Police allege Kokozian fled the scene after crashing while travelling at nearly double the speed limit for the 50km/h zone.

His father Kagadour Hanna Kokozian faced Liverpool Local Court on Thursday charged with concealing an indictable offence and hindering a police operation.

Police allege the father and son, together with Johnson’s 22-year-old girlfriend Tiana Savignano, discussed a cover story and made false reports to investigators following the crash.

Savignano has also been charged with concealing a serious indictable offence and hindering the police investigation.

Kokozian’s friend Cruz Pamoana Davis-Tuka and another woman, Laila Moukhallaletti, have also been charged with helping to conceal the crime.

Earlier this month, Savignano pleaded guilty to filming her boyfriend during a Parramatta Local Court bail hearing on September 3 as he faced one charge of aggravated dangerous driving occasioning death.

She will be sentenced over the illegal filming incident on November 27.

Johnson and Kagadour Kokozian, along with Savignano, Davis-Tuka and Moukhallaletti, will all come before Campbelltown Local Court on November 1 for a mention over charges relating to the Heckenberg crash.
