A Jamestown man already serving time in state prison has been charged with the alleged sexual assault of two girls under the age of 11.

In May 2025 the Chautauqua County Sheriff’s Office Criminal Investigation Division began an investigation into alleged sexual abuse. Devein A. Denson, 24, of Jamestown was interviewed at the state prison where he is serving time. Deputies have now charged Denson with predatory sexual assault against a child, a class A-2 felony, first-degree criminal sexual act, a class B felony, and first-degree sexual abuse, a class D felony. Denson allegedly subjected two girls under the age of 11 to sexual contact.

On Tuesday, Denson was brought back to Chautauqua County by the state Department of Corrections and Community Services. He will appear in court later.

“The Chautauqua County Sheriff’s Office remains unwavering in its commitment to protecting children and holding those who harm them accountable,” the county Sheriff’s Office said in a news release. “Crimes against children will not be tolerated in our community. Those found responsible will be identified, arrested, and prosecuted to the fullest extent of the law.”

Denson had been charged in 2022 for disseminating indecent material to minors after allegedly engaging in activity with a minor using an online social media platform between July and August 2022. The sheriff’s office said Denson is accused of sending obscene images to the minor victim.

He was arrested for second-degree disseminating indecent material to minors and endangering the welfare of a child.

A Jamestown, NY, man has been arrested after an investigation by City of Jamestown Police found he committed multiple criminal acts of a sexual nature against three juvenile victims.

In December 2023, the Jamestown Police Department’s

Juvenile Detective Bureau charged Denson with three counts use of a child in a sexual performance, promoting a sexual performance of a child and endangering the welfare of a child, two counts of third-degree criminal sexual acts, and one count of rape.
