Texas Murder Trial Defense Knowledge Hub

Start here after a murder accusation

A murder arrest can leave a family working with scraps of information. Someone has called from jail. There is a hearing date, perhaps a copy of the charge, and a great deal nobody has explained. Start with the part of this guide that answers your immediate question.

This is the murder-defense hub for Heath Hyde, P.C. The six subject areas cover the charge itself, possible defenses, the evidence, investigation, trial, and help for families. The pillar guide and the shorter blog articles will have links here when they are published. You won’t need to search the blog for each installment.

Some work cannot wait for a trial date. Think of a shop’s security video that records over yesterday’s footage, or a message on a phone that someone is about to replace. Tell the lawyer where that information may be. Keep what you already have. Editing a photograph or deleting an embarrassing message can make matters worse.

Bring the paperwork, even if you aren’t sure which document is important. Bond conditions, notices of a hearing, and a police property receipt can all help the lawyer work out what has happened. For locating someone in custody and dealing with booking or bond, start with the Texas Family Arrest Guide. Here, the focus is the homicide allegation.

About Heath Hyde

Heath Hyde is a former Dallas County prosecutor with experience in more than 400 state and federal jury trials and more than 100 murder cases. His Texas State Bar number is 00796807. The firm is based in Sulphur Springs and represents clients in East Texas and statewide. Heath Hyde’s biography explains his background.

The material here draws on Heath Hyde’s Texas murder-defense pillar article. It is general information for people facing a homicide investigation and for families trying to understand the case. An attorney must review the actual evidence and governing law before advising someone about a particular charge.

Charges, elements and punishment

Look at the indictment before trying to work out a defense. "Murder" on a jail website tells you much less than the charging language does. What act is alleged? Who is said to have done it? Which mental state must the prosecutor prove? Those questions can lead to quite different investigations.

Murder under Section 19.02

Section 19.02 contains several routes to a murder charge:

• An intentional or knowing killing.
• An intent to cause serious bodily injury, coupled with an act clearly dangerous to human life that causes death.
• Felony murder: an act clearly dangerous to human life causes death in connection with the felony conduct specified by Section 19.02(b)(3), including immediate flight. The underlying felony cannot be manslaughter.
• Specified deaths involving unlawfully manufactured or delivered fentanyl-related controlled substances.

Counsel should identify the alleged route from the charging papers before assessing the evidence.

For that reason, "I didn’t mean for anyone to die" does not answer every murder charge. The lawyer has to read the theory alleged and then check its parts against the evidence. In a felony-murder case, that includes the underlying felony, the dangerous act, and the connection to the death.

Capital murder and other homicide charges

Capital murder is a separate statutory offense. Section 19.03 requires the specified kind of murder and an additional circumstance. Murder during robbery is one example; murder for payment is another. The details of the category matter. So does the State’s decision about seeking the death penalty, which brings its own procedures and preparation demands.

Recklessness is the mental state for manslaughter. Criminal negligence is the mental state for criminally negligent homicide. These words have legal meanings, not just their everyday meanings. If a gun went off unexpectedly, calling the event an accident is the beginning of a factual inquiry, not the end of the legal one. Chapter 49 separately addresses intoxication manslaughter.

Sentencing, sudden passion and parole

For most murder convictions, first-degree felony punishment applies. Here is what a sudden-passion finding changes under Section 19.02(d):

• Issue: sudden passion arising from an adequate cause.
• Who must prove it: the defendant.
• Burden: a preponderance of the evidence.
• Effect if proved: second-degree felony punishment for the murder conviction.

This takes place at punishment. Self-defense asks a different question about whether the conduct was justified.

Bring the criminal-history questions into the sentencing discussion. An enhancement allegation or deadly-weapon finding may change what the family needs to understand. If someone predicts a release date, ask what that prediction is based on. Becoming eligible for parole is not the same as being granted it.

Defenses and disputed liability

Guilt must be proved beyond a reasonable doubt. The defense investigation tests the State’s account against the charge and the available evidence.

Intent, causation and the law of parties

How does a prosecutor prove what was in someone’s mind? Usually by asking the jury to draw conclusions from the person’s actions and the surrounding events. That might involve the weapon used, an injury, or a statement. Take a text message, for example. Before deciding what it means, read the exchange it came from. Who was speaking, what were they responding to, and what came next?

Then there is causation. If several people inflicted injuries, or toxicology shows more than one substance, an expert may need to examine how the death occurred. A medical condition or intervening event may also need investigation. An official conclusion in a report is something to check against the underlying material, not a substitute for that material.

