Jennifer Mahoney, of Manalapan, New Jersey, admitted on Wednesday to sexually assaulting a 5-year-old girl that she was babysitting and streaming the sex assault live over a video chat service on the web.
Mahoney pleaded guilty in U.S. District Court to sexual exploitation of a child and faces between 15 and 30 years in prison.
Mahoney would be under supervised release for anywhere between five years and life after her sentence is completed. She also agreed not to appeal.
In December 2011, police found three pornographic videos showing assaults of the child on the computer of Robert Ramos Jr. of Austin, Texas, and traced the attacks back to Mahoney.
Prosecutors in Texas say Ramos set up seven fake Facebook accounts to solicit teenage girls to send him nude photos and videos of themselves in sex acts. Ramos was charged with possession of child pornography and sexual exploitation of minors
