18 U.S.C. §§ 111 & 1114: Subcontracted Private Personnel Assisting Federal Detention Functions Are Protected Without a Direct Federal Contract

I. Introduction

United States v. Hernandez addresses the reach of federal officer-assault statutes in the modern detention ecosystem, where federal detainees are often housed in privately operated or locally run facilities under contract with the United States Marshals Service (“Marshals Service”). The defendant, Anthony A. Hernandez, a federal pretrial detainee housed at Cibola County Correctional Center (“Cibola”), assaulted J.F., an employee of JTF Consulting and Security International, LLC (“JTF”). JTF contracted with CoreCivic, the private operator of Cibola, but JTF had no direct contract with the Marshals Service.

The appeal presented a focused statutory question with major practical consequences: whether J.F. was within the class protected by 18 U.S.C. §§ 111 and 1114 as a “person assisting” federal officers “in the performance of official duties,” such that Hernandez’s assault could be tried and punished in federal court.

II. Summary of the Opinion

The Tenth Circuit affirmed Hernandez’s conviction under 18 U.S.C. § 111(a) and (b). The court held that the evidence permitted a rational jury to find that:

• J.F. was acting within the scope of his assigned duties at Cibola (not “acting independently” or on a “personal frolic”); and
• J.F. was “assisting” the Marshals Service in performing a federal detention function—housing and supervising federal pretrial detainees—at the time of the assault.

Critically, the court rejected the argument that coverage turns on whether the victim had a direct contractual relationship with a federal agency. The statute’s text requires assistance to federal officers/functions, not privity of contract with the federal government.

III. Analysis

A. Precedents Cited

1. Foundational purpose: protecting federal officers and federal functions

The opinion anchored its interpretation in United States v. Feola, 420 U.S. 671 (1975), which the court cited for two related propositions:

• Congress intended § 111 “to protect both federal officers and federal functions”; and
• the statute ensures a federal forum for offenses implicating federal officers/functions.

By framing detention of federal pretrial detainees as a “federal function,” the panel treated the case as squarely within Feola’s rationale even though the immediate workplace and employer were private.

2. The Tenth Circuit’s interpretive framework for “official duties”

The court relied heavily on United States v. Holder, 256 F.3d 959 (10th Cir. 2001). Holder supplies the governing method:

• There is “no bright-line test” for “performance of official duties” (Holder, quoting United States v. Hoy, 137 F.3d 726 (2d Cir. 1998));
• the inquiry is whether the person is acting “within the scope of what the agent is employed to do” (Holder, quoting United States v. Hoffer, 869 F.2d 123 (2d Cir. 1989));
• courts distinguish official activity from a “personal frolic” (Holder, quoting Hoffer); and
• the phrase “while engaged... in the performance of official duties” is interpreted “liberally and with flexibility.”

Holder also provided the procedural lens: the panel treated Hernandez’s “jurisdiction” objection as a sufficiency-of-the-evidence challenge (Holder), applying de novo review of the acquittal denial.

3. Private detention personnel as covered “assisting” victims

The opinion found persuasive its own unpublished decision, United States v. Ama, 97 F. App'x 900 (10th Cir. 2004) (unpublished), which had addressed whether a privately employed corrections officer, acting pursuant to a contract to assist the Marshal, falls within § 111’s protection. Ama, in turn, relied on:

• United States v. Jacquez- Beltran, 326 F.3d 661 (5th Cir. 2003); and
• United States v. Murphy, 35 F.3d 143 (4th Cir. 1994).

Hernandez extends the functional logic of Ama to a subcontracted consultant performing rounds—emphasizing role and function over formal employment status or the identity of the contractual counterparty.

4. Illustrative “official duties” cases showing breadth and flexibility

To demonstrate the established breadth of “official duties,” the court listed examples previously discussed in Holder:

• United States v. Hohman, 825 F.2d 1363 (9th Cir. 1987) (off-duty park ranger enforcing park rules);
• United States v. Reid, 517 F.2d 953 (2d Cir. 1975) (off-duty DEA officer overhearing a robbery);
• United States v. Streich, 759 F.2d 579 (7th Cir. 1985) (IRS agent repossessing a car);
• United States v. Boone, 738 F.2d 763 (6th Cir. 1984) (per curiam) (judge walking to courthouse on Sunday to research);
• United States v. Lopez, 710 F.2d 1071 (5th Cir. 1983) (federal agent detaining a state-charged suspect);
• United States v. Hoy, 137 F.3d 726 (2d Cir. 1998) (off-duty deputy marshal intervening in a street fracas).

These cases served a rhetorical and doctrinal function: if “official duties” can include off-duty intervention and situational law-enforcement responses, then it can surely include routine rounds directly tied to federal detainee custody.

