Police: Angela Wrightson case 'highly unusual'

This was a highly unusual and shocking incident. Throughout almost 25 years of service I have never come across such a brutal murder committed by such young girls.

Angela was subjected to a prolonged, sustained attack and the pathologist identified a significant number of injuries to her body caused by at least 25 blows with weapons...

In my experience this is an almost unique investigation in terms of the age of the offenders and the fact that they are girls.

Many questions remain unanswered about the motive for the murder but the family of Angela who have had to endure the most shocking and traumatic details unfolding over the last few weeks will get some satisfaction from knowing that her killers have now been convicted of the killing.
