Parents' appeal over missing man
The devastated parents of a man whose disappearance is being treated as murder have launched a heartfelt plea for information.
Kyle Vaughan, 24, known to pals as "Jabbers", was last seen on December 30 2012.
Police later found his damaged silver Peugeot 306 abandoned in the South Wales valleys on the A467 between Risca and Crosskeys later the same night.
Detectives say that while it is unknown whether he had been driving the vehicle, they believe it had been in a crash and that Mr Vaughan had walked away from the car.
His parents Alan and Mary Vaughan say not knowing what has happened to their son is killing them.
Mr Vaughan said: "Our family is totally devastated. We just don't understand why Kyle was murdered.
"The people who have hurt our son, or know what happened to our son, have not just killed him but they're killing me and Mary."
His father said the process of accepting their son's death in the absence of a body had been a long and difficult one, and all that they now had left was hope they could at least give him a funeral.
"We just need a bit of help from the public to help our son," he added.
"The day we finally get to bury Kyle is going to be a very sad one. But it will also be a happy one in one respect because we can finally say goodbye to him and put him to rest."
Gwent Police insist they remain fully committed to finding the truth about what happened to Kyle Vaughan, of Newbridge, Caerphilly county.
Detective chief superintendent Peter Jones, who is heading the investigation, said it had been one of the most extensive cases he has ever worked on.
"This is very much still a live investigation and we remain fully committed to establishing exactly what happened to Kyle a year ago today," he said.
"Someone out there will know what happened that night and I would urge them to come forward with any information they may have."
Detectives upgraded their inquiry to a murder investigation within a week of Mr Vaughan going missing and a dedicated team of officers remains on the case.
Specialist officers also remain in close contact with his family to support them and keep them up to date on progress.
In the last year police have analysed more than 1,800 pieces of property including more than 180 mobile phone sim cards.
Around 4,800 mobile phone contacts have been investigated and more than 10,000 lines of telecoms data, such as text messages, have been analysed.
Officers have visited more than 130 CCTV sites and analysed more than 200 hours of footage and have collected more than 390 individual statements.
A £5,000 reward for information about Mr Vaughan's disappearance has also been made.
During the investigation eight people have been arrested, including two men from the Blackwood area, aged 25 and 27, on suspicion of murder.
All have since been released but the two men, and one other person, remain on police bail.
Anyone able to help police should ring Gwent Police on 101 or Crimestoppers on 0800 555111.
