The Teeswide Safeguarding Adults Board and Hartlepool Safeguarding Children Board have explained the details of the independent multi-agency reviews which will be undertaken following the Angela Wrightson murder trial.
A statement from the board read: "In accordance with a request from the Crown Prosecution Service, the reviews could not start until after the trial was concluded, but have been planned for some time.
"Two Hartlepool teenagers – 13 and 14-year-old at the time - were found guilty of Angela Wrightson’s murder at Leeds Crown Court on Tuesday 5 April 2016.
"An independent Safeguarding Adult Review is being undertaken by the Teeswide Safeguarding Adults Board regarding Angela Wrightson and independent Serious Case Reviews are being undertaken by the Hartlepool Safeguarding Children Board regarding the two teenagers.
"Both Boards have commissioned the independent reviews on behalf of all of the agencies involved.
"Deborah Jeremiah will lead the Safeguarding Adult Review into Angela Wrightson whilst Jane Wiffin will lead the Serious Case Reviews into both teenagers. They are, however, working together to undertake the three reviews to make sure that the maximum amount of learning is realised.
"Both individuals work nationally and are independent of the local area. They are experienced independent reviewers are fully trained in the review methodology recommended by the Government.
"Both reviewers will also be assisted by national experts including in mental health and child criminology."
Ann Baxter, independent Chair of the Teeswide Safeguarding Adults Board, said: "This is a tragedy for everyone involved and the Safeguarding Adult Review will consider all the circumstances leading up to Angela Wrightson’s murder.
"Deborah Jeremiah is a leading expert in her field and I am sure that she will leave no stone unturned in identifying whether any lessons can be learnt by any of the agencies involved.”
Dave Pickard, independent Chair of the Hartlepool Safeguarding Children Board, said: "The purpose of the Serious Case Reviews is to determine whether the actions taken by the teenagers, leading to Angela’s tragic murder, could have been prevented by the agencies who were involved with the teenagers.
"The Hartlepool Safeguarding Children Board will also ensure that, if it becomes evident from the reviews that lessons need to be learnt, those agencies act upon them.
"Events like this are extremely rare and we owe it to Angela to learn everything we can and, where necessary, share those lessons nationally.
"Jane Wiffin is a leading national voice in children’s safeguarding, who has undertaken a number of previous reviews, and we look forward to receiving her findings.”
The reports will be made public at a later date.
