False Accusations of Sex Crimes

False accusations of sex crimes and sexual assault can ruin a person's life. A sex crime conviction can mean lengthy prison sentences and lifetime registration as a sex offender, not to mention the loss of respect among your peers. No criminal charge comes with a stronger presumption of guilt than does a sex crime.


Most people presume guilt when someone is accused of a sex crime, assuming that children and other victims would never falsely accuse someone of a sexual assault charge. In reality, false accusations of sex crimes occur more often than courts would like to admit. An innocent person falsely accused of sexual assault should contact an experienced sexual assault attorney immediately. Many sex crimes can be dismissed after prompt and diligent investigation.

When to Hire a Sexual Assault Attorney

As soon as you or a loved one learns that he or she has been accused of sexual assault, it is time to hire a sexual assault attorney. It is important that you speak with an experienced criminal attorney before speaking with the police. The police may encourage you to make incriminating statements that can be used later against you. The police may say things like "We just want to hear your side of the story" and "We just need to clear some things up". If you are getting phone calls from the police regarding a sexual assault allegation, it is time to hire a Houston sexual assault attorney. 

Sexual Assault Case Makes Houston News Headlines

In 2006, sexual assault attorney John "Casey" Keirnan made Houston news headlines when he successfully argued a motion to have a sexual assault case moved out of a judge's court. Mr. Keirnan argued that the judge illegally denied his client bail, thus denying the accused his due process rights. In the motion, Mr. Keirnan noted that his client, charged with two counts of sexual assault of a child, could not receive a fair trial due to a biased and prejudiced judge who was randomly and arbitrarily denying bond to the accused in sexual assault cases.
