Police given new information yet no action has been taken on it

I met with Assistant Chief Constable of South Wales Police and new information was given to them in relation to potential witnesses who have come forward three months ago this. happen and im being told these witnesses have STILL NOT been contacted by South Wales Police and I'm now starting to question  the so called crime unit at Bridgend who are supposed to be leaving no stone unturned in this investigation.

Talk is cheap and feel the police should have taken statements from these witnesses not happy at all maybe what is needed is a full Judicial inquiry set up by a retired high court judge to investigate the case at least this would be more independent. Im making my position clear I do not trust this unit at Bridgend. 

Thank you to everyone who has signed this petition the fight for justice continues please keep sharing the petition  we need as much support as we can justice must be done for the victims family  kind regards Michael
