Types of Sex Crime Charges We Defend in California

California law covers a broad range of sex offenses, from misdemeanor lewd conduct to serious felonies carrying life sentences. We’ve been defending clients against these charges for over 25 years and have handled cases across the full spectrum. We can build a defense if you’ve been charged with any of the following:

Internet sex crimes, including possession or distribution of child pornography and online solicitation of minors, are an increasingly common category of charges. These cases are often investigated digitally for months before an arrest is made, which is one reason why retaining a sex crime defense attorney in Rancho Cucamonga as early as possible matters. Each charge type carries distinct legal elements, potential penalties, and available defenses. Our approach is tailored to the specific facts of your case, not a generic playbook.

What Are the Penalties for Sex Crimes in California?

Sex crimes carry severe legal consequences in California. Penalties depend on the specific offense, the circumstances of the case, and any aggravating or mitigating factors.

Common penalties for sex crime convictions in California include:

  • Prison Sentences – Felony rape convictions can carry base sentences of 3, 6, or 8 years in California state prison, with enhanced sentences if the victim is a minor, a weapon is used, or multiple perpetrators are involved. Even misdemeanor sex offenses can result in jail time depending on the severity of the charge.
  • Sex Offender Registration – Under California’s tiered Sex Offender Registration Act, registration may be required for 10 years, 20 years, or lifetime, depending on the tier assigned to the offense. Registrants may face restrictions on where they can live, work, and travel.
  • Fines – Misdemeanor sexual battery can carry fines up to $2,000; felony sexual battery can reach $10,000.
  • Probation – Some individuals convicted of sex crimes receive probation instead of, or in addition to, prison time. Probation typically involves regular check-ins with a probation officer, drug testing, and participation in counseling programs. Violating probation can result in additional jail or prison time.
  • Community Service – Some convictions carry mandatory community service as an additional requirement alongside fines and probation.
  • Counseling and Rehabilitation – Those convicted of offenses involving sexual violence or abuse may be required to complete counseling or rehabilitation programs, often as a condition of probation or parole.

We’re dedicated to minimizing these consequences by negotiating alternative sentences where possible and pursuing lesser charges when the facts support it. Whether you’re facing misdemeanor or felony charges, we can investigate the facts, challenge the prosecution’s evidence, and explore every available defense.

Aggravating Factors in Sex Crime Cases

California courts consider aggravating factors at sentencing that can push a sentence toward the upper term or trigger enhancements beyond the base range. A prior sex crime conviction can eliminate judicial discretion entirely, resulting in mandatory minimum sentences. Understanding how these factors apply to your case is essential to building an effective defense.

  • Prior Convictions or History of Offending: Repeat offenders face enhanced penalties, including mandatory minimum sentences.
  • Victim’s Age: Charges involving minors carry harsher penalties under California law.
  • Use of Force or Violence: Crimes involving physical harm, threats, or weapons lead to more severe sentences.
  • Multiple Victims: Cases involving multiple victims or vulnerable individuals can result in increased charges and penalties.
  • Position of Trust or Authority: Offenses committed by individuals in positions of trust result in more serious charges.
  • Use of Drugs or Alcohol: Impairing the victim to facilitate the crime can lead to enhanced penalties.

Our defense team examines these factors carefully, looking for inconsistencies and building mitigating evidence that can reduce their weight at sentencing.

Defending Against Sex Crime Charges in California

The prosecution must prove guilt beyond a reasonable doubt, and absence of DNA evidence, unreliable witness identification, or procedural violations by law enforcement can all create that doubt. Our defense strategies are built around the specific facts of your case, not a checklist.

Common defenses include:

  • False Allegations False accusations of sexual misconduct do occur. Kirk Tarman can thoroughly investigate the circumstances to uncover inconsistencies in the accuser’s account, including calling witnesses, presenting evidence, and directly challenging credibility.
  • Mistaken Identity – If there were multiple suspects or the victim misidentified you, a thorough investigation can surface alibi witnesses, surveillance footage, or conflicting statements that support your position.
  • Entrapment – If law enforcement induced or coerced you into conduct you wouldn’t have otherwise committed, entrapment may be a viable defense.
  • Lack of Criminal Intent – Some charges, such as indecent exposure or prostitution, require proof of criminal intent. If we can show intent was absent, the charges may be reduced or dismissed.
  • Coercion or Duress – If you were coerced into an act under threat of harm, evidence of that duress can be central to your defense.
  • Consent – Consent is a recognized defense under California law and can be supported through digital communications, forensic evidence, or witness testimony.

Kirk Tarman’s hands-on approach includes challenging forensic evidence, exposing inconsistencies in accuser statements, and identifying constitutional violations such as improper searches or interrogations. When law enforcement has overstepped, evidence can be suppressed and charges may be reduced or dismissed.

Practicing in the Rancho Cucamonga District Courthouse

Sex crime cases in this area are handled at the Superior Court of California, County of San Bernardino, Rancho Cucamonga District. That courthouse processes arraignments, preliminary hearings, bail motions, and trials for both misdemeanor and felony criminal charges. Our attorneys appear there regularly and stay current on local court procedures through ongoing continuing legal education.

San Bernardino County courts operate within California’s statewide framework, but have their own procedural norms. Familiarity with local prosecutors and judicial preferences shapes bail decisions, plea negotiations, and how a defense is built and presented. That kind of ground-level knowledge comes from consistent practice in one courthouse, not from parachuting in from outside the area.

The Stakes of a Sex Crime Conviction Go Beyond Prison

A conviction doesn’t end when a sentence does. Sex offender registration under California’s tiered Sex Offender Registration Act can mean denial of housing, loss of professional licenses, restrictions on internet access, and barriers to employment that follow a person for decades. An allegation alone, even before any finding of guilt, can damage professional relationships and personal standing in the community.

We work to protect our clients’ rights at every stage, from the initial investigation through trial if necessary. If you’ve been charged with a sex crime, contact our office immediately to schedule a free case evaluation. The earlier we can begin building your defense, the more options may be available to us.
