A shadow. He is stuck to the ground, but he is still YOU. Be good to your shadows. :3

I believe this to be a mirror.

If it was a suicidal situation, then the recording would have kept playing, never ending until they turned it off. But since it stopped, it was clearly someone setting him up to say those things so they could murder him without anyone finding out. But, they clearly didn’t think this through very well when they hit the ‘stop recording’ button. It was a murder, not a suicide.
