The United States of America challenges the district court’s 1 order granting Andrew Red Bird’s motion to suppress a statement obtained in violation of the Sixth Amendment. We affirm.
I. Background
On September 11, 2000, Red Bird was charged by criminal complaint and arraigned on a rape charge in the Rosebud Sioux Tribal Court. He pled not guilty. The tribal court appointed an attorney for him, and he was represented in the arraignment proceedings by a Rosebud Sioux Public Defender, a licensed attorney in the state of South Dakota who is admitted to practice in the United States District Court for the District of South Dakota and the United States Court of Appeals for the Eighth Circuit. The constitution of the Rosebud Sioux Tribe guarantees members the right to an attorney in tribal court, and the tribe will pay for an attorney if a defendant is indigent.
Sometime before November 28, 2000, tribal authorities informed FBI Special Agent D. Joseph Weir of the rape allegedly committed by Red Bird. The crime of rape is subject to federal jurisdictiоn when it is perpetrated by an Indian in Indian Country. See 18 U.S.C. § 1153 (2000). On November 28, Grace Her Many Horses, a Rosebud Sioux Tribal Investigator, assisted Weir in locating Red Bird so that Weir could interview Red Bird concerning the same rape allegation that was pending in tribal court. 2 The district court found that both Weir and Her Many Horses knew about the tribal rape сharge and Red *712 Bird’s legal representation, but neither one contacted Red Bird’s attorney or received the attorney’s permission to conduct the interview.
When Her Many Horses and Weir located Red Bird, he informed them that his lawyer had advised him not to make a statement. He claimed, however, that he had nothing to hidе so he would make “one statement and one statement only.” Weir and Her Many Horses interviewed Red Bird at his house, but Weir demanded that none of Red Bird’s family members be present. Weir read Red Bird his Miranda rights, allowed Red Bird to read the advice of rights form, and Red Bird signed the waiver portion of that form. After the agents interviewed Red Bird, they аsked him to submit to buccal swabs for a saliva specimen. Red Bird consented, and a saliva sample was taken at the Rosebud Comprehensive Health Facility. DNA testing of this specimen allowed authorities to identify semen found on the victim’s clothing as that of Red Bird.
On April 18, 2001, a federal indictment was filed charging Red Bird with four counts of aggrаvated sexual abuse. The federal indictment charges the same date, victim, location and rape as the tribal rape charge.
On May 15, 2001, Red Bird filed a motion asking the district court to: (1) suppress his statement made to Weir and Her Many Horses, and (2) suppress the saliva evidence taken following the interview. Red Bird assertеd that his statement was taken in violation of the Sixth Amendment, or in the alternative, that his statement was involuntary. He also argued that the saliva sample, which was used to obtain DNA test results, was inadmissible as “fruit of the poisonous tree.” A hearing was held before a United States Magistrate Judge 3 on May 29, 2001. The magistrate recommended that Red Bird’s motion be granted in part, finding that his statements should be suppressed because the interview violated Red Bird’s Sixth Amendment right to counsel. The magistrate also recommended that the motion be denied in part, holding that his statement and consent to provide evidence was voluntary and that the evidence obtained following the statement was admissible under the inevitable discovery exception to the exclusionary rule.
Both the government and Red Bird submitted objections to the magistrate’s Report and Recommendation, but the district court adopted it. The court found that the federal and tribal charges were identical, that Weir and tribal authorities were working in tandem, and that Weir knew counsel had been appointed to Red Bird at the time of the rape charge. Upon making these findings, the district court held that Red Bird’s Sixth Amendment right to counsel attached when he was arraigned on the rape charges in tribal court and that the subsequent interview violated Red Bird’s Sixth Amendment right to counsel. The court, therefore, ordered that Red Bird’s statements be suppressed in the federal prosecution. The district court also upheld the magistrate’s decision that the buccal swab/DNA evidence was admissible because it inevitably would have been discovered by lawful means.
The government appeals the district court’s order suppressing Red Bird’s statements. 4
*713 II. Discussion
The first issue we must address is whether we may apply Sixth Amendment analysis in this case. We note at the outset that it is common for Indian tribal governments and federal authorities to cooperate in the investigation and prosecution of crimes committed on reservations. The Bill of Rights аnd the Fourteenth Amendment, however, do not apply directly to tribes.
See Santa Clara Pueblo v. Martinez,
Although the Sixth Amendment does not constrain the conduct of tribal officials, it does apply to the conduct of federal officials. “The line of authority ... exempting Indian tribes from Constitutional provisions addressed specifically to State or Federal Governments ... does not relieve State and Federal Governments of their obligations to individual Indians under these provisions.”
Santa Clara Pueblo,
“Whatever else it may mean, the right to counsel ... means at least that a person is entitled to the help of a lawyer at or after the time that judicial proсeedings have been initiated against him ‘whether by way of formal charge, preliminary hearing, indictment, information, or arraignment.’ ”
Brewer v. Williams,
Massiah
explains that the period between an indictment and a trial, the period
*714
of “ ‘thorough-going - investigation and preparation,’ ” is perhaps the most critical period of the prоceedings and a defendant is “ ‘as much entitled to [counsel’s aid] during that period as at the trial itself.’ ”
Massiah,
Indeed, after a formal accusation has been made — and a person who has previously been just a “suspect” has become an “accused” within the meaning of the Sixth Amendment — the constitutional right to the assistance of counsel is of such importance that the police may no longer employ techniques for eliciting information from an uncounseled defendant that might have been entirely proper at an earlier stage of their investigation.
Michigan v. Jackson,
The analysis in Massiah applies tо the case at hand. At the time that Red Bird was interviewed, he had been indicted and had been appointed an attorney who was licensed to serve him in both tribal and federal court. Tribal authorities informed Agent Weir of the tribal indictment and the possible violation of federal law. Agent Weir then worked in tandem with the tribal criminal investigator to deliberately elicit information from Red Bird, knowing that Red Bird had been indicted in an adversarial proceeding for the same charge and that Red Bird was represented by an attorney on that charge. This is not a case where the federal agent was unaware of the tribal charge or unaware of the defendant’s representation by counsel. Rather, it is a case where two sovereigns worked together to investigate conduct that violates the laws of both. 6
We find that as a result of the way that tribal and federal authorities cooperated in connection with these charges, Red Bird’s indictment in tribal court inherently led to his prosecution in federal court. Considering the close working relationship between tribal and federal authorities in this case, to deny Red Bird the right to counsel after the tribal indictment would deprive him of an attorney at one of the most critical stages of the proceedings against him. Therefore, we hold that Red Bird is entitled to the protections of the Sixth Amendment.
Next, we consider the government’s argument that Red Bird’s Sixth Amendment right did not attach. The government first asserts that the tribal and federal criminal complaints do not charge the same offense. The Sixth Amendment right to counsel is offense specific.
McNeil v. Wisconsin,
To determine whether the tribal and federal complaints charge the same offense, we look to
Texas v. Cobb,
The government also asserts that Red Bird’s right did not attach because the tribal arraignment was not an adversarial judicial proceеding. The Sixth Amendment right to counsel attaches at the commencement of adversarial proceedings against a defendant.
Kirby v. Illinois,
Unlike many tribes, the Rosebud Sioux Tribe has developed an adversarial criminal justice system. As the district court noted, proceedings in the Rosebud judicial system do not operate as family gatherings and counseling sessions.

