What Is a Federal Sex Crime?

These offenses typically involve either lack of consent or acts that are illegal on their own, like prostitution, sex trafficking, or indecent exposure. In most situations, sex crime allegations are handled by state courts.

  • Extended incarceration, often measured in decades
  • Mandatory minimum penalties for specific child exploitation or trafficking crimes
  • Years of supervised release following incarceration
  • Sex offender registration obligations
  • Housing and employment restrictions that last for years
  • Lifetime consequences for relationships, work opportunities, and personal reputation

When Does a Sex Crime Become Federal?

Typically, sex crime allegations begin and end in state courts. They become federal when tied to federal statutes, federal land, interstate conduct, or systems like the mail or internet.

  • Crossing state lines for sexual activity or illegal conduct related to sex
  • Using the internet, social media, or apps to facilitate or attempt prohibited sexual conduct
  • Using the mail or other interstate services to distribute illegal content or exchange communications linked to a sexual offense
  • Offenses on federal property, such as a military base, federal prison, national park, or federal building
  • Crimes that involve federal interests, including offenses involving federal workers or federal government programs

    Types of Federal Sex Crimes We Defend in Los Angeles, CA

    Federal sex crimes appear in many sections of Title 18 of the U.S. Code. Our Los Angeles, CA federal sex crime lawyers routinely handle all of them, with the following being the most common:

    Sexual Abuse and Aggravated Sexual Abuse

    Federal law covers sexual abuse and aggravated sexual abuse that involves force, threats, or alleged victims who cannot legally consent

    • Sexual assault involving force or threats
    • Cases in which a victim is impaired, unconscious, or incapable of consenting
    • Sexual misconduct involving minors or vulnerable adults on federal property

    Child Sexual Exploitation and Child Pornography

    Federal law is especially strict when it comes to child exploitation. Common charges in this area include:

    Production charges nearly always trigger mandatory minimum terms. Possession charges alone may still result in lengthy prison sentences, lifetime supervision, and mandatory sex offender registration.

    Online Enticement and Internet-Based Offenses

    Child pornography laws are only one part of federal internet sex crime prosecutions. Frequently charged offenses include:

    • Coercion and enticement of a minor using the internet, text messages, or apps
    • Going to meet someone thought to be a minor for prohibited sexual activity
    • Sending sexually explicit material to someone believed to be a minor
    • Attempt offenses involving undercover operations or “sting” cases

    These cases commonly involve agents pretending to be minors online. Charges may still be filed even if no real minor exists, based solely on the belief of communicating with a minor.

    Sex Trafficking of Adults and Minors

    Federal law on sex trafficking is sweeping and carries exceptionally severe consequences. Sex trafficking commonly involves:

    • Compelling someone through threats, force, or coercion to participate in sexual activity for money, shelter, drugs, or other benefits
    • Moving, recruiting, or controlling a person for sexual exploitation
    • Conduct involving a minor in which something of value is traded, even without threats

    A federal sex trafficking conviction in Los Angeles, CA may result in decades behind bars and mandatory lifetime registration.

    Kidnapping and Transport for Sexual Purposes

    Certain federal sex crime allegations arise when someone is transported across state lines or detained unlawfully. Examples include:

    • Kidnapping linked to sexual exploitation
    • Transporting someone across state lines for illegal sexual activity
    • Coercing or deceiving victims into travel for exploitation

    • Federal rules of evidence and procedure tend to be stricter and more technical than those used in Los Angeles, CA state courts.
    • Federal investigators and courts operate with significantly larger budgets, advanced technology, digital forensics units, cross-agency task forces, and undercover operations
    • The United States Sentencing Guidelines often have harsher sentences and higher mandatory minimums, with sentences often enhanced significantly based on the victim’s age, use of force, number of images or victims, and other aggravating factors.
