Why Choose Board-Certified Former Prosecutor Brad Thornton?

When fighting a homicide indictment, the qualifications of your trial attorney can mean the difference between freedom and a life sentence. Attorney Brad Thornton offers distinct trial advantages that few law firms in Texas can match:

  • Board Certified in Criminal Law: Less than 1% of practicing Texas attorneys earn Board Certification in Criminal Law from the Texas Board of Legal Specialization. This credential signifies master-level courtroom experience and proven legal competence.
  • Former Chief Prosecutor Advantage: Brad Thornton spent years prosecuting major felony offenses—from initial arrest and grand jury presentations to multi-week jury trials and appeals. He understands prosecution playbooks, forensic evidence vulnerabilities, and police procedure flaws from the inside.
  • Proven Track Record in High-Stakes Trials: With over 100 jury trials under his belt, Brad prepares every homicide case as if it will be decided by a jury, giving you maximum leverage during pre-trial negotiations and grand jury proceedings.

Understanding Homicide Offenses Under the Texas Penal Code

In Texas, “homicide” is an umbrella term covering four distinct statutory offenses under Chapter 19 of the Texas Penal Code. The exact charge filed by prosecutors depends entirely on the alleged mental state (intent, recklessness, or negligence) and specific aggravating circumstances.

Explore our detailed guides below for each specific category of homicide in San Antonio:

1. Capital Murder (TPC § 19.03)

The most severe offense under Texas law, Capital Murder involves intentionally causing death under specific statutory circumstances—such as killing a law enforcement officer, committing murder during a kidnapping or robbery, or causing multiple deaths. Punishable strictly by Life in Prison Without Parole or the Death Penalty.

2. Murder (TPC § 19.02)

Occurs when an individual intentionally or knowingly causes a death, intends to cause serious bodily injury resulting in death, or causes death while committing a felony (Felony Murder). Classified as a First-Degree Felony punishable by 5 to 99 years or Life in TDCJ prison.

3. Manslaughter (TPC § 19.04)

Unlike murder, manslaughter does not require proof of intent. Instead, it involves causing the death of another individual through reckless behavior—consciously disregarding a substantial and unjustifiable risk. Classified as a Second-Degree Felony punishable by 2 to 20 years in prison.

Learn more about Manslaughter Defense →

4. Criminally Negligent Homicide (TPC § 19.05)

Committed when a death results from criminal negligence—a gross deviation from the standard of care that a reasonable person would exercise, caused by an obliviousness to substantial risk. Classified as a State Jail Felony punishable by 180 days to 2 years incarceration.

Texas Homicide Statutory Punishment Matrix

Sentencing for homicide convictions in Texas varies significantly based on the degree of the offense and statutory enhancements:


Affirmative Defenses & Trial Strategies for Homicide Charges

Defending against a homicide accusation requires immediate tactical action. Attorney Brad Thornton conducts independent defense investigations, subpoenaing surveillance footage, analyzing ballistics and forensic biology, and challenging police interrogation techniques. Common statutory defenses in Texas include:

1. Self-Defense & “Stand Your Ground” (TPC § 9.31 & § 9.32)

Texas law explicitly recognizes your right to protect yourself or another person with deadly force if you reasonably believe it is immediately necessary to prevent another’s unlawful use of deadly force. Under Texas “Stand Your Ground” provisions, you have no duty to retreat if you are legally present and not engaged in criminal activity.

2. Defense of Others & Defense of Property (TPC § 9.33 & § 9.42)

Deadly force can be legally justified to prevent the imminent commission of violent felonies such as aggravated robbery, burglary, kidnapping, or sexual assault against yourself or innocent third parties.

3. Lack of Culpable Mental State or Accidental Death

Prosecution teams must prove intent or recklessness beyond a reasonable doubt. Demonstrating that an incident was a tragic accident without criminal recklessness or negligence can lead to grand jury “No-Bills,” reduced charges, or full acquittals.

4. Constitutional Suppression Motions

If law enforcement officers from the San Antonio Police Department (SAPD) or Bexar County Sheriff’s Office violated your 4th, 5th, or 6th Amendment rights—via unlawful searches, illegal arrest warrants, or unconstitutional questioning—we fight to suppress key evidence before trial.

It’s my pleasure to leave a little something here for Brad Thornton, and “Thornton Criminal Defense”. Unfortunately, I made a big mistake and got a DWI, a third or subsequent DWI. Mr. Thornton was able to help me out with this situation I was facing, serious prison time. I’m still really not sure how things worked out so well, other than this man does his job very well. I ended up with PROBATION, and the best possible outcome for my situation. 5 stars all the way! There is also a second part to this equation, her name is Rachel, Mr. Thornton’s paralegal. She was always on point the entire time, always there to answer my phone calls and to help keep me calm, this was a very stressful time for me. I truly can’t say thank you enough to the both of you, outstanding job y’all! I highly recommend, if you have a felony DWI and you just don’t know what to do? At least take the time and reach out to “Thornton Criminal Defense”, sit down with Brad and have a conversation about your future, he really might be able to help you out…

Brad Thornton handled my case with incredible professionalism and compassion. He took the time to understand my situation, explain every step clearly, and built a mitigation packet that convinced the DA to dismiss my case completely. Communication was prompt, honest, and realistic the whole way through. I never felt like ‘just another file’ on someone’s desk. I would 100% recommend him to anyone who needs a serious, detail-oriented attorney who actually fights to protect your future.

Most importantly to me, he treated my son with dignity and respect. I was pleased and impressed with the way the case was handled. I would recommend him to anyone!

We got the best possible outcome we could ask for. I'm glad we decided to go with Brad. He was the only attorney that called us back that night after calling several that day. He even called to check in on how things were going the following day. Great communication throughout the entire process. I highly recommend choosing Brad and his team.

Frequently Asked Questions About Texas Homicide Law

The core distinction lies in the defendant's mental state. Murder requires proof of intent or knowledge to cause death or serious bodily harm. Manslaughter requires proof of recklessness—acting with disregard for a known, substantial risk without intending to cause death.

Yes. Before a felony case goes to trial in San Antonio, prosecutors must present it to a Grand Jury. An experienced criminal defense attorney can prepare a compelling defense packet to present to the Grand Jury, advocating for a "No-Bill" (full dismissal of charges).

Under Texas Code of Criminal Procedure Art. 42A.054, judge-ordered community supervision (probation) is legally barred for murder and capital murder convictions. However, probation may be available under specific circumstances for lesser offenses like manslaughter or criminally negligent homicide if awarded by a jury.

Incurring a homicide investigation requires immediate invocation of your 5th Amendment right to remain silent. Do not answer questions or give statements to police detectives without a defense lawyer present. Contact a Board-Certified defense attorney immediately.
