– Detective Sergeant Mike Griffiths, from Force CID
A double murder of this nature is extraordinarily rare. It is even more unusual for such a brutal crime to take place in a packed shopping area with so many witnesses.
Those people were shocked to the core and were literally queuing up to talk to officers, tell us what they saw and generally get our major investigation off to a good start. These people made a commitment to help the investigation which they saw through to the end when they gave evidence in court.
