Affirmed in part; vacated and remanded in part by published opinion. Judge WILKINSON wrote the opinion, in which Judge NIEMEYER and Judge KING joined.
The instant case touches upon the sovereign authority of the state and federal governments to create and enforce criminal laws. The Commonwealth of Virginia *194 charged defendant with state drug offenses, provided him with counsel, and subsequently dismissed the charges against him. After filing a federal criminal complaint, federal investigators gave defendant appropriate Miranda warnings and then questioned him outside the presence of his state-appointed lawyer about his involvement in federal drug crimes. Defendant contends that the incriminating statements he made during this interrogation should have been suppressed at his federal trial, because they were taken in violation of his Sixth Amendment right to counsel.
The Sixth Amendment right to counsel attaches only to the specific offense with which a defendant is formally charged.
See Texas v. Cobb,
I.
On the evening of October 1, 2003, state and federal law enforcement officers were conducting surveillance of an Econo Lodge Motel in Dumfries, Virginia. The officers had received a tip from a confidential source that cocaine would be delivered to the motel. They . observed Francisco Lara-Hernandez and another suspected drug trafficker enter the motel, and state law enforcement officers subsequently arrested them.
Special Agent Jordi Clop of the federal Bureau of Alcohol, Tobacco, and Firearms participated in this surveillance, and interrogated Lara-Hernandez after he was placed under arrest. Lara-Hernandez stated that he had recently returned to the hotel from North Carolina with approximately 500 grams of cocaine. He indicated to Clop that the cocaine was now across the street in Room 333 of the Days Inn Hotel. He also disclosed that three individuals, one wearing a red t-shirt, were in the room and that two vehicles, including a white truck, were associated .with the drug ring. Law enforcement officers observed defendant Samuel Constanza Alvarado (Alvarado), clad in a red t-shirt, exit Room 333 and climb into a white truck. State police officers arrested defendant upon his entering the truck.
Defendant did not speak English, but Agent Clop was fluent in Spanish. Agent Clop gave defendant his Miranda warnings, and defendant agreed to talk with Clop. From this conversation, Agent Clop determined that defendant was staying in Room 338 of the Days Inn, and received defendant’s permission to search the room. Law enforcement officers eventually recovered 250 grams of cocaine from Room 333 and a suitcase full of marijuana and a handgun from Room 338. In the early morning hours of October 2, 2003, defendant was transported to a police station in Prince William County, Virginia. Agent Clop interrogated him at the police station after defendant was again read his Miranda rights.
On October 2, the Commonwealth of Virginia issued arrest warrants for Alvarado. The Commonwealth charged him with both possession with intent to manufac *195 ture, sell, give, or distribute cocaine, see Va.Code Ann. § 18.2-248 (2004), and conspiracy to manufacture, sell, give, or distribute cocaine, see id. §§ 18.2-22, .2-248. According to the warrants, these charges concerned only the events on or about October 2, 2003. Defendant requested counsel, and the Commonwealth appointed him a lawyer. Virginia retained custody of defendant until December 5, 2003, when he had his preliminary hearing. At this hearing, the Commonwealth dismissed its charges against him.
On December 4, 2003, the day prior to Alvarado’s preliminary hearing in state court, federal agents had filed a federal criminal complaint against defendant, and requested a warrant for his arrest. This warrant was issued. See Fed.R.Crim.P. 3, 4(a). Agent Clop was present at the Prince William County courthouse when defendant’s state charges were dismissed, and immediately took him into federal custody. Defendant was subsequently transported to a Prince William County police station.
At the station, Alvarado told Agent Clop that he was glad to see him and wanted to give him his side of the story. Agent Clop interrupted defendant to give him Miranda warnings. In this conversation, defendant provided incriminating statements about his involvement in the drug conspiracy. Specifically, he described in detail the events of October 1-2, 2003. He also mentioned that he had gone on a previous trip to obtain cocaine from a source in North Carolina, and that he had been involved with other coconspirators in drug distribution since at least August 2003. After about forty-five minutes of questioning, Agent Clop took defendant before a judge to make his initial appearance.
