Greenfield man sentenced to prison for unlawful sexual conduct with a minor

A Greenfield man was sentenced last week to two years in prison after pleading guilty to unlawful sexual conduct with a minor.

Tyrell M. Knisley, 29, was indicted by a Highland County grand jury in October and charged with the third-degree felony. During a period of several months in 2025, Knisley was accused of “engaging in sexual conduct” with a victim under the age of 16. 

According to court records, Knisley pleaded guilty to the charge Nov. 19. 

After accepting Knisley’s guilty plea, Highland County Common Pleas Court Judge Rocky Coss sentenced Knisley to a definite determinate term of 24 months in prison. Knisley had 61 days of jail time credit.

In addition, Knisley will be classified as a tier II sex offender, requiring registration every 180 days for 25 years.
