The driver who hit Paire stopped at the scene and is still cooperating with investigators.

Dudley-Charlton Regional School District Superintendent Gregg Desto confirmed in a letter to the community that Paire, a longtime Dudley Middle School administrator and current Charlton Middle School teacher, was the victim in the crash.

“John was one of the true champions of the ‘students first’ philosophy that permeates our district,” Desto wrote. “Every decision he made was with the best interest of the kids in mind.”

Desto described Paire as a “rare leader” who was passionate about in and out of the school community.

“Our district is undoubtedly a lesser place for his passing, but I knew John well enough to know that he would not want us to just sit around and be sad,” Desto wrote. “He and I navigated many difficult situations together, and I know he would want us, first and foremost, to take care of our students and one another.”

Several Dudley and Charlton schools will be open on Sunday for community members to gather and grieve.

In addition, counselors will be on hand Monday and Tuesday in school libraries for students and staff.
