Jurors in the Ava White murder trial will have to put aside "sympathy" and "emotions", a judge said today.
The trial over the death of the 12-year-old formally began at Liverpool Crown Court this morning. A 14-year-old boy, who cannot be named for legal reasons, denies her murder.
Ava died on Thursday, November 25 last year after visiting Liverpool city centre with friends to watch the Christmas lights switch-on. Police said she was involved in a "verbal argument" in Church Alley, which escalated into an "assault on her with a knife", at around 8.35pm.
