Another 20-year-old man, who had been driving in the silver sedan with Mr Murphy, tried to resuscitate him on the roadside. The teens assaulted him before fleeing the scene, police claim.
Mr Murphy was found dead a short time later.
The two 19-year-olds were taken into police custody just before midnight at an address in Atlantic Street, Springfield Lakes.
Mr Vital and Mr McPherson appeared in Ipswich Magistrates Court on Monday, charged with one count each of murder, common assault, enter dwelling and robbery with violence.
Mr Vital’s lawyer Daniel Hannay and Mr McPherson’s lawyer Daniel Hua fronted media afterwards.
“It’s an absolutely tragic set of circumstances,” Mr Hannay said.
“Today as you can see, the family is completely distressed and I’m taking instructions with respect to a bail application.”
When asked whether Mr Murphy’s death was an accident, Mr Hua said it would be a “very bold and foolish thing” for him to ascertain because the allegations were not clear.
“On behalf of my client, he wishes to extend his heartfelt condolences to the victim in this matter,” he said.
“It’s indeed a tragic set of circumstances and at the moment, we’re not clear on what the allegations are, so far as his participation is concerned, so it’s something he’s keen to finalise before the courts in an expeditious manner.
“It’s not known what exactly the case against him is and it’s going to be some time until that comes out so we’re still waiting for a brief of evidence at the moment.”
The teenagers will remain in custody until they reappear in court at November 13.
