Marquette County Sex Offender Registry Search

The primary tool for looking up Marquette County sex offenders is the Michigan Public Sex Offender Registry search portal, maintained by the Michigan State Police. The search is free and open to the public. You can enter a name, a street address, or a zip code, or you can select Marquette County from the county filter to pull all active registrants in the area.

Marquette County Sheriff and Local Registration

The Marquette County Sheriff's Office handles all sex offender registration in the county. The office is located at 236 W Baraga Ave., Marquette, MI 49855. The main phone number is 906-225-8435. The department's website is at co.marquette.mi.us. Sheriff Greg Zyburt oversees the office and the county's registration process.

Sheriff Zyburt brings 36 years of law enforcement experience to the role and is a graduate of the FBI National Academy, completing the program in 2000. He has also testified before a White House criminal justice panel in 2015 on matters related to public safety. That background means the Marquette County Sheriff's Office brings considerable expertise to the administration of sex offender registration and compliance in the region.

All registrants must appear in person at the sheriff's office. No online or mail-in updates are accepted. First-time registrants pay an initial $50 fee and must bring a valid photo ID, proof of current address, and vehicle documentation. The same process applies for required periodic verifications. If someone is splitting time between two locations, both addresses must be separately reported and verified.

Note: Registrants who move to Marquette County from elsewhere in Michigan or from another state must register at the sheriff's office within three business days of arriving.

Michigan Registration Law in Marquette County

Michigan's Sex Offenders Registration Act begins at MCL 28.721 and applies statewide. Under MCL 28.723, any person convicted of a qualifying sex offense must register with local law enforcement. This obligation begins before or at the time of release from custody, or within three business days of establishing a new address in Michigan. Out-of-state convictions and federal convictions can also trigger the Michigan registration requirement, depending on the nature of the offense.

Changes to any registered information must be reported within three business days and done in person at the Marquette County Sheriff's Office. MCL 28.725 lists what must be kept current: home address, work address, school enrollment, vehicle information, and other tracked details. Failing to update is a criminal violation. MCL 28.729 sets the penalties at up to four years and $5,000 for a first offense, up to seven years and $10,000 for a second, and up to ten years and $10,000 for any subsequent offense. These are felony-level consequences that can add significant time beyond any original sentence.

Sex Offender Tiers in Marquette County

Michigan uses a three-tier system under MCL 28.725a to classify every registered sex offender. Tier I covers lower-severity sex offenses including fourth-degree criminal sexual conduct under MCL 750.520e. Tier I registrants remain on the registry for 15 years and verify once each year. Tier II applies to mid-range offenses such as second-degree criminal sexual conduct under MCL 750.520c. These individuals stay on the registry for 25 years and must verify every six months.

Tier III is reserved for the most serious sex crimes. First-degree criminal sexual conduct under MCL 750.520b, which often involves penetration combined with factors such as a victim under 13, a weapon, or force, falls in this category. Tier III registrants must verify every 90 days and remain on the public registry for life. Tier levels are assigned by the Michigan State Police based on the conviction record alone. The Marquette County Sheriff has no authority to adjust a tier assignment. Any questions or disputes about a tier level must go directly to the MSP SOR unit in Lansing.

Note: Tier status applies for the full required registration period regardless of time passed since release or conduct after sentencing.
