MURPHY, Circuit Judge.
I. INTRODUCTION
Following his arrest on and arraignment for various drug and firearm possession charges, defendant Mario Toombs remained incarcerated for approximately twenty-two months before his trial began. During this time period, the district court granted seven continuances under the ends-of-justice provision of the Speedy Trial Act, 18 U.S.C. § 3161(h)(7) (“ends-of-justice continuances”). In a motion to dismiss, Toombs claimed the district court failed to make the requisite factual findings when it granted the ends-of-justice continuances, and therefore over seventy non-excludable days had passed between his arraignment and trial in violation of the Speedy Trial Act, 18 U.S.C. § 3161(c)(1). The district court denied the motion to dismiss, concluding it had made the factual findings required by the Speedy Trial Act for each of the continuances. The matter then proceeded to trial, and Toombs was convicted on all counts. On appeal, Toombs challenges, inter alia, the denial of his motion to dismiss. Exercising jurisdiction pursuant to 28 U.S.C. § 1291, we affirm in part, reverse in part, and remand for proceedings consistent with this opinion.
II. BACKGROUND
On April 26, 2006, Toombs and co-defendant Arlynda Osborn were indicted for various firearm and drug possession offenses. Toombs was arraigned on May 2, 2006, and remained incarcerated for approximately twenty-two months preceding his trial, which began on March 4, 2008. During the time period between Toombs’s arraignment and trial, the district court granted nine continuances, the latter seven of which were granted pursuant to the ends-of-justice provision of the Speedy Trial Act:
1. On May 22, 2006, defense counsel moved for additional time to file pretrial motions, contending he had not yet received discovery. The motion contained a limited waiver of Toombs’s Speedy Trial Act rights and stated the government had no objection to the continuance. In its order granting the motion, the district court excluded the time from May 22, 2006 to July 10, 2006, for purposes of the Speedy Trial Act pursuant to 18 U.S.C. § 3161(h)(1)(D).
2. On June 19, 2006, defense counsel moved again for additional time to file pretrial motions, contending counsel had not yet received discovery. The motion contained a limited waiver of Toombs’s Speedy Trial Act rights and stated the government had no objection to the request. In its order granting the motion, the court excluded the time from June 19, 2006 to July 31, 2006, for purposes of the Speedy Trial Act pursuant to 18 U.S.C. § 3161(h)(1)(D).1
3. On August 31, 2006, defense counsel filed a motion to continue on the grounds that new counsel needed additional time to review discovery and prepare for trial.2 On September 5, 2006, [1266]*1266the district court, for good cause, granted the motion to continue, stating that the ends of justice outweighed the best interest of the public and the defendant in a speedy trial under 18 U.S.C. § 3161(h)(7).3 The district court excluded the time from August 31, 2006 to November 6, 2006, the new trial date, for purposes of the Speedy Trial Act.
4. On October 23, 2006, the • government filed a motion to continue contending it was making a concerted effort to locate and arrest codefendant Osborn. The motion stated the evidence against Toombs would be largely the same as that against Osborn, who remained a fugitive. The motion further stated counsel for Toombs had no objection to the continuance. The district court granted the continuance on October 27, 2006, finding that the basis of the continuance was proper under the provisions of 18 U.S.C. § 3161(h)(6) and the ends of justice outweighed the best interest of the public and the defendant in a speedy trial under 18 U.S.C. § 3161(h)(7). The court excluded the time from October 23, 2006 to February 5, 2007, the new trial date, for purposes of the Speedy Trial Act.
5. On January 23, 2007, defense counsel filed a motion to continue stating he needed more time to prepare for trial due to three other eases for which he was scheduled to appear in the weeks before Toombs’s scheduled trial date. The motion stated the government did not object to the continuance. The district court granted the motion on February 5, 2007, stating the ends of justice served by granting the continuance outweighed the best interest of the public and the defendant in a .speedy trial under 18 U.S.C. § 3161(h)(7). The court excluded the time from January 23, 2007 to May 7, 2007, the new trial date, for purposes of the Speedy Trial Act.
