BANGOR — A Maine woman who acknowledged performing sex acts on a 2-year-old child while a man in the United Kingdom watched live via a webcam has been sentenced to 20 years in prison.

Julie Carr, 33, of Mars Hill, was sentenced Monday, a year after confessing that she sent videos to the man.

U.S. District Judge John Woodcock said he had dealt with many child pornography cases and “yours is the worst case I’ve ever seen.” The Bangor Daily News said he told Carr that “it is incumbent upon me to protect … the people who can’t protect themselves.”

Police in the West Midlands region of England discovered the videos, which were recorded by Nicholas Wilde, in June 2009 while investigating another child pornography case.

The videos were traced to Maine, and Carr was arrested two days later. She said Wilde “conned” her into doing it, according to court documents.

Carr’s four children – three daughters and a son – were removed from her custody, Assistant U.S. Attorney Todd Lowell said.

“The children are doing well,” Lowell said Monday. “In a real way, her children have been rescued and saved.”
