I have some mixed fillings on this...
First, only one side of the story has been told... the accused was not found guilty in a court of law.
Life, with all its difficulties, is so precious that I don't understand why someone would chose to end it... unless he/she sees absolutely no other way out.
Although I don't know anybody involved in this case, I'll refrain from passing any judgement, out of respect for the families, friends, students, etc. of both the student and the instructor.