6. On April 30, 2007, defense counsel filed a motion to continue stating additional discovery had recently been disclosed requiring additional investigation. The motion further stated the government had no objection to the continuance. On May 1, 2007, the district court issued an order granting the continuance “in order for the defense to adequately prepare and for the reasons stated in the motion.” The order further stated the ends of justice outweighed the best interest of the public and the defendant in a speedy trial pursuant to 18 U.S.C. § 3161(h)(7). The court excluded the time from April 30, 2007 to July 9, 2007, the new trial date, for purposes of the Speedy Trial Act.
[1267]*12677. On July 5, 2007, defense counsel filed another motion to continue based upon newly disclosed discovery. The motion was nearly identical to the April 30, 2007 motion. On July 10, 2007, in an order identical to the May 1, 2007 order with the exception of the dates provided, the district court granted the continuance “in order for the defense to adequately prepare and for the reasons stated in the motion.” The order further stated the ends of justice outweighed the best interest of the public and the defendant in a speedy trial pursuant to 18 U.S.C. § 3161(h)(7). The court excluded the time from July 5, 2007 to September 4, 2007, the new trial date, for purposes of the Speedy Trial Act.
8. On August 14, 2007, Toombs retained the services of Melanie Morgan, who entered her appearance as counsel of record. On August 24, 2007, defense counsel filed a motion to continue which detailed the current status of the case and indicated she needed additional time to review discovery and prepare for trial. On August 28, 2007, the district court issued an order granting the continuance. The order stated the ends of justice outweighed the best interest of the public and the defendant in a speedy trial pursuant to 18 U.S.C. § 3161(h)(7). The court excluded the time from August 24, 2007 to November 5, 2007, the new trial date, for purposes of the Speedy Trial Act.
9. On October 24, 2007, the government filed a motion to continue on the grounds that Osborn had been arrested and was in federal custody en route to Kansas. Toombs filed a motion to sever on October 29, 2007, arguing the lengthy delay that would be caused by a joint trial was unreasonable and asserting his Sixth Amendment right to a speedy trial. A hearing was held and the district court denied the motion to sever. The district court then issued an order granting the government’s requested continuance. The order stated that the basis of the continuance was proper under the provisions of 18 U.S.C. § 3161(h)(6) and the ends of justice outweighed the best interest of the public and the defendant in a speedy trial under 18 U.S.C. § 3161(h)(7). The court excluded the time from October 24, 2007 to the commencement of the trial, not yet scheduled, for purposes of the Speedy Trial Act.
On December 11, 2007, Toombs filed a motion to dismiss alleging a violation of his Sixth Amendment right to a speedy trial. The district court denied this motion. On February 26, 2008, Toombs filed another motion to dismiss. In this motion, Toombs alleged the district court erroneously excluded the time periods identified in the seven ends-of-justice continuances because it did not make the factual findings required by the ends-of-justice provision of the Speedy Trial Act. Toombs argued that over seventy non-exeludable days had passed between the time of his arraignment and the start of the trial in violation of the Speedy Trial Act, 18 U.S.C. § 3161(c)(1).
At the hearing on the motion, the district court clarified its findings as to the continuances granted on September 5, 2006 and August 28, 2007. The district court explained that at the time those continuances were granted, this court had not issued its decision in United States v. Williams, 511 F.3d 1044 (10th Cir.2007). The district court acknowledged that, in light of Williams, its findings for those two continuances were not sufficient. To remedy the perceived deficiencies, the district court stated that in granting the motions it considered defense counsel’s statements that additional time was needed to review discovery in order to effectively prepare [1268]*1268for trial and weighed this against the interests of Toombs and the public in a speedy trial. The district court explained that while adding such findings to the record so long after granting the continuances was not the preferred practice, it was nonetheless appropriate because the court had made the findings when it initially granted the motions. The district court then concluded Toombs’s rights under the Speedy Trial Act had not been violated because for each continuance it had properly balanced the appropriate considerations and included its findings in the record. The district court therefore denied the motion to dismiss.
