"He then filmed as Simmonds struck far more than one blow to the chest and the heart - the pathologist in the case said there was considerable force used to sensitive areas which was likely to end in death," said Wall, according to Daily Mail.

"It resulted in Mr Riches lying on the ground in a pool of blood and being kicked by one of the other of the group whilst all the time it was filmed," he continued.

The other three defendants were found guilty by joint enterprise. 

The group filmed the killing on a cell phone and played the recording at a party later that evening.

Judge Wall said he could only reach the conclusion upon seeing the evidence that they were "glorifying" the killing.

"Later on there was a party which all four attended and footage was played at it, I can only conclude it was to glory in it there is no other reason it was only stopped when it was learned that Mr Riches had died," said Wall.
