Murray River Tragedy: Missing Boy's Body Found At Moama

The five-year-old's body was found on Saturday morning.

Police have located the body of a child following a search of the Murray River.

The tragic discovery comes after the five-year-old boy went missing in the river at Moama, in the NSW Riverina region, on Thursday.

After the boy's disappearance a search was launched and at about 11.35am on Saturday a body, believed to be that of the five-year-old, was located in the water, police said in a statement.

Marine Rescue NSW, Echuca Moama Search and Rescue, Victoria Police and the SES assisted in the search.

The dead boy's mother, who cannot be identified for legal reasons, is facing an attempted murder charge in relation to her other son, who is nine-years-old.

Police told a Deniliquin Local Court hearing that the woman tried to drown the nine-year-old in the Murray River, but he managed to get away, NewsCorp Australia reports.

The mother appeared before the court earlier on Saturday where she was formally refused bail, according to NewsCorp.

She is expected to reappear, via audio-visual link, at Deniliquin Local Court on Monday. Further charges are expected to be laid at that time.

The nine-year-old remains in a stable condition at hospital in Melbourne.
