12-year-old Ava White's schoolboy killer unmasked on 18th birthday

The teenage boy who murdered 12-year-old Ava White can today be named and pictured for the first time after he turned 18. Harry Gilbertson was just 14 when he stabbed the schoolgirl in the neck following a petty row over a Snapchat video, in November 2021. Following the attack, the teenager ran away, leaving Ava - who had been in Liverpool city centre with friends to watch the Christmas lights switch-on - bleeding to death on the pavement.
