How to Define Sex Crimes

A sex crime is a category of criminal offenses that occur when one party forces a sexual act on another through violence or physical force and without consent.

Violence and Lack of Consent

Many sex crimes involve offensive behavior. Sexual assault is a forced and unwanted sexual act performed on one person by another without receiving consent. It can include battery, threats, and other forms of violence. It consists of sexual contact, such as touching, kissing, or penetration.

When someone engages in sexual intercourse because of a threat of force from another person, that offense is known as rape. This type of sex crime requires a lack of consent. If the victim did not consent to the sexual act, the offender could be convicted of rape.

Crimes Against Children

Children can’t give consent to sexual acts under Texas state law. It’s a crime to engage in any form of sexual touching with a minor child. Child molestation occurs when an adult commits a sexual act against a child.

Prosecuting a sex crime involving a child can be difficult. Children sometimes experience false memories. Some children might wrongfully accuse an adult of a sex crime if their parents are going through a divorce or they don’t like their foster parents.

Public Sex Crimes

Some sex crimes happen in a public area. For example, public indecency involves individuals exposing themselves or behaving in an inappropriate sexual manner in front of other people. Sexual misconduct is another charge that applies to sexual acts that bystanders find offensive.

Types of sex crimes include:

  • Child Molestation
  • Indecency with a Child
  • Internet Sex Crimes
  • Juvenile Sex Crimes
  • Possession of Child Pornography
  • Public Lewdness
  • Rape and Aggravated Sexual Assault
  • Sex Offender Registration Violations
  • Sexual Assault
  • Sexual Trafficking of a Child
  • Solicitation of a Minor
  • Solicitation of Sex and Prostitution
  • Statutory Rape

How to Defend Your Sex Crime Charge

Every case is different and includes a different set of circumstances. However, there are common defenses Law Offices of Mark T. Lassiter might use to get your sex crime charge dropped.

Innocence: It’s possible that you didn’t commit the crime. To prove your innocence, we’ll review all available evidence and witness testimony to poke holes in the prosecution’s story. We may be able to document an alibi that shows you were nowhere near the scene of the crime at the time it occurred.

Tainted evidence: Sometimes, the evidence collected while building a case becomes tainted. For example, statements an officer makes while questioning a child could introduce false memories of what actually happened. If we find that any evidence the prosecution found is unreliable, we’ll ensure a jury can’t see it during the trial.

Illegal search and seizure: The Fourth Amendment protects citizens from illegal searches and seizures. If law enforcement searched your property and removed any belongings without a search warrant, prosecutors can’t present it to the jury in court.

Hearsay: Some sex crime cases turn into a “he said, she said” situation. Sometimes the alleged victim’s motive is to paint another person in an unpleasant light to gain custody of their child during a divorce. As a result, they might wrongly accuse their spouse of sexually harming them in some way.

Lack of medical evidence: When investigating a sex crime, officers will look for DNA evidence. If there isn’t any forensic evidence linking you to the crime, it will be challenging for the prosecutor to convince a jury that you’re guilty beyond a reasonable doubt.

Mental illness: Some sexual offenders have a mental illness that prevents them from understanding the gravity of their actions. An insanity or mental illness defense could result in a less harsh penalty if we can prove this to the jury.

“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.
