MEMORANDUM AND ORDER

Before the Court are defendant Angel Omar Almonte’s motions to dismiss the indictment for violations of the Speedy Trial Act (“STA”) and the Sixth Amendment of the U.S. Constitution and for an order of release (Docket Nos. 31 & 47), and the United States’s responses (Docket Nos. 37, 55, & 56). For the reasons that follow, the Court DENIES defendant’s motions.

I. Defendant’s Motion to Dismiss the Indictment

Defendant argues for the dismissal of the indictment due to violations of the STA and the Sixth Amendment. The Court *344addresses each proffered ground for dismissal in turn.

A. Speedy Trial Act

The STA requires that trial commence within seventy days of the filing of an indictment, or the first appearance of the defendant in court, whichever is later. 18 U.S.C. § 3161(c)(1). Certain periods of delay, as outlined in section 3161(h)(l)-(9), are excluded from the seventy-day calculation. Id. § 3161(h). These exclusions include delays “resulting from any pretrial motion, from the filing of the motion through the conclusion of the hearing on, or other prompt disposition of, such motion.” Id. § 3161(h)(1)(D); see also Bloate v. United States, 559 U.S. 196, 205, 130 S.Ct. 1345, 176 L.Ed.2d 54 (2010). If trial does not commence by the end of seventy days plus the excluded periods, the “indictment shall be dismissed on motion of the defendant.” Id. § 3162(a)(2).

Almonte contends that the indictment should be dismissed because more than seventy non-excludable days have elapsed since the time of his first appearance before a judicial officer on September 4, 2013.1 Almonte offers five excludable days. After initially conceding the existence of an STA violation (Docket No. 37), the government correctly amended its position and now contends that the STA clock did not begin to run at the time of his arraignment. (Docket No. 56.) Rather, the clock began to run upon the arraignment of the last co-defendant, Jose Nicomedes Ramirez-Jejeda, on December 16, 2013. See United States v. Casas, 425 F.3d 23, 31 (1st Cir. 2005) (“The Supreme Court has interpreted this section to mean that the clock does not, in effect, begin to run until the date of the most recent defendant’s initial appearance before the court.”) (citing 18 U.S.C. § 3161(h)(6) and Henderson v. United States, 476 U.S. 321, 323 n. 2, 106 S.Ct. 1871, 90 L.Ed.2d 299 (1986)).2 The STA clock has been tolled since Almonte filed the motion to dismiss on December 3, 2013. See 18 U.S.C. § 3161(h)(1)(D). Accordingly, because no STA days have elapsed, Almonte’s motion to dismiss for violation of the Speedy Trial Act is DENIED.

B. Sixth Amendment

Almonte also moves for dismissal of the indictment on Sixth Amendment grounds. “Although unusual, it is possible for a delay that does not violate the STA to run afoul of the Sixth Amendment’s guarantee of a speedy trial.” Casas, 425 F.3d at 33 (citing United States v. Salimonu, 182 F.3d 63, 69 (1st Cir. 1999) and 18 U.S.C. § 3173.). In determining whether a defendant’s Sixth Amendment right to a speedy trial has been violated, courts consider four factors: (1) the length of the delay; (2) the reasons for the delay; (3) the defendant’s assertion of his or her speedy trial right; and (4) prejudice to the defendant caused by the delay. See Barker v. Wingo, 407 U.S. 514, 530, 92 S.Ct. 2182, 33 L.Ed.2d 101 (1972). None of the factors is “either a necessary or sufficient condition to the finding of a deprivation of the right of speedy trial. Rather, they are related factors and must be considered together with such other circumstances as may be relevant.” Id. at 533, 92 S.Ct. 2182.

The length of pretrial delay is calculated from arrest or indictment, whichever occurs first. United States v. *345Muñoz-Amado, 182 F.3d 57, 61 (1st Cir. 1999). Here, Almonte was arrested on September 4, 2013, less than the one-year point at which pretrial delay is generally considered presumptively prejudicial and triggers further inquiry. See Doggett v. United States, 505 U.S. 647, 652 n. 1, 112 S.Ct. 2686, 120 L.Ed.2d 520 (1992) (inter“nal citations omitted). Thus, the length of delay fails to trigger further inquiry pursuant to Barker. Nevertheless, the Court does not find that the remaining three Barker factors weigh in favor of a finding that Almonte’s Sixth Amendment right to a speedy trial was violated. Accordingly, Almonte’s motion to dismiss on Sixth Amendment grounds is DENIED. Almonte’s request for an order of release is also DENIED.

II. Request for New Bail Hearing

Should his motion to dismiss be denied, Almonte in the alternative requests a de novo bail hearing, but does not provide any argument or support for such a request. Given the absence of any support for granting his request, Almonte’s request for a de novo bail hearing is DENIED. See United States v. Zannino, 895 F.2d 1, 17 (1st Cir. 1990) (“It is not enough merely to mention a possible argument in the most skeletal way, leaving the court to do counsel’s work, create the ossature for the argument, and put flesh on its bones.”)

III. Conclusion

For the reasons articulated above, Almonte’s motion to dismiss the indictment for violations of the Speedy Trial Act and the Sixth Amendment, his motion seeking an order of release, and his request for a de novo bail hearing are DENIED.

IT IS SO ORDERED.
