A Leesburg man was sentenced to 225 years in prison on Wednesday for child pornography found on his phone in 2023.
In the courtroom of Judge Brian Welke, jurors found 55-year-old John Jospeh Marchlewski guilty on all 15 counts of possession of child pornography (10 or more images). He was consecutively sentenced to 15 years in prison on each charge, cumulating a 225-year sentence.

“Of the disturbing videos this defendant possessed of very young children being sexually abused, one was less than two years old – just a toddler. The mere thought of someone abusing a toddler, or any child, for their own sexual gratification is sickening,” said Bill Gladson, Fifth Judicial Circuit State Attorney. “My office remains unwavering in combatting child sexual exploitation and abuse. Whether you are the pedophile producing the material or the deviant viewing and sharing it, we will charge you and make sure you are punished to the fullest extent possible by law.”
Marchlewski was arrested in May 2023 following a Florida Department of Law Enforcement investigation after law enforcement officials received a cyber tip from the National Center for Missing and Exploited Children indicating an online user had uploaded files containing child pornography.
During their investigation, officials determined that Marchlewski, a registered sex offender, was the owner of the accounts that contained child sexual abuse material. After obtaining a search warrant, detectives responded to Marchlewski’s residence, where they made contact with the defendant and seized his cellular device. A forensic examination of his device was conducted, revealing the files containing the child pornography.
Assistant State Attorneys Tyler Duffy and Karli Hurbanis prosecuted this case.
