He was reported to Prevent at least three times.
Police were involved 4+ times
He was under the care of mental health services.
He was expelled from schools.
He had committed violence before.
He had been found with a knife by police and escorted home with a warning.
These services were not sharing information.
Parents should have rang the police immediately that day. They failed in their duty of care.
In retrospect,
They should have not allowed him on the Internet, no phone etc, from when he went through puberty and first started signs of MH, before he got too big and terrifying to discipline him.
But how many parents let their children have free access to the internet.
This is also how Brianna Ghey's killers lost themselves into evil hateful ideas.
The parents of AR were overwhelmed once he started threatening them.
There was a disabled wheelchair bound child in the house too, that they had to protect.
AR was failed by his parents and all of the above mentioned services.
And this caused the terrible heartbreaking tragic end result of the tiny kids murdered and many more traumatized and hurt.
