The FSL experts had studied the CD of the post - mortem report and found that eight injuries on Sachan's body were large/ deep and not self-inflicted. They also felt the ninth injury on the neck was a post-mortem ligature mark which cannot be self-inflicted.
On their part, the panel of five doctors constituted by chief medical officer (CMO) said in their post-morterm report that there were eight ante-mortem incised wounds and one-post mortem ligature mark on the neck. The cause of death was shock and haemorrhage, they opined.
After the CBI came into the picture, it requested Dr TD Dogra, professor and head of the department of forensic medicine and toxicology, AIIMS-New Delhi, to constitute a board of doctors and associate the experts of the central forensic science laboratory (CFSL) on July 18, 2011, to give an opinion on the injuries and cause of Sachan's death.
The AIIMS board of doctors submitted their report on November 16, 2011. The board said Sachan attempted to kill himself by inflicting incised wounds on the known suicidal sites where arteries and veins were situated.
The injury inflicted on the body did not cut any major vein and the bleeding was slow. When Sachan realised that injuries were not killing him fast, he attempted to hang himself with the belt, the board said.
The immediate cause of death was asphyxia as a result of hanging associated with the bleeding from the injuries inflicted on the body, it concluded.
