The material evidence which needs chemical examination should be sent immediately to the Forensic Science Laboratory without delay. Special care is to be taken in cases where viscera is preserved by the doctor for final opinion on the point of cause of death. The viscera loses its characteristics within six month so it is to be ensured that it reaches FSL within one month of its being collected. If it is not observed by the IO then prima facie it would be understood that the evidence is destroyed by the IO and he would be dealt with severly.
