CLEVELAND — A teacher wounded in a shooting rampage at a downtown high school said Monday that the student gunman was disruptive and was failing the teacher's world history class.

Michael Grassie, 42, spoke at MetroHealth Medical Center before his discharge. He was wounded in the abdomen last week by Asa Coon, 14, who killed himself after wounding a second teacher and two students.

Grassie, sitting in a wheelchair, said Coon was doing poorly in his class at SuccessTech Academy and risked failing.

"I know that made him really mad," he said. "He just seemed really troubled, really troubled."
