An old friend seems to be experiencing some kind of mental health episode. A month or so ago, she started sending strange Facebook messages and emails to our group of friends.  It was mostly centered around her feeling like we were "defaming" her, and then began targeting one member of the group and his wife, saying he was an addict, abusive, etc.  She claims to be working on a project where she can only communicate using telepathy and clairvoyance.

More recently, her emails are only to me an one or two other people and have contained an address (we think is her parents), a set of coordinates that are in the forest in Big Sur, and then a set of coordinates in Oregon with the text "the two girls can be found here".  Today I received an email about "victims" with exceptionally graphic descriptions of young girls in San Diego being raped, murdered, and....eaten.

This girl has changed her phone number and no one knows where she's living.  Her family says that are worried but haven't been able to get in touch with her.  I talked to the police before I got this last email, and they said nothing can be done unless she threatens to harm herself or others.

I'm fairly confident these stories are made up, but I'd like to make sure there's no truth to them and I also want to get my friend the help she needs.  Any advice would be appreciated.
