A teenage killer has been jailed for the murder of schoolgirl Ava White who was stabbed to death at a Christmas light switch on.
The 14-year-old boy launched a 7.5-inch flick blade into Ava's neck when an argument broke out over a Snapchat video in November 2021.
The killer, who cannot be named for legal reasons, and 12-year-old Ava had both attended the event separately in Liverpool city centre when the festive evening ended in a murder probe.
