The Wrong Man with the Rifle: Fifth Circuit Finds Officer's Deadly-Force Mistake Was Constitutionally Reasonable

Martinez v. Hinojosa, (5th Cir. June 4, 2026)

TL;DR

The Fifth Circuit held that a police officer who mistakenly shot an innocent man during an active-shooter incident did not violate the Fourth Amendment because the officer's mistake was objectively reasonable under the circumstances. The court found that Officer David Hinojosa reasonably believed Jorge Martinez was the active shooter when Martinez emerged from a house carrying the suspect's rifle during an ongoing police gunfight. Because there was no constitutional violation, the officer received qualified immunity and the City of Laredo could not be liable under Monell.

Why it matters: This case reinforces that courts evaluate use-of-force decisions from the perspective of officers facing rapidly evolving threats, not with hindsight. Even tragic mistakes can be constitutionally reasonable when officers confront what appears to be an active shooter situation.

Limits of the ruling: The court emphasized the unique facts—an ongoing active-shooter event, an officer already wounded, and a man emerging from the scene carrying the shooter's rifle. This decision does not give officers blanket authority to use deadly force whenever a person possesses a firearm.

Facts

In the early morning hours of November 26, 2019, Laredo police officers responded to a domestic disturbance call. As officers arrived, Cesar Terrazas opened fire with an AR-15-style rifle, striking one officer in the leg. A gunfight ensued between Terrazas and responding officers.

During the exchange, Terrazas entered the home of Jorge Martinez. Once inside, Terrazas shot and wounded Martinez's mother. Martinez and his sister then managed to overpower and disarm Terrazas. Martinez removed the magazine from the rifle, effectively disabling it.

Officer David Hinojosa arrived during the unfolding crisis. He knew officers were engaged with an armed suspect and that an officer had already been shot. He established a defensive position approximately sixty yards away from the residence. At that point, he did not know the suspect's appearance, clothing, or identity.

A few minutes later, Martinez exited the residence completely naked while carrying Terrazas's rifle in his left hand. The record contained no explanation for why Martinez was unclothed. After exiting, Martinez reportedly yelled, "I am not the shooter." Two neighbors later testified they heard him make that statement. Officer Hinojosa maintained he did not hear it.

Martinez then moved between vehicles and into the street. After turning toward Officer Hinojosa, he was shot once in the abdomen. The shooting occurred approximately thirteen seconds after Martinez emerged from the house. Martinez survived but suffered severe injuries.

Martinez filed suit under 42 U.S.C. § 1983, alleging excessive force and municipal liability against the City of Laredo. The district court granted summary judgment for the defendants, and Martinez appealed.

Issues

1. Did Officer Hinojosa violate the Fourth Amendment by using deadly force against Jorge Martinez after mistakenly identifying him as the active shooter?

2. Did factual disputes about whether Officer Hinojosa heard Martinez yell "I am not the shooter" create a jury question that precluded summary judgment?

3. Could the City of Laredo be held liable under Monell if no underlying constitutional violation occurred?

Court's Decision (Holding)

The Fifth Circuit affirmed summary judgment for Officer Hinojosa and the City of Laredo.

The court held that although Martinez was seized under the Fourth Amendment, Officer Hinojosa's mistaken identification of Martinez as the shooter was objectively reasonable. Consequently, the use of deadly force did not violate the Constitution. Because there was no constitutional violation, qualified immunity applied and municipal liability was foreclosed.

Reasoning

1. Martinez Was Seized Under the Fourth Amendment

The court first determined that a Fourth Amendment seizure occurred because Officer Hinojosa intentionally applied force to Martinez, even though he mistakenly believed Martinez was someone else. Unlike cases involving innocent bystanders accidentally struck by gunfire, Martinez was the intended target of the officer's actions. Therefore, the shooting constituted a seizure.

However, establishing a seizure did not end the analysis. The critical question remained whether the seizure was reasonable.

2. Mistaken Identity Does Not Automatically Create a Constitutional Violation

The court emphasized that Fourth Amendment reasonableness often permits officers to act on probabilities rather than certainties. Officers are not required to be correct in every factual assessment; they must be reasonable.

Officer Hinojosa arrived during an active-shooter incident. He knew:

• An officer had already been shot.

• Gunfire had recently occurred.

• The suspect was armed with a rifle.

• A man carrying a rifle emerged from the location associated with the shooting.

Given those facts, the court concluded it was objectively reasonable for Hinojosa to believe Martinez was the gunman. The fact that Martinez was actually an innocent victim who had disarmed the suspect did not alter the constitutional analysis because courts evaluate force decisions from the perspective of the officer at the moment force is used.

3. The Dispute About "I'm Not the Shooter" Was Not Material

Martinez argued that witnesses heard him repeatedly yell that he was not the shooter and that a reasonable jury could conclude Officer Hinojosa heard the same thing. The Fifth Circuit agreed that witness testimony created a factual dispute regarding whether Hinojosa could have heard Martinez.

Nevertheless, the court found the dispute immaterial.

Even assuming Hinojosa heard Martinez's statement, the court held it would still have been reasonable for him to doubt its truth. An active shooter attempting to evade police could easily claim innocence. Under the circumstances, an officer was not constitutionally required to accept such a statement at face value.

4. The Threat Assessment Supported Deadly Force

The court described the active threat factor as the most important consideration in deadly-force cases.

Several facts supported the officer's perception of danger:

• Officers had recently been engaged in a gun battle.

• One officer had already been wounded.

• The person emerging from the residence possessed an assault-style rifle.

• The officer could not know whether the shooting had truly ended.

• Martinez moved into the street while carrying the rifle and turned toward the officer.

From Hinojosa's perspective, he was confronting an active shooter. The court concluded that deadly force was objectively reasonable under those circumstances.

5. No Warning Was Required Under These Circumstances

Martinez argued that Hinojosa should have issued a warning before shooting.

The court acknowledged that warnings are generally important when feasible. However, only thirteen seconds elapsed between Martinez's emergence from the residence and the shooting. Less than three seconds passed between Martinez entering the street and being shot.

The court held that the rapidly evolving circumstances made a warning impractical. Additionally, because Hinojosa arrived after other officers had already exchanged gunfire with the suspect, it was reasonable for him to assume any necessary warnings had effectively already been communicated through the ongoing confrontation.

6. No Underlying Constitutional Violation Meant No Monell Liability

Because the court found no Fourth Amendment violation, the municipal liability claim necessarily failed. A city cannot be liable under Monell when no constitutional violation occurred in the first place.

Street Takeaways

• Courts judge use-of-force decisions from the officer's perspective at the moment force is used, not based on facts discovered later.

• A mistaken identification can still result in a constitutionally reasonable use of force if the mistake itself is objectively reasonable.

• In active-shooter situations, the immediate-threat factor will often dominate the Fourth Amendment analysis.

• Even if a suspect or unknown individual verbally claims innocence, officers are not necessarily required to accept that claim when circumstances indicate an ongoing deadly threat.

• Officers are not required to wait until a firearm is actually pointed at them before taking action when the totality of circumstances reasonably indicates an imminent deadly threat.

• Failure-to-train and other municipal liability claims generally collapse if no underlying constitutional violation can be established.
