Few criminal charges are as stigmatized or as emotionally charged as sex crime offenses. Although the U.S. justice system holds that individuals are innocent until proven guilty, many individuals charged with sex crimes find that this is not the way that they are treated, as those around them, and even family members and friends, may jump to conclusions based solely on the accusations made against them.

As such, anyone facing sex crime charges of any kind cannot afford to take chances with their defense. A sex crime conviction can not only bring with it extreme legal consequences, but those convicted also will be required to have their names listed in a national sex offender registry. This can affect job prospects, personal relationships, and even where a person can live for years to come. At the Law Offices of Mark T. Lassiter, we know how difficult it can be for anyone in Dallas to be facing sex crime charges and these potential penalties. However, with the help of an aggressive legal team, you might be able to get your charges reduced or even dismissed altogether.

Types of Sex Crimes

There are a number of different sex crimes charges that individuals may face, all of them extremely serious and requiring fast, effective legal attention. When facing the following charges, it is highly advised to seek the help of a qualified and capable defense team.

Sex Crimes According to Texas Law

Texas state laws and federal laws determine whether a specific action constitutes a sex crime. Typically, they are any type of action that involves pornography, sexual misconduct, or sexual assault.

Following are definitions of sex crimes under the Texas Penal code:

1. Sex crimes involving children

It’s illegal to participate in a sexual act with a person under the age of 18.

2. Sex crimes involving sexual assault

Statutes in Texas don’t include the word rape. They use the term “sexual assault” as a crime under state laws.

3. Sex crimes involving pornography

It’s illegal to hold, possess, own, create, store, or participate in pornography in any way.

4. Sex crimes involving prostitution

Defenses Against Sex Crime Allegations

If you find yourself facing allegations of a sex crime, there are various defenses you could use, depending on the circumstances surrounding your case. Some of the common defenses for sex crimes include:

  • The victim wrongfully identified the defendant;
  • The defendant wasn’t present during the alleged sex crime and has an alibi to confirm that; or
  • The defendant didn’t understand what they were doing because of psychological problems.

Affirmative Defense Against Sex Crimes

If you choose to use the affirmative defense strategy, that would mean you admit to committing the act but argue that the circumstances do not make it a criminal offense. With this defense, you’re not admitting that you’re guilty of committing a sex crime but attempting to show the court that the act wasn’t a crime. The specific circumstances that could justify using an affirmative defense include:

  • The defendant didn’t use threats, force, or cause the victim duress during the offense.
  • The defendant and victim were married at the time of the incident.
  • The victim gave consent to sexual contact.
  • The defendant wasn’t more than three years older than the victim if the case involves statutory rape.

Defenses Against Statutory Rape

Texas laws issue exemptions to the charge of statutory rape, which occurs when the victim is underage.

  • Marital Exemption: The adult defendant is married to the minor, which allows sexual acts with their spouse despite being under the legal age.
  • Romeo and Juliet Exemption: The victim who is a minor between the ages of 14 and 17, gave consent to the defendant, who isn’t more than three years older than the minor.
  • Mistaken Age: The defendant believed the victim was over the age of consent and couldn’t have known how old they were.

Additional Defenses Against Sex Crimes

If you’re facing charges of sexual assault, you could potentially use any of the defenses below:

  • The defendant’s intent was not to commit a sex crime.
  • The defendant didn’t possess the knowledge to commit a sex crime.
  • The sexual activity was actually medical care for a child, and excluded contact with or penetration of the child’s sexual organ, mouth, or anus.
  • The defendant was insane.
  • The victim was of legal age and provided consent to the defendant.

Penalties for Sex Crime Convictions

The penalty you face will depend on various circumstances of the sex crime charge against you, such as:

  • The age of the victim
  • Your age
  • The sexual act that occurred
  • Your relationship with the victim
  • Prior sex crime convictions

Examples of misdemeanor sexual offenses include:

  • Indecent exposure
  • Prostitution
  • Solicitation of prostitution
  • Harassment
  • Sexting by a minor

The penalties for misdemeanor sex crime convictions are:

  • Class A misdemeanor: A maximum of one year in jail and $4,000 in fines.
  • Class B misdemeanor: Up to 180 days in jail and a maximum of a $2,000 fine.
  • Class C misdemeanor: Up to $500 in fines.

Examples of felony sexual offenses include:

  • Sexual assault
  • Aggravated sexual assault
  • Indecency with a child
  • Sex trafficking
  • Indecent contact with a child
  • Possession of child pornography

The penalties for felony sex crime convictions are:

  • First-degree: Between 5 and 99 years or life in prison and a maximum of $10,000 in fines.
  • Second-degree: A minimum of 2 years and a maximum of 20 years in prison and up to $10,000 in fines.
  • Third-degree: 2 to 10 years in prison and a maximum of a $10,000 fine.
  • State jail felony: A minimum of 180 days and a maximum of 2 years in state jail with $10,000 in fines.

If you get released from jail or prison, you have to register as a sex offender with the Texas Sex Offender Registry. It might be difficult for you to find a job because most people don’t want to employ a convicted sex offender. You’re also not allowed to own a firearm, vote, or run for public office. If you want to go back to school, your conviction could prevent you from college admission or applying for grants if you do get accepted.

“He handled an unjust ticket for me and was very thorough and on time with notices, etc. His communication was short and to the point without false fluffy words or promises.”


When my son received a DWI, I wanted to get him THE BEST lawyer I could find. I researched for two days, and then I found Mark Lassiter. I looked no further. As soon as I read about him, I knew that I found THE BEST. From the moment I met him, I had COMPLETE confidence in him. At the end of my son's trial, Mr. Lassiter came through with a defense case so impressive that the case was dismissed before the prosecutors finished their argument. I will always be grateful to him.


Mark is a very intelligent professional defense Attorney on my DWI offense that Mark convinced the jury that i wasn't guilty i highy recommend Mark to my family and friends once again thanks Mark


I had my first DWI charge and I was unclear of next steps. I was getting propositioned left and right by less ethical lawyers and one even "claimed" my case and I missed my court date. However, Mark Lassiter and his amazing paralegal took care of everything. They were very prompt and clear with their communication on every step of the process. Also if anything came up I got a call right away and they let me know what I needed to do next. Honestly made this stressful situation manageable. I already recommend them to anyone who is going through the same situation as me. That said he does come at a premium cost but is worth every penny, and his team is willing to work with you on payment plans.


I recently was referred to contact Mark Lassiter by a colleague and called him for a consultation related to a recent arrest for public intoxication in Dallas. He was terrific; I had never been arrested before and was unsure of what the appropriate next steps would be. He was detailed in his step-by-step approach and provided me sound legal advice on how he would handle this case.I elected to hire him as my attorney and it was the best decision. He handled my case and was able to get the charges dismissed. As a professional it was imperative to be able to get this charge removed from my record.If you are in need of a criminal defense attorney, I would highly recommend Mark's services.


I am a very satisfied and a relived client. After meeting with various lawyers Mark was the one who won me over. Walking into his office you will be impressed of all his credentials. He is professional and aggressive which is what everyone looks for in a attorney. Every other lawyer I interviewed mentioned to "plea deal", I knew that meant settling. A DWI on my record was the LAST thing I wanted. I was very hopeless and scared (considering it was my first offense) but Mark always reassured me that I had a very good case. Ultimately, Mark did a phenomenal job in the court room (he had the prosecutors speechless), which resulted in a dismissal. I recommend this man to everyone I know. Thank you Mark, I owe you my life.
