The alleged driver of a car involved in a fatal hit and run crash in Adelaide's South has been urged to hand himself in.
Police want to speak with 22-year-old Michael Henley in relation to the crash at Morphett Vale.
They have already arrested a passenger from one of the cars, a 19-year-old man who has been charged with manslaughter, causing death by dangerous driving and impeding an investigation.
He has been refused bail and will appear in Christies Beach Magistrates Court on Thursday.
On Tuesday night a Ford sedan and a white Toyota Hilux collided with a 20-year-old passenger in the Toyota dying at the scene.
The 22-year-old driver of the Toyota was taken to hospital and treated for non-life threatening injuries.
The Ford failed to stop and was later located burnt out in a gully off the Southern Expressway at nearby Reynella.
The crash came after SA was placed in a full lockdown because of an outbreak of COVID-19.
Tuesday night's death took the SA road toll to 58 compared with 52 at the same time last year.
Police have called on Mr Henley to come forward and have asked anyone who knows of his whereabouts to contact detectives.
