The death penalty in Texas applies to a narrow set of the most serious killings, decided in two stages: a jury first convicts the defendant of capital murder, then answers specific sentencing questions that determine whether the sentence is death by lethal injection or life in prison without parole. Texas has carried out more executions than any other state since capital punishment resumed nationally in 1976, with 591 executions through the end of 2024. Here is what actually has to happen for someone to be sentenced to death in Texas and eventually executed.
What Counts as Capital Murder
An intentional killing is not enough on its own. Texas Penal Code Section 19.03 lists ten specific circumstances that turn a murder into a capital felony, and prosecutors have to prove at least one of them beyond a reasonable doubt.1State of Texas. Texas Code Penal 19.03 – Capital Murder
- Killing a peace officer or firefighter who was on duty, when the defendant knew the victim’s role.
- Murder committed during a kidnapping, burglary, robbery, aggravated sexual assault, arson, obstruction or retaliation, or certain terroristic threats.
- Murder for hire — both the person who kills and the person who pays.
- Murder while escaping a prison or jail.
- Murder by an inmate of a prison employee, or a killing done to advance a criminal organization.
- Murder by someone already serving a sentence for capital murder, murder, aggravated kidnapping, aggravated sexual assault, or aggravated robbery.
- Killing more than one person in a single event or in separate events that were part of the same plan.
- Murder of a child under ten.
- Murder of a child between ten and fourteen.
- Murder of a judge or justice, at any court level, in retaliation for or related to their service.
Texas capital murder always requires a death. The U.S. Supreme Court held in Kennedy v. Louisiana (2008) that the death penalty cannot be imposed for crimes against a person that do not result in death, which closes off any expansion into non-homicide offenses.2Justia. Kennedy v. Louisiana, 554 U.S. 407 (2008)
Who Cannot Be Executed
Even after a capital murder conviction, federal constitutional rulings take certain defendants off the table entirely.
Anyone who was under 18 at the time of the offense cannot be executed. The Supreme Court set that line in Roper v. Simmons (2005), and age is measured at the time of the crime, not the trial.3Justia. Roper v. Simmons, 543 U.S. 551 (2005)
People with intellectual disability cannot be executed either. Atkins v. Virginia (2002) established that rule.4Justia. Atkins v. Virginia, 536 U.S. 304 (2002) Two later decisions tightened how Texas has to make that determination: Hall v. Florida (2014) rejected rigid IQ cutoffs and required courts to account for testing margins of error, and Moore v. Texas (2017) struck down a set of informal, unscientific factors Texas courts had been using — including whether the defendant could lie effectively.
A prisoner who has become incompetent — meaning they cannot understand that they are about to be executed or why — cannot be put to death while in that condition. That was Ford v. Wainwright (1986),5Justia. Ford v. Wainwright, 477 U.S. 399 (1986) later refined in Panetti v. Quarterman (2007), which held that a delusional understanding of the reason for execution can fall short of the required awareness.
How the Jury Decides Life or Death
A capital conviction does not automatically produce a death sentence. Texas uses a separate sentencing phase governed by Article 37.071 of the Code of Criminal Procedure. The same jury hears additional evidence and then answers a series of specific questions called special issues.6State of Texas. Texas Code of Criminal Procedure Art. 37.071 – Procedure in Capital Case
The first question is future dangerousness: is there a probability that the defendant would commit criminal acts of violence in the future that would constitute a continuing threat to society? The state must prove this beyond a reasonable doubt, and all twelve jurors must agree. One “no” vote produces a life sentence without parole.
If the defendant was convicted under Texas’s law of parties — that is, they participated in the crime but may not have personally killed the victim — the jury faces a second question. It must find that the defendant actually caused the death, intended to kill, or anticipated that a life would be taken. Again, unanimity is required.
Finally, the jury considers mitigation. Taking into account the defendant’s character, background, and personal moral responsibility, is there sufficient mitigating evidence to warrant life instead of death? The defense uses this stage to present things like childhood trauma, mental illness, cooperation with law enforcement, or remorse. To answer “no” on mitigation — which is the answer that allows a death sentence — the jury must be unanimous. If ten or more jurors find sufficient mitigation, the sentence is life without parole.
The math favors life. Prosecutors need twelve jurors at every step; the defense needs only one holdout at any stage to block a death sentence.
Appeals After a Death Sentence
A death sentence sets off a review process that typically lasts more than a decade. It runs through three main layers.
Direct Appeal
Every death sentence gets an automatic direct appeal straight to the Texas Court of Criminal Appeals, the state’s highest court for criminal matters. Capital cases skip the intermediate appellate courts that hear other felonies.7Texas Attorney General. Capital Punishment Appellate Guidebook This stage looks at the trial record for legal error, sufficiency of the evidence, and compliance with state and federal constitutional requirements.
State Habeas Corpus
Alongside the direct appeal, the defense files a state habeas corpus application under Article 11.071. This is where claims that go beyond the trial record are raised: newly discovered evidence, ineffective assistance of counsel, prosecutorial misconduct that came to light later, or other constitutional problems the trial court could not have addressed. The application must be filed in the convicting court within 180 days after habeas counsel is appointed, with extensions available for good cause.8State of Texas. Texas Code of Criminal Procedure Art. 11.071 – Habeas Corpus Procedure in Death Penalty Case Miss that deadline and any available claims can be permanently waived.
Federal Habeas Review
Once state courts have denied relief, the defense can move to federal court. A federal district court reviews whether the state proceedings violated the U.S. Constitution or federal law, with appeal to the U.S. Court of Appeals for the Fifth Circuit and, rarely, the U.S. Supreme Court. Federal review is narrow. Courts generally defer to state findings unless the state court’s decision was unreasonable in light of clearly established federal law. Even so, this stage has produced reversals in Texas cases, especially on ineffective-counsel and suppressed-evidence claims.
Clemency and the Governor’s Limited Power
The Texas governor has less power to stop an execution than many people assume. Under Article IV, Section 11 of the Texas Constitution, the governor cannot commute a death sentence to life imprisonment without a prior written recommendation from a majority of the Texas Board of Pardons and Paroles.9Justia Law. Texas Constitution Art. 4 – Sec. 11
The one thing the governor can do alone is grant a single reprieve of up to 30 days, and only once per case.10Texas Department of Criminal Justice. Executive Clemency The Board of Pardons and Paroles rarely recommends clemency, does not hold public hearings on capital clemency applications, and votes individually rather than convening as a group. In practice, a governor who wanted to stop an execution would usually have no legal way to do more than delay it briefly.
The Execution
Once appeals and clemency options are exhausted, the convicting court issues an execution warrant setting a date at least 91 days out.11State of Texas. Texas Code of Criminal Procedure Art. 43.141 Executions are carried out by lethal injection using a lethal dose of pentobarbital, a powerful sedative. All executions take place at the Huntsville Unit — commonly called the Walls Unit — which houses the state’s execution chamber.
On the scheduled day, the condemned person is moved to the chamber and given a chance to make a final statement, which prison staff record. The offender may designate up to five witnesses from an approved visitation list, including family members and a spiritual advisor. The victim’s family may also attend, along with up to five media representatives split between the two witness rooms.12Texas Department of Criminal Justice. Victim Services Division – Viewing Executions The procedure is supervised by the director of the state’s correctional institutions division. After the drug is administered and the heart stops, death is pronounced.
