A woman claiming to have special powers found the torso of an adult in bushland in western Sydney while trying to "sense" the whereabouts of missing six-year-old Kiesha Abrahams.

The unusual circumstances led to police officers being called to Nurragingy Reserve at Doonside about 6.30pm (AEST) on Wednesday.

The torso, missing the head, arms and legs, was wrapped in plastic and lying on the bank of a creek could be that of mother Kristi McDougall who went missing two months ago, police said on Thursday.

Police have contacted relatives of Ms McDougall to warn them, although the identity of the torso was still to be confirmed.

Detective Chief Inspector Pamela Young from the State Crime Command Homicide Squad said the woman who found the remains was from the local area and had been trying to locate schoolgirl Kiesha, who vanished from her Mount Druitt home 11 days ago.