On February 5, 2004, a grand jury indicted Alvarado on two counts. First, it charged him with conspiring to distribute 500 grams or more of cocaine, in violation of 21 U.S.C. §§ 841(a)(1), 846 (2000). According to the indictment, defendant conspired with at least three different individuals between August 2003 and October 2003. Second, the grand jury charged Alvarado with distributing cocaine on or about September 27, 2003, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2 (2000). Prior to trial, defendant moved to suppress all the incriminating statements made over the course of his conversations with Agent Clop. Defendant alleged that these statements were taken in violation of his Fifth and Sixth Amendment rights to counsel. The district court denied his motion, and found Agent Clop properly read defendant his Miranda rights.
Alvarado was tried in front of a jury between April 28 and May 4, 2004. At the trial, Agent Clop testified about the incriminating remarks that defendant made to him on December 5, 2003. The jury convicted defendant on both counts. Based on the Presentence Investigation Report, the district court enhanced defendant’s sentence on a number of grounds, including possession of a dangerous weapon and obstruction of justice. It ultimately sentenced him to 121 months on each count, with the sentences to run concurrently. Defendant appeals his convictions and sentence.
II.
Alvarado alleges that his inculpatory statements of December 5, 2003 should have been suppressed at his trial, because they were taken in violation of his Sixth Amendment right to counsel. * He initially contends that commencement of formal *196 proceedings on his state charges caused the Sixth Amendment right to counsel to attach to his federal charges as well, because the state and federal charges were the “same offense.”
We disagree. Since they arise from separate sovereigns, state and federal offenses are not the same for purposes of the Sixth Amendment right to counsel. This case, moreover, highlights the fact that different sovereigns often define and prosecute similar crimes in different ways. For even applying the traditional test to determine whether two conspiracies are the same, the state and federal offenses in this case are distinct.
A.
The Sixth Amendment provides that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to have the Assistance of Counsel for his defence.” U.S. Const. amend. VI. The right attaches only after the commencement of formal charges against a defendant.
See Moran v. Burbine,
A central feature of double jeopardy’s definition of offense is the “dual sovereignty doctrine.” Applying this doctrine, the Supreme Court has continually held that federal and state crimes are not the same offense, no matter how identical the conduct they proscribe.
See, e.g., Heath v. Alabama,
Because
Cobb
clearly indicates that the definition of offense is the same in the right to counsel and double jeopardy contexts,
Any other conclusion would be an affront to both state and federal sovereignty. “As every schoolchild learns, our Constitution establishes a system of dual sovereignty between the States and the Federal Government.”
Gregory v. Ashcroft,
We therefore cannot conclude that Virginia has functionally charged defendant with a federal crime, or vice versa. Virginia can no more define what constitutes a federal criminal offense than the federal government can promulgate Virginia’s criminal law. By virtue of their separate sovereignty, each may separately establish and enforce criminal laws in accordance with the Constitution’s commands. To suggest, as defendant does, that state and federal offenses are the same would strip both sovereigns of a central attribute of sovereignty in derogation of our federal design.
See Heath,
Alvarado nonetheless argues that if the dual sovereignty doctrine applies to the Sixth Amendment right to counsel, state and federal governments will manipulate their separate prosecutions to deprive the criminally accused of this right. But a defendant’s constitutional guarantees are not furthered by melding together federal and state sovereignty, and throwing overboard our federal system’s primary shield against government abuse.
See Gregory,
Both the state and federal governments, for example, must respect the Sixth Amendment right to counsel once each brings its own formal charges,
see Moran, 475
U.S. at 431,
*198
The circumstances before us illustrate that the operation of the Fifth and Sixth Amendment rights to counsel can adequately protect the criminally accused in each sovereign’s respective sphere. Defendant was formally charged with state offenses, and Virginia, following the dictates of the Sixth Amendment, provided him counsel. Defendant was later placed in federal custody, and the district court found that Agent Clop properly read him his
Miranda
rights. In fact, Agent Clop testified that Alvarado was eager to speak on December 5, and Clop had to interrupt him in order to provide the required warnings. And while federal and state law enforcement authorities did engage in joint investigation, such collaborative efforts can hardly be dispositive of government misconduct.
