THE family of missing Newbridge man Kyle Vaughan, who disappeared on December 30, have said they are in ‘limbo’.
Since his disappearance eight people have been arrested in connection with the murder investigation.
Police are still questioning two people arrested on suspicion of the murder of Mr Vaughan, who has been missing for more than three weeks.
His silver Peugeot 306 was found on the A467 between Risca and Crosskeys.
A 27-year-old woman and a man aged 28, both from the Cwmfelinfach area, were arrested on Tuesday. Gwent Police have been granted an extention until Thursday evening to question the pair.
Mr Vaughan’s cousin Becky Imm said: "We just want anyone who has seen him or heard from him to tell us – it’s all relevant and it all helps us to build up the bigger picture of what happened to him.
"The family is going through a range of emotions. We’re confused because we just don’t know what has happened to him, especially with all the different arrests. We are trying to make sense of it all and nothing is making sense. We feel like we are in limbo.
"I think people know things they think aren’t relevant, like who he was with and what kind of mood he was in, but this sort of information could be very important.
"We’re urging people to come forward if they saw him before and especially since his disappearance.
"We just want to know he’s safe, alive and well."
Det Supt Peter Jones, who is leading he investigation, said: "Because of the information our officers have obtained over the past three weeks, we decided this is now a murder investigation.
"Obviously we hope Kyle walks trough the door of a police station in the next 24 hours, but because it is so out of character and because of the information we have obtained, we are treating it as a murder investigation.
"We are as sure as we can be the Kyle was driver of his car, but we have no sightings of him after that. We are urging people to come forward if they saw Kyle either in the lead up to his disappearance or after."
The family have also set up a Facebook page, Help us with information: MISSING – Kyle Vaughan, which already has more than 12,000 members.
