OGDENSBURG -- A retired Ogdensburg police detective has received a 15-year federal prison sentence for child pornography.

Harry McCarthy, 58, Ogdensburg, was sentenced on a charge of sexual exploitation of a minor, according to United States Attorney Grant C. Jaquith.

As part of his guilty plea, McCarthy admitted that in 2013 and 2014, he used a minor to engage in sexually explicit conduct for the purpose of producing images of that conduct, according to Jaquith’s office. At the time of his crime, McCarthy was employed as an officer at the City of Ogdensburg Police Department.

McCarthy’s original arrest in 2016 was the result of an investigation conducted by the New York State Police Computer Crimes Unit and Troop B, in cooperation with the City of Ogdensburg Police Department.

Court documents say the image was uploaded using the Google Gmail service. Google apparently notified the National Center for Missing & Exploited Children of the child porn image and the addresses that were used to access the email account.

An order of protection was also issued for McCarthy's girlfriend and her children, which he allegedly violated later.

McCarthy also retired from the Ogdensburg Police Department during his time in custody. His annual salary was $73,111 not including benefits, and a felony conviction would not impact his pension, according to Ogdensburg City Manager Sarah Purdy.

Chief United States District Judge Glenn T. Suddaby also imposed a lifetime term of supervised release, which will start after McCarthy is released from incarceration, and he was fined $10,000. As a result of his conviction, McCarthy will be required to register as a sex offender upon his release from prison.

This case was investigated by the FBI and the New York State Police, and is being prosecuted by assistant U.S. attorneys Katherine Kopita and Geoffrey Brown.
