I think she was facing the shelf because she has the cigarette in her left hand and the ashtray is on the left side of the shelf. The gun is in her right hand which would suggest it was a murder rather than a suicide because the blood splatter is on the right wall.

What about the paper I can be sucide note ...because of Stress she is smoking cigarette it can also happen

Also, the way that the pen is set down makes it look like she is left-handed... I'm not sure.

The gun spatter, plus, rarely will the gun stay in someones hand if they commit suicide...it's definitely murder.

Murder.. gun in wrong hand for suicide..?

Room is destroyed and there is paper where something is written.so think again..look at the picture in detail ...dont miss anything

This is murder

How look at the picture carefully ,there is sucide note and the room is destroyed it can be sucide also .....Rethink...
