Co-Resident Consent and an Imminent Knife Threat: Upholding Warrantless Entry and Deadly Force

Case: Martinez v. Hidalgo County
Court: United States Court of Appeals for the Fifth Circuit
Date: October 15, 2026
Disposition: Summary judgment and denial of postjudgment relief affirmed.

Precedential qualification: The opinion is not designated for publication under Fifth Circuit Rule 47.5. Its significance lies principally in its application of existing doctrine to a recorded police encounter, rather than the announcement of a new, generally binding constitutional rule.

1. Introduction

Martinez v. Hidalgo County concerns the fatal shooting of Guillermo San Miguel Sanchez during a domestic-disturbance response at the home he shared with his mother. His family challenged the deputies’ warrantless entry, warrantless arrest, use of deadly force, and subsequent handcuffing. They also sought damages from Hidalgo County under federal civil-rights law and the Texas Tort Claims Act.

The central questions were whether Sanchez’s mother authorized entry into the home, whether the deputies had probable cause to arrest him for family violence, and whether his approach toward them while carrying a kitchen knife justified deadly force. A further procedural question concerned whether subsequently submitted policy materials and expert evidence required reopening the judgment.

The Fifth Circuit affirmed judgment for Deputies Brian Ayala and Juan Flores and Hidalgo County. Its reasoning connects several distinct doctrines: third-party consent to home entry, probable cause, the totality-of-the-circumstances assessment of police force, governmental immunity for intentional torts, and the demanding requirements for postjudgment reconsideration.

2. Background and Procedural History

The encounter

On October 6, 2021, Deputy Flores responded to a reported domestic dispute. Outside the residence, Maura Sanchez told him that her son had punched her, pushed her out of the house, and locked himself inside. She also reported that he had bipolar disorder, was not taking medication, and had recently received inpatient behavioral-health treatment. Deputy Ayala, who arrived shortly afterward, recalled seeing facial injuries.

Initially, Mrs. Sanchez indicated that her daughter was coming and might persuade Sanchez to open the door voluntarily. The daughter had previously helped calm him. The deputies nevertheless continued their attempts to communicate with Sanchez. After Ayala approached a bedroom window, glass shattered and further sounds of destruction came from inside.

As the deputies approached the front entrance, their body cameras recorded a woman repeatedly directing them in Spanish to break down the door. Both deputies attributed those instructions to Mrs. Sanchez. They forced entry, announced their presence, and encountered Sanchez holding an eight-inch kitchen knife.

The deputies repeatedly instructed Sanchez to drop the knife and not approach them. Sanchez refused, demanded that they leave, and intermittently closed his bedroom door. After remaining inside for a little over a minute, he opened the door and advanced toward the deputies while still carrying the knife. They fired eleven shots, stopping when he turned and fell. They then handcuffed him, secured the knife, and rendered medical assistance. Sanchez died that day.

The litigation

Guillermo San Miguel Martinez and Maura Sanchez, individually and as representatives of Sanchez’s estate, together with other family members, pursued wrongful-death and survival claims. The defendants removed the action from Texas state court to federal court.

The district court granted summary judgment on all claims and dismissed them with prejudice. It held that the Texas Tort Claims Act did not waive immunity for claims arising from intentional conduct and that the deputies had committed no Fourth Amendment violation. It subsequently denied a motion to alter or amend the judgment under Federal Rule of Civil Procedure 59(e).

Although the postjudgment motion asserted several grounds, the appeal concerning that motion focused on newly offered evidence. The Fifth Circuit affirmed both challenged orders.

3. Summary of the Opinion

  • Texas tort claims: Allegations concerning the intentional shooting and handcuffing could not be converted into negligence claims to obtain a statutory waiver of governmental immunity.
  • Home entry: Mrs. Sanchez had common authority over the residence, and the record did not create a genuine factual dispute that she authorized the deputies to break down the door.
  • Arrest: Her account of assault, observed injuries, and the surrounding circumstances established probable cause for an arrest involving family violence.
  • Deadly force: Sanchez’s armed approach, considered alongside his conduct, proximity, and the confined and obstructed surroundings, presented a serious physical threat that made the shooting objectively reasonable.
  • Handcuffing: The identified cuff marks and finger cuts were insufficient to establish the separate excessive-force claim.
  • County liability: Without an underlying constitutional violation, the federal claims against the county also failed.
  • Reconsideration: The additional evidence would not change the result, and the plaintiffs inadequately explained why they had not submitted it before judgment.