5. Tenth Circuit examples of “assisting” relationships beyond formal federal employment

The panel also cited Tenth Circuit authority recognizing a wide range of “assisting” victims:

• United States v. Reed, 413 F.2d 338 (10th Cir. 1969) (probation officer orally employed by a Marshal to assist transportation);
• United States v. Martin, 163 F.3d 1212 (10th Cir. 1998) (city detective “deputized to participate in a federal investigation”);
• United States v. Holder, 256 F.3d 959 (10th Cir. 2001) (private citizen killed while helping a federal employee with a federally funded and approved fence project).

Together, these cases undercut any narrow reading that would require direct federal employment or a formal written contract with the United States.

6. Standard of review and sufficiency framing

Finally, the court cited United States v. Alexander, 817 F.3d 1205 (10th Cir. 2016) (quoting United States v. Rodella, 804 F.3d 1317 (10th Cir. 2015)) for the sufficiency standard: viewing evidence in the light most favorable to the government and asking whether a rational juror could find the elements beyond a reasonable doubt.

B. Legal Reasoning

1. The “federal function” was detention supervision of federal pretrial detainees

The court treated the relevant federal function as straightforward: the Marshals Service had contracted with Cibola to house federal pretrial detainees, including Hernandez. Security rounds—checking inmates and inspecting cells—directly support that federal detention mission.

2. “Assisting” does not require direct privity with a federal agency

Hernandez’s central argument was formal: J.F. worked for JTF; JTF contracted with CoreCivic; CoreCivic operated Cibola; only Cibola (via CoreCivic) contracted with the Marshals Service. Therefore, Hernandez argued, J.F. was too far removed from federal officers to be a protected victim.

The court rejected that privity-based test as inconsistent with:

• Text: § 1114 protects “any person assisting such an officer or employee in the performance of such duties.” Nothing in that phrase requires a direct contract with the United States.
• Purpose: Feola’s federal-function rationale would be undermined if federal protection evaporated whenever detention is delegated through layers of contracting.
• Precedent: Holder/Reed/Martin show that assistance relationships can be informal, indirect, or situational.

3. Scope-of-duties evidence supported the jury’s finding

The panel emphasized facts supporting “scope” and negating “independent” action:

• The warden asked J.F. to assist with day-to-day tasks (including rounds) due to personnel shortages.
• J.F.’s contract included a catch-all for “[s]uch other services as agreed to by the parties,” supporting that rounds could be within his assigned duties at Cibola.
• At the moment of assault, J.F. was performing routine custody/safety operations (rounds, cell inspection, removing an extra mattress).

On that record, the court concluded a reasonable jury could find J.F. was (1) acting within the scope of his duties and (2) assisting federal detention functions tied to the Marshals Service contract.

C. Impact

1. Practical expansion/clarification in contract-layer detention settings

Hernandez clarifies that § 111/§ 1114 coverage extends to individuals who help carry out federal detention responsibilities even when their employment and contracting chain is indirect (e.g., subcontractors, consultants, or auxiliary staff working through a private operator). This matters because modern federal detention often relies on intergovernmental service agreements and private-operation contracts with layered vendors.

2. Reduced incentive for formalism in victim-status litigation

By rejecting a direct-contract requirement, the opinion discourages defendants from reframing § 111 cases into corporate-structure disputes. The question becomes functional and fact-specific: what was the victim doing, and did it assist federal duties/functions at the time?

3. Litigation focus going forward: “assistance” and “scope” as fact questions

The panel’s approach makes two issues central in future cases:

• Functional nexus: whether the task meaningfully advances a federal officer’s duties or a federal function (here, federal pretrial detention).
• Scope of duties: whether the person was acting within assigned responsibilities versus acting independently.

Expect more evidentiary development at trial about job assignments, facility directives, and contractual scope clauses (like the catch-all here), because those facts will drive sufficiency outcomes.

IV. Complex Concepts Simplified

• “Official victim” (in this context): Not only federal officers, but also people protected by § 1114—especially “any person assisting” federal officers in their duties.
• “Federal function”: A task that carries out federal governmental responsibilities (here, custody and supervision of federal pretrial detainees), even if performed in a non-federal facility by private personnel.
• “Assisting”: Helping federal officers perform their duties; Hernandez holds this can be satisfied without direct employment or a direct federal contract.
• “Scope of official duties” / “personal frolic”: A flexible, fact-based inquiry: was the person doing what they were tasked to do for work purposes, or were they acting for purely personal reasons unrelated to the job?
• Sufficiency review: On appeal, the court asks whether any rational juror could find the elements beyond a reasonable doubt, viewing the evidence in the government’s favor.

V. Conclusion

United States v. Hernandez reinforces a functional, purpose-driven reading of 18 U.S.C. §§ 111 and 1114: when federal pretrial detainees are housed under a Marshals Service contract, personnel carrying out core detention tasks—such as security rounds and cell inspections—may be protected as persons “assisting” federal officers/functions, even if they are employed by a subcontractor and lack a direct contractual relationship with the federal government. The decision fits within the Tenth Circuit’s flexible “official duties” framework from United States v. Holder and the Supreme Court’s federal-function emphasis in United States v. Feola, and it will likely strengthen federal prosecutorial authority over assaults occurring in privatized or contract-layer detention environments.
