Nowadays much progress has been made in the scientific proving process. It is necessary for the persons involved in the judicial process to be knowledgeable, able to understand and aware of the necessity to bring the process into the fearing of fact in murder, a felony which often causes covering up, hiding of evidence, and difficulties in proving the facts to the extent of beyond any doubt. Whereas the proof of fact by eyewitness at the present moment does have limitations on ability to perceive and narration of the matter of each particular person. The distortion of fact can be easily done through the words given by the witness. Whereas, scientific evidence can prove facts related to the elements of offence without said limitation. However, scientific proving is a delicate matter which layman may not be able to understand. It has to rely on expert. There must be a setup of measures and standards in collection, proof and report with correctness to the extent of being transparent and accountable. The acting unit should be independent and uninfluenceable by any mean. Furthermore, these should be two standards for reviewing and hearing of scientific to cut back the discretion of the authority concerned. Hence in this thesis the author proposes the revision of the Criminal Procedure Code in regard of the collection of evidence at the investigation stage to yield clarity and incorruptibleness. Each and every stage must be accountable. These should be one control unit to set standards of proving to reflect international standards and to help the parties equally in proving offence or innocence. This is to ensure that scientific evidence would be valuable in proving the fact to the extent that it entertains no doubt.
