Leeds City Council announced today that it has launched an inquiry into Jordan Burling's death to see if "lessons need to be learned" over the tragedy.
During the trial jurors heard Jordan had a very troubled life but only had minimal contact with state agencies, including the education system.

Prosecutor Nicholas Lumley QC told Leeds Crown Court: "We do not pretend that Jordan Burling had an especially healthy or happy life, even in his early years."
The court heard that he attended his local primary school, where he soiled himself and defecated on the floor.
Teachers noted he had head lice and his teeth were in a very poor state.
Soon after he went to Farnley Park High School, his mother wrote to the council telling them that he was going to be educated at home.
He was "home-schooled" from the age of 12, jurors were told.

"He never attended school or college again, never took any examinations or achieved any qualifications," Mr Lumley said.
"Nor did he ever work, as far as can be ascertained.
"From the time Jordan was taken out of school, he became increasingly anonymous. Education and social services played little part in his life."
The jury was told that Jordan had not been seen by the family doctor for years before he died.
And he had not seen a dentist since 2009, when 16 of his teeth were treated, including four extractions.
Mr Lumley said: "He only really had contact with his immediate family.
"He may have been invisible to the authorities but not so to these defendants."

James Rogers, chair of the Safer Leeds Executive (Community Safety Partnership), said on behalf of Safer Leeds, the Leeds Safeguarding Children Partnership and the Leeds
Safeguarding Adults Board: “Although today’s verdict can in no way compensate for the loss of Jordan’s life and the tragic abuse and neglect he suffered in the months leading up to his death, it is right that the individuals responsible for causing his distress and eventual death have been brought to justice.
“The details which have been emerging in court over the past few weeks of the suffering caused to Jordan by his mother and grandmother and allowed to happen by his sister have made for very difficult hearing, and it is right that those responsible for this crime have been held accountable.
“When we became aware of Jordan’s shocking death we commissioned a full independent joint review which is underway to identify and examine any lessons that need to be learned to try and ensure this cannot happen again in future.
"We will therefore not be able to comment further until we have the outcome of that review.”