4. Analysis: Precedents Cited and Legal Reasoning

A. Summary judgment, video evidence, and the standard of review

Under DeVoss v. Sw. Airlines Co., 903 F.3d 487, 490 (5th Cir. 2018), the court reviewed summary judgment de novo: it independently applied the same legal standard as the district court. Rule 56 required judgment for the defendants if no genuine dispute of material fact remained and they were entitled to judgment as a matter of law.

Carnaby v. City of Houston, 636 F.3d 183, 187 (5th Cir. 2011), supplied the ordinary requirement to construe facts favorably to the nonmoving party, together with the importance of contemporaneous recordings. Through Scott v. Harris, 550 U.S. 372 (2007), the court explained that a factual account need not be accepted when the record blatantly contradicts it so that no reasonable jury could believe it.

The recordings therefore performed two roles: they established much of the encounter’s sequence and constrained factual assertions inconsistent with what they captured. But this principle is not a general license to resolve every ambiguity against a plaintiff merely because a recording exists. The relevant question remains what the recording actually establishes.

Two additional precedents supported the rejection of speculative disputes. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 586 (1986), requires more than “metaphysical doubt” about material facts. Little v. Liquid Air Corp., 37 F.3d 1069, 1075 (5th Cir. 1994) (en banc), explains that favorable inferences require an actual evidentiary controversy. Its reliance on Lujan v. Nat'l Wildlife Fed'n, 497 U.S. 871, 888 (1990), reinforces that courts cannot assume an opponent will later produce missing proof. These authorities became particularly important to the dispute over who authorized entry.

B. The Texas Tort Claims Act: substance controls over negligence labels

The plaintiffs invoked Texas Civil Practice and Remedies Code § 101.021(2), which permits certain claims involving injury or death caused by the condition or use of tangible personal property. Their theory characterized the guns and bullets as negligently used property. Section 101.057(2), however, preserves immunity for claims arising from intentional torts.

Aguirre v. City of San Antonio, 995 F.3d 395, 422 (5th Cir. 2021), established that intentional conduct remains within that exception regardless of pleading terminology. The opinion traced that principle to Tex. Dep't of Pub. Safety v. Petta, 44 S.W.3d 575, 580 (Tex. 2001): a claimant cannot obtain a waiver simply by describing intentional conduct as negligence.

The more specific police-force authorities were Quinn v. Guerrero, 863 F.3d 353, 364 (5th Cir. 2017), and City of Watauga v. Gordon, 434 S.W.3d 586, 593 (Tex. 2014). They treat excessive-force claims arising during a lawful arrest as sounding in battery rather than negligence, even where the allegedly excessive character of the force was not intended.

Those precedents foreclosed the plaintiffs’ characterization of this shooting. The same reasoning applied to handcuffing: under Aguirre v. City of San Antonio, intentionally applying restraints is intentional conduct. The county consequently retained immunity.

This statutory analysis was distinct from the constitutional analysis. The immunity exception turned on the nature of the alleged conduct, not simply on whether the force ultimately satisfied the Fourth Amendment.

C. Qualified immunity: the court decided the constitutional merits

Pearson v. Callahan, 555 U.S. 223, 231, 236 (2009), drawing on Harlow v. Fitzgerald, 457 U.S. 800, 818 (1982), supplied the qualified-immunity framework. The inquiry asks whether the official violated a federal right and whether that right was clearly established at the relevant time. Courts may address either question first.

Aguirre v. City of San Antonio, relying on Darden v. City of Fort Worth, 880 F.3d 722, 727 (5th Cir. 2018), explained the plaintiff’s burden after an official invokes qualified immunity at summary judgment: the plaintiff must establish a genuine factual issue concerning conduct violating clearly established law.

Here, the court resolved the first question. It found no constitutional violation in the entry, arrest, shooting, or handcuffing. It therefore did not decide whether sufficiently specific precedent had clearly established the unlawfulness of the deputies’ conduct in October 2021.

This distinction matters: the decision is not merely that the deputies escaped damages because existing law gave inadequate notice. The court held that their conduct, on the record presented, satisfied the Fourth Amendment.

D. Warrantless entry: common authority and later consent

The governing precedents

Wernecke v. Garcia, 591 F.3d 386, 393 (5th Cir. 2009), recognizes the presumptive unreasonableness of warrantless home searches absent an applicable exception. United States v. Watson, 273 F.3d 599, 602 (5th Cir. 2001), identifies consent and exigent circumstances as grounds permitting an otherwise warrantless in-home arrest.

For third-party authority, the court relied on Harris v. Serpas, 745 F.3d 767, 773–74 (5th Cir. 2014), which recognized that a person sharing common control over premises may consent to police entry. The opinion acknowledged that Harris v. Serpas was abrogated on other grounds by Barnes v. Feliz, 605 U.S. 73 (2025), without treating its common-authority principle as displaced.

