These changes may include minute details like turning off lights or opening of doors or windows etc. The investigator must start examining the body and should be careful to avoid damaging any evidence present at the crime scene. Carefully observation of the ground around the body is necessary. The investigator has to search for items of evidence or those which have some evidential value like some stains, marks, etc. The investigator should remember that every crime scene has three dimensions and for that reason a thorough search is necessary. The investigator can use another technique of locating the evidence – by throwing a flashlight on the ground at a slanting angle, which is very crucial also during the daytime. Through observation and documentation of the items are also important especially in the order in which the items were placed. Close attention should be given to each and every minute detail as one approaches the body or the exact place of the crime incident. It is also advisable not to dismiss any such material until its evidentiary value can fully be determined. Details in the form of footprints or drag marks or in some cases the marks on the ground or sign of minor destruction are most valuable for further investigation. These are the regular investigation or the routine pattern which are being discussed. But the analysis of the collected evidence is an area of study. With the help of modern science and technological advancements, there are plenty of cutting edge investigation methods used to detect the actual criminal.With the forensic scientists looking for more sophisticated techniques to form the latent fingerprints, cyanoacrylate (CA) fuming has gained much popularity. (Bessman, Nelson, Lipert, Coldiron, Herrman). CA fuming is one of the many improved ways used to develop the latent prints and also has been in use for many years now.
