Charles Reambonanza, a 33-year-old former South Dakota teacher, has entered a guilty plea for possessing child pornography.
On Monday, he admitted to purchasing illicit images via PayPal and an app from an individual in the Philippines.
Prior to his arrest, Reambonanza served as a science teacher at St. Francis Indian School, where he was suspended once allegations came to light.
When he receives his sentence, he could potentially face a minimum of five years of supervised release and a maximum of 20 years in federal prison.
