Dwyer says it started when a high schooler got suspended earlier in the day, Monday. Then, some communication between two groups at the school led to a meeting in the parking lot at the end of the day.
It was dismissal time at Michigan Collegiate High School when dozens of students were outside waiting to catch the bus when a young man pulled out a semiautomatic weapon and started firing in the air.
Several school buses were loaded with students at the time of the shooting, police said. No one was hurt and investigators say the suspected shooter is not a student.
