RIDDLE: How did the police know?

Mustachekitteh
A man was found dead with a cassette recorder in one hand and a gun in the other.

When the police came in, they immediately pressed the play button on the cassette.

He said, "I have nothing else to live for. I can't go on," then the sound of a gunshot.

After listening to the cassette tape, the police knew that it was not a suicide, but a homicide.
