You Be The Detective
Thanks Annika


A woman was found dead in her den.
She was slumped over on her desk, holding a gun was in her hand.
A cassette tape recorder was on her desk.

When the police entered the room, they pressed the play button on the tape recorder.

This is the message they heard : "I can't go on. I have nothing to live for."

Then the sound of a gun shot was heard.

Question : 
How did the police immediately determine that the woman had been murdered and had not committed suicide?