Toombs’s trial began on March 4, 2008. The jury returned a guilty verdict on all counts and the district court sentenced Toombs to thirty-five years’ imprisonment. On appeal, Toombs claims, inter alia? that the district erred in denying his motions to dismiss for violations of the Speedy Trial Act and the Sixth Amendment right to a speedy trial.
III. DISCUSSION
A. The Speedy Trial Act
“We apply an abuse of discretion standard to a district court’s decision to grant an ends-of-justice continuance.... ” United States v. Gonzales, 137 F.3d 1431, 1433 (10th Cir.1998). This court reviews de novo, however, the district court’s compliance with the legal requirements of the Speedy Trial Act. United States v. Thompson, 524 F.3d 1126, 1131 (10th Cir.2008). The district court’s factual findings are reviewed for clear error. Id. “The Speedy Trial Act is designed to protect a criminal defendant’s constitutional right to a speedy trial and serve the public interest in bringing prompt criminal proceedings.” Id. It requires that a criminal trial commence within seventy days of the filing of the indictment or information or the defendant’s appearance, whichever occurs last.4
5 18 U.S.C. § 3161(c)(1). Excluded from the seventy-day requirement is:
Any period of delay resulting from a continuance granted by any judge on his own motion or at the request of the defendant or his counsel or at the request of the attorney for the Government, if the judge granted such continuance on the basis of his findings that the ends of justice served by taking such action outweigh the best interest of the public and the defendant in a speedy trial.
Id. § 3161(h)(7)(A).
In order to exclude this time pursuant to the ends-of-justice provision, however, the Speedy Trial Act requires that “the court sets forth, in the record of the case, either orally or in writing, its reasons for finding that the ends of justice served by the granting of such continuance outweigh the best interests of the public and the defendant in a speedy trial.” Id. In doing so, the judge must consider:
(i) Whether the failure to grant such a continuance in the proceeding would be likely to make a continuation of such proceeding impossible, or result in a miscarriage of justice.
(ii) Whether the case is so unusual or so complex, due to the number of defendants, the nature of the prosecution, or the existence of novel questions of fact or law, that it is unreasonable to expect [1269]*1269adequate preparation for pretrial proceedings or for the trial itself within the time limits established by this section.
(iii) Whether, in a case in which arrest precedes indictment, delay in the filing of the indictment is caused because the arrest occurs at a time such that it is unreasonable to expect return and filing of the indictment within the period specified in section 3161(b), or because the facts upon which the grand jury must base its determination are unusual or complex.
(iv) Whether the failure to grant such a continuance in a case which, taken as a whole, is not so unusual or so complex as to fall within clause (ii), would deny the defendant reasonable time to obtain counsel, would unreasonably deny the defendant or the Government continuity of counsel, or would deny counsel for the defendant or the attorney for the Government the reasonable time necessary for effective preparation, taking into account the exercise of due diligence.
Id. § 3161(h)(7)(B)(i)-(iv).
“Th[e] [ends-of-justice] exception to the otherwise precise requirements of the Act was meant to be a rarely used tool for those cases demanding more flexible treatment.” United States v. Doran, 882 F.2d 1511, 1515 (10th Cir.1989) (quotation omitted). The requirement that the district court make clear on the record its reasons for granting an ends-of-justice continuance serves two core purposes. Id. It both ensures the district court considers the relevant factors and provides this court with an adequate record to review. Id. “Failure to address [the reasons] on the record creates the unnecessary risk of granting continuances for the wrong purposes, and encourages overuse of this narrow exception.” Id. Thus, “the record must clearly establish the district court considered the proper factors at the time such a continuance was granted.” Gonzales, 137 F.3d at 1433. “In setting forth its findings, however, the district court need not articulate facts which are obvious and set forth in the motion for the continuance itself.” United States v. Occhipinti, 998 F.2d 791, 797 (10th Cir.1993) (quotation omitted). While the preferred practice is for the district court to make its findings on the record at the time the continuance is granted, findings made contemporaneously with the granting of the continuance may be entered on the record after the fact if done before the court rules on a defendant’s motion to dismiss. Zedner v. United States, 547 U.S. 489, 506-07 & n. 7, 126 S.Ct. 1976, 164 L.Ed.2d 749 (2006).
