Divisional Forest Officer M Roy said the postmortem was conducted on the dead elephant after the baby elephant which was guarding it left today.
The carcass of an adult female elephant, guarded by a calf, was found at Banspahari in West Midnapore district yesterday.
A senior forest official said the dead adult elephant could be part of the group of five jumbos roaming the forested belt.
A section of locals, however, claimed a part of the tusk of the jumbo was missing hinting foul play behind the death.
