For two young teenagers the night of 8 December 2014 in Hartlepool UK began like many others.

But by the next morning, the two girls would be murderers, having taken their time to batter a Vulnerable woman to death with a variety of weapons.

The attack lasted for 5-7 hours. It was said Angela Wrightson suffered an "absolute minimum of 70 separate slash injuries and 54 separate blunt-force injuries".

The girls were aged 13 and 14 when they put 39-year-old Angela Wrightson through this ordeal while posing for Snapchat selfies.
