A central New Jersey woman who sexually assaulted a 5-year-old girl she was babysitting and put a video of the abuse on the Internet has been sentenced to 30 years in federal prison.

Thirty-three-year-old Manalapan resident Jennifer Mahoney will be under lifetime supervision once she's freed from prison. She pleaded guilty in May to sexual exploitation of a child and was sentenced Tuesday.

Mahoney admitted sexually assaulting the girl and streaming the assault live over a video chat service. She also admitted abusing the girl on another occasion, recording the abuse on a camera phone and emailing the video to at least one other person.

She said she viewed other videos of child sexual abuse streamed to her using a video chat service.
