A Mashpee resident and former New York pediatrician pleaded guilty to charges of distribution of child pornography and possession of child pornography in federal court in Boston Wednesday, according to a release from US Attorney Carmen Ortiz's Office. Daniel O'Hern, 64, will be sentenced on July 21.
O'Hern's Mashpee condominium was raided in June 2014 after authorities discovered in May that he had been posting sexually explicit images and video of children online via a public file sharing program. The children, between the ages of 5 and 12 were depicted in sexually explicit encounters with adults, according to the release.
During the raid, police confiscated several computers, external hard drives, media storage devices and hundreds of DVDs containing images and video of children being sexually assaulted by adults.
At the time of his arrest, O'Hern was semi-retired. O'Hern had previously practiced medicine in Middleton, New York with Dunning Road Pediatrics and Crystal Run Healthcare. He is the author of "Common Sense Pediatrics for Parents" published by America Star Books in 2011. According to the book's description on Amazon.com, it represents O'Hern's "thirty years of experience in pediatrics" and was written "for the lay person".
O'Hern had remained in custody until his indictment in August 2014.
On the charge of distribution of child pornography, O'Hern faces a mandatory minimum sentence of five years to no greater than twenty years in prison followed by a minimum five years to a lifetime of supervised release. He will also be required to register as a sex offender. On the charge of possession of child pornography, O'Hern faces no greater than ten years in prison followed by a lifetime of supervised release, according to the release.
The case was prosecuted by Assistant US Attorney Kenneth G. Shine of Ortiz's Major Crimes Unit. The case was heard by US District Court Judge Denise J. Casper. The investigation was conducted by US Attorney Carmen Ortiz's Office, the US Postal Inspection Service, the Mashpee Police Department and the Barnstable Police Department.
