The girlfriend of a man accused of killing a brother and sister in a high-speed crash has been hit with further charges after police investigated her for helping to cover up the crime.
Tiana Savignano, 22, has been issued a court attendance notice for 31 driving offences unrelated to the deadly crash, including speeding, drink driving, using a mobile phone while driving and having an unrestrained child in the car.
On Monday, police revealed she has also been charged with illegally filming part of a court hearing.
Savignano's partner Johnson Kokozian, 20, was allegedly behind the wheel of a speeding Mercedes SUV that smashed head-on into a car containing siblings Alina Kauffman, 24, and Ernesto Salazar, 15, in southwest Sydney earlier this month.
Both of the siblings were killed in the Heckenberg crash.
Savignano was initially arrested and charged after turning up at court to support Kokozian.
Police allege that she, Kokozian and his father discussed a cover story and made false reports to investigators.
In the process of investigating Savignano for hindering the police investigation, officers also uncovered evidence to charge her with the additional offences.
Five people have been charged in relation to the deadly crash, including Kokozian's 61-year-old father.
Savignano is due to appear at Liverpool Local Court on Tuesday.
