Do we, as jurors, have to decide this ?” (Tr. Rec. Vol. 1 at 27.)
.
Compare United States v. Torres,
. In doing so the Court held that a circuit's adoption of a rule such as the law of the case doctrine:
[C]annot dispositively oust this Court’s traditional rule that we may address a question properly presented in a petition for certiorari if it was "pressed [in] or passed on” by the Court of Appeals, United States v. Williams,504 U.S. 36 , 42,112 S.Ct. 1735 , 1739,118 L.Ed.2d 352 (1992) (internal quotation marks and emphasis omitted). Accordingly, we have treated an inconsistency between a party's request for a jury instruction and its position before this Court as just one of several considerations bearing on whether to decide a question on which we granted certiorari. See Springfield v. Kibbe,480 U.S. 257 , 259-260,107 S.Ct. 1114 , 1115-16,94 L.Ed.2d 293 (1987). Here, it seems sensible to reach the question presented.
Wells,

Woodring
served as 'a strong basis for the rationale underlying the Fifth Circuit's application of the law of the case doctrine in
Spletzer. See Spletzer,
