A 17-year-old girl who jumped from a moving car in Brisbane's south last week during a fight with her brother has died in hospital.
Carmen Pua was in the back of her brother Kevin's car as it travelled along Progress Road in Richlands last Wednesday when a fight erupted between the pair about 10.30pm.
Mr Pua told 7 News Queensland in an unexpected move, his sister jumped from the back of his car.

"We just had a brother and sister talk, I give her a bit of a lecture, she didn't want to listen no more," Mr Pua said.
The teenager, from Durack, suffered critical head and chest injuries when she fell onto the roadway.
Paramedics rushed her to Princess Alexandra Hospital, where she clung to life for five days.
She passed away on Monday morning.
