Details have emerged concerning the alleged sexual abuse of a 13-year-old boy by 17-year-old Noah William Schaefer of Morgan's Point.

Schaefer was arrested Thursday and charged with aggravated sexual assault of a child. As of Tuesday evening, he had posted $100,000 bond and been released from the Bell County Jail.

Our news partner, KWTX, reports that the victim's mother contacted police after finding her son pants-down in a room with Schaefer at a party on February 11. The woman reportedly confronted Schaefer and told him to never touch the child again. Once home, the child told his mother Schaefer had sexually abused him orally, anally, and in other ways for years.

According to an affidavit obtained by KWTX, the victim and his younger brother recounted the abuse to an interviewer with the Child Advocacy Center of Waco.
