THE mother of a Newport man whose death sparked a murder investigation has said she will never come to terms with her son's demise.

Gwent Police launched a murder probe after homeless man Jeremy Vaughan, 42, was found dead with facial injuries in a tent on Maendy Way, Cwmbran, on September 28, 2012.

An inquest heard on Tuesday that Jason Blight, initially held on suspicion of Mr Vaughan's murder, was a friend who had allowed him to stay in his back garden for a few nights.

A neighbour said they heard someone in the garden "in pain" and "crying" two days before Mr Vaughan's body was discovered.

Detectives arrested Mr Blight but he denied any involvement with the death and was later released without charge, Gwent Coroners' Court heard.

A post-mortem showed Mr Vaughan had died of blood acidity, caused by alcohol misuse and type 1 diabetes.

Now his mother Marion Shaw, from Newport, who attended the inquest, has said she will never find closure despite having a verdict.

"I am not satisfied with the verdict, I'll never be satisfied," said Mrs Shaw, who made a plea for information relating to her son's death last November. No one came forward.

"I would have liked a little bit more (information) for my son's sake. Why was he in the tent? I don't think my husband will ever come to terms with (the death)."

Mrs Shaw, formerly of Hendre Farm Drive in Newport, moved house after the death of her son, who she called Jerry, as she kept seeing his face in the house.

"To sit through the inquest was very disturbing for me, it was awful," she said. "What they said about my son really hurt me, he was crying out for somebody to help him and no one came. I never knew any of that."

Mr Vaughan is buried at St Mary's Church on Malpas Road and Mrs Shaw goes most days to see the grave.

"I am never going to get closure, I'm never going to find out what happened and perhaps it's best I never do," she said. "I'll just have to come to terms with it.

"The coroner was lovely when I collected Jerry's death certificate but I got no comfort from the inquest, what mother would," she said.
