Civilian Army leader led child porn ring, risked US security

This undated photo made available by the Arizona Department of Corrections shows David Frodsham. Frodsham pleaded guilty to sex abuse charges in 2016 and is serving a 17-year sentence. But records reviewed by the AP show that the U.S. Army and the state of Arizona missed or ignored multiple red flags over more than a decade, which allowed Frodsham to allegedly abuse his adopted son and other children for years, all the while putting national security at risk.
