Mashpee resident, former pediatrician sentenced on child pornography charges

Daniel J. O'Hern pleaded guilty to distribution and possession of child pornography in April

A Mashpee resident and former New York pediatrician was sentenced for possession and distribution of child pornography in US District Court in Boston Tuesday. According to a release from US Attorney Carmen Ortiz's Office, US District Court Judge Denise Casper sentenced 65-year-old Daniel J. O'Hern to 63 months in prison.

In April, O'Hern pleaded guilty to possession and distribution of child pornography in federal court. 

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 an earlier 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.

In addition to the 63 months in prison, Judge Casper sentenced O'Hern to five years of supervised release following his sentence. He must also pay a fine of $12,500.

Once released from prison, O'Hern will be required to file with the Massachusetts Sex Offender Registration Board as a sex offender, the release said.

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, it represents O'Hern's "thirty years of experience in pediatrics" and was written "for the lay person".

O'Hern has been in custody since his indictment in August 2014.
