Later that night his car, a silver Peugeot 306, was found on the A467 between Risca and Crosskeys. Police said it was believed to have been in a collision.
Despite a nationwide appeal, a growing campaign online for information by Mr Vaughan and intense searches by police and family and friends there have been no sightings of the Unilever worker and former Cwmcarn High School pupil.
On Saturday officers visited his family and told them that they now feared that he had died.
Mr Vaughan is 5ft 8in (1.72m), with a slim build, and short dark hair and brown eyes.
He was known to wear a gold neck chain with a cross and has a distinctive tattoo of a pair of flaming dice on his inner left forearm as well as tattoos on his right leg.
