"We are conducting house to house inquiries in and around Mr Griffiths' home and forensic examinations are also ongoing."
The victim had a wife and two grown-up sons. Other people were in the house at the time of the murder, but none were injured. Police think Griffiths may have disturbed an intruder.

"He took great pride in his business and it gave him immense satisfaction that three generations of the Griffiths family were employed there.
"Joe's sudden and tragic demise has shocked and saddened all who knew and loved him, and has left a great void in all our lives. We will miss his forthright views and wicked sense of fun.
"Joe leaves behind a wife, two sons and seven grandchildren, who all completely adore and miss him.
"The support from our friends, our customers, old and new has been overwhelming, we greatly appreciate it."
