Two men have been arrested in Australia's Sydney, after a high-speed crash that killed two teenagers.
CCTV captured the violent impact that split the car in two, and the men abandoning their dead passengers.
To hear the shrieking engine as it speeds along a suburban road is one thing, and watching it split in half is another.
But what happens next is even harder to comprehend.
As a trail bike following the car arrives, one man walks away from the wreckage.
He walks to the rear of the car, undoes a boy's seatbelt, and seeing he's dead, drops him to the ground.
Returning to the front, a second survivor emerges.
They don't stay long at the scene, slowly stumbling off past the body of a second child, who was thrown from the car.
They also ignored a witness who arrived and was calling for help.
"When you've caused that much carnage and you don't stick around to take responsibility for it, it's a weakness of character," said Brett Mcfadden, assistant police commissioner for New South Wales.
The manhunt lasted just 24 hours.
The two men in their 20s were arrested and charged on Tuesday.
The two boys they allegedly drove to their deaths were just 13 and 14 years old.
"This family, from my understanding the drivers, took in these two boys and made them as part of their family," said Ned Mannoun, mayor of Liverpool.
"So they looked up to them. They were like little brothers to them. For whatever reason they were out there trying to be together as one," he added.
Instead, they were ripped apart in a matter of seconds.