Toombs claims the district court made insufficient findings as to the seven continuances expressly granted pursuant to the ends-of-justice provision. Fifty days in the approximately twenty-two month period between Toombs’s arraignment and trial date were not excluded by the district court for Speedy Trial Act purposes.6 Because pursuant to each of the seven challenged continuances the district court excluded over twenty days, if any one of the continuances was granted in error, a violation of the seventy-day requirement of the Speedy Trial Act would exist. 18 U.S.C. § 3161(c)(1).
The record is particularly sparse with regard to the district court’s findings underlying two of the ends-of-justice continuances. The May 1, 2007, order states in relevant part:
The Court, having been well and duly advised in the premises, finds that the motion should be granted in order for [1270]*1270the defense to adequately prepare and for the reasons stated in the motion.
The Court further finds that the period of delay resulting from the continuance granted pursuant to this order shall be excludable time as provided for in 18 U.S.C. [§ 3161(h)(7) ] in that the ends of justice served by the granting of such continuance outweigh the best interest of the public and the defendant in a speedy trial.
The motion to which this order refers, filed on April 30, 2007, states that a continuance is requested on the following grounds:
1. This case is scheduled for Jury Trial commencing May 7, 2007 at 1:30 p.m.
2. That additional discovery has recently been disclosed to Defendant requiring additional investigation.
3. The Assistant United States Attorney has advised that she has no objection to this request.
4. This application for continuance is made in good faith on the grounds stated and not to vex or harass the Court or the United States of America.
5. The ends of justice will be served by taking such action which outweighs the best interest of the public and the defendant in a speedy trial pursuant to [18 U.S.C. § 3161(h)(7)(A) ].
The motion to continue filed July 5, 2007, is in all material respects identical to the April 30, 2007, motion. Similarly, with the exception of the dates provided, the district court’s July 10, 2007, order granting the July 5, 2007, motion to continue is identical to its May 1, 2007, order granting the April 30, 2007, motion to continue.
In Gonzales, this court considered whether a district court made sufficient findings under the Speedy Trial Act when it granted an ends-of-justice continuance to the prosecution. 137 F.3d at 1434-35. In the hearing to set a trial date, the district court suggested two dates, August 5 and August 19. Id. at 1434. The prosecutor claimed neither would work because he was going to be out of town on the days preceding each of the dates, rendering it difficult for him to prepare for trial. Id. The court suggested a third option, August 26, to which the prosecutor agreed, but to which the defense objected on Speedy Trial Act grounds. Id. After briefly questioning the prosecutor about why he would be out of town for the week preceding August 19, the court again suggested August 5. Id. The prosecutor stated he had three witnesses scheduled to leave town during the weeks preceding August 5 and he did not know when they would return. Id. Thus, he contended it would be extremely difficult to have the trial on that date. Id. Based upon this information, the court set the trial date for August 26 and granted an ends-of-justice continuance excluding the relevant time period. Id. The written order stated in relevant part that the time was excluded for purposes of the Speedy Trial Act because the interests of justice outweighed the interest of the public and the defendant in a speedy trial “based upon the finding that [government] counsel ... would be denied the reasonable and necessary time to prepare for trial, taking into account due diligence, and risks which cause a potential miscarriage of justice and risk the continuity of [government] counsel.” Id.
