approximately 02:00 on 9 December to continue the attack. Following the attack, the girls left Wrightson on her couch either semiconscious, unconscious, or dead. They left the property at 04:00, and one of the girls texted her carer to come and collect her. With no response, and correctly assuming they would have been reported missing, the girls twice telephoned 999 for a lift home from the police. En route home with the police, the girls posed for a Snapchat photograph with the caption "in the back [of] the bizzie van again". At approximately 08:45 on 9 December, Wrightson's landlord returned to the house to return her keys. He found her body on the couch; she had sustained 103 injuries of which 80 were to her head. Perpetrators At the time of the attack, the girls were aged 13 and 14. Both had experienced physical abuse from their biological parents. The girls were resident in the care system; the elder was living in a children's home and the younger with a foster family. Two months before the murder, the elder girl had been arrested for assault on care home workers. Reviews by two safeguarding bodies, the Teesside Safeguarding Adults Board and the Hartlepool Safeguarding Children Board, reported that both girls engaged in underage drinking and that the younger girl was involved in drug misuse and possible underage sexual activity. The 2017 serious case review reported that the mother of the elder girl was concerned that she was "going to parties, possibly having sexual intercourse" as well as physically assaulting her younger siblings. Legal proceedings Arrests On 9 December, the elder girl spoke to youth workers and expressed an interest in Wrightson's death as well as prison sentences for murder. The younger girl spoke to friends and was reported to be "quiet and shaking"; she too seemed interested in the case and sent a text message to one friend saying "I might be getting sent down". Cleveland Police launched a murder investigation and both girls were arrested the same day. Trials and convictions Both minors at the time of the offence, the identity of the two teenage girls is protected by the Children and Young Persons Act 1933. The first trial began in July 2015 at Teesside Crown Court in Middlesbrough, although Justice Henry Globe soon ended the trial when information about the defendants was disclosed and shared on social media.
