Not every tragedy involving law enforcement gives rise to a lawsuit. Even when officers voluntarily assist someone in crisis, determining whether they can later be held legally responsible for that person’s injuries or death is often far more complex than it appears.
Those issues were at the center of Moller v. County of San Bernardino (2026), where the Ninth Circuit Court of Appeals considered whether a sheriff’s deputy could be held liable after allowing an impaired man to leave her patrol vehicle shortly before he was struck and killed by a moving train.
Although the lawsuit involved federal civil rights claims rather than a traditional personal injury case, the decision provides important guidance for attorneys and families evaluating potential wrongful death and government liability claims. It also highlights the significant legal protections that often apply when lawsuits are brought against law enforcement officers and public entities.
How the Incident Began
The case began after sheriff’s deputies responded to a report from a hospital regarding a man who had been discharged but remained on the property.
A deputy located the man and offered to give him a courtesy ride home. After following his directions to a residence, it became unclear whether he actually lived there. During the encounter, the deputy also learned he had a history of drug- and theft-related arrests and concluded that he needed additional medical attention.
Rather than leaving him there, she decided to drive him to a nearby hospital.
What Happened During the Ride?
While driving to the hospital, the passenger repeatedly demanded to leave the vehicle.
At first, the deputy refused. She explained that it would be unsafe to leave him where they were and said she intended to take him to a hospital instead.
The passenger continued insisting that he be allowed out and threatened to make a mess inside the patrol vehicle.
Eventually, the deputy pulled over and allowed him to exit.
After she drove away, the man ran toward a moving train in an apparent attempt to climb aboard. He was fatally injured. An autopsy later found he was under the influence of drugs.
The Legal Claims Against the Deputy and the County
The deceased’s mother filed a federal civil rights lawsuit against the deputy and San Bernardino County.
She argued that once the deputy chose to transport her son to a hospital, she assumed responsibility for his safety. According to the lawsuit, allowing him to leave the patrol vehicle while he was impaired placed him in a dangerous situation that ultimately led to his death.
The lawsuit relied on two primary legal theories.
Did the Deputy Assume Responsibility for His Safety?
The family argued that by placing the man in her patrol vehicle and agreeing to transport him to a hospital, the deputy assumed a duty to protect him until he reached medical care.
Did the Deputy Create or Increase the Danger?
The family also argued that the deputy’s own actions made the situation more dangerous than it otherwise would have been by allowing an impaired individual to leave the vehicle near active railroad tracks.
Why the Court Ruled the Deputy Was Shielded from Liability
The Ninth Circuit Court of Appeals affirmed summary judgment in favor of both the deputy and San Bernardino County.
The court concluded that the deputy was protected by qualified immunity on the federal civil rights claims because existing law did not clearly establish that her actions violated the Constitution.
The court explained several reasons for its decision.
A Courtesy Ride Did Not Create Legal Custody
The court explained that a constitutional duty to protect someone generally arises only when the government significantly restrains that person’s freedom, such as through an arrest or incarceration.
Because the man voluntarily accepted a brief courtesy ride and was not under arrest or otherwise detained, the court concluded that this type of custodial relationship never existed.
The Harm Was Not Considered an Obvious Consequence
The court also determined that it was not a known or obvious consequence that the man would attempt to board a moving train after leaving the patrol vehicle.
Because that tragic outcome was not sufficiently foreseeable, the majority concluded that the deputy had not violated the Constitution under the state-created danger doctrine.
The Deputy Faced a Difficult Choice
The court also noted that the deputy lacked probable cause to arrest or involuntarily detain the passenger.
According to the majority, she faced a difficult decision: either allow him to leave when he demanded or unlawfully keep him in the vehicle without legal authority.
The court concluded that those circumstances supported granting qualified immunity.
Why One Judge Disagreed
The decision was not unanimous.
In a dissenting opinion, one judge argued that a jury—not the court—should have decided the case.
The judge emphasized that the deputy knew the man was physically impaired, struggling to walk, and experiencing drug withdrawal. The judge also noted that she was aware of the nearby moving train and had already decided the man needed medical care.
Under those circumstances, the judge concluded that allowing him to leave the patrol vehicle could reasonably be viewed as placing him in a more dangerous situation.
What This Decision Means for Wrongful Death and Personal Injury Cases
Although Moller involved federal civil rights claims, it provides important guidance for attorneys evaluating wrongful death and catastrophic injury claims involving public entities.
One of the biggest lessons is that lawsuits against government employees are often governed by legal protections that do not apply in ordinary negligence cases.
The decision also illustrates an important distinction courts frequently make. Government agencies generally are not liable simply because they failed to prevent harm. Instead, courts often focus on whether a public employee’s own actions affirmatively created or increased the danger that resulted in the injury.
For attorneys evaluating potential claims against law enforcement or other public entities, questions like these are often critical:
- Did the government employee create or increase the risk of harm?
- Was the injured person in the government’s legal custody?
- Did the government have legal authority to prevent the person from leaving?
- Do qualified immunity or other statutory protections apply?
The answers to those questions may determine whether a case proceeds to trial or is dismissed before a jury ever hears the evidence.
The Legal Takeaway
The Ninth Circuit ultimately concluded that the deputy could not be held liable under the circumstances presented because existing law did not clearly establish that her actions violated the Constitution.
For personal injury and wrongful death attorneys, Moller serves as an important reminder that cases involving law enforcement and public entities require more than proving a tragic outcome. They often turn on complex questions involving government immunity, legal custody, and whether a public employee’s actions actually created or increased the danger that caused the injury.
Understanding those distinctions is critical when evaluating whether a claim against a public entity is legally viable.
