SYDNEY, Dec. 23 (Xinhua) -- A police manhunt is underway for two people after a woman was shot dead in Australia's state of Queensland.

The Queensland Police said in a statement on Sunday that they were called to a Railway Parade address at Caboolture, a town about 45 km north of Brisbane, at around 12.10 a.m. on Sunday where they located the woman unconscious and unresponsive. She was declared dead later.

Initial investigations indicate the 23-year-old woman was assaulted by two males and sustained a gunshot wound outside the Railway Parade property.

Detectives believe this is not a random attack and have launched a homicide investigation. ■
