ROCKPORT — A former educational technician at Camden-Rockport Elementary School pleaded guilty Monday to bringing a loaded gun to school.

But under terms of an agreement reached with the Knox County District Attorney’s Office, the charge against Meaghan M. Collier, 23, of Tenants Harbor, will be dismissed in 12 months if she adheres to terms of the deal.

Collier pleaded guilty Monday in Knox County Unified Court to Class E misdemeanor possession of a firearm on school property.

The charge against Collier will be dismissed in December 2017 if she refrains from further criminal conduct, completes 50 hours of community service work and pays a supervision fee of $10 per month.

If she violates the deferred disposition, Collier would be convicted of the charge and fined $200.

Assistant District Attorney Jeffrey Baroody said Collier had carried the gun with her early in the morning when she was walking her dog and said she had forgotten she had it and had no intention to bring it to school.

Baroody called the action “extreme negligence.”

Collier did not have an attorney and represented herself in negotiations with the prosecution.

Collier was issued a summons Oct. 28 by Rockport police on the day of the incident.

Police said a loaded Glock .380-caliber handgun fell out of her lunch bag, which was in the refrigerator at the staff lounge at the school. The lunch bag fell out of the refrigerator when another staff member was removing an item.

There was no bullet in the chamber and the weapon did not fire.

Collier had been hired at the beginning of the school year to be a one-on-one technician in the Explorers Program for an autistic student.

She resigned from her job shortly after the incident.

Camden and Rockport Police Chief Randy Gagne had said Collier had no ill intentions, but simply had forgotten the gun. He said it was a case of not following safe gun-handling measures.