This court considered both the statements made by the prosecutor and district court during the hearing and the content of the later written order, and concluded the district court failed to create an adequate record of its reasons for granting the continuance. Id. at 1434-35. This court noted a number of problems. Id. First, the district court had not inquired into the nature or complexity of the case at issue as required by § 3161(h)(7)(B)(ii) and (iv). Id. at 1434. In addition, there was no inquiry as to whether continuity of [1271]*1271counsel was necessary or whether the case could be tried by other government counsel. Id. at 1434-35 (citing § 3161(h)(7)(B)(iv)). There was also no inquiry concerning the reason the prosecutor would be out of town during the week preceding the proposed August 5 trial date, whether counsel’s trip could be rescheduled, or when the witnesses would return. Id. at 1435. Finally, there was no mention of how much time the prosecutor actually needed to prepare for trial or what preparations he had already made. Id. The court concluded that:
Without this information, we fail to see how the district court adequately could have determined whether denial of a continuance would have deprived the prosecutor of “reasonable time necessary for effective preparation,” 18 U.S.C. § [3161(h)(7)(B)(iv) ], let alone whether the purported reasons for granting the continuance outweighed the best interests of the public and Gonzales in a speedy trial.
Id. (emphasis added).
This court also considered a district court’s grant of an ends-of-justice continuance in Williams, 511 F.3d at 1055-59. The defendant in Williams requested a continuance on the grounds his new attorney needed additional time to become familiar with the case. Id. at 1057. The district court noted the presence of new counsel and granted the motion to continue, excluding the relevant time period for purposes of the Speedy Trial Act. Id. This court first acknowledged the district court need not articulate facts that are obvious and set forth in the motion to continue in granting an ends-of-justice continuance. Id. It nonetheless concluded the district court’s findings were insufficient for purposes of the Speedy Trial Act, stating:
Although the district court in this case mentioned the presence of new counsel in its November 22 order, it did not issue findings specifically addressing Mr. Williams’s stated grounds for a continuance, i.e., his new counsel’s claimed need for time to familiarize himself with the case. Nor did the district court otherwise comment on the issue of trial preparation time. Furthermore, the court’s order does not so much as hint that it weighed the proper factors under the Act. Indeed, the court failed to cite the Act’s ends-of-justice provision. Thus, we conclude that the district court did not properly exclude [the relevant periods] under the Act.
Id. at 1058.
Our decisions in Williams and Gonzales indicate that the record, which includes the oral and written statements of both the district court and the moving party, must contain an explanation of why the mere occurrence of the event identified by the party as necessitating the continuance results in the need for additional time.7 Williams, 511 F.3d at 1058; Gonzales, 137 F.3d at 1434-35. A record consisting of only short, conclusory statements lacking in detail is insufficient. For example, it is insufficient to merely state that counsel is new and thus needs more time to adequately prepare for trial or that counsel or witnesses will be out of town in the weeks preceding trial and therefore more time is needed to prepare for trial. Williams, 511 F.3d at 1058; Gonzales, 137 F.3d at 1434-35. Simply identifying an event, and adding the conclusory state[1272]*1272ment that the event requires more time for counsel to prepare, is not enough. Williams, 511 F.3d at 1058; Gonzales, 137 F.3d at 1434-35.
Under this standard, the reasoning contained in the record for the May and July 2007 ends-of-justice continuances is inadequate. The sole explanation contained in the record for each of the continuances is that discovery was recently disclosed and counsel consequently needed additional time to prepare for trial. The district court here, much like the district courts in Williams and Gonzales, failed to inquire about or consider whether the respective events at issue necessarily required additional preparation. There is no indication from either Toombs’s motions or the district court’s orders as to the nature of the recently disclosed discovery, the relevance or importance of the discovery, or why the district court thought it proper to grant an approximately two-month continuance in each of the orders. Instead, the court twice erroneously relied upon conclusory statements lacking both detail and support in granting the continuances.
The case relied upon by the government on appeal and the district court in denying Toombs’s motion to dismiss, Occhipinti 998 F.2d 791, is factually distinguishable from the instant case. In Occhipinti the government sought a continuance on the grounds that it needed more time to prepare for trial. Id. at 797. In its motion to continue, the government explained that it expected the defendant’s trial to last for ten to fifteen days and that over the next two months counsel was scheduled for three conflicting trials. Id. The motion provided the dates of those trials and the length of time the government expected each trial to last. Id. The motion further stated that because of the conflicting trials, the government would not have adequate time to prepare for the trial at issue. Id. In its order, the district court concluded a continuance was necessary to give the government time to prepare and excluded the time pursuant to the ends-of-justice provision of the Speedy Trial Act. Id. This court concluded that the record was sufficient, although a “more thorough and explicit articulation might have better facilitated our review of the district court’s decision.” Id. at 798.
