# Who is the killer?

Before dying,the victim managed to pull out the knife from his abdomen,nail it to a calendar,and write 6 , 4, 9, 10, 11 with his blood.

The suspects are Sophie,Jason,Nick,Julie, and Paul.

Who is the killer?

A dying man has no time for encryption. Killer has a 5 letter name. So JULIE or JASON

4 may be 'A', 9 a distorted 'S', and 11 an 'N'.

I opt for JASON.

My feeling was that a dying person anxious to leave a message would be direct and not resort to encryption since he has nothing to lose.

If so, the writing has to be letters and not numbers. Since there were five items the name was probably a five letter one. This narrows it to Julie or Jason.

The data given is not an exact reproduction of the writing in blood. He must have used his finger as a pen. The writing would be distorted.

4 is like capital ‘A’, 9 could well be a distorted ‘S’ if the top curve of the S got smeared or the blood dripped. 11 is actually quite like ‘n’.

10 does include a ‘O’. 6 is a mirror image of ‘J’ with the bottom loop closed.

The probability was for the writing to be ‘JASON’.

Not really a great explanation but seemed to fit the situation better than JULIE.
