A few friends meet at a guesthouse. In the wake of the night, Aleph is killed by someone among them. Before Aleph breathes for the last time, he cleverly writes and mark something on his pocket calendar, careful not to write the name of the killer because he knows the killer is smart enough to get rid of any evidence.

The police arrive at the crime scene and searches for the evidences; not able to find any. Then they find a pocket calendar inside the inner pocket of the vic jacket.

Attached is the image of the pocket calendar. Can you guess the name of the killer even though you dont know the name of the friends?

A.
The numbers 12, 4, 8 and 3 are written by Aleph. A few numbers are also circled.

Its fair to assume that the circled numbers refer to the letter present on that position of the month name and the written numbers define the sequence of the letters.

12 = December
5th letter of December = M

4 = April
4th letter of April = I

8 = August
6th letter of August = T

3 = March
4th and 5th letter of March = CH

Therefore, the name of the killer is MITCH.
