This was no road rage, it was murder pure and simple. The scumbag had a knife on him. WHY??? He was out looking for trouble by the sounds of it and that poor man fell victim to a despicable act of violence.
Absolutely horrific. His poor family. Already having gone through the trauma of cancer and all that brings with it, only to die at the hands of a murderer over something as small as a bump to the car. Makes no sense whatsoever.
R.I.P Mr Lock.
