Jeff the Killer (origin story rewrite)

This is basically Jeff's origin story but I'm rewriting to make it more "realistic" and basically a better version. I will be changing a lot of things in the story, but only to make it feel more realistic (like his age, why he went psychotic, blah blah blah)

The Woods family have always had their issues, the main one being their 16 year old son Jeff, who has always been a bit, different. After a incident happens where Jeff attacks one of his former classmates, this time landing the kid in the hospital, his family decides to move, hoping a new scene will help Jeff. Only things take a turn for the worst, as Liu, Jeff's older brother starts noticing his little brother acting stranger then usual..
