A PROBE into the death of an Oxfordshire boy who was killed by his own mother has been launched.

Mother Emma Jackson stabbed five-year-old son Tyler Warmington to death at their Faringdon home in March last year.

The 41-year-old paranoid schizophrenic was told by an Oxford Crown Court judge in April she would be held indefinitely in a mental health hospital.

Now, Oxfordshire Safeguarding Children’s Board has confirmed it has commissioned a serious case review into the death.

Such reviews take place where abuse or neglect is thought to have contributed to a child’s death or serious injury.

Authorities had removed Tyler from his mother's care after a mental health episode in 2015, however the boy was returned when Jackson's condition appeared to improve.

A sentencing hearing at Oxford Crown Court heard in April that fears over Tyler’s wellbeing were again raised in spring 2017 when staff at his school noticed that he was absent for two days in a row.

A staff member who visited the boy’s home became suspicious after spotting movement behind a pair of net curtains and called police.

When Jackson opened the door she was covered in blood and had various wounds on her neck and wrists.

The boy had been stabbed 13 times to his chest and back.

Jackson was sentenced under the Mental Health Act to an indefinite period of detention in hospital while she undergoes treatment and cannot be released from hospital until permitted by a mental health tribunal.
