The hearing was told that Ava died after being stabbed in the neck during Liverpool city centre's Christmas tree switch-on on Thursday evening. The bright Year 8 pupil had been enjoying the festivities with friends. After she collapsed, a passerby and paramedics tried desperately to save her but she was pronounced dead at Alder Hey Children's Hospital. Yesterday the suspect, who cannot be named due to his age, appeared via videolink at Liverpool Crown Court charged with murder and possession of an offensive weapon.
