Kettering haulage firm Knights of Old have paid tribute to their former chairman, Donald Knight, who was found dead along with his wife at their home near Loddington earlier this week.
Mr Knight,78, was descended from the founder of the company, which was created in 1865.
The bodies of he and his wife Margaret, 77, were found on Wednesday afternoon (May 1).
A spokesman for Knights of Old said: “In relation to the sudden and tragic deaths of Donald and Margaret Knight, we would like to pay tribute to the family name to which we continue to trade under today.
“Mr Knight was the third-generation of his family to head Knights of Old and held the position of chairman up until a management buyout when he retired 15 years ago.
“A few of us had the privilege of knowing and working with Donald and Margaret and they will be sadly missed in the community.
“Our sincere thoughts and condolences are with the family at this very sad time.”
Earlier today, Northamptonshire Police revealed the results of Mr and Mrs Knight’s post mortem.
They said the couple had both died as the result of gunshot wounds to the head.
The police have said they are not seeking anyone in connection with the deaths.
