What Is a Federal Sex Crime?

Sex crimes usually refer to non-consensual conduct or acts that are legally prohibited even when consent exists, such as prostitution, sex trafficking, or public indecency. These offenses are generally prosecuted at the state level.

Federal sex crimes cover many of the same offenses; however, you’ll have the full strength of the United States government against you instead of just the state.

Federal sex crimes bring extraordinary penalties and long-term repercussions. People convicted of these offenses often face:

  • Lengthy prison terms that may span decades
  • Mandatory minimum prison terms in certain child exploitation and trafficking cases
  • Extended federal supervision after release
  • Sex offender registration obligations
  • Housing and employment restrictions that last for years
  • Long-term harm to careers, relationships, and social standing

When Does a Sex Crime Become Federal?

Ordinarily, sex-related charges are prosecuted at the state level. A sex crime becomes federal when it intersects with federal property, interstate activity, or national communication systems like the mail or the internet.

A sex offense may fall under federal jurisdiction in Birmingham, ALvvvvv for reasons such as:

  • Crossing state lines while attempting or committing sexual offenses
  • Using the internet, social media, or apps to commit or attempt to commit a sexual offense
  • Using the mail or other interstate services to transmit unlawful items or coordinate with alleged victims
  • Offenses on federal property, covering places such as military bases, national parks, federal prisons, or federal buildings
  • Crimes that involve federal interests, involving actions connected to federal employees or federally administered programs

Who Investigates Federal Sex Crimes?

Federal sex crime investigations are typically overseen by federal agencies with extensive tools and training. These can include:

If you are contacted by one of these agencies about a sex offense, the situation is already serious. Do not speak to investigators, provide statements, or allow searches before consulting an experienced Birmingham, AL federal sex crime defense attorney.

    Types of Federal Sex Crimes We Defend in Birmingham, AL

    Dozens of federal sex crimes are listed throughout Title 18 of the U.S. Code. Our Birmingham, AL federal sex crime lawyers defend every one of them, but these are the charges we encounter most often:

    Sexual Abuse and Aggravated Sexual Abuse

    Under federal law, sexual abuse and aggravated sexual abuse include cases involving force, threats, or victims who cannot legally consent

    • Sexual assault involving force or threats
    • Conduct involving victims who are incapacitated or unable to give consent
    • Sexual misconduct involving minors or vulnerable adults on federal property

    Child Sexual Exploitation and Child Pornography

    Federal prosecutors treat child exploitation offenses with extreme severity. Common federal allegations include:

    Production charges nearly always trigger mandatory minimum terms. Possession may still bring long terms of imprisonment, lifetime release conditions, and required sex offender registration.

    Online Enticement and Internet-Based Offenses

    Federal internet sex crime statutes cover far more than child pornography. Frequently charged offenses include:

    • Coercion and enticement of a minor using the internet, text messages, or apps
    • Crossing distances to meet a person presented as a minor for unlawful sexual acts
    • Sending explicit communications to an individual thought to be a minor
    • Attempt-based charges stemming from law enforcement sting operations

    Often, these cases involve undercover 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

    Sex trafficking laws at the federal level are expansive and impose extremely harsh penalties. Sex trafficking often consists of:

    • Using force, threats, or coercion to make someone engage in sexual activity in exchange for money, shelter, drugs, or anything of value
    • Recruiting, transporting, housing, or controlling a person so they can be exploited for sexual purposes
    • Any sexual activity involving a minor where something of value is exchanged, even if no force or threats are used

    Being charged with federal sex trafficking in Birmingham, AL can result in decades-long sentences and lifetime registration.

    Kidnapping and Transport for Sexual Purposes

    Federal sex crime charges may stem from interstate movement or unlawful restraint. These situations often include:

    • Kidnapping associated with sexual criminal conduct
    • Transporting an individual from one state to another for prohibited sexual behavior
    • Transporting victims through threats, fraud, or coercion for exploitative purposes

    How Is a Federal Sex Crime Different from a State Sex Crime in Birmingham, AL?

    Federal sex crimes differ from state sex crimes in Birmingham, AL because they take place in a separate court system, follow different procedures, and usually carry more severe punishment.

    Here are the key differences:

    • Federal sex crime cases take place in federal district court before federally appointed judges and prosecutors
    • Federal rules of evidence and procedure tend to be stricter and more technical than those used in Birmingham, AL state courts.
    • Federal courts and investigators have a much higher budget than most state courts and law enforcement, along with specialized technology, digital forensics labs, multi-team task forces, multi-state investigations, and undercover agents
    • The United States Sentencing Guidelines tend to require stronger penalties and increased mandatory minimums, and sentences can be increased substantially based on the age of the victim, use of force, number of victims/images, and other aggravating factors.
