New Hampshire Resident Sentenced to 6 Years in Prison for Possessing Child Pornography

On May 30, 2018, William Pothier, a former FAA aviation safety inspector, Exeter, New Hampshire, was sentenced in U.S. District Court, New Hampshire, to serve 72 months in prison, register as a sex offender, 20 years’ supervised release, a $5,000 fine, and a $5,100 special assessment fee. On February 13, 2018, a jury convicted Pothier for possession of child pornography. 

In January 2016, the Exeter Police Department received information that an IP address affiliated with a local residence was sharing child pornography using Shareaza, a peer-to-peer, file-sharing software. Further investigation by the New Hampshire Internet Crimes Against Children (NHICAC) Task Force led to Pothier. On March 30, 2016, members of the NHICAC Task Force executed a State search warrant at his residence. A forensic examination of the laptop seized during the search discovered videos and thumbnail images of child pornography. 

DOT-OIG conducted this investigation with the FBI; NHICAC Task Force members from the Exeter, Portsmouth, and Hampton Police Departments; Strafford County Sheriff’s Office; and U.S. Attorney’s Office, District of New Hampshire.
