The report said "asphyxia as result of compression of her neck and mouth" caused her death. Further tests are being conducted to conclude if the 39-year-old was raped before she was killed.
The Deputy Inspector General of Police in Panjim G Vimal Gupta said they were waiting for the results of "serological examinations of oral, vaginal and inner swabs", adding that he would not like to share any further details of the investigation which could compromise the various theories that the Goa police is pursuing.
Ms Ghurde's domestic help had raised the alarm when she did not open the door on Thursday morning. Using a spare key, her American neighbour opened the door along with the watchman to find her dead.
"We received information about the incident late last night. We found her naked body and the flat had been burgled," said the police officer, Rajesh Kumar.
But police has been unable to ascertain what is missing from the three-bedroom apartment that Ms Ghurde rented, as she lived alone. The police suspect that Monika's killer knew her as there were no signs forced entry into her apartment.
Monika Ghurde, who was from Nagpur in Maharashtra, had moved to Sangolda only in July this year from the neighbouring Provorim village. Sangolda is about 10 km away from Goa capital Panjim.
