BOSTON (WWLP) - A man from Harwich was sentenced to prison after co-workers reported seeing media files in the process of downloading on his cell phone, with names that were consistent with child sexual abuse material (CSAM). According to the Department of Justice, 37-year-old Jonathan Fleischman n was arrested in May 2023 when his co-workers in Brewster reported him to law enforcement. In March 2023, Fleischmann’s cellphone was observed downloading suspected child pornography media files while his phone was left open and charging on a counter at their workplace. Mass. babysitter charged with manslaughter after child dies in car During the investigation, police revealed approximately 255 image files and 55 video files that contained suspected child pornography were identified.  In custody since May 2023 for this case, Fleischmann was sentenced for a different case on May 2024 to 12 years in state prison in connection with a home invasion in Yarmouth. In 2020, he invaded a home in Yarmouth by forcibly taking a 16-year-old girl at gunpoint into her house as she arrived home from school. The investigation revealed that he had accessed a dark web hidden service on his cellphone dedicated to the trafficking of child pornography. Before the Yarmouth incident, Fleishmann was registered as a level 3 sex offender for indecent assault and battery on a child under 14 in 2006 and open and gross lewdness in 2017. On Monday, Fleischmann pleaded guilty to one count of possession of child pornography and was sentenced to 10 years in prison, which will run concurrently with the state sentencing, to be followed by five years of supervised release and ordered to pay restitution in the amount of $7,500. “Despite his prior predatory behavior and the fact that he was already facing serious charges in state court – charges that involved ambushing and attempting to kidnap a young girl at gunpoint outside her home – this defendant continued to demonstrate a complete disregard for the safety and well-being of children by downloading hundreds of atrocious CSAM from the dark web. Each image and video he viewed or shared re-victimized the real, vulnerable children depicted in them. These crimes do not exist in a vacuum; they cause significant harm to the children and families affected,” said United States Attorney Leah B. Foley. “Today’s sentence reflects the seriousness with which we treat these crimes and our commitment to protecting children from individuals like Mr. Fleischmann, who refuse to learn or take steps toward remediating their vile tendencies.” “Over and over, Fleischman committed deeply disturbing sex crimes aimed at children. For years, he has been a threat to the community but after today’s sentence, he will be off the streets for a decade,” said Homeland Security Investigations New England Special Agent in Charge Michael J. Krol. “Child sexual abuse material immortalizes the abuse of a child and those who download, trade, and possess CSAM are perpetuating the trauma those children experienced. We are committed to protecting kids and seeking justice for those victimized through child exploitation.” Local News Headlines Maureen Neal, wife of Congressman Richard Neal, has died Chicopee law enforcement to conduct emergency training at Memorial State Park Belchertown police recover rifles, search for suspect Massachusetts sex offender remains in prison for downloading over 300 files of child porn WWLP-22News, an NBC affiliate, began broadcasting in March 1953 to provide local news, network, syndicated, and local programming to western Massachusetts.
