The jury in the Ava White murder trial has retired to consider its verdicts.
Ava, 12, was stabbed in the neck in Liverpool city centre last November. A 14-year-old boy, who cannot be named for legal reasons, denies her murder and manslaughter in a trial at Liverpool Crown Court.
Prosecutors say Boy A, from South Liverpool, knifed Ava after she argued with the teen about him filming her on Snapchat. They allege he laughed and ran away after stabbing her in the neck, then ditched his flick knife, designer coat and mobile phone in a "cover up", and told lies to police including giving a "false alibi" and suggesting another boy was responsible for her fatal injury.
