Johnathon Brown, 34, of Hamilton, was sentenced to 30 years in prison for federal child pornography crimes on Tuesday, according to a spokesperson with the Department of Justice.
Court records said Brown hid outside bedroom windows and put cameras inside a laundry basket to record minors as they got out of the shower.

“He told victims he needed to see their bodies for ‘medical reasons,’” the department said.
Brown also groomed a teenager, which started when she was 15 years old.
He eventually solicited pictures and sexual behaviors from the victim.
“The defendant used emotional ploys of suicide or self-harm to manipulate the teenager,” the department said.
Brown pleaded guilty to producing and attempting to produce child pornography in October 2025, according to the department.

In August 2024, authorities found Brown at a Montgomery County hotel with the victim.
Brown then led law enforcement on a high-speed chase that ended after he intentionally crashed into a train in Miamisburg, according to a previous News Center 7 report.
He didn’t surrender until law enforcement deployed tear gas and a K9 officer during a SWAT standoff.
Brown pleaded no contest to his initial charges of felonious assault and failure to comply with an order or signal of a police officer in April 2025.
His other state charges were dismissed, according to Warren County Court of Common Pleas records.
Brown remains booked in the Butler County Jail on a federal hold.
