A Quincy High School varsity cheer coach is being investigated for allegedly providing alcohol and marijuana to students while committing other alarming crimes, according to the district’s superintendent.

In a letter sent to the school community on Friday, Superintendent Kevin Mulvey did not name the coach subject to the district-led investigation into alleged “violations of state and federal law,” The Patriot Ledger first reported.

“Specifically,” Mulvey wrote, “it is alleged that on at least one occasion, the employee provided alcohol and marijuana to Quincy High School students, shared inappropriate images online, and breached student confidentiality by sharing private information that the employee had access to in the course of their administrative responsibilities.”

The superintendent called the allegations “very serious,” adding that the employee has been placed on administrative leave amid the active investigation. He did not describe the “inappropriate images” or say whether law enforcement is also investigating.

“Not all of the details are currently known to the school department,” Mulvey wrote in his letter. “I would like to thank the members of the school community who brought these incidents to the attention of school and district administrators.”
