My eldest showed me a status written by my youngest daughters friend it was a screen shot of a conversation between my youngest and her friend where my daughter had said some horrible stuff and even wishing her friend DEAD

Well has you can imagine this status is out there for all to see and she has had all sorts of comeback from it some of them threatning.
Anyone who knows my youngest would be in shock just thinking she could say such things she's more likely to say something soppy than to wish harm on anyone add to that the fact she's nearly lost me a few times the thought of anyone dying scares the crap out of her.
So to my mind and I'm obviously going to say this someone has said these nasty things, hacked account is my guess but it's someone that knows both girls so how do we deal with this? the school says it's a police matter anything that happens outside of school so do i just leave them deal with it?
