far as the second period is concerned, while roll number 24 is shown absent and written in sequence, roll number 40 does not immediately follow roll number 24. What follows roll number 24 is 41. Below all these numbers, roll numbers 40 and 24 are again written and encircled. As submitted by the learned counsel for the accused, this is indeed a strange practice. When all those roll numbers which have remained absent were already noted down together, why only two of the numbers should again be written and circled is not known. At the same time, why roll number 24 was repeated and circled whereas 40 is not at all shown in the first list of absentees is not explained. In other words, it is not clear whether Rohit was in fact absent. The evidence of PW-1 in this regard is unhelpful. There had to be some independent evidence to show that both Rohit and the deceased were together absent from the second period onwards. The evidence placed on record does not convincingly prove this. Even the time of the occurrence, i.e., 10 am does not quite tally with this piece of evidence. The prosecution did not bother to prove the actual hours during which the classes took place, i.e., whether the first period began at 9 am or earlier.
