United States v. Flores-Nater, 62 F.4th 652

Flores‑Nater and four gang members kidnapped WGE from public housing; all carried assault rifles; Flores‑Nater shot WGE in the head and the victim died.
Arrested in 2020; indicted on kidnapping resulting in death and multiple firearm counts; pleaded guilty to discharging a firearm in furtherance of a crime of violence, 18 U.S.C. § 924(c)(1)(A)(iii).
PSI calculated the guideline sentence at 120 months (mandatory minimum). No objections to the PSI.
Plea agreement: government to dismiss other counts; parties jointly recommended a 25‑year sentence (a 15‑year upward variance from the guideline).
District court recited facts, stated it had considered 18 U.S.C. § 3553(a) factors, rejected the parties’ joint recommendation as insufficiently serious, and imposed 30 years (a 20‑year upward variance).
On appeal, Flores‑Nater challenged substantive reasonableness; the First Circuit vacated and remanded for resentencing because the district court failed to articulate a plausible, case‑specific rationale for the large upward variance.

Issue	Plaintiff's Argument (Government)	Defendant's Argument (Flores‑Nater)	Held
Whether the 30‑year sentence is substantively reasonable given the guideline (120 months)	Government urged a lengthy sentence reflecting the crime’s seriousness and joined a 25‑year recommendation	30 years is greater than necessary; the sentence is substantively unreasonable	Vacated and remanded: sentence substantively unreasonable because the court failed to give a case‑specific plausible rationale
Whether the district court’s boilerplate statement satisfied the explanation requirement for a large upward variance	Boilerplate recitation of § 3553(a) factors suffices when record otherwise supports inference	Boilerplate is inadequate without case‑specific application	Boilerplate was inadequate; court must explain which specific facts justified the variance
Effect of parties’ joint 25‑year recommendation on review	Joint recommendation supports reasonableness but does not bind the court	Joint recommendation does not cure a lack of judicial explanation for a higher sentence	Court may exceed joint recommendation, but must explain why it imposed a harsher variance; absence of explanation required vacatur
