Police allege that in the days after Friday’s crash, Savignano, a mother-of-one, tried to destroy evidence which showed Johnson Kokozian, 20, was behind the wheel of a black Mercedes Benz SUV when it struck the other vehicle head-on just before 9.30pm.

Kokozian, who has been charged with two counts of dangerous driving causing death and refused bail, denied in court on Sunday that he was the driver, instead insisting he was the front seat passenger.

But police allege Kokozian had taken his father’s $200,000 SUV and, together with two mates, was skylarking around the suburb when he crossed to the wrong side of Sadlier Ave and hit the Kauffman’s car, killing the siblings.

The court heard that Kokozian, a suspended driver, fled the scene in another vehicle without checking on the dying occupants of the car he allegedly hit.

He was seen later that night on social media video eating KFC chicken and chips and joking with a mate, before handing himself into police.

A 61-year-old man, believed to be Kokozian’s father, was arrested in Cartwright at 12.30pm on Wednesday and was taken to Liverpool Police Station where he was assisting police with inquiries.
