What Is a Federal Sex Crime?

Sex crimes generally involve non-consensual acts (like rape) or sexual acts that are consensual but illegal in and of themselves (like prostitution, sex trafficking, or indecent exposure). Ordinarily, state authorities handle these types of charges.

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:

  • Extremely long federal prison sentences
  • Mandatory minimum prison terms in certain child exploitation and trafficking cases
  • Long periods of supervised release after prison
  • Mandatory sex offender registration
  • Rules restricting where a person may work or live
  • Lifetime consequences for relationships, work opportunities, and personal reputation

When Does a Sex Crime Become Federal?

Most sex crimes are generally charged 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.

Federal prosecutors in Scottsdale, AZvvvvv often take over sex crime cases when one of the following applies:

  • Crossing state lines in connection with unlawful sexual behavior
  • Using the internet, social media, or apps to initiate, plan, or attempt an illegal sexual act
  • Using the mail or other interstate services to send prohibited materials or messages related to a sexual crime
  • Offenses on federal property, including military installations, federal prisons, or national parks
  • 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 managed by agencies that have specialized staff and powerful investigative resources. These can include:

If you are contacted by one of these agencies about a sex offense, the situation is more serious than it may appear. Do not engage with questioning, make comments, or authorize searches without first consulting an experienced Scottsdale, AZ federal sex crime defense attorney.

    Types of Federal Sex Crimes We Defend in Scottsdale, AZ

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

    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

    Child exploitation laws at the federal level are among the strictest in the criminal code. The most frequent offenses in this category include:

    Production-related offenses routinely carry mandatory minimum prison 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. Typical charges include:

    • Coercion and enticement of a minor through internet-based communication or messaging apps
    • Crossing distances to meet a person presented as a minor for unlawful sexual acts
    • Sending sexually explicit material to someone believed to be a minor
    • Attempt-based charges stemming from law enforcement sting operations

    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 sex trafficking statutes are wide-reaching and come with some of the toughest punishments. Sex trafficking generally includes:

    • Compelling someone through threats, force, or coercion to participate in sexual activity for money, shelter, drugs, or other benefits
    • Directing, moving, or sheltering individuals to facilitate sexual exploitation
    • Any sexual conduct with a minor tied to compensation or exchange, regardless of force

    Being charged with federal sex trafficking in Scottsdale, AZ can result in decades-long sentences and 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 connected to sexual misconduct
    • Crossing state lines with someone for illegal sexual acts
    • Transporting victims through threats, fraud, or coercion for exploitative purposes

    How Is a Federal Sex Crime Different from a State Sex Crime in Scottsdale, AZ?

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

    Key differences:

    • Federal judges and prosecutors handle these cases in federal district courts
    • Federal rules of evidence and procedure tend to be stricter and more technical than those used in Scottsdale, AZ 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 typically impose far harsher sentencing ranges and strict mandatory minimums, and penalties increase sharply when factors like victim age, force, number of victims/images, or other aggravating factors are involved.
