DUXBURY (CBS) – Investigators say photos of up to 50 Duxbury High School girls in “varying degrees of undress” were found in a Dropbox page, which has been shut down.

Authorities say there is no indication that any of the students had photos taken of them in an unsuspecting way. Police say some photos are real, while others appear to be fake.

Duxbury Police Chief Matthew Clancy says many of the photos appear to be selfies.

“At the end of the day, these are children and they’ve made a mistake,” he said at a news conference on Friday.

Dropbox has been contacted by police and served a search warrant for further forensic testing. Clancy was the West Coast company has been cooperative during the investigation.

“Essentially, our goal is to go after the source, the individual (who) created this site,” Clancy said.

School officials say it’s been an embarrassing and sensitive lesson for students.

“We would hope that our young girls understand that there are other ways to be popular,” said Duxbury Schools Superintendent Dr. Ben Tantillo during the conference.

Tantillo added, “We want our kids to be safe, (and) we want our boys to know that this is not an appropriate way to treat women.”

Clancy says he has no plans of levying criminal charges in the case. He wants the matter to be more of a life lesson for students, and educational forums are already in the works at the school.