Finally, the government argues that even if Red Bird had a Sixth Amеndment right to counsel at the time of the interview, his statements should not be excluded because

III. Conclusion
For the reasons set forth above, we affirm the decision of the district court to suppress Red Bird’s statement.
Notes
. The Honorable Charles B. Kornmann, United State District Court for the District of South Dakota.
. The district court found that "[i]t is undisputed that both the federal government and the tribe, two sovereigns, were cooperating in the investigation and charging of the defendant.”
United States v. Red Bird,
. The Honorable Mark A. Moreno, United States Magistrate Judge for the District of South Dakota.
. Our court has jurisdiction over this appeal pursuant to 18 U.S.C. § 3731 (2000), which allows the government to appeal a district court’s exclusion of evidence in a criminal proceeding before a verdict is issued if the *713 United States attorney certifies that the appeal is not taken for purpose of delay and that the evidence is substantial proof of a fact material in the proceeding. The portion of the interview that the government deems mоst critical is an alleged admission by Red Bird of having been with the victim but a denial of having had intercourse with her.
The district court’s holdings that Red Bird’s statement was voluntary and that the DNA evidence is admissible are not at issue in this appeal.
. Indian tribes, although limited sovereigns, have retained the right to try and punish individuals who transgress their laws. This right is not derived from thе federal government but is inherent in the tribes' sovereignty.
See United States v. Wheeler,
. We note that Indian tribes retain sovereignty of a “unique and limited character.”

. The arraignment was continued to allow Doherty to contact an attorney.
