place and when they reached there, the accused Devarajan was lying on the body of her sister and she told these facts to the police. From the evidence of PW2 in cross examination, it can be clearly understood that when her sister, who went for collecting firewoods, failed to return, PW2 went in search of her and she also heard a noise from the shed attached to the house of the accused Devarajan and at that time, her neighbour Manoharan also called her and informed her that the accused is lying on the body of the victim in the nearby shed. It is pertinent to note that PW2 is an illiterate village woman aged about 73 years and the minor variations in the sequence of events that occurred on the date of occurrence are only natural. It is well settled that normal discrepancies in evidence are those which are due to normal errors of observations and normal errors of memory due to lapse of time and such discrepancies and errors will always be there, however honest and truthful a witness may be. It cannot be disputed that material discrepancies are those which are not normal and not expected of a normal person.
