That is so vague ...... I mean, you could read into it that one teen did something to cause anaphylaxis in a food allergic classmate, and they ended up dying. That is how I take it. But, there are no real details. I think there needs to be a lot more to that story.... and will be interested in knowing how things develop.
If indeed it turns out that the facts come out and it is that way, then I also will be interested to see how things are prosecuted and sentenced.