Gates v. Tex. Dep't of Protective & Regul. Servs., 537 F.3d 404, 420 (5th Cir. 2008), required consideration of the totality of the circumstances. Quoting Florida v. Jimeno, 500 U.S. 248, 251 (1991), it also supplied the objective measure of consent’s scope: what a typical reasonable person would understand from the exchange.

Mrs. Sanchez’s authority

The evidence established that Mrs. Sanchez lived in the home. Her own statements and witness affidavits supported that fact. As a co-resident who ordinarily had access and authority to invite others inside, she possessed common control.

Her temporary inability to enter did not extinguish that authority. Being locked out by another occupant was different from lacking residential rights. Likewise, a later search warrant’s failure to identify her as a person controlling the property did not contradict her residency because the warrant did not purport to list every resident.

The disputed instruction to break down the door

The court treated Mrs. Sanchez’s initial request to wait for her daughter and the later instruction to force entry as sequential, not irreconcilable. The intervening destruction inside the home supplied context for a change of mind.

The plaintiffs did not dispute the translation of the instruction. They instead disputed the speaker’s identity. The interpreter could not identify the voice, and other women were present. Both deputies, however, identified Mrs. Sanchez as the speaker. The court concluded that the interpreter’s inability to identify someone did not contradict that affirmative evidence.

Witness affidavits generally stated that Mrs. Sanchez had not consented and had requested delay. But they did not specifically deny that she later shouted the recorded instruction, identify another speaker, or claim that the affiants themselves had spoken. Applying the summary-judgment precedents, the court found no genuine factual dispute.

The analytical distinction is important: the recordings conclusively established that the instruction was given, while attribution depended on the deputies’ accounts and the absence of sufficiently specific contrary evidence. The decision should not be read as establishing that every unidentified voice near a residence can supply valid consent.

Because consent resolved the entry issue, the court expressly declined to decide whether exigent circumstances independently justified entry.

E. Warrantless arrest: probable cause and lawful home access are separate questions

Glenn v. City of Tyler, 242 F.3d 307, 313 (5th Cir. 2001), supplied the requirement that an arrest rest on a valid warrant or probable cause. Quoting Goodson v. Corpus Christi, 202 F.3d 730, 740 (5th Cir. 2000), it also recognized qualified immunity where a reasonable official could believe probable cause existed.

District of Columbia v. Wesby, 583 U.S. 48, 56–61 (2018), characterizes probable cause as a practical, relatively low threshold requiring a probability or substantial chance of criminal activity. Terrell v. Allgrunn, 114 F.4th 428, 434 (5th Cir. 2024), applied that totality-based inquiry from the perspective of an objectively reasonable officer.

Mrs. Sanchez’s report that her son punched and pushed her, Ayala’s observation of facial injuries, and the deputies’ observations of destructive behavior supported probable cause. The court also relied on Texas Family Code § 71.004(1), defining family violence, and Texas Code of Criminal Procedure article 14.03(a)(4), authorizing warrantless arrests upon probable cause for an offense involving family violence.

Importantly, the state arrest authority did not itself resolve the constitutional protection of the home. The opinion addressed that separate obstacle through consent. Together, valid entry and probable cause defeated the unlawful-arrest theory.

F. Deadly force: totality of the circumstances and a serious physical threat

The controlling framework

Aguirre v. City of San Antonio, drawing on Tolan v. Cotton, 572 U.S. 650, 656 (2014), located the excessive-force claim in the Fourth Amendment’s protection against unreasonable seizures. The required elements were injury, causation by police force, and objective unreasonableness. Only the third was disputed as to the shooting.

Barnes v. Feliz, 605 U.S. 73, 79–80 (2025), required evaluation of the totality of the circumstances known to the officer. The opinion accordingly considered more than Sanchez’s final movement: it discussed the reported assault, property destruction, repeated commands, knife possession, prior interactions, physical proximity, and the condition of the interior.

The serious-threat standard came from Elizondo v. Green, 671 F.3d 506, 510 (5th Cir. 2012), citing Tennessee v. Garner, 471 U.S. 1, 11 (1985): deadly force is constitutionally permissible when a suspect threatens serious physical harm to officers or others.

Why the court considered the threat sufficient

Elizondo v. Green supplied the closest factual analogy. There, an officer encountered a teenager holding a knife during a mental-health emergency. The teenager refused commands, moved toward the officer, and raised the knife threateningly. The court held that the officer reasonably perceived a serious threat.