"He wasn’t the person who caused the injury" is an important fact to tell counsel, but it may not dispose of the accusation. Under Sections 7.01 and 7.02, the State can allege responsibility for another person’s conduct. What does it say your loved one did to assist? Does it allege an agreement? The proof has to meet the relevant statutory requirements. Being there or knowing the people involved is not enough by itself.

Self-defense and defense of another person

These provisions in Penal Code Chapter 9 address different uses of force:

• Section 9.31: force in self-defense.
• Section 9.32: deadly force in self-defense.
• Section 9.33: force or deadly force to protect another person.

Discuss the encounter in order with counsel: what the accused saw or heard, any known threats, the response and why it appeared immediately necessary. Injury photographs and recordings may help. Apply Chapter 9’s conditions and restrictions to those facts, including the accused’s reasonable belief at the time.

Other issues to investigate

Other questions for the defense file include:

• Alibi: which people or records can place the accused elsewhere?
• Identification: what did the witness see, and how did police obtain an identification?
• Accomplice testimony: what corroboration does the law require?
• Mental health: is the concern competency to proceed, a possible insanity defense or evidence for punishment?

Those mental-health questions have different legal standards. Give counsel the available history and records without assuming a diagnosis answers all of them.

Evidence and forensic science

A second analyst may need the worksheets and testing data before giving an opinion about a lab report. Ask what is still missing from the file. The disagreement, if there is one, could concern the conclusion drawn from a result rather than the accuracy of the test itself. Until the reviewing expert has the necessary material, there may be no responsible way to tell which issue is involved.

Medical records, DNA and firearms

An autopsy review may require the complete file. Besides the report, that can mean photographs, diagrams, notes, toxicology data, and retained specimens. Tell the reviewing pathologist what is disputed. Whether injuries occurred in a particular order is a different question from whether a medical condition contributed to the death, and may require different material.

DNA can identify a possible source of biological material without telling us when it was deposited or how it got there. Mixtures and transfer may need specialist review. Firearms comparisons have their own records and limitations. Counsel should obtain the comparison material and documentation, not just a sentence describing the result. A bloodstain reconstruction also needs to be checked against the scene and the assumptions behind it.

Phones, location records and video

A dot on a map looks precise. Ask where it came from. Cell-site records are not the same as precise location data from a device, and the analyst’s method matters. Compare the map with the records used to make it.

For a digital-evidence review, preserve more than the image someone forwarded:

• Messages: the surrounding conversation and any attachments.
• Video: the native file, available metadata and information about the camera system.
• A timeline built from several devices: clock settings, time zones and missing intervals.
• Phone-location exhibits: the provider or device records and the analyst’s method.

A six-minute difference between two camera clocks can change the order a viewer thinks events occurred in. It is worth resolving that before relying on the timeline.

Witnesses and evidence handling

An identification review starts with the account given closest to the event. Work outward from there:

• Original description — the details supplied before later photographs or news coverage.
• Viewing conditions — how far away the witness stood, available light, anything blocking the view and how long it lasted.
• The procedure: how investigators presented photographs or arranged an identification.
• Later changes: details added, removed or contradicted in subsequent interviews.
• Any benefit offered: what the witness was promised, if anything.

For a collected item, the property records ought to explain its trip to the laboratory. Start with the collector’s label, then compare the transfers and laboratory receipt. If they don’t line up, find out why. It may turn out that an entry was omitted, or there may be a substantive question about the sample. Counsel needs that answer before assessing whether to challenge admission of the item or the weight the jury should give it.

Investigation, statements and discovery

Police may be investigating long before an arrest. They may ask to speak with somebody as a witness while still considering that person’s role. Before an interview about a death, get legal advice specific to the situation. Your lawyer can speak with investigators about what they want.

Preserve first, review with counsel

What to give counsel about a possible source of evidence:

• Where to look — an address, business name or location of a camera.
• Who may have it — a witness, account holder or records custodian, if known.
• When it matters — the approximate time of the event and any reason the material may soon disappear.
• What you already have — keep original messages, photographs and devices unchanged.

For witnesses, give the defense team names and a description of what each person may know. Don’t arrange a meeting for them to compare their accounts.

Ordinary jail calls and messages may be recorded. A family conversation about what happened can therefore become part of the case. Save that discussion for the confidential channel your lawyer explains to you. Having a relative help with the case does not, by itself, make every conversation with that relative privileged.

