Time to be detective

Is this a muder or sucide case? Tell us your logic.






Here's what I think:

Few things that hint that this is a murder and not suicide.

1. The gun is in the right hand and the blood has splattered on the wall on the right side.
2. The victim was clearly sitting and writing at the desk and also smoking at the time he was shot. If it would have been a suicide he would finish the cigarette and then shoot himself.
