Second thing we find is the time of death. Dead body starts stiffening within few hours of death. This is called rigor mortis. Rate of decomposition of body compared with atmospheric temperature can fairly reveal the time of death. In any murder investigation procedure time of death is important and useful to investigate further.

Third thing is the identity of the victim. From the clothing and other belongings found on the body his identity is confirmed. Identity of the victim is also of great importance to investigate a murder.

This is our initial investigation list. It includes his friends, relatives, co-workers, and many other people. All the names appearing on the list are considered as prime suspects of murder.

Then we look for the motive of murder. From the suspect list we look for people who have enough motives to murder him or who can be benefited somehow by this murder. Benefits may be in the form of wealth, property, conflict, revenge or any other matter.   For the ease of investigation people with no motive found are eliminated from the list. By this procedure we short list the main suspect list.

Now we concentrate on these people. We thoroughly investigate each one of them. We co-relate the evidences collected earlier from the crime scene with these people and make further investigation to find out if we can match some of the facts with any of them.

Finally our murder investigation has come to a place where we are pretty sure about the involvement of the person or persons who could be held responsible for this murder.
