PER CURIAM.
Isaac Roubideaux was convicted of eight separate offenses involving firearms
and failure to register as a sex offender, and the district court originally sentenced
him to 513 months’ imprisonment. In his previous appeal, United States v.
Roubideaux, No. 22-2911, 2023 WL 8665006 (8th Cir. Dec. 15, 2023), we affirmed
his convictions but vacated his sentence based on procedural errors. On remand, the

district court1 sentenced Roubideaux to a total term of imprisonment of 360 months.
Roubideaux appeals, asserting that his sentence is substantively unreasonable.
Having jurisdiction under 28 U.S.C. § 1291, we affirm.
Following a shooting during a drug transaction that left the victim paralyzed
from the waist down, Roubideaux was charged with eight separate counts: (1)
discharge and brandishing of a firearm during a crime of violence, in violation of 18
U.S.C. § 924(c)(1)(A)(iii); (2) assault with a dangerous weapon, in violation of 18
U.S.C. §§ 113(a)(3) and 1153; (3) assault resulting in serious bodily injury, in
violation of 18 U.S.C. §§ 113(a)(6) and 1153; (4) failure to register as a sex offender,
in violation of 18 U.S.C. §§ 2250(a) and 2250(d)(1); (5) failure to register as a sex
offender, in violation of 18 U.S.C. § 2250(a); (6) another count of failure to register
as a sex offender, in violation of 18 U.S.C. § 2250(a); (7) possession of a firearm by
a felon, in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2); and (8) possession of
a firearm by a drug user, in violation of 18 U.S.C. §§ 922(g)(3) and 924(a)(2). A
jury convicted Roubideaux of all eight counts, after which the district court
sentenced Roubideaux to what it stated was a total of 442 months’ imprisonment.
However, the judgment reflected that the actual sentence imposed was 513 months’
imprisonment, consisting of 120 months for Count 1; 71 months for Count 2; 120
months for Count 3; 60 months for Count 4; and 71 months for Count 7, running
consecutively to each other and all other counts, with an additional 60 months for
Count 5; 60 months for Count 6; and 71 months for Count 8 running concurrently to
each other.
Roubideaux appealed his convictions and sentence, and this Court held that
the district court committed procedural error because, in imposing the sentence for
Count 4, the district court erroneously stated that the sentence must run
consecutively to all other counts, rather than correctly acknowledging that it must
run consecutively to only Count 5. Further, the district court erroneously used the

60-month mandatory minimum for Count 4 to raise the floor of the Guidelines range
for grouped Counts 2, 3, 5, 6, 7, and 8, for which the appropriate bottom of the
Guidelines range would have been 57 months. We also noted that the district court
stated it was imposing an upward variance of 49 months with respect to Count 3 but
observed that Roubideaux’s total sentence reflected a 191-month upward variance;
we tasked the district court with considering on remand whether it intended to
impose a variance of this magnitude. Finally, we noted that the judgment did not
provide a total sentence, and that the stated sentence of 442 months appeared to have
been based on a miscalculation of all the individual sentences. We affirmed
Roubideaux’s convictions but vacated Roubideaux’s sentence and ordered
re-sentencing.
On remand, the district court sentenced Roubideaux to a total term of
imprisonment of 360 months, consisting of 120 months for Count 1; 120 months for
Count 3; 60 months for Count 4; and 60 months for Count 5, with those sentences
running consecutively, and 71 months for Count 2; 60 months for Count 6; 71
months for Count 7; and 71 months for Count 8, with those sentences running
concurrently with Count 3. In imposing this sentence, the district court varied
upward on Count 3 from a 57-71 month range to 120 months based on the
seriousness of the offense—assault resulting in serious bodily injury—which left the
victim paralyzed. The district court also stated that, with respect to the overall
sentence, “there needs to be a further upward variance because . . . this is not the
ordinary heartland case,” as it involved “one of the most serious bodily injuries
resulting from an assault” that the district court had ever seen and that Roubideaux
committed the offense as an unregistered sex offender. It thus decided that a 360-
month term of imprisonment was sufficient, which it achieved by ordering Counts
1, 3, 4, and 5 to run consecutively, acknowledging that this was a 169-month upward
variance from the top of the Guidelines range if it had ordered all the sentences that
could be run concurrently to do so.
Roubideaux now challenges the substantive reasonableness of his sentence,
asserting that the district court erred when it imposed a further upward variance, but

-- 3 of 5 --

conceding that the 49-month upward variance on Count 3 was appropriate. “We
review the substantive reasonableness of a sentence ‘under a highly deferential
abuse-of-discretion standard.’” United States v. Madrigal, 136 F.4th 766, 777 (8th
Cir. 2025) (citation omitted). “A court abuses its discretion if it fails to consider a
relevant factor that should have received significant weight; gives significant weight
to an improper or irrelevant factor; or considers only the appropriate factors but in
weighing those factors commits a clear error of judgment.” United States v. Cain,
976 F.3d 778, 780 (8th Cir. 2020) (per curiam) (citation omitted).
Roubideaux asserts that the district court abused its discretion by varying
upward to extend his total sentence because each of the justifications the district
court relied on to support the variance were already factored into the sentence as
Count 1 and Count 4 required mandatory consecutive punishments. We disagree.
“When the district court imposes a sentence outside the Guidelines range, . . . [we]
‘may consider the extent of the deviation, but must give due deference to the district
court’s decision that the § 3553(a) factors, on a whole, justify the extent of the
variance.’” United States v. Luscombe, 950 F.3d 1021, 1031-32 (8th Cir. 2020)
(alterations in original) (citation omitted). The district court provided a detailed
explanation of why the facts in this case warranted an upward variance, including
that Roubideaux shot his own cousin in the back as he was walking away, that
Roubideaux left him to die in the street, that the victim was paralyzed due to the
shooting, and that Roubideaux committed this offense while he was an unregistered
sex offender. This was an appropriate consideration of the relevant sentencing
factors, regardless of whether the Guidelines range also considered this conduct. See
United States v. Parker, 112 F.4th 621, 623 (8th Cir. 2024) (per curiam) (“While
courts must use caution when supporting a substantial upward variance with factors
already reflected in the Guidelines, ‘[f]actors that have already been taken into
account in calculating the advisory Guidelines range can nevertheless form the basis
of a variance.’” (alteration in original) (citation omitted)). Further, “[u]nder [18
U.S.C. § 3584], a district court has the discretion to impose a sentence concurrently
or consecutively based on the same § 3553(a) factors as other sentencing decisions.”
United States v. Boyum, 54 F.4th 1012, 1016 (8th Cir. 2022) (second alteration in

original) (citation omitted). We are satisfied that the district court’s decision to vary
upward beyond the variance in the sentence for Count 3 “rest[s] on precisely the
kind of defendant-specific determinations that are within the special competence of
sentencing courts, as the Supreme Court has repeatedly emphasized.” United States
v. Feemster, 572 F.3d 455, 464 (8th Cir. 2009) (en banc) (citation omitted). The
district court thus did not abuse its discretion and did not impose a substantively
unreasonable sentence.
Accordingly, we affirm.
