I have said this many times here but I have a dear friend who lost her son to suicide several years ago. He hung himself in his dorm room on Homecoming weekend.
He did not do it on webcam (that I know of) but he was on-line and visiting suicide chat rooms where the topic was discussed and people talked to him about ways to do it, what happens to the body as you do it and are dying etc. They were able to go back in his computer and see a lot of stuff and he'd been crying out for help to the wrong people. They egged him on. So sick. So tragic.
His mom has been missing him for quite awhile now and always will.
This story in the OP, brings all the pain back and the anger also.
What a sick bunch of people.