Searches and recorded statements

Save the papers left after a search. Counsel will need the warrant and supporting affidavit, the return listing what was seized, and records showing what investigators actually examined. A phone extraction can require a specialist’s help. For a police interview, the review can include the full recording, warning forms, translation records and relevant medical information as material to review. A signed form alone won’t describe everything that happened in the room. Custody, warnings, a request for counsel and voluntariness all need attention.

Counsel can assess whether a defect supports a motion to exclude evidence. That takes more than pointing out something troubling in a report: the motion has to fit the law and the record, and the court must rule on it.

Discovery and missing material

Article 39.14 is the Texas criminal discovery statute. Its disclosure requirements include exculpatory, impeachment and mitigating material. In plain terms, that can include information useful to the accused on guilt, witness credibility or punishment. It also restricts dissemination. Get counsel’s instructions before sharing a document or recording with anyone outside the permitted review process.

Use the reports to check the production. If an officer describes a recording, can the defense locate and play that recording? If the laboratory sent a supplement, is the supplement included? Keep a record of those requests and the responses. A folder can hold thousands of pages and still be missing the one item the expert needs.

Trial preparation, sentencing and review

Preparing for trial and considering a negotiated resolution can happen at the same time. The client needs an assessment of the evidence, possible defenses, and punishment exposure to evaluate either choice. The number of years in an offer is only part of that discussion.

Investigators and experts

An expert needs a specific assignment. Was a wound consistent with the account in the report? Could a toxicology finding affect the medical conclusion? Is the location map supported by the phone records? Those questions may need three different specialists. Before authorizing additional testing, counsel should find out how much sample remains and whether the proposed test will consume it. There may be no second opportunity to test that material.

An investigator may check the scene, interview witnesses, or collect records for a timeline. The work needs to include facts that don’t fit the preferred account. Learning about a difficult fact early gives counsel time to investigate it. Learning about it from a witness at trial leaves far fewer options.

Jury selection and instructions

During jury selection, counsel needs to explore whether the prospective jurors can apply the law to this case, including the burden of proof and any supported defense. The written instructions come later and tell the jury what it must decide. Counsel has to work from the trial evidence when requesting an instruction on a defense or a lesser offense; the request cannot rest on the charge’s name alone.

A timeline or demonstration should help explain the record. It should not turn an uncertain time into an exact one or suggest a fact no witness or record supports. Cross-examination of an expert may be about a particular assumption or missing piece of data, rather than a general attack on the person’s qualifications.

Punishment and the record after trial

If punishment becomes an issue, records of health, treatment, education, work, and family history may be relevant. It takes time to collect and assess them. Waiting for a verdict to begin that work can leave counsel without material that was available earlier. Capital cases require attention to their additional procedures and preparation needs.

After a conviction, ask promptly about deadlines. Direct appeal and post-conviction habeas review are different procedures with different requirements and available issues. Trial objections, requested instructions, and rulings can affect what a reviewing court has before it. Don’t assume there is extra time while the family looks into its options.

Family questions and choosing a lawyer

You don’t have to assemble a perfect file before calling. Bring the papers you were given, even if you don’t know what some of them mean. The notice with a hearing date is especially useful. So is the receipt for property police took. On a separate sheet, put the questions you’ve been trying to get answered and where any other information came from. A rumor in a group chat should be identified as just that.

Agree on a family contact for updates and keep a question list. Leave witness interviews to the defense team.

Questions to ask before hiring counsel

Ask who will actually handle the case in court. "Murder cases handled" and "first-chair murder jury trials" describe different experience. Find out what role the lawyer performed, how that experience can be verified, and who else will work on this case. Discuss investigator and expert costs as well as the lawyer’s fee.

Communication is part of the decision. Who returns calls? How will the client hear about discovery and offers? How will the lawyer handle a large production of digital records? Ask about the court handling the charge, too. You should be able to understand the answers. A record of trial experience can inform the work, but it cannot guarantee a result.

The Texas homicide statutes apply across the state. The court calendar, investigating agencies, and available records in your case will depend on where it is being handled. When contacting the firm, use the county, court, and cause number on the paperwork. General court-process questions are covered in the East Texas Criminal Defense Knowledge Hub.

Questions families often ask

The supporting article series

The planned series contains 60 articles in six groups. Charges and punishment come first, followed by defenses, forensic evidence, investigations, trial and review, and family decisions. Each group above provides a starting explanation. As the individual blog articles are published, links will be added to the relevant section of this hub.

The pillar article will provide a separate, continuous guide to preparing a Texas murder defense. This page will remain the central place to find it and the supporting articles. Unpublished articles are not linked here.
