A woman who went looking for her missing sister unsuspectingly helped her sibling's unresponsive killer just minutes after he ploughed into her in a horrific hit and run collision.
Late on October 17, 2020, a worried Chenai Radnedge went looking for her sister Tammara Macrokanis, 32, who had stormed out of a family gathering in the Gold Coast's northern suburbs.
Her search though was held up when she stopped to help a man lying on the ground next to his car on the shoulder of the M1 highway.
Ms Radnedge at that point had no clue the man she was calling triple-zero for was Kaine Andrew Carter, who minutes earlier had fatally struck her sister while under the influence of drugs and dragged her body 60m down a highway.
Tammara Macrokanis, 32, was walking down the M1 Pacific Motorway, near Coomera on the Gold Coast, when she was struck and killed by a drugged-up driver

The impact was so savage it tore her sister's body in half, The Courier Mail reported.
But when Ms Radnedge bent down to help Carter at 9.30pm that night, she had no idea what had happened to Ms Macrokanis - a mother of five and recovering drug user who had turned her life around.
All she knew was her sister left the family gathering after taking offence to a misunderstanding and threatened to hitchhike back home to New South Wales.
Just as Ms Radnedge was trying to help the drugged Carter beside the M1, several Queensland police cars arrived.
They had been alerted to a car parked in a dangerous spot near an exit on the M1.
Ms Radnedge didn't notice the damage to Carter's ute - and the amount of blood and 'body matter' smeared across it.
