The suspect was contained in a home nearby. Police confirmed the person took their own life.
Rochester Hills is about 15 miles (24 kilometres) south of Oxford, where in 2021 a 15-year-old fatally shot four high school students.
Saturday’s shooting came at the end of the first full week of summer vacation for students attending Rochester community schools.
Mr Bouchard called it “a gut punch” for the county.
“We’ve gone through so many tragedies,” Mr Bouchard said. “We’re not even fully comprehending what happened at Oxford. And, you know, now we have another complete tragedy that we’re dealing with.”
Michigan Governor Gretchen Whitmer said on X, formerly Twitter, that she was heartbroken to learn of the shooting and was in touch with local officials.