Based upon our holdings in Gonzales and Williams, it is safe to say that in Occhipinti the district court made the minimal findings necessary for this court to conclude the record was sufficient under the ends-of-justice provision of the Speedy Trial Act. See Williams, 511 F.3d at 1058 (noting that this court “did not even find Occhipinti’s [findings] to be optimally thorough and explicit” (quotation omitted)); Gonzales, 137 F.3d at 1434-35. In Occhipinti the government’s listing of the dates for each of the three other trials and their expected durations provided an explanation, although not optimally detailed, of why these events, the trials, would require additional time for the government to prepare for the upcoming trial, which it expected to last for ten to fifteen days. Here, unlike in Occhipinti there is absolutely no explanation in the record for why the events, receiving newly disclosed discovery, resulted in defense counsel requiring additional time to prepare for trial. There was no discussion whatsoever in the May and July 2007 motions and orders regarding the nature or importance of the disclosed discovery or the nature of the further investigation allegedly required and no hearings took place. Thus, the record does not satisfy even the minimal threshold set forth in Occhipinti.
Were the Speedy Trial Act to be applied as proposed by the dissent, this court’s precedent and the words of Congress would be eviscerated. According to the dissent, all that is required for the grant[1273]*1273ing of an ends-of-justice continuance is what occurred in this case: a motion containing only conclusory statements indicating as generally as possible in two one-sentence paragraphs that the disclosure of new evidence requires additional investigation and the ends of justice would be served by a continuance. As in this case, there is no need for a hearing. Nor is there a need to inquire as to the nature, extent, or quantity of the new evidence.8 Finally, there is no need to inquire even as to the amount of time needed.
The dissent presents no authority for the ease with which it proposes to authorize continuances under the Speedy Trial Act. The approach advanced by the dissent would encourage greater reliance on the narrow ends-of-justice provision, contrary to precedent. Doran, 882 F.2d at 1515 (“This exception to the otherwise precise requirements of the Act was meant to be a rarely used tool for those cases demanding more flexible treatment.” (quotation omitted)). This case is illustrative. Nine trial continuances were granted over the twenty-months from arraignment to trial, seven of which were premised on the ends-of-justice provision.9
While the dissent attributes some significance to the fact that “most of the delays in this case [were] attributable to the defendant,” Dissenting Op. at 1277, defense responsibility for continuances does not unwind Speedy Trial Act violations. The Speedy Trial Act was intended not only to protect the interests of defendants, but was also “designed with the public interest firmly in mind.” Zedner, 547 U.S. at 501, 126 S.Ct. 1976. The ends-of-justice provision expressly mandates that the district court articulate “its reasons for finding that the ends of justice served by the granting of such continuance outweigh the best interests of the public and the defendant in a speedy trial.” 18 U.S.C. § 3161(h)(7)(A) (emphasis added). It is the responsibility of not only the district court, but also the government, to protect the interests of the public by ensuring adherence to the requirements of the Speedy Trial Act. See United States v. Wright, 6 F.3d 811, 814 (D.C.Cir.1993) (“[T]he Government bears a large part of the responsibility for bringing a defendant to trial within the statutory period.... ”). Thus, the district court and government are no less responsible under the Speedy Trial Act merely because it is a defendant who requests a continuance. See Zedner, 547 U.S. at 493-95, 507, 126 S.Ct. 1976 (concluding a violation of the Speedy Trial Act occurred when the district court failed to make adequate factual findings in granting an ends-of-justice continuance requested by the defendant). The government was passive, it never objected to any of the continuances or so much as inquired before the court into their necessity. By failing to make a record upon which adequate findings could be based, the district court failed to protect the public’s interest [1274]*1274in a speedy trial as required by the Speedy Trial Act and the clear application of that Act necessitates reversal of the district court’s denial of the motion to dismiss.
