Vagrant 'watched blaze victims die'.
Vagrant Carl Mills, 28, of no fixed abode, pleaded not guilty to three counts of murder when he appeared at Newport Crown Court yesterday accused of killing his girlfriend, their baby daughter and his girlfriend's mother.
A jury of eight men and four women heard that his victims - grandmother Kim Buckley, 46, daughter Kayleigh, 17, and six-month-old baby Kimberley - screamed in terror as flames ripped through their house.
Kayleigh was seen in the window of a smoke-filled room refusing to leave her child.
Gregory Bull, prosecuting, said Mills watched the flames take hold of the Cwmbran property from an area known as "The Brick".
He said: "He was to sit at that area and simply watch he house catch fire from a distance of 90-odd metres."
The family's shouts for help were heard from the property at 15 Tillsland, Coed Eva, by neighbours desperate to help.
"Kayleigh was seen in the window of a smoke filled room crying for help for herself and her baby," Mr Bull said.
"People urged her to jump but she would not leave the baby. One neighbour heard she had become stuck.
"As far as Kim was concerned neighbours could hear her say that she was on fire."
Dressed in a black jacket and white, tieless shirt, Mills rested his head on his closed right fist as Mr Bull continued.
He told the jury Mills, who had pitched up in a tent in the garden of the home, sent numerous texts to Kayleigh threatening to burn the building in the hours before the inferno.
It was alleged he was jealous of the baby, whose twin Angel was still born, and was convinced his girlfriend was two-timing him. Previously, Mr Bull told the court, Mills had told Kim he was going "burn her out of this earth".
In the home was pure oxygen for baby Kimberley who was deaf, blind and in poor health after being born prematurely. She had only been home from hospital for a matter of hours before her death in the early hours of September 18 last year.
"He knew that oxygen could add to the intensity of a fire once started," Mr Bull said.
The jury heard Mills sent a message to Kayleigh telling her: "Oxygen would blow you up and that is what I want."
