Well, considering that, you know...the dead are ****ing walking with no explanation(At least no explanation to the main character), one would be in the right to assume that conventional methods of killing them (I.E. Taking off their heads, Shooting them in the heart, etc, etc.) wouldn't work.
After all, there have been plenty of stories where the dead rise and they don't need a head and can be riddle with bullets and still continue shambling forward and attacking.
