The report states that the death of the victim was caused by manual strangulation associated with smothering, reported The Indian Express.

Several media reports said the autopsy concluded that there was evidence of "forceful penetration/insertion in her genitalia", which indicates sexual assault.

The report states there were 16 external injuries on the victim's body, including abrasions on the cheeks, lips, nose, neck, arms and knees.

Nine internal injuries were also found.

There were injuries to her private parts as well, reported the newspaper. All injuries were inflicted before death.

The report said "white thick viscid fluid" was found inside her private parts, reported India Today. However, it didn't mention the nature of the substance.

The victim's father has alleged that more than one person were involved in the grisly murder.

The CBI, meanwhile, has been grilling Sandip Ghosh, the ex-principal of the medical college and hospital. They have asked him why he made the parents of the victims wait for three hours before letting them see the body of their daughter.
