Why You Need to Treat Sex Crime Charges Seriously in Simi Valley, CA

Simi Valley, CA treats sex crime accusations very seriously. Without an experienced sex crimes attorney, you could be facing:

  • Incarceration
  • Mandatory or discretionary sex offender registration under Penal Code § 290
  • Frequently, notifications to the public regarding your conviction
  • Many collateral consequences
  • A federal firearms ban and, in some cases, passport restrictions

Trying to "clear it up" with police, the accuser, or a school or Title IX office almost always makes the file worse. You need counsel who will protect the record and the rest of your life.

What to Do if You Have Been Accused of a Sex Crime in Simi Valley, CA

  • Do not contact the accuser — No matter what your intentions are, it's a bad idea. This can hurt your case in the long run.
  • When interviewed, don't answer questions. Plead the Fifth Amendment and politely ask to speak with your lawyer.
  • Don't give permission to search your property if there isn't a warrant for it and if you don't have a defense attorney present.
  • Preserve everything. Don't delete texts, photos, apps, location history, or social media — deletion is often argued as consciousness of guilt.
  • Write a private timeline for your lawyer only: It's important that your lawyer has a full view of the situation.
  • If given bail conditions, take every effort to adhere to them — if you don't, it can make you look guilty in the eyes of the jury.
  • Get help handling the pressure — handling criminal charges is stressful, and it's normal to need some professional help.

Early counsel can sometimes intervene before filing, especially in online sting, statutory, and "he said / she said" investigations.

Get Help With the Following Simi Valley, CA, Sex Crime Charges

Rape and Sexual Assault

Rape and sexual assault are probably the worst types of sex crimes to be charged with in Simi Valley, CA. Rape, in particular, is treated extremely harshly for allegedly using force to coerce someone into sexual intercourse. "Sexual assault" is not one statute — it often means rape, sexual battery (PC § 243.4), nonconsensual oral copulation (PC § 287), sodomy (PC § 286), or penetration with a foreign object (PC § 289).

In the past, a rape accusation between spouses had different consequences that were considered more lenient. Today, though, this no longer applies, and alleged rapes between spouses are treated the same as any other.

Child Sex Crimes

Child sex crimes are some of the most harshly viewed accusations in Simi Valley, CA, making it essential to work with an experienced sex crimes lawyer to fight them. California does not have a Romeo and Juliet law, so it's illegal for an adult to have sex with a minor even if they are close in age.

Statutory Rape

Not every statutory rape charge is the same, but all of them are serious. If the alleged victim was within 3 years of the alleged offender's age, it is a misdemeanor. Anything beyond that, and the prosecution has discretion to charge the crime as a felony. Additionally, there can be enhanced penalties if the alleged offender is over the age of 21 and the alleged victim is under the age of 16.

Internet and Digital Sex Crimes

Internet sex crimes are unique in that they don't always involve a direct action being taken against the victim. For example, possession of child pornography is a crime whether or not you were the one to produce it. Possession can be charged as either a misdemeanor or a felony, while distribution or production is always a felony.

Prostitution and Related Offenses

Prostitution is illegal in much of the United States ostensibly for moral reasons. In California, prostitution-related crimes include the act of prostitution itself, soliciting a prostitute, and pimping/pandering (AKA helping someone else break a prostitution law for a profit). What this ultimately means is that involvement with prostitution can lead to criminal charges from any angle, even if it was a sting operation. Don't take these charges lightly — your Simi Valley, CA, sex crimes lawyer can help you find a positive outcome.

Related Charges

In Simi Valley, CA, we also defend indecent exposure (PC § 314), lewd conduct in public (PC § 647(a)), failure to register (PC § 290.018), human trafficking (PC § 236.1), incest (PC § 285), aggravated sexual assault of a child (PC § 269), and assault with intent to commit a sex offense (PC § 220).

How We Defend the Case

Pre-filing and investigation. The fight for your freedom doesn't begin when charges are filed — it begins as soon as the authorities start to look at you. These early days are crucial for setting your case up for success — having an expert sex crimes lawyer can help you preserve exculpatory evidence and maybe even negate charges from being filed in the first place.

Discovery and forensics. We don't just let the district attorney build a case against you — we reexamine any evidence and look for inconsistencies or other weaknesses. We can also reach out to expert witnesses and forensic labs to review everything and look for alternatives to the state's narrative.

Motions. Suppression. Motions can do many things for your case. One of the first motions we often file is a motion for bail reduction. This can help you secure pretrial release. After that, we'll frequently follow with a motion to suppress evidence and/or a motion to dismiss charges.

Negotiation. A sex crime charge defense isn't just about avoiding incarceration; it's about staying off of the sex offender registry. A plea deal can be a compromise that protects your reputation.

Trial and sentencing. Not every case can be handled through negotiations. When talks break down, we use our defensive strategy to persuade the jury. And if the outcome is guilty on any charge, we'll advocate for you in sentencing.

While the majority of sex crime cases may follow these guidelines, sentencing enhancements can greatly alter the end punishment. Every case is individual. A rape conviction can also carry a separate PC § 264 restitution fine directed to victim assistance programs.

Sex Offender Registry Tiers in California

If convicted, many sex crimes require you to register at one of the three below tiers:

  • Tier 1 — typically for a 10-year term, or 5 years for most juvenile cases. Examples: most misdemeanor sex offenses fall into this tier, and some non-violent felony offenses.
  • Tier 2 — generally 20 years. Examples: many serious/violent registerable felonies that are not automatic lifetime.
  • Tier 3 — lifetime for the most serious offenses (e.g., forcible rape, many child-victim force cases, many felony child pornography convictions) and certain repeat or high-risk designations.

Rather than automatically being removed after a time period, it's on the individual to request removal after their time is up. Your sex crimes attorney can help you petition for removal from the sex offender registery.

Effective Defenses Versus Sex Crime Charges in Simi Valley, CA

  • Consent applies in several sex crime charges, since many are only illegal if a party did not consent
  • Reasonable, good-faith mistake as to the accuser's age (the "Hernandez defense," CALCRIM No. 1071) — available for statutory rape under PC § 261.5, but not available for lewd acts with a child under 14 (PC § 288) or for human trafficking (PC § 236.1), where a defendant's belief about age is not a defense as a matter of law
  • False or motivated accusation False accusations — some people use false sexual assault or rape allegations as a way to hurt another person or gain leverage in a custody battle
  • Alibi — one of the strongest defenses against a sex crime accusation is to prove you were elsewhere at the time
  • Failure of the prosecution to prove the charges against you — ultimately, it's on the prosecution to prove you are guilty beyond a reasonable doubt. If they fail to do so, we will highlight that
  • Unlawful search of phones and cloud accounts
  • Unreliable child forensic interviews
  • Entrapment in cases like prostitution
  • Technical issues with the way the case was filed

This isn't just about defense strategies; this is about telling your side of the story in a convincing way, whether it's too a district attorney, a judge, or a jury.

They were present at an event where two other individuals (charged separately) had assaulted a woman, but our client took no part in it. We presented our defense in the preliminary hearing and the case was dismissed. This also protected our client's reputation, as no records of the case are public.
  • Kidnapping (PC § 207) and Unlawful Sexual Intercourse with a Minor (PC § 261.5) — We Protected Our Client Against Prison and Sex Offender Classification. Through a defense built around consent, our lawyers secured a deal that released our client, crediting them for time served, avoiding a felony strike and sex offender registration.
  • Child Molestation (PC § 288) and Sodomy with a Child Under 10 (PC § 288.7) — Charges Dismissed at the Preliminary Hearing. Our client was being held without bail and could have been sent to prison for life, if convicted.
