My step-children live in Colorado. I live in Oregon. There are three boys. The oldest has been diagnosed with Aspergers (high functioning Autism and ADHD). He has not be officially declared disabled. The oldest severly and violently attacks his younger siblings. On their last plane flight back to Colorado he held his brothers head against the arm rest and threatened to kill him.
Here's my question, we feel that very little is done by his mother to prevent these "out-bursts" towards his siblings. We know he is in counseling and he is medicated, but it does little to deter him from physically and emotionally beating up on his brothers. What rights do we have to try to get custody of the younger two boys using sibling abuse for the reason?
