The partner of a man killed in an arson attack is piecing her life together with the baby born after his father's death.

Sonia Tomlin gave birth to Jamie three months after the death of 36-year-old James Tomlin in a blaze at their home.

The couple already had two sons, Scott, eight, and Dominic, six, who were rescued from the flames along with their mother.

As Miss Tomlin, 27, copes with her loss, her family believe detectives investigating the murder are awaiting the evidence that will lead to the killers.

Miss Tomlin's mother, Beverley Chadwick, said her daughter is now engaged to "a good man" who has helped her through the tragedy.

It is a year since the blaze tore through the couple's Windhill home, forcing Mr Tomlin to jump from a bedroom window. He died from smoke inhalation after the arson attack on August 15.

Mrs Chadwick said although her daughter, who gave birth to Jamie in November, now had hope for a brighter future, it did not ease the pain of knowing the killers were still at large.

Mrs Chadwick, 49, said the family needed to find the truth behind the attack so they could get on with their lives.

"There is still a missing piece of the jigsaw. We and the police know someone out there must have the last piece we need to convict whoever did this and see justice done," she said. "It doesn't matter how small the piece of information is, it could be the missing bit."

She sobbed as she recalled how Miss Tomlin had described the final moments before firefighters battled their way through the burning house in Prospect Grove to get the couple and their two sons out.

She said: "It could easily have been all four of them who died. Sonia had fallen asleep next to Dominic because she had been up to them in the night when she heard a bang and opened the door to see flames everywhere.

"She screamed for James in the room opposite to wake up. He tried to get to them but couldn't make it. The only way out was the window.

"Sonia managed to call for help on her mobile but she told me she was about to lose consciousness herself and had accepted she was going to die but got both the boys in her arms on the floor and told them she loved them.

"It was only when she felt water on her back she realised they had a chance. She passed the boys into the arms of firefighters before they came back to get her. Dominic was unconscious."

The family have now moved out of the area to a secret address.

Mrs Chadwick praised the support from people, some friends and many strangers from Bradford and further afield, who sent clothes, toys, computers and furniture to help the family.

"It was a hell of a wrench to go through losing someone you love and to have to start your whole life from scratch again, but Sonia is strong and a brilliant mother," she said.

Mrs Chadwick said Sonia, who changed her surname to Tomlin so it would match her son's surname, had now got engaged to a family friend who had been a "tower of strength".

Miss Tomlin's step-father David Chadwick said: "The boys love him to bits. He's a good man. He is giving them the feeling of security they all need and they feel safe with him around."

Investigating officers have made a renewed appeal to the community a year on in the hope of new evidence.

A police spokesman admitted: "It's been a poor response so far. This is a very, very specific appeal for that vital bit of information we need."

Anyone with any information should call Keighley Police on (01535) 617167 or Crimestoppers, anonymously, on 0800 555 111.
