Criminal defense in Harris, Montgomery, Fort Bend, Galveston, and Brazoria Counties. Explore Counties & Courts →
Every case we take on gets filed, studied, and fought the same way, with a strategy built for the specific charge you are facing.
Discuss Your CaseHomicide, aggravated assault, and deadly weapon charges. Sam has tried first degree felony cases to a jury verdict, including the Barajas acquittal in Brazoria County.
Houston assault lawyerDomestic assault, aggravated domestic assault, protective order allegations, and repeat offense filings. These cases are emotionally difficult for everyone involved and move quickly at the bond stage.
Houston family violence lawyerFirst offense through felony DWI, plus the ALR license hearing that runs on its own clock. That hearing has a short deadline and is separate from the criminal case.
Houston DWI lawyerPossession, possession with intent to deliver, and trafficking, from misdemeanor amounts to major felony penalty groups. Where the search happened is often the case.
Houston drug possession lawyerRobbery, burglary, and theft at both misdemeanor and felony levels. Value thresholds, intent, and restitution are all far more negotiable early than after the case is set.
Houston theft lawyerAn injury and a criminal case often arise from the same incident. Sam also represents injured people and families in Houston personal injury and wrongful death claims. See every charge on the practice areas index.
A criminal case is heard where it was filed, not where you live. That is why the county matters more than the city: the prosecutors, the bond practice, and the diversion programs are different in each one.

Houston Criminal Defense FAQ
Criminal charges raise immediate questions about what to do, when to contact a lawyer, what representation may cost, and what happens next. These answers provide general information about working with Your Houston Criminal Lawyers and the criminal-defense process in Houston and surrounding Texas courts.
Take the accusation seriously and be careful about what you say. Do not lie, destroy evidence, contact witnesses in an attempt to influence them, or discuss the facts of the case on social media. If police want to question you about a criminal matter, you can ask to speak with an attorney before answering questions about the allegations.
Follow any bond conditions, protective orders, no-contact requirements, or court orders that apply to you. Preserve documents, messages, photographs, videos, names of witnesses, and other information that may be relevant to the case. Contacting a criminal defense attorney early gives the lawyer more time to evaluate the allegations and available evidence.
You should consider contacting a criminal defense attorney as soon as you learn that you are under investigation, have been arrested, receive a court date, discover that a warrant may exist, or believe criminal charges could be filed.
A lawyer may be able to evaluate the situation before important interviews, court settings, evidence issues, or deadlines occur. You do not necessarily have to wait until a case reaches trial — many important decisions happen much earlier in the criminal process.
Your Houston Criminal Lawyers represents people facing misdemeanor and felony criminal charges, including murder and capital murder, assault, family violence and domestic assault, DWI and DUI, drug and narcotics offenses, robbery, burglary, theft, juvenile matters, and other serious criminal cases.
Visit the Criminal Defense Practice Areas page to find the section that matches the charge or allegation you are facing.
The firm represents clients in Houston and criminal courts throughout the Greater Houston area, including matters filed in Harris, Montgomery, Fort Bend, Galveston, and Brazoria Counties, as well as other nearby jurisdictions when appropriate.
The county of filing matters because the courthouse, prosecutors, procedures, available programs, bond practices, and local court procedures can differ by jurisdiction. Visit Counties & Courts We Serve for courthouse and location information.
There is no single standard fee for a criminal defense case. The cost can depend on the charge, complexity of the evidence, stage of the case, expected court work, whether experts or investigators are needed, and whether the matter proceeds toward a jury trial.
Your Houston Criminal Lawyers offers a free initial consultation, so there is no charge simply to contact the firm initially and discuss what you are facing. If representation is offered, the fee arrangement should be explained before you decide whether to hire the firm.
“Criminal lawyer” is a broad term for a lawyer who practices criminal law, while a criminal defense attorney represents people accused of or investigated for crimes.
Prosecutors also practice criminal law, but they represent the government. Criminal defense lawyers represent the accused. Sam R. Cammack III has experience on both sides: he previously served as a felony prosecutor and now represents people facing criminal charges.
Look at the lawyer's criminal-defense experience, relevant jury-trial experience, familiarity with the type of charge, who will actually handle the case, communication practices, and how fees are explained. For a serious felony, experience handling serious felony cases is particularly relevant.
Be cautious about anyone who guarantees a particular result before fully reviewing the evidence. You can also verify a Texas lawyer's licensing history and professional record through the State Bar of Texas. Learn more about Sam R. Cammack III's background and review selected case results.

Before focusing on criminal defense, Sam served as a felony prosecutor in Harrison County, Texas. That experience gave him firsthand exposure to how prosecutors evaluate evidence, prepare witnesses, develop criminal cases, and present felony prosecutions.
In defense practice, that background can help him examine the prosecution's theory from both perspectives, identify evidentiary issues, prepare the defense, evaluate negotiations, and prepare serious cases for trial when necessary. Read Sam Cammack's biography.
No. Criminal cases can end in many different ways depending on the charge, evidence, jurisdiction, procedural history, available legal issues, and decisions made by the client after receiving legal advice.
Depending on the circumstances, a case may involve dismissal, a grand-jury no-bill, reduction of charges, negotiated resolution, diversion or other pretrial disposition where available, mistrial, acquittal, or conviction after trial. The appropriate strategy depends on the individual case.
Yes. The firm's Case Results page documents selected dismissals, no-bills, jury-trial outcomes, and serious felony matters, including independently reported cases.
