Llywelyn Thomas was found dead at his home in Ely Road in Chittering on Sunday, December 18. Police believe he was killed during a botched burglary.
The 76-year-old retired farmer had moved to the town with his late wife so that they could be closer to their son, Richard.
50-year-old Richard paid tribute to his father and appealed for people to come forward with information about his killing.
Police continue to appeal for information about the murder, and in particular three distinctive watches which were taken from his home along with a wallet.
Detectives also want to speak to anyone who saw Mr Thomas' silver Rover 75 estate, registration BJ51 CJV, which was also stolen during the burglary between 9.30pm and 10.30pm on the night he was killed. The car was later found dumped in Church Lane in Milton.
