Federal prosecutors in Maine say a 58-year-old Sebago man has pleaded guilty to federal charges stemming from possession of child pornography.
Prosecutors say William Duffy faces up to 20 years in prison, a $250,000 fine and supervised release that could last for life. He will be sentenced after the completion of a pre-sentence report.
Court records say sheriff's deputies executed a search warrant on Duffy's laptop at his Sebago home in May 2015. An analysis revealed numerous images and video files depicting child pornography.
Duffy's Attorney Tim Zerillo, of Portland, did not immediately respond to a phone call seeking comment about the case.
The FBI and Maine State Police Computer Crimes Unit investigated the case along with local authorities.
