THIS is the 2.5 kilogram dumbell that the prosecution claim was used by a teenager to murder barmaid Kelly Hyde.

Dyfed Powys police also released a photograph of a dog lead, also soaked in Kelly's blood, said to have been found in the attic of the youth's home.

Also released was a picture of a pair of trainers, again found at his home in Ammanford and again bearing Kelly's blood.

The fourth photograph is of a Lonsdale top, which the youth is accusing of wearing on the day of Kelly's death. Blood stains were a partial match to Kelly's DNA.

The photographs were released after forensic scientist Karen Alexander told a jury at Swansea crown court about the results of tests she carried out on the four items.

Kelly, 24, was murdered on September 27 as she walked her whippet dog Scrappy along a bridal path leading off Mill Terrace, Ammanford. Her body was found face down in a stream. She had died from head injuries.

Karen Alexander said that DNA tests on the trainers and the dog lead were so conclusive that it was a "billion to one" against that the blood had not come from Kelly.

Tests on the barbell, found in undergrowth close to the murder scene, showed the odds against the blood being Kelly's were 290 million to one against.

Patrick Harrington, prosecuting, has told the jury the "twin" of the dumbell had been found at the defendant's home.

The Lonsdale top revealed poor blood samples and the odds of the stains not coming from Kelly's blood were only 700 to one.

Karen Alexander said the trainers appeared to have been wiped clean and the blood stains were found in the lacings and inside the tongue of one of the shoes instead of on the open spaces on the outside.

The youth, who cannot be named because of his age, denies murder and the trial continues.
