From the principle laid down by this Court, the circumstance of last-seen together would normally be taken into consideration for fnding the accused guilty of the ofence charged with when it is established by the prosecution that the time gap between the point of time when the accused and the deceased were found together alive and when the deceased was found dead is so small that possibility of any other person being with the deceased could completely be ruled out. The time gap between the accused persons seen in the company of the deceased and the detection of the crime would be a material consideration for appreciation of the evidence and placing reliance on it as a circumstance against the accused. But, in all cases, it cannot be said that the evidence of last seen together is to be rejected merely because the time gap between the accused persons and the deceased last seen together and the crime coming to light is after a considerable long duration. There can be no fxed or straight jacket formula for the duration of time gap in this regard and it would depend upon the evidence led by the prosecution to remove the possibility of any other person meeting the deceased in the intervening period, that is to say, if the prosecution is able to lead such an evidence that likelihood of any person other than the accused, being the author the crime, becomes impossible, then the evidence of circumstance of last seen together, although there is long duration of time, can be considered as one of the circumstances in the chain of circumstances to prove the guilt against such accused persons. Hence, if the prosecution proves that in the light of the facts and circumstances of the case, there was no possibility of any other person meeting or approaching the deceased at the place of incident or before the commission of the crime, in the intervening period, the proof of last seen together would be relevant
