After the truck hit the officers, Pusey filmed them for several minutes with vulgar commentary as they lay dying, before fleeing.

[3] Victoria police commissioner Graham Ashton stated that two officers stopped a Porsche 911 that had been travelling at 140 km/h around 5pm on 22 April, a Wednesday afternoon.

[5] Singh, 48, was sleep deprived and high on drugs when he crashed his 19-tonne semi-trailer into the officers who had pulled over Porsche driver Richard Pusey.

An oral drug test on Pusey confirmed he had MDMA and cannabis in his system and the officers called for backup to impound his car.

About a minute after their arrival, the four were standing in the emergency lane while Pusey urinated off the side of the road when Singh's truck struck them.

Pusey continued vulgar commentary while filming for more than three minutes before fleeing on foot and sharing the video on Facebook.

He was charged with two counts of perverting the course of justice, driving at a dangerous speed, reckless conduct endangering life, destruction of evidence, and not providing assistance after an incident.

[9] After an 18-month investigation, the truck company Connect Logistics was charged with category one and two offences under heavy vehicle national law.

The police allege that Tuteru should have not allowed Singh to drive on the day of the accident due to his fatigue.

In a news conference, Australian Prime Minister Scott Morrison thanked Victoria police, whilst offering his condolences.
