A Bangor man faces between 15 and 110 years in prison and a $1 million fine after pleading guilty Tuesday in U.S. District Court in Bangor to using children to produce child pornography.

Timothy Klimas, 27, sexually abused three children between 2012 and 2014 and used a digital camera and his cellphone camera to record images of them and post them to a website, according to the U.S. Attorney’s office.

Klimas will be sentenced after a pre-sentence investigation report by the U.S. Probation Office.

Klimas was arrested in August 2014 following an investigation by the FBI, Bangor and Newport police departments.
