Against the Head (25/30)

A man is found in the Berlin U-Bahn, having apparently been beaten to death by two youths, who had previously been harassing a disabled man. After being briefly revived, the man dies in hospital. One of the culprits turns himself in, but the inspectors are still groping in the dark as they try to uncover what really happened. Then the victim's smartphone is found - with a recording of the fatal attack.
