Facing Sexual Assault Charges in San Antonio? What Texas Law Actually Requires the State to Prove.

A sexual assault charge in Texas is among the most serious criminal allegations a person can face. The consequences of a conviction extend far beyond prison time — they include mandatory sex offender registration under the Texas Sex Offender Registration Program, which in many cases is a lifetime requirement. Registration affects where you can live, where you can work, and how your name and photograph appear in publicly searchable databases accessible to anyone with internet access.

Because of these consequences, and because sexual assault allegations frequently arise from situations involving disputed facts, complex relationship dynamics, and evidence that is far less definitive than it initially appears, the defense of these charges demands immediate, experienced, and methodical legal representation. This post explains what the state must actually prove to convict, how these cases are typically investigated and prosecuted in Bexar County, and what effective defense looks like from the moment charges are filed.

What Texas Law Requires the State to Prove

Under Texas Penal Code Section 22.011, a person commits sexual assault when they intentionally or knowingly cause the penetration of the anus or sexual organ of another person without that person’s consent, cause the penetration of the mouth of another person without consent, or cause the sexual organ of another person to contact or penetrate the mouth, anus, or sexual organ of another person without that person’s consent.

The statute defines specific circumstances under which contact is considered to occur without consent — including when the victim is physically incapacitated, when the perpetrator uses physical force or coercion, when the victim is unconscious, when the victim has a mental disease or defect that prevents consent, or when the perpetrator is a public servant exploiting their official capacity. The state must prove each element of the charge beyond a reasonable doubt. That burden does not shift — it remains on the prosecution throughout the trial.

A first-offense sexual assault in Texas is a second-degree felony, carrying two to twenty years in the Texas Department of Criminal Justice and a fine of up to $10,000. When aggravating factors are present — including use of a deadly weapon, serious bodily injury, or when the victim is a child — the charge is elevated to aggravated sexual assault, a first-degree felony carrying five to 99 years or life in prison.

How Sexual Assault Cases Are Investigated in Bexar County

Sexual assault cases in San Antonio are typically investigated by the San Antonio Police Department’s Special Victims Unit, which focuses exclusively on sex crimes and child abuse cases. Investigators in this unit are trained in forensic interviewing techniques and work in coordination with the Bexar County District Attorney’s Sex Crimes Unit, which prosecutes these cases in the criminal district courts.

The investigation typically begins with a complainant’s statement, which may be followed by a sexual assault forensic examination — commonly referred to as a rape kit — conducted at a medical facility. The forensic examination collects biological evidence that is submitted to the Texas Department of Public Safety crime laboratory for DNA analysis. Investigators also review text messages, social media communications, surveillance footage, and digital records, and interview witnesses identified by both the complainant and the defendant.

One of the most significant aspects of sexual assault investigations that defendants often do not understand is how quickly the evidentiary record is built. Investigators are gathering statements, collecting digital evidence, and documenting the complainant’s account in the hours immediately following the report. The defense must begin its own investigation at the same pace — which is one of the primary reasons why retaining an attorney before making any statement to investigators is critical.

The Role of Consent and Credibility in These Cases

Many sexual assault cases prosecuted in Bexar County involve situations where the physical contact between the parties is not disputed — what is disputed is whether that contact was consensual. These cases turn entirely on credibility: the complainant’s account versus the defendant’s account, evaluated by a jury in the context of all available corroborating or contradicting evidence.

Text messages and social media communications between the parties before and after the alleged assault are frequently among the most significant evidence in these cases. Prior communications that establish the nature of the relationship, the context of the encounter, or the complainant’s statements to others in the immediate aftermath can either support or fundamentally undermine the prosecution’s narrative. Defense counsel must obtain and analyze this digital evidence through discovery and, where necessary, through independent investigation — before the prosecution has the opportunity to build its case around a selective presentation of the record.

False and mistaken allegations occur in sexual assault cases for reasons that range from genuine misunderstanding of what happened to deliberate fabrication motivated by relationship conflict, custody disputes, or other personal circumstances. Investigating the complainant’s history, motivations, and the consistency of their account across multiple statements — to law enforcement, to friends, to family, and in any written communications — is a standard and essential component of an effective defense.

Why the Decision to Speak to Investigators Is the Most Important One You Will Make

In any serious criminal investigation, the most common mistake a defendant makes is speaking to law enforcement before consulting with an attorney. This is particularly true in sexual assault cases, where investigators are trained to conduct extended interviews designed to elicit admissions, inconsistencies, and statements that can be used as evidence at trial. An investigator who tells you that your cooperation will help resolve the matter quickly is doing their job — which is to gather evidence for a prosecution.

You have the right to remain silent and the right to have an attorney present before and during any questioning. Invoking those rights clearly and immediately — “I am invoking my right to remain silent and my right to counsel” — and then saying nothing further until an attorney is present is the most protective action you can take in the early hours of an investigation. Statements made to investigators before an attorney is involved cannot be taken back, and they become part of the permanent evidentiary record of your case.

What to Look for in a Sexual Assault Defense Attorney

Sexual assault cases require an attorney with specific trial experience in sex crimes cases, familiarity with DNA evidence and forensic testimony, experience cross-examining SVU investigators and medical professionals, and the ability to handle the unique evidentiary and procedural issues these cases present. Board certification in criminal law from the Texas Board of Legal Specialization is the most verifiable indicator of demonstrated criminal trial experience. Prior experience as a prosecutor — particularly in a district attorney’s office that handled sex crimes cases — provides direct insight into how these cases are built and where they are vulnerable.
