Police are trying to determine the identity of human remains found in a drain at Bamboo Number 1, Valsayn on Tuesday.
The body was so badly decomposed, police were unable to determine whether it was that of a man or a woman.
St Joseph police say they believe it washed down from another area during heavy rains.
However, police say they have not received any reports of missing persons in that district that could help their investigations.
They are asking anyone with information to come forward and assist with the investigation.
