UPDATE: Police believe Goondiwindi mother-of-three Alexis Jeffery was attacked near the location where her body was found on Sunday.
Regional crime coordinator for southern region Detective Superintendent Dave Isherwood said homicide detectives were among those officers trying to determine what happened to Ms Jeffery on the banks of the Macintyre River.
Det. Supt Isherwood has detailed Ms Jeffery's movements on Saturday night and Sunday morning in the hope someone with information might come forward.
He said the 24-year-old had been socialising at the Queensland Hotel from about 9pm Saturday until 1.55am Sunday.
She was seen in the vicinity of the Royal Hotel about 2.15am before last being seen walking alone in a park near the town's swimming pool on Marshall St about 3.30am.
Det. Isherwood said Ms Jeffery was walking towards the pathway that leads to the Goondiwindi Waggamba Community Cultural Centre.
Her body was found in the river behind the cultural centre about 10.50am.
"We've assumed that when she was seen by herself she continued to walk by herself until she reached that point where we believe she was attacked.
He said it was about 20 metres from the top of the levee bank to where she was found.
"She was right on the edge of the water," Det. Supt. Isherwood said.
"She was partially clad at the time so it reasonable to assume that the actual death is suspicious."
A post-mortem examination is being conducted to determine Ms Jeffery's cause of death.
He asked anyone who saw Ms Jeffery on the night, whether it was while she was inside the Queensland Hotel or after she left, to contact police.
