Ryan King death: Wine glass 'cut jugular vein'
A man who died after being slashed with a wine glass by his great uncle suffered a severed jugular vein, a jury has been told.
Ryan King, 20, died from loss of blood after the injury at his mother's 40th birthday party in Devon in August 2011.
Raymond Dupree, 68, of Bishop's Nympton, Devon, denies murder.
Exeter Crown Court heard he and Mr King were among 30 guests at Snurridge Manor House in South Molton when a row about the volume of music led to the injury.
Mr Dupree claims the stabbing was an accident, but the prosecution has said Mr King was attacked when he tried to stop his "angry" uncle bullying a group of young teenage girls who were were still playing music at 03:00 BST.
Home Office pathologist Dr Amanda Jeffery said: "The cause of death was an incised wound on the left hand side of his neck.
"He died predominantly through blood loss. The injury had gone into the deep structures of his neck and clipped the left internal jugular vein, causing significant blood loss."
Former boxer Mr Dupree also suffered an injury to his hand, probably caused by fragments of the glass as it broke, the court was told.
The case continues.
