**RÄ°ddle**: It was the first day of the college when a young girl was found dead on the college premises. The police narrowed down four suspects.

1. The Dean: He claims he was in his office whole day.

2. Maths Teacher: She claims that she was giving her students grades.

3. Peon: He claims that he was bringing the mails.

4. Mathew: He claims he was cleaning the roof of the college.

Who was the murderer?