The panel considered Sanchez’s case materially similar. He retained a large knife, repeatedly refused instructions, displayed hostility, and ultimately approached the deputies in a confined space. Debris complicated their ability to move safely. Together, those circumstances supported a reasonable belief that he was about to stab them.

The plaintiffs disputed whether Sanchez pointed the knife toward the deputies or downward. The court accepted that the knife’s direction could be disputed but concluded that the distinction did not change the result under the surrounding circumstances.

This was a fact-specific conclusion, not a categorical rule that possessing a knife justifies being shot. The court relied on possession combined with approach, proximity, prior conduct, and restricted movement. Similarly, Sanchez’s mental illness was part of the context, but the court did not find that it eliminated the physical threat presented at the time of firing.

Retreat, alternatives, and the number of shots

Under Ramirez v. Knoulton, 542 F.3d 124, 129–30 (5th Cir. 2008), officers are not invariably required to attempt alternative methods before responding to a serious threat with deadly force. The governing question remains reasonableness. Here, the sudden approach and risk of tripping on debris supported the decision not to retreat or first employ nonlethal measures.

Plumhoff v. Rickard, 572 U.S. 765, 777 (2014), established that officers justified in firing need not stop before the threat ends. Garza v. Briones, 943 F.3d 740, 747–48 (5th Cir. 2019), applied that principle despite sixty-one shots because firing ceased when the suspect fell and no longer threatened officers.

Those decisions defeated the argument that eleven shots, by number alone, established excessiveness. The material point was that Ayala and Flores stopped when Sanchez turned and fell. The reasoning would not automatically protect additional shots fired after a threat had ended.

The separate handcuffing claim

Freeman v. Gore, 483 F.3d 404, 416–17 (5th Cir. 2007), required more than a de minimis injury and rejected a claim based on bruising from tight restraints. Glenn v. City of Tyler, 242 F.3d at 314, likewise held that tight handcuffing, without more, does not establish excessive force.

The autopsy’s cuff marks and finger cuts did not satisfy that requirement here. This ruling addressed the particular injuries and claim presented; it did not establish that every use of restraints after a shooting is necessarily reasonable.

G. County liability: the missing underlying constitutional violation

The federal county claims included both direct claims and official-capacity claims against the deputies. Will v. Mich. Dep't of State Police, 491 U.S. 58, 71 (1989), supplied the principle that an official-capacity claim is effectively a claim against the governmental entity.

Monell v. Dep't of Soc. Servs., 436 U.S. 658 (1978), provided the framework for local-government liability under § 1983. The decisive limitation came from Doe ex rel. Magee v. Covington Cnty. Sch. Dist. ex rel. Keys, 675 F.3d 849, 866–67 (5th Cir. 2012), and Elizondo v. Green, 671 F.3d at 510–11: without an underlying constitutional violation, an essential element of municipal liability is absent.

Because the court found no Fourth Amendment violation, the county claims failed without further analysis of policy or training deficiencies. This was not an extension of the deputies’ personal qualified immunity to the county. It was an independent failure to establish the constitutional predicate for municipal liability.

H. Rule 59(e): additional evidence must be material and timely presented

Why review was de novo

Templet v. HydroChem Inc., 367 F.3d 473, 477 (5th Cir. 2004), distinguishes between a district court’s refusal to consider additional materials and its consideration of them while leaving summary judgment intact. The former receives abuse-of-discretion review; the latter receives de novo review.

The district court had explained why the additional evidence would not affect the outcome. Because it actually considered the materials, the Fifth Circuit independently reviewed the resulting determination. The opinion therefore does not establish de novo review for every Rule 59(e) denial.

The governing reconsideration principles

Rollins v. Home Depot USA, Inc., 8 F.4th 393, 396 (5th Cir. 2021), quoting Faciane v. Sun Life Assurance Co. of Canada, 931 F.3d 412, 423 (5th Cir. 2019), described Rule 59(e)’s narrow purpose: correcting manifest legal or factual errors or presenting newly discovered evidence.

Templet v. HydroChem Inc. further characterized reconsideration as an extraordinary remedy. Drawing on Lavespere v. Niagara Mach. & Tool Works, Inc., 910 F.2d 167, 174 (5th Cir. 1990), it identified relevant considerations: the reason for the omission, the evidence’s importance, its prior availability, and potential unfair prejudice. The opinion noted that Lavespere v. Niagara Mach. & Tool Works, Inc. was abrogated on other grounds by Little v. Liquid Air Corp..

The policy and expert materials

The plaintiffs relied on the county’s “High Risk Situation” policy and training coordinator David Muniz’s testimony. They argued that the deputies had failed to follow procedures governing barricaded individuals. The defendants disputed both that interpretation and the policy’s applicability.

