I was running a school in PA many years ago - guess it was around the mid-1990's - and I had one student that was a child prodigy.
She was 14 years old and was the most flexible and fast-moving student I've ever had. She picked up on techniques instantly and performed them flawlessly. I began taking her to tournaments where she pretty much won everything in sight.
She came from a broken home with a missing father and an alcoholic, abusive mother, so she spent a lot of time at my school.
One day she didn't show up for class. Okay, maybe she has a cold or something. Two days, still AWOL. Three. Not like her. I begin asking around, drive to her house, mom said she hasn't seen her in a few days (!). Searching, searching, day and night, ready to call the cops.
They found her body in the river beneath a bridge.
Not sure to this day what happened. She would have been 16. Somehow I feel I didn't do enough - if I could change something it would be that.