B. The Sixth Amendment Right to a Speedy Trial
Because a district court has discretion to dismiss the case with or without prejudice upon a Speedy Trial Act violation, we also consider Toombs’s Sixth Amendment speedy trial claim, which, if successful, would require the district court to dismiss the case with prejudice. See Barker v. Wingo, 407 U.S. 514, 522, 92 S.Ct. 2182, 33 L.Ed.2d 101 (1972) (“The amorphous quality of the [Sixth Amendment speedy trial] right also leads to the unsatisfactorily severe remedy of dismissal of the indictment when the right has been deprived. This is indeed a serious consequence because it means that a defendant who may be guilty of a serious crime will go free, without having been tried.”).
“The Sixth Amendment guarantees all criminal defendants the right to a speedy trial.... ” United States v. Yehling, 456 F.3d 1236, 1243 (10th Cir.2006). In determining whether a defendant’s Sixth Amendment right to a speedy trial has been violated, a court must balance four factors: (1) the length of delay; (2) the reason for delay; (3) the defendant’s assertion of his right; and (4) any prejudice to the defendant. Barker, 407 U.S. at 530, 92 S.Ct. 2182. No one of the factors is necessary or sufficient to conclude a violation has occurred. Id. Instead, the factors are related and must be considered together along with other relevant circumstances. United States v. Gomez, 67 F.3d 1515, 1521 (10th Cir.1995). “The first factor, length of delay, functions as a triggering mechanism” and “the remaining factors are examined only if the delay is long enough to be presumptively prejudicial.” Yehling, 456 F.3d at 1243 (quotation omitted).
The parties agree that the length of delay is presumptively prejudicial, requiring this court to consider the other three factors in the analysis. As to the second factor, reason for the delay, seven of the nine continuances granted by the district court in this case were requested by Toombs. In addition, as the district court noted and the government points out, of the 671 days between the filing of Toombs’s indictment and the start of his trial, 423 were attributable to motions filed by Toombs. Delays attributable to the defendant do not weigh in favor of a Sixth Amendment violation. United States v. Dirden, 38 F.3d 1131, 1138 (10th Cir.1994). Because Toombs’s actions were the primary cause of the delay, this factor weighs heavily against Toombs. See United States v. Abdush-Shakur, 465 F.3d 458, 465 (10th Cir.2006) (“We find little merit in defendant’s assertion of his Sixth Amendment right to a speedy trial in the wake of the government’s legitimate request for a continuance when the defendant has sat on his hands for seven months and requested several continuances of his own.”).
As to the third factor, this court has stated that “the defendant’s assertion of the speedy trial right is entitled to strong evidentiary weight in determining whether the defendant is being deprived of the right.” Dirden, 38 F.3d at 1138 (quotation omitted). Toombs did not assert his Sixth Amendment right to a speedy trial until his October 29, 2007, motion to sever. By the time Toombs asserted his Sixth Amendment right, eight of the nine continuances, seven of which were requested by him, had already been granted and approximately seventeen months had passed since his first court appearance. Thus, this factor also weighs heavily against Toombs. See United States v. Batie, 433 [1275]*1275F.3d 1287, 1292 (10th Cir.2006) (“[Defendant’s] persistent requests for continuances ... scarcely demonstrate a desire for a speedier process.”).
