Someone in the comments on the previous post reminded me that I never did give you the update on My daughter's death threat situation
The youngster in question was brought in to the juvenile authorities by his parents, where he was processed, etc. He goes back to court on the 29th, where he will see a probation officer who assured me that they will recommend psychiatric counseling for the boy. From what I understand via my ex husband, the boy's parents are willing and eager to cooperate with this, as they realize now that their son has anger management issues.
We chose not to seek an order of protection as a) we are confident that the parents of the boy are keeping him under careful watch and b) we didn't want to make Nat go through the process of having to appear in court to testify against her former friend.
Really, all we wanted was to make sure the kid got some help. Apparently, he's a very good student and, aside from the death threat thing, not a bad kid. I think with some guidance and professional help he can overcome whatever issues are making him behave this way.
So, hopefully, end of story. Thank you to everyone who offered advice and support.
