The man convicted over a brutal assault on two young female backpackers at Salt Creek, in South Australia’s Coorong region, has lost his bid to prevent his vehicle from being destroyed.

Roman Heinze was found guilty in the Supreme Court of six offences over the 2016 attack, including aggravated kidnapping, endangering life and indecent assault.

He is now six years into his 22-year sentence.

Earlier this month, Heinze appealed to the Supreme Court to reverse a magistrate’s ruling to destroy his vehicle, which he used in the attack.

During his criminal trial, a jury heard Heinze hit one of the victims with a hammer and pursued her in his four-wheel-drive, using the bull bar as a battering ram.

He previously told the court he denied running over one of the victims and argued he needed the vehicle for DNA evidence to assist in a future appeal of his case.
