A teenage girl is now facing murder charges, after a man who was allegedly stabbed in Adelaide's north this week died in hospital.
Police had originally charged the 16-year-old girl with attempted murder, but this morning said those charges would be upgraded to murder.
Police said they had responded to reports of a domestic assault at a home on Petherton Road in Andrews Farm in the early hours of Monday morning and found a 55-year-old man with stab wounds.
Police said he was rushed to the Royal Adelaide Hospital with life-threatening injuries but he died last night.
The 16-year-old girl, who police say was known to the man, will appear in the Adelaide Youth Court today.

Meanwhile, two people have died following a crash at Lochiel, in the state's Mid North, last night.
Police said emergency services were called to the Augusta Highway at 7:30pm on Tuesday after a car travelling north left the road and crashed into a tree.
The 19-year-old male driver and a 17-year-old female passenger, both from Port Pirie, died at the scene.
The front passenger, a 46-year-old Port Pirie man, was airlifted to Royal Adelaide Hospital with serious injuries. He succumbed to his injuries and died on December 30.
The Augusta Highway was closed for several hours while Major Crash Officers examined the scene. It has reopened.
