CARIBOU, Maine — A Mars Hill woman remained at Aroostook County Jail in Houlton late Monday afternoon after her initial appearance on sex charges in Aroostook County Superior Court in Caribou.

Aroostook County District Attorney Neale Adams said Monday afternoon that Julie M. Carr, 30, of Mars Hill was in court on charges of gross sexual assault and sexual exploitation of a minor.

Carr appeared before Superior Court Justice Kevin Cuddy by videoconference. Bail was set at $100,000 surety or $50,000 cash with conditions, including having no contact with anyone under age 18.

Adams said that Carr was not expected to enter a plea at Monday’s hearing, and a status conference on the case is scheduled for Sept. 18. Carr has not yet retained an attorney, but requested a court-appointed lawyer.

Adams said that affidavits related to the case are being withheld in order to assure that Carr receives a fair trial.

Carr was arrested late Friday evening at her Mountain View Street residence after state police detectives and federal agents from Immigration and Customs Enforcement and the Maine Drug Enforcement Agency carried out a search warrant at her home.

ICE agents, who gave details about an ongoing investigation into child pornography on the Internet, contacted state police investigators. West Midlands Police in the United Kingdom contacted ICE agents. Law enforcement officials in that country were investigating child sexual abuse when they discovered recorded videos showing a woman committing sexual acts on a young child.

The U.K. investigation revealed that the United States was the likely origin of the videos, which reportedly had been recorded from a live webcast. Police discovered the point of origin likely was in Mars Hill.

Additional information reportedly confirmed that the woman in the video from the U.K. was Carr. Police then secured a search warrant for the Carr residence.

Authorities uncovered evidence related to the crime during the search carried out Friday evening, although police provided no details about the evidence gathered.
