The Tony Timpa case is the seven-year legal aftermath of a 32-year-old Dallas man’s death in police custody on August 10, 2016, after he called 911 for help during a mental health crisis and was pinned face-down by officers for roughly 14 minutes. Criminal charges against the officers were dismissed in 2019. A federal jury in September 2023 found that three officers violated Timpa’s constitutional rights but held only one of them personally liable, awarding $1 million to Timpa’s teenage son.
What Happened in the Dallas Parking Lot
Tony Timpa called 911 himself. He told the dispatcher he was scared, that he had been diagnosed with schizophrenia and depression, that he had not taken his prescription medication, and that he had used drugs. A private security guard handcuffed him before police arrived. He was unarmed.
When Dallas officers got there, they forced Timpa into a prone position. Officer Dustin Dillard pressed his knee into Timpa’s back and kept it there for about 14 minutes. Body camera footage captured Timpa pleading with the officers and at one point crying out, “You’re gonna kill me.” As he struggled to breathe, officers joked and mocked him. One said sarcastically, “I hope I don’t have to go to the hospital.”
Timpa eventually stopped moving. Officers appeared to assume he had fallen asleep. One of them said, “It’s time for school. Wake up!” Only after realizing he was not breathing did they attempt CPR. It was too late. The Dallas County Medical Examiner ruled the death a homicide, finding the cause was “sudden cardiac death due to the toxic effects of cocaine and physiologic stress associated with physical restraint.”1Justia. Timpa v. Dillard, No. 20-10876 (5th Cir. 2021)
Why the Restraint Killed Him
Positional asphyxia occurs when a person’s body position keeps them from breathing. When someone is held face-down with weight on their back, the diaphragm cannot expand enough to draw air. The National Institute of Justice has described the cycle: the person struggles because they cannot breathe, the officer applies more pressure to control the struggling, and breathing becomes more restricted still.2Office of Justice Programs / National Institute of Justice. Positional Asphyxia—Sudden Death
Stimulant drugs raise the risk. The combination of drug intoxication, physical exertion, and restraint can compound into cardiac arrest even in people with no underlying heart disease. Federal law enforcement guidance had said for decades before 2016 that officers should get a handcuffed person off their stomach quickly and never apply sustained weight to a prone subject’s back.2Office of Justice Programs / National Institute of Justice. Positional Asphyxia—Sudden Death The officers restraining Timpa did the opposite.
Three Years Before the Public Saw the Video
The body camera recordings were not released until August 2019, nearly three years after Timpa died. The Dallas Morning News and NBC5 fought a protracted legal battle against the city for access. A federal judge ordered the release, ruling that “the public has a compelling interest in understanding what truly took place during a fatal exchange between a citizen and law enforcement.”
The footage showed officers laughing over an unresponsive man, then scrambling once they realized he was dead. For three years, the public narrative had rested on official accounts. The video told a different story.
The Criminal Charges That Went Nowhere
A Dallas County grand jury indicted three of the officers in 2017: Dustin Dillard, Kevin Mansell, and Danny Vasquez. The charge was misdemeanor deadly conduct, a Class A misdemeanor under Texas law that covers recklessly placing another person in imminent danger of serious bodily injury.3State of Texas. Texas Penal Code Title 5 Chapter 22 – Section 22.05
The case never reached trial. In 2019, Dallas County District Attorney John Creuzot dismissed all three indictments, saying prosecutors did not believe they could prove the case beyond a reasonable doubt. The dismissal followed a lengthy investigation into the cause of death involving three medical examiners, including one hired by the Timpa family. The officers returned to active duty. The misdemeanor was the most serious charge prosecutors pursued, and they walked away from even that.
The Federal Lawsuit and the Qualified Immunity Fight
With criminal prosecution off the table, Timpa’s family sued in federal court under 42 U.S.C. § 1983, the statute that lets people sue government officials who violate their constitutional rights while acting in an official capacity.4Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights The suit named the City of Dallas and five officers. The core claim was that Dillard used excessive force in violation of the Fourth Amendment by keeping bodyweight pressure on Timpa long after he was subdued. Officers Mansell, Vasquez, Dominguez, and Rivera were accused of failing to intervene.1Justia. Timpa v. Dillard, No. 20-10876 (5th Cir. 2021)
Qualified immunity nearly ended the case at the door. The doctrine shields government officials from personal liability unless their conduct violated a constitutional right that was “clearly established” at the time. In July 2020, U.S. District Judge David C. Godbey granted the officers immunity and dismissed the lawsuit, ruling that no prior case with a sufficiently similar fact pattern had put the officers on notice.
The Fifth Circuit reversed on December 15, 2021. A three-judge panel held that “the state of the law in August 2016 clearly established that an officer engages in an objectively unreasonable application of force by continuing to kneel on the back of an individual who has been subdued.” The panel reinstated the excessive force claim against Dillard and the bystander liability claims against Mansell, Vasquez, and Dominguez. Only Officer Rivera’s dismissal stood.1Justia. Timpa v. Dillard, No. 20-10876 (5th Cir. 2021)
The City of Dallas asked the U.S. Supreme Court to intervene. On May 31, 2022, the Court denied certiorari, leaving the Fifth Circuit’s decision in place and sending the case to a jury.
What the Jury Decided in 2023
The trial took place in Dallas federal court in September 2023, more than seven years after Timpa’s death. His family’s attorneys asked the jury for roughly $300 million in total damages spread across family members.
The verdict was smaller and stranger. Jurors found that three of the four remaining officers, Dillard, Vasquez, and Dominguez, violated Timpa’s constitutional rights. Sergeant Mansell was not found to have violated his rights. But the jury also granted qualified immunity to Dillard, the officer whose knee had been on Timpa’s back, along with one additional officer. That left only Officer Raymond Dominguez personally liable.
The award was $1 million, given entirely to Timpa’s 15-year-old son. His mother and his estate received nothing. The family’s attorney called several parts of the outcome puzzling, pointing to the irony that Dillard received immunity from the jury while a bystander officer did not.
The split shows how qualified immunity works at trial. A jury can find that an officer’s actions were unconstitutional and still shield that officer from paying damages, because the “clearly established” test operates separately from the finding of a violation. The constitutional finding stands in the legal record. The financial consequence does not follow automatically.
What Changed in Dallas
The Dallas Police Department’s General Orders, revised in November 2024, explicitly prohibit the hog-tie method of restraint, which positions a person face-down with hands and feet bound behind the back. The written policy states that this method “places the prisoner in a physical position that restricts breathing capability and subjects the subject at risk for positional asphyxia.”5Dallas Police Department. General Orders
The city also built a crisis response program aimed at calls like the one Timpa made. RIGHT Care pairs a police officer with a paramedic, a licensed social worker, and a behavioral health clinician. As of 2025, 18 teams operate around the clock, seven days a week, with the goal of diverting people in psychiatric emergencies away from arrest and toward treatment.6Dallas City Hall. R.I.G.H.T.
