fine, I've got my reasons.
Its true there's a note there, but I think it was planted by the murderer to make it seem like suicide. If she actually shot herself, the gun wouldn't be in her hands and the ciggerrete also. They'd have fallen off the moment the bullet flew from the pistol and hit her hard.
Her slippers is off.
The stool is in a wierd position.
And the blood stain on the wall is a bit far from her corpse if it was suicide.
The gun in her hand, the ciggerrete and the slippers off, shows she was murdered. The killer placed them there after he took her life...
