6. In the instant case, PW-1 has stated that PW-1 to PW-4 and the others came to Kallidaikurichi in a bus and got down from the bus at the bus stop. At that time, they heard the noise from the northern direction. Therefore, they went towards the said direction. When they reached near the Chennai Musicial Shop, they found the accused stabbing the deceased. The occurrence had taken place in a busy locality. There are number of shops situated in the said locality. But, no independent witness has been examined to speak about the occurrence. In our considered view, the presence of these four family members of the deceased, at the crucial point of time, is highly doubtful, as the explanation offered by them is not satisfactory. Had it been true that they came in the bus, either the conductor or the driver of the bus could have been examined. Thus, according to these witnesses, the occurrence was not anywhere near the bus stop, where they got down from the bus. They have stated that they heard some noise from the northern direction. When they were aware of the accused, it is again doubtful as to why they should go in such a long distance to the Chennai Musical Shop, where the occurrence is stated to have been taken place. The distance between the bus stop and the Chennai Musical Shop is not known. It is nowhere in evidence that at the place of occurrence, before stabbing the deceased, there arose quarrel between the deceased and the accused and there was also a commotion. But, there was no commotion and there was no occasion for the accused immediately proceeding with the stabbing incident. If that is so, the story projected by PW-1 to PW-4 that they heard the noise, which prompted them to rush to the place of occurrence is highly doubtful.
