rope by which the deceased was strangulated. No investigation was made by Investigating Officer as to exactly at which time the accused persons left their house on 06.01.2005. No investigation was done regarding the exact place inside the house where the deceased was actually strangulated by the assailant. He did not investigate whether the assailants, after commission of the murder, sneaked out from kitchen room through tin roof and thereafter by staircase through the roof of the house, because as per A.D. report, ladder was available outside the house to get down from the roof without pointing attention of any outsider. Thus, it appears that the Investigating Officer, while investigating this matter, has taken every possible care to see that accused would get acquittal in the matter. In the circumstances, though strongest suspicion arises against the accused persons, in the eyes of law it cannot be substitute for proof beyond reasonable doubt. Therefore, we have to extend benefit of doubt in favour of the accused persons.
