While conducting post-mortems, doctors generally examine three main body cavities – skull, chest and abdominal part – apart from the injury-specific areas. “The vital parts are examined as any serious injury to them would cause certain death,” says a forensics doctor. During the procedure, the doctors are assisted by two categories of workers.

Mortuary attendants receive, preserve and hand over bodies, ensure documentation and also collect, preserve and seal the samples for further examination in laboratories and prepare documents in this regard.

Sanitary assistants help doctors handle the body and assist them in dissection. “Every procedure has to be carried out in the doctor’s presence,” said the doctor.

“The samples could be semen in rape cases, bloodstains, clothing, liver, spleen, half portion of both the kidneys, a part of the intestine besides tissues for microscopic examination to study manifestations of any disease (histopathology) and DNA analysis,” says the doctor, adding that their careful handling also requires a stress-free work environment and requisite expertise, in the absence of which crucial evidence may get lost.
