SKOWHEGAN – Details of the investigation that led to child pornography charges against a kindergarten teacher in Jackman were withheld from the public Wednesday, despite a request by the district attorney’s office and the press.

Judge Roland Cole denied a request in Somerset County Superior Court to unseal the arrest affidavit on the case of Rob P. Mocarsky, 41, who is charged with two felonies: sexual exploitation of a minor and possession of sexually explicit materials.

The affidavit likely contains in-depth information about why police had grounds to arrest Mocarsky. An affidavit must show probable cause that a crime has been committed and is, in most cases, made public once the person in question has been arrested.

After Mocarsky’s arrest in January, Judge Peter Darvin kept the affidavit confidential, saying he wanted to protect the investigation. He indicated no timeline for making the affidavit public.

Assistant District Attorney Brent Davis later filed a motion to lift the impoundment, after the Morning Sentinel asked the district attorney’s office to do so.

Defense attorney Robert Sandy Jr. argued Wednesday morning, in a five-minute court hearing, that he was never served the paperwork.

He said he could not argue whether the affidavit should be released because he hadn’t seen it. It may include factual errors, he said, and cause undue media attention.

District Attorney Evert Fowle said he was just trying to make available a document that is normally public. Its contents had been discussed in court, at Mocarsky’s bail hearing in January, he said, so releasing it would not jeopardize the investigation.

“This matter has already been reported publicly,” he said. Once the affidavit becomes public, people will see “it was not worth the consternation that it’s caused.”

After the hearing, Sandy declined a reporter’s request for a comment from Mocarsky, who did not speak in court.

Mocarsky, who taught at Forest Hills Consolidated School in Jackman, is accused of enticing a girl who was younger than 12 to “engage in sexually explicit conduct” to photograph it, and of possessing pornography of children younger than 12.

Few details about the investigation have been made public, such as whether any of Mocarsky’s students were the subjects of what police said were hundreds of pornographic photos.

Davis told the court in January that the investigation began when a student told her mother that Mocarsky kept her in the classroom after other students had left, told her to dress in a French maid’s costume and took her picture.

Administrators put Mocarsky on administrative leave and contacted Maine State Police on Dec. 8 — the day the mother approached them. The school board accepted his resignation Jan. 25, effective Feb. 19.

He is scheduled to appear in court at 8:30 a.m. April 6.
