A Midland man could spend the next 15 to 30 years behind bars for advertising child pornography.
39-year-old Jason Trott pleaded guilty to the crime in federal court.
He was arrested back in May after he used a file sharing site to download and share child pornography.
Trott uploaded more than 600 images between October of 2012 and March of 2013.
A sentencing hearing for Trott has not been scheduled yet.
