THE green door of Claudia Lawrence’s deserted York home was the backdrop of another desperate appeal by the missing chef’s father for information about his daughter’s disappearance.

Six months to the day after the 35-year-old University of York worker was last seen, Peter Lawrence stood outside Claudia’s terraced house in Heworth Road to make an emotional plea for help.

The 63-year-old solicitor also spoke of his anger at hearing that several men who police knew to have had previous relationships with Claudia were hindering inquiries by denying they knew the missing University of York chef.

Mr Lawrence, who is separated from Claudia’s mother, Joan, said yesterday: “It doesn’t make me frustrated – it makes me angry.

“A great part of all our lives is missing and has been missing for all this time. It feels empty and hollow. But we are convinced that someone out there does know where Claudia is and it is a matter of getting that person to give information.

“If any friend, workmate or neighbour has seen anything at all, even if they don’t think it’s important, please, please tell the police or Crimestoppers and put us out of our misery.”

Claudia’s 37-year-old sister, Ali Sims, who lives in Derbyshire with her husband and two children, Luke, four, and Joshua, one, released a statement describing her torment.

“Six months on and we are no closer to knowing where Claudia is or what happened to her,” Ali wrote.

“As a family, we can’t face another six months of this. We’ve had Dad’s birthday, Mum’s birthday and my youngest son’s first birthday – for us that was the most poignant.

“The two of us, my husband and I, our eldest son, all four grandparents and our neighbours sat in our lounge as he took his first steps – exactly the same group as a year previously when I brought him home from hospital. But one person was missing.

“Our eldest is five in two weeks. He knows Auntie Claudia is missing, but he’ll probably still wonder where his birthday card is.”
