Mr Thomas was found dead at his home in Ely Road, Chittering, on the 18th December. It is believed he was killed between 9.30pm and 10.30pm the previous night during a botched burglary.
His Rover 75 estate, registration BJ51 CJV was stolen and three distinctive watches were found to be missing from his home along with a leather horseshoe wallet. The car was only capable of slow speeds and was later abandoned in Church Lane in Milton.
A 22-year-old man and a 21-year-old woman remain on bail in connection with the investigation.
Detective Chief Inspector George Barr is appealing for fresh information, three months on from the murder of Mr Thomas.