Finally, the fourth factor considers prejudice to the defendant resulting from the delay. Yehling, 456 F.3d at 1244. In Doggett v. United States, the Supreme Court held that if there is extreme delay, the defendant need not present specific evidence of prejudice and instead may rely on the presumption of prejudice created by the extreme delay. 505 U.S. 647, 655, 112 S.Ct. 2686, 120 L.Ed.2d 520 (1992). The Doggett Court concluded extreme delay existed when over eight years, six of which were attributable to the government, had passed between the defendant’s indictment and trial. Id. at 657-58, 112 S.Ct. 2686. The twenty-two month delay here, however, the vast majority of which was attributable to the defense, is far shorter than the delay in Doggett and does not constitute extreme delay. See United States v. Serna-Villarreal, 352 F.3d 225, 232 (5th Cir.2003) (“Indeed, this Court and others generally have found presumed prejudice only in cases in which the post-indictment delay lasted at least five years.”). Thus, in determining whether Toombs has made a particularized showing of prejudice this court is to consider the three interests the speedy trial right was designed to protect: (1) prevention of oppressive pretrial incarceration, (2) minimization of the accused’s anxiety and concern, and (3) minimization of the possibility that a delay will hinder the defense. Barker, 407 U.S. at 532, 92 S.Ct. 2182. The most important of these interests is the impairment or hindrance of the defense. Id. The individual claiming the Sixth Amendment violation has the burden of showing prejudice. Yehling, 456 F.3d at 1245. Furthermore, “once a defendant has been convicted, the rights of society increase in proportion to the rights of the defendant. Post-conviction prejudice therefore must be substantial and demonstrable.” Id. (quotation and citation omitted).
Even assuming the first two interests, prevention of oppressive pretrial incarceration and minimization of the accused’s anxiety and concern, weigh in Toombs’s favor, the third, and most important, does not. Toombs argues that the delay hindered his defense because during the relevant time period the government was able to locate and procure the testimony of his co-defendant and the primary witness against him, Arlynda Osborn, rendering the government’s case much stronger. Toombs does not, however, claim his defense was hindered in the sense that he was not able to defend the charges against him to the extent he desired. This is not a situation where, for example, as a result of the delay, the defense no longer had access to certain evidence or could no longer use a witness because that witness died before trial. See Jackson v. Ray, 390 F.3d 1254, 1264 (10th Cir.2004). Thus, Toombs’s defense has not been hindered in the sense envisioned by the Barker analysis. See Castro v. Ward, 138 F.3d 810, 820 (10th Cir.1998) (concluding no prejudice existed where “despite [petitioner’s] general allegation that the passage of time made it more difficult for him to present a defense[,] ... [h]e has not claimed that any specific witness or evidence was somehow rendered unavailable or less persuasive because of the passage of time”).
In addition, Toombs’s multiple requests for continuances contributed significantly to the government’s ability to locate and arrest Osborn. Three continuances, all requested by Toombs, were granted before the government sought additional time to locate Osborn. Moreover, an additional four continuances requested by Toombs were granted between the government’s first motion to continue in order to locate Osborn and the government’s second mo[1276]*1276tion to continue upon arresting Osborn. Toombs’s motions to continue therefore provided the government with the time it needed to locate and arrest Osborn. Since the hindrance to the defense is the most important interest, and the defense was not significantly hindered here, the prejudice factor does not weigh in favor of Toombs. See Batie, 433 F.3d at 1293 (“Absent extraordinary circumstances, Barker counsels us not to find a violation of the right to a speedy trial when the defendant’s actions indicate he had no desire for a speedy trial.”).
Although the delay here was presumptively prejudicial, the second and third factors in the Barker analysis weigh heavily against Toombs, and the fourth does not weigh in his favor. In balancing the factors, it is clear Toombs has not made out a Sixth Amendment speedy trial violation. We therefore affirm the district court’s denial of the motion to dismiss on Sixth Amendment speedy trial grounds.
IV. CONCLUSION
For the reasons discussed above, we affirm the district court’s denial of the motion to dismiss on Sixth Amendment speedy trial grounds, reverse the denial of the motion to dismiss on Speedy Trial Act grounds, and remand for proceedings consistent with this opinion. On remand, the district must decide whether to dismiss the indictment with or without prejudice. Williams, 511 F.3d at 1049 (“The sanction for violation of the Act is mandatory dismissal of the indictment. 18 U.S.C. § 3162(a)(2). However, the district court retains broad discretion whether to dismiss the indictment with or without prejudice.” (quotations omitted)).
