United States v. Christopher Douglas, 910 F.3d 804

Christopher Douglas pled guilty to kidnapping (E.D. Tex., transferred to W.D. La.) and federal drug charges (W.D. La.); separate PSRs prepared for each count.
PSR ranges: kidnapping 262–327 months; drug 188–235 months. District court sentenced 324 months (kidnapping) and 192 months (drug), ordering 96 months concurrent and 96 months consecutive, producing a 420-month aggregate sentence. Neither party objected below.
The district court marked the sentences as within the Guidelines on its statements of reasons.
On appeal the Fifth Circuit sua sponte raised whether the district court erred by failing to determine a combined offense level under U.S.S.G. §§ 3D1.1–.4 and 5G1.2, ordered supplemental briefing, and the parties agreed there was error.
Fifth Circuit concluded the counts do not group together (different harms), so the drug group (offense level 26) is 10 levels lower than the kidnapping group (36) and is therefore disregarded under § 3D1.4, producing a combined offense level of 36 reduced for acceptance and career-offender rules to a combined level of 34 and a Guidelines range of 262–327 months.
Because the district court imposed a 420-month aggregate sentence without stating an upward departure, the Fifth Circuit found plain error, vacated the sentence, and remanded for resentencing.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the district court erred by failing to apply the Chapter 3 grouping rules (§§ 3D1.1–3D1.4) and thus miscalculating a combined offense level and Guidelines range	Douglas argued only substantive unreasonableness on appeal, but parties agreed district court erred by not grouping and failing to compute a combined offense level	Government agreed district court erred and (originally) offered a different combined-range calculation, later adopting the correct approach after briefing	Court held the court plainly erred: counts are separate groups, drug group is ≥9 levels lower and disregarded under § 3D1.4, yielding a combined Guidelines range of 262–327 months; sentence vacated and remanded.
Whether appellate court may correct an unpreserved sentencing-range error (plain-error review)	Douglas did not preserve the grouping error below or raise it in opening brief	Government did not oppose appellate plain-error review and conceded the error after court's inquiry	Court exercised discretion to review for plain error under Rule 52(b) and precedent (Silber/Atkinson/Delgado) and found plain error affecting fairness and integrity (citing Rosales-Mireles), warranting vacatur and resentencing.
