Preliminary examination revealed that one skull belonged to a 40 to 45-year-old woman while the other belonged to a 60-year-old man, police said. They were not decomposed and had hair, they added.
The police questioned the driver who had dumped garbage at the spot a few hours before the heads were discovered.
The driver told the police that he had picked up the garbage from Nanavati Hospital, Vile Parle, and that the skulls could be a part of the waste collected from the hospital.
“Prima facie, it does not appear to be a case of murder as the heads appear preserved. They will be sent for post mortem. We have not registered any case as of now,” said an official from the Oshiwara police.
Dr Ashok Hatolkar from Nanavati hospital admitted to a lapse on the part of the hospital. “ We have a temporal bone lab where surgeons learn disection of the temporal bone in skull. The bones were given to us by JJ Hospital for teaching purpose. Some lower-level person has mistakenly disposed of the bones in garbage and it’s human error.” The hospital has been running the course for the past 20 years.
If it is ascertained the heads came from a hospital, an inquiry would be conducted as human body parts are not supposed to be dumped in garbage, the police said.
