The trial has this week got underway into the murder of Owen Dunn from Swindon.
On December 4th, 2022, the 18-year-old was fatally stabbed in Mazurek Way, Haydon End.
Tyler Hunt, 18, of Park South, and a 15-year-old who cannot be named for legal reasons, have been charged with his murder, which they both deny.
The pair have pleaded guilty to being in possession of a knife, and admit to being at the scene, but say they were acting in self-defence.
The trial, taking place at Bristol Crown Court, is expected to last three weeks.
