A man fighting for life after a head-on crash on a Queensland highway that claimed the lives of four people has suffered a series of horrific injuries — including rupturing the largest artery in the human body. Jonathan Green, 27, and his friend, 28, were in a Toyota Hilux that was hit head-on by a Holden Commodore on the Capricorn Hwy, between Comet and Blackwater in the state’s Central Highlands, just before 11am on Sunday.