See Bartkus v. Illinois,
As the foregoing analysis indicates, we join those circuits that have employed the dual sovereignty doctrine in the Sixth Amendment context.
See United States v. Coker,
B.
The facts of this case are, moreover, illustrative of the broader principle that sovereigns can and. often do define and prosecute similar criminal conduct in divergent ways. Alvarado argues that since both the federal and state charges each included a count of conspiracy to distribute cocaine, the offenses must be the same. But, in fact, the state and federal governments elected to enforce their criminal laws differently, for they prosecuted defendant on separate conspiracies altogether.
The Double Jeopardy Clause prevents the government from splitting a single conspiracy into multiple offenses,
United States v. Cole,
(1) the time periods covered by the alleged conspiracies; (2) the places where the conspiracies are alleged to have occurred; (3) the persons charged as co-conspirators; (4) the overt acts alleged to have been committed in furtherance of the conspiracies, or any other descriptions of the offenses charged which indicate the nature and scope of the activities being prosecuted; and (5) the substantive statutes alleged to have been violated.
Cole,
Applying these factors, it is evident that the federal government was charging defendant with a much more extended and pervasive drug conspiracy than was the Commonwealth. In the first place, “the time periods covered by the alleged conspiracies,”
Cole,
The charges in the federal indictment and the evidence introduced at defendant’s federal trial also described a conspiracy broader in scope than the one alleged in the state charge.
See Cole,
Finally, the federal indictment charged defendant with conspiracy to distribute 500 grams of cocaine, whereas the Commonwealth did not designate a drug amount. The drug quantity was a substantive element of the federal crime.
See United States v. Promise,
One of the chief virtues of our system of dual sovereignty is that each sovereign can approach problems in divergent ways. Though sovereigns can criminalize similar conduct, they might have distinct objectives and resource constraints in doing so. Here, Virginia and the federal government, as separate sovereigns, have operated differently from one another in defining and prosecuting them separate conspiracy statutes. That the Commonwealth was charging defendant with conspiracy to distribute a finite amount of drugs on one day should not stop the federal government from prosecuting a more widespread conspiracy to distribute a greater amount of drugs over a several-month period.
III.
Alvarado also contends that, even if his state and federal offenses are distinct, his Sixth Amendment right to counsel still attached to his federal offenses, because law enforcement officers had filed a federal criminal complaint prior to his December 5 interrogation. We disagree with defendant’s contention because it misunderstands the essential nature of the Sixth Amendment right.
By its own terms, the Sixth Amendment applies to “criminal
prosecutions
” as opposed to criminal
investigations.
U.S. Const. amend. VI (emphasis added). The Supreme Court has thus repeatedly held that the Sixth Amendment right to counsel “attaches only at or after the initiation of adversary judicial proceedings against the defendant.”
United States v. Gouveia,
The filing of a federal criminal complaint does not commence a formal prosecution. Rather, the main reason a law enforcement officer files such a complaint is to establish probable cause for an arrest warrant.
See
Fed.R.Crim.P. 3, 4(a);
United States v. Moore,
This conclusion is buttressed by our previous holding that the right to counsel does not attach immediately after arrest and prior to arraignment.
See D Anjou,
It will come as no surprise, therefore, that our sister circuits have also held that the filing of a federal criminal complaint does not give rise to any Sixth Amendment right.
See, e.g., Beck v. Bowersox,
IV.
Lastly, defendant contends that the district court enhanced his sentence in violation of
United States v. Booker,
V.
For the foregoing reasons, we affirm defendant’s convictions, but vacate his sentence and remand to the district court for resentencing.
AFFIRMED IN PART; VACATED AND REMANDED IN PART.
Notes
Defendant has not appealed the district court’s conclusion that he was properly read his Mi randa rights in accordance with the Fifth Amendment.
