A Dayton man will spend at least the next decade in prison after a Montgomery County judge sentenced him for a sexual relationship with a 15-year-old that came to light after the teen's father reported it to police. Matthew Dazen, 29, was sentenced to 10 to 14 years behind bars in Montgomery County Common Pleas Court, according to the Montgomery County Prosecutor's Office. Judge Steven M. Abshire handed down the sentence after Dazen pleaded guilty to a reduced set of charges tied to the case.
The case began when the teen's father discovered the relationship and reported it, prompting Dayton police to open an investigation, as reported by the Dayton Daily News. Investigators reportedly found illegal images on Dazen's electronic devices during a forensic examination, a search that dramatically expanded the scope of the case. Court records show Dazen was originally indicted on 82 counts in July 2025, including 50 counts of pandering sexually oriented material involving a minor and 10 counts of creating minor sexual material, according to WHIO TV. He was arrested by Dayton police and held in the Montgomery County Jail on a $100,000 bond following the initial report.
What Dazen Pleaded Guilty To
Rather than face the full original indictment, Dazen ultimately entered guilty pleas to a reduced subset of charges. Those included 60 counts of pandering obscenity involving a minor, 10 counts of illegal use of a minor in nudity-oriented material or performance, 10 counts of disseminating matter harmful to juveniles, and 2 counts of unlawful sexual conduct with a minor, per the sentencing details. The unlawful sexual conduct charge reflects the age gap between Dazen and his victim — under Ohio Revised Code § 2907.04, sexual conduct with a 13- to 15-year-old by an offender 10 or more years older is automatically elevated to a third-degree felony carrying up to 60 months per count, according to the state's codified laws.
The sentence itself was not handed down as a fixed term. Instead, Dazen's 10-to-14-year range was imposed under Ohio's Reagan Tokes Law, an indefinite sentencing framework enacted in 2019 that requires courts to set a minimum term alongside an automatic maximum calculated at 50 percent above it, per the Supreme Court of Ohio's sentencing guidance. That structure means the Ohio Department of Rehabilitation and Correction, not the court, holds the ultimate authority over how long Dazen actually stays behind bars.
Why His Release Date Isn't Fixed
Release at the 10-year minimum is presumed unless state prison officials formally rebut it, but the department can hold Dazen past that minimum, up to the full 14-year maximum, if he commits institutional rule violations or fails behavioral rehabilitation benchmarks while incarcerated, according to Palmer Legal Defense. The framework was designed to let corrections officials keep high-risk felony offenders locked up longer if problems persist behind bars. The Ohio Supreme Court upheld the constitutionality of that arrangement in its 2023 ruling in State v. Hacker, finding that letting the executive branch extend sentences this way does not violate separation of powers or due process protections, per Justia Law's case summary.
Beyond prison, Dazen now carries a 25-year registration obligation. He was designated a Tier II sex offender, which under Ohio's e-SORN system requires registering his address in person with the county sheriff every 180 days for that entire quarter-century, according to the Franklin County Sheriff's Office. That distinguishes his case from Tier III designations, which carry lifetime registration every 90 days along with automatic community mailings to neighbors — a step Tier II status does not trigger, even though Dazen's information remains on public sex offender databases throughout the 25-year period.
The Ohio Supreme Court has already weighed in on registration requirements like these. In its 2016 ruling in State v. Blankenship, the court found that requiring an adult convicted of unlawful sexual conduct with a 15-year-old to register for 25 years does not amount to cruel and unusual punishment under either the U.S. or Ohio constitutions, according to background compiled by the Koffel Law Firm. The court reasoned that periodic address reporting is proportional to the public safety interest at stake.
A Pattern of Local Cases
Dazen's case moved through the same Montgomery County Prosecutor's Office infrastructure that handles other felony child exploitation cases in the region, including a specialized Child Abuse Bureau and a Victim/Witness Division that has supported crime victims through Common Pleas Court since 1974. Hoodline has reported on a similar Dayton indictment involving a teen relative, and separately covered a Miami Township man indicted on 31 counts following a digital forensic tip, as well as a Harrison Township man sentenced to 15 years for abusing a girl since age 6 in Montgomery County court.
