Thank God the kids are OK.
Of course the kids are ok. It was a custody issue. He has PTSD for cripes sakes! Losing his kids is akin to losing squad mates in battle. He reacted accordingly for his state of mind. When he was secure with his children his panic subsided and he realizes what he has done. Now he’s outrunning the reality of it and doesn’t want his kids to be involved. His world is spinning all around him. He will soon either turn himself in or commit suicide.
Just my thoughts on it.
