Prosecutor Aaron Perkins said the victim was assaulted at an unknown location and bundled into the boot of Permal's mother's car, driven by Kumar.
The defendants then allegedly bought 15 litres of petrol, using the stolen life savings, before driving to McRobbie Rd in Kingseat, where they doused the victim in petrol and set him alight.
Medical witnesses gave evidence that Mr Prasad was alive when the fire was ignited but there was some contention over his consciousness.
The Crown said there was a possibility he was kneeling, sitting or standing when covered in the accelerant but defence lawyers said the evidence clearly pointed to him lying on his back in a state of "deep unconsciousness".
Kumar's defence counsel Ron Mansfield hit back at allegations yesterday during his closing and said Mr Prasad's death may have been accidental.
He said there was "a vacuum of evidence" to support the contention his client had intentionally killed the victim and the Crown lacked the requisite evidence to prove murderous intent.
"Not only is there no evidence of an unlawful act, there's certainly no evidence of what unlawful act caused Mr Prasad to be unconscious; let alone who did it, let alone where," he said.
He conceded the burning of the body was "reprehensible" but said Kumar thought his friend was dead at the time.
"A dishonest person doesn't make a murderer."
Mr Perkins argued the evidence suggested Mr Prasad's death was anything but accidental.
He highlighted the defendants' spending spree in the days after the death, during which they allegedly spent thousands of dollars of the victim's life savings on tattoos, clothes and jewellery.
Kumar also tried to change the number plate on his car and arrange a trip to South Africa, Mr Perkins said.
