A Sarnia teacher helped save a suicidal teenage who was literally on the edge.

He's been hailed as a hero by many, but he remains humble.

Bill Reid has been teaching for 20 years, but nothing prepared the St. Christopher High School gym teacher him for what he came across a week and a half ago.

"I was stressed out, I'm not Superman or anything like that," says Reid.

Reid was driving across the Indian Road overpass in Sarnia when he saw a young girl straddling the guardrail.

Within seconds he knew that he had to do something.

"I asked her what sports she was into, what kind of music she liked," says Reid.

While talking to the girl, Reid covertly called 911 for help, emergency crews arrived and tactically grabbed the girl and brought her to safety.

"It's solely about her and how precious life is. I'm getting goosebumps just thinking about it. I was really only thinking about her," says Reid.

The Lambton Mental Health Crisis Line Centre deals with these kinds of situations all the time.

Management says Reid handled it like a pro.

"What he did for that young person, was miraculous, it was wonderful," says Patti Lauzon with the Canadian Mental Health Association.
