These six people were at a rave, and when Jason Voorhees appeared, he killed Gibb Smith, Frisell, Shack's friend, Shack, and the ravers. The corpses have been found and taken away to a morgue by police and paramedics and they all had their pictures taken. All of their bodies are buried at their funerals later on.
They are Jason's 141st through 146th confirmed murder victims.
