How do sex offense investigations begin in Arizona (Phoenix)?

Sex crime investigations often begin long before an arrest. Agencies like the Phoenix Police Department and Maricopa County Sheriff’s Office (MCSO) use digital forensic tools to analyze large volumes of evidence, including social media data and recovered deleted files and videos.

Can an arrest warrant be issued before charges are filed in an Arizona sex offense case?

Yes. Under the recently updated ARS 13-03897, a pre-charge arrest warrant can be issued, which may lead to a sudden arrest, often before you even know you are being investigated.

How are sex crimes typically indicted in Arizona?

In many cases, prosecutors go straight to a Grand Jury, where only prosecutors present evidence. The standard of proof in that proceeding is probable cause, which can make it easier for the State to secure an indictment.

What are the sentencing rules for dangerous crimes against children sex offenses in Arizona?

Sex crimes classified as dangerous crimes against children under Arizona Revised Statute 13-705 carry a mandatory prison sentence. As of 2026, Arizona applies flat-time sentencing for these crimes, meaning a sentence reduction is not possible and individuals must serve every single day of their sentence with no chance of early release.

How are Arizona Sex Offense Charges Prosecuted?

Q: Do you have to register as a sex offender if convicted in Arizona?

Yes. If you are convicted, you are required to register on the Arizona Sex Offender Registry, which is often a lifetime registration. This registration includes additional rules, restrictions, timelines, fees, and disclosures as defined by ARS 13-03821.

As technology advances, Arizona sex offense charges are becoming more digitally integrated. The prosecution of sex offenses is aggressive and the rules are evolving. Hiring a knowledgeable sexual assault defense attorney with prosecutor experience should be your first step if you are under investigation for sexual assault, sexual abuse, sexual conduct with a minor, or any other sex crime. Here is a general guide of how Phoenix prosecutes these cases today.

Sex Offense Investigation and Pre-Charge Phase

Often times sex crime investigations begin long before an arrest. For example, the Phoenix Police Department or Maricopa County Sheriff’s Office (MCSO) now have access to digital forensic tools that help them analyze large volumes of evidence all at once. This may include social media data, recovering deleted files, videos, and more. Under the recently updated ARS 13-03897, a pre-charge arrest warrant can be issued. This may then lead to a sudden arrest and often before you even know you are being investigated.

Grand Jury Indictment

Arizona takes sex crimes very seriously and, in most cases, these are prosecuted as felonies. Prosecutors often go straight to a Grand Jury which is a proceeding where only prosecutors present evidence. For the proceeding, the standard of proof is only probable cause. This can make it fairly easy for the State to secure an indictment. As a result, you will want an Arizona criminal defense attorney with strong sex crime cases on your side. Your attorney can then attempt to intervene during this stage and request that exculpatory evidence be considered by the Grand Jury. A Phoenix sex crimes attorney may also be able to challenge the State’s evidence if it is flawed or was obtained in violation of your rights.

Your Defense Matters

Cases defined by Arizona Title 13, Chapter 14 and Chapter 35.1, often rely on he-said, she-said testimony or digital evidence. This can open the door to possible constitutional violations, forensic challenges, and false allegations. Hiring an Arizona criminal defense attorney experienced in sex crime cases can review your case and develop a strong defense strategy.
