In China, a young man was filmed taking a leap from an overpass. The video contains two different angles of his jump – one from the overpass, and one from the ground level under it.
While I didn’t get any background info, the ground level footage shows him landing on his back. That type of landing would likely result with the back of his head slamming hard onto the pavement, making the jump fatal, and thus, suicide successful.
Props to Best Gore member @BoscoTkc for the video:
