5th Cir.

Martinez v. Hinojosa

June 4, 2026 ·24-40535 ·Panel Decision ·Leslie H. Southwick · By Aisha Johnson

The Fifth Circuit affirmed a district court ruling that no Fourth Amendment violation occurred when an officer shot a man he mistakenly believed to be an active shooter. The court held that the officer's split-second decision to use deadly force was objectively reasonable under the totality of the circumstances.

Background

In November two thousand nineteen, Officer David Hinojosa responded to a domestic disturbance where a suspect named Cesar Terrazas had opened fire on police. Terrazas entered the home of the plaintiff, Jorge Martinez, and shot Martinez’s mother before being disarmed by Martinez. Officer Hinojosa arrived shortly after, saw a naked man exit the residence holding a rifle, and shot him. The plaintiff later sued under Section one thousand nine hundred eighty-three, alleging excessive force and failure to train. The district court granted summary judgment, finding no constitutional violation and granting qualified immunity to the officer.

The court’s reasoning

The Fifth Circuit reviewed the case de novo, applying the standard for summary judgment. The court first determined that a seizure occurred under the Fourth Amendment because physical force was intentionally applied to the plaintiff. The court then analyzed whether the seizure was reasonable. The court emphasized that reasonableness is judged from the perspective of a reasonable officer on the scene, not with hindsight. The court found that Officer Hinojosa reasonably believed the plaintiff was the active shooter who had just wounded a colleague. The court noted that even if the officer heard the plaintiff shouting he was not the shooter, it was reasonable for the officer to suspect the claim was a lie to evade capture. The court also found that the severity of the crime, the immediate threat to safety, and the lack of time to issue a warning justified the use of deadly force. Because no constitutional violation occurred, the court held that the City of Laredo could not be held liable under Section one thousand nine hundred eighty-three.

As lamentable as these events certainly were, we agree with the district court that no constitutional violation occurred on the specific facts of this case.

What it means going forward

The ruling reinforces that officers are protected by qualified immunity when they make reasonable mistakes of identity in high-stakes, rapidly evolving situations involving active shooters. It clarifies that the reasonableness of an officer’s perception of an imminent threat is the controlling factor, not the actual innocence of the victim.
