A 19-year-old Jack McAllister died from loss of blood after suffering 14 stab wounds, including one which severed a major artery, the Invercargill High Court was told on Thursday.
Christopher Brown (20), Laura Scheepers (19), Natasha Ruffell (27), David Wilson (20), and a 24-year-old woman with name suppression, are standing trial at the High Court, Invercargill, all facing a single charge of murdering McAllister.
Crown lawyer Riki Donnelly, in the opening address to the jury, said while none of the five defendants was physically involved in the stabbing, each had played their part.
Brayden Whiting-Roff, who has previously pleaded guilty to McAllister's murder, was the principal offender, Donnelly said.
McAllister, also known as Jade Fearn, died from injuries sustained during an attack at Stadium Southland on June 7 last year.