The court assumed that a factual dispute about compliance might exist but found it insufficient to alter the constitutional result. Internal policy and constitutional reasonableness were not interchangeable: even possible policy noncompliance did not, on this record, negate the serious physical threat Sanchez presented.

Police-practices expert Roger Chappell’s opinions also did not establish a new material factual dispute. The court characterized his submission as evaluating existing evidence and offering conclusions about consent and reasonableness rather than supplying outcome-changing facts.

Photogrammetry expert Angelos Leiloglou’s statement that the knife pointed downward likewise did not change the analysis. The court had already considered that version of the knife’s orientation and found the shooting reasonable in the broader circumstances.

The unexplained delay

Independently, the materials had been available weeks before the June 30, 2025 summary-judgment order. The plaintiffs did not adequately explain why they failed to seek supplementation before judgment.

ICEE Distribs., Inc. v. J&J Snack Foods Corp., 445 F.3d 841, 847–48 (5th Cir. 2006), quoting Templet v. HydroChem Inc., confirmed that an unexcused failure to present available evidence provides a valid reason to deny reconsideration. Both lack of materiality and lack of diligence therefore supported affirmance.

5. Impact and Limits

Consent disputes will turn on specific evidence

The opinion illustrates that temporary exclusion from a shared home does not necessarily remove a resident’s authority to consent to entry. It also shows why witnesses should describe the precise sequence and words exchanged, rather than offer only a general conclusion that “no consent” was given.

Its limit is equally important: the court did not decide a case involving established exclusive control by another occupant, affirmative evidence identifying a different speaker, or an unresolved exigency theory.

Video evidence remains powerful but proposition-specific

Recordings can establish conduct and defeat incompatible accounts, but their significance depends on what they actually capture. Here, the recorded instruction, witness attribution, and lack of specific contradiction worked together. The opinion should not be treated as making all inferences from body-camera footage conclusive.

Deadly-force analysis remains contextual after Barnes

The court expressly applied the totality-of-the-circumstances framework from Barnes v. Feliz. Its result demonstrates that broader consideration of an encounter does not necessarily make force unreasonable where the final approach presents a serious threat. Conversely, it does not establish that preceding decisions, opportunities to de-escalate, or alternative tactics are always irrelevant.

Policy violations and constitutional violations remain distinct

The decision limits efforts to treat departmental policy as the constitutional standard itself. Nevertheless, it does not make policy evidence categorically immaterial. The panel held only that the disputed policy evidence did not change the outcome on these facts.

Postjudgment motions are not substitutes for developing the record

The procedural lesson is particularly practical: parties should promptly seek to supplement the summary-judgment record when material evidence becomes available. Evidence newly submitted after judgment is not necessarily newly discovered, and an unexplained delay can independently defeat reconsideration.

Because the opinion is unpublished, these implications should be understood as persuasive applications of the authorities it cites, subject to the limits governing unpublished Fifth Circuit decisions.

6. Complex Concepts Simplified

Summary judgment
A decision without trial when no genuine dispute over an outcome-relevant fact requires a jury’s resolution.
Common authority
Shared use and control of property that permits a co-occupant to authorize entry. Ownership is not essential, and being temporarily locked out does not necessarily eliminate it.
Probable cause
A reasonable basis to believe an offense probably occurred—not proof beyond a reasonable doubt.
Objective reasonableness
Whether a reasonable officer, considering the circumstances known at the time, could regard the force as justified. An officer’s personal fear is relevant context but does not alone decide the issue.
Qualified immunity
A defense protecting officials from damages unless their conduct violates clearly established federal rights. Here, the court found no rights violation in the first place.
Monell liability
A local government’s own liability under § 1983, rather than automatic liability merely because it employed the officers. The claims here failed because no underlying constitutional violation was established.
De minimis injury
An injury the court considers too minor to satisfy the applicable claim’s injury requirement. The court placed the identified handcuff injuries in that category.
Rule 59(e)
A limited mechanism for asking a court to alter a judgment, not a routine opportunity to submit evidence that could have been presented earlier.

7. Conclusion

Martinez v. Hidalgo County upheld the deputies’ actions through three separate conclusions: a co-resident authorized entry, probable cause supported arrest, and the armed approach justified deadly force under the total circumstances. Those findings also defeated municipal liability, while the intentional-tort exception barred the Texas statutory claims.

The opinion’s broader lesson is evidentiary and contextual: specific contradictions matter more than speculative doubt, constitutional standards do not simply mirror departmental policy, and postjudgment evidence must be both consequential and supported by an adequate explanation for its late presentation.
