Thank you everyone. Sorry about the avatar

court called and rescheduled for April 16th. I was hoping it would be over today. For hours I felt like puking waiting for the time to come. Now we get to do it all over again.
Hi Kinpa4 - Coming in to this conversation late, but after reading how anxious you were about the court date, I wanted to ask you; does your court system have a victim's advocate office? If it does I would highly suggest getting in contact with them.
When I had to go to court and testify about a case involving my daughter the advocate assigned to me was a wonderful source of information, and support (my daughter did not have to testify as the perpetrator plead guilty, but I was requested by the prosecutor to speak at the sentencing hearing). Anyway, they were extremely helpful to me, and I believe they would be beneficial if available for yourself, and your son, especially.
I also wanted to ask if the prosecutor(s)/DA know that your son as Asperger's? And, if they knew this when they charged the other boy as well? In some jurisdictions if the victim has a disability of that sort the penalties can be more serious. Even if that's not the case in regard to different charges, it's still important that the DA know about your son's condition. The DA could advise the judge, and everyone can be on the same page as far as knowing your son's limitations, and likely "performance" in a court room. If you are afraid, for instance, that he will have a hard time speaking in front of a lot of people they can clear the courtroom of any observers, etc... Steps can be taken to ease your son of some of the anxiety if they know about his condition.
Anyway, I'm glad you got someone to take this seriously and file actual charges. Honestly, the school systems aren't able to take care of these kinds of situations and keep our children safe. It's not always a matter of not wanting to, but a matter of having to follow certain guidelines to make sure the other child still has access to school, and has their privacy protected - and yes, trust me, I know how incredibly unfair that feels to the victim, and to their parents as well. It's just not right that it is up to the victim to change schools, and other things when it is (in this case) the bully who really should be the one that suffers. It's like everything is backwards when dealing with juvenile offenders...
Again, I strongly suggest getting in touch with a victim's advocate either through the court system, or perhaps through a community advocacy agency that can help guide you through the court process, answer questions and provide support to you and your son.
One more question, if I may, did the girl who was threatened tell on the boy as well, and does the DA know about that interaction also? Are they going to call in the girls as witnesses for the case? Regardless, it's important to tell the prosecutor(s) about the girl being threatened with assault too, as that is witness intimidation, and it's a serious crime in and of itself.
I will keep you and your son in my thoughts and prayers. Prayers also for your other child. After my oldest daughter's experiences (too long to detail here) we opted to homeschool all of our children, but I realize that isn't always an option, or even the best option for some children and families, for many different reasons...
