LITCHFIELD — Police are investigating the sale of marijuana-laced brownies at Campbell High School, which has led to the suspension of about 10 students.

According to superintendent Brian Cochrane, a teacher noticed some type of odd activity inside a student’s vehicle parked at the school on Sept. 26. Faculty determined that one student was allegedly selling hash brownies to other students, and the local police department was immediately notified, said Cochrane.

The brownies were made off school grounds and brought to the high school parking lot where they were being sold and distributed, Cochrane said. He also said the brownies were confiscated and are now being held as evidence.

A small number of brownies were either sold or pre-sold before a container of about 20 brownies was seized, according to the superintendent.

In addition to the student who was selling the brownies, about eight to 10 students had some other type of involvement, said Cochrane, explaining some of the students purchased and received a brownie, some paid $10 for a brownie but never received it, and others obtained the brownie off school property.

Some students received a 10-day suspension if they possessed or admitted to possessing a marijuana-laced brownie on school grounds, according to Cochrane.

In addition, some students involved are school athletes and were punished according to the district’s athletic policies.

“The policies were all applied equally. But in this case, you have an agreement with your athletes to be held to certain standards,” he said. As a result, any of the student athletes involved with the brownie sale were suspended from playing their sport for a quarter of the season, said Cochrane.

He explained the athletes will be able to return to their team — if time permits — once they complete necessary community service and education requirements. Some of the sports seasons may conclude by the time the students are allowed to return, and other teams may have a little playing time remaining, he said.

“The students themselves were very open and very cooperative,” said Cochrane. “And I think they were very disappointed in themselves.”

He said school administrators handled the situation thoroughly, and now it has been forwarded to the Litchfield Police Department.

Police Chief Joseph O’Brion was not immediately available to comment on the matter.
