(Portland, OR) -- An Albany man has been sentenced to federal prison for possessing child pornography as part of a multinational investigation. Matthew Windom was arrested last year while he was on probation for a 2014 child sex abuse conviction. Court records show he shared explicit material involving children on a New Zealand-based platform, called "Mega." When police searched his home they found a duffel bag of children's underwear and stories about sex abuse. Explicit photos were found on email accounts tied to Windom. He pleaded guilty and was sentenced to ten years in prison.
