Jordan Monroe was sentenced Thursday. The 54-year-old former Warwick resident pleaded guilty in May several child pornography charges.
The office of U.S. Attorney Aaron Weisman says authorities found more than 38,800 images and 960 videos containing child pornography after performing a court-ordered search of Monroe's home in May 2016.
The material seized includes videos of Monroe sexually assaulting a child at least 19 times over a period of at least three years.
Authorities say they also found a "manifesto for pedophiles" in his home.
