THE family of a 35-year-old mother of two who was battered-to-death in her home are worried it is becoming Huddersfield's forgotten murder.
But Huddersfield police commander Chief Supt John Holt - who worked on the original inquiry - believes the killer will eventually be caught.
Sarah Lewin, 35, was brutally killed at her home at Bradley Boulevard, Sheepridge, 10 years ago in the early hours of January 14, 1994.
Sarah was known to be scared in the weeks before her death and her family are still anxious to discover why she was so fearful.
She was so worried she had even put her children into foster care so they were safe from harm.
Sarah's mother, 61-year-old Pauline Bennett said: "Sarah had moved to Sheepridge from Bradley about six months before her death so we did not see her as much as we had done before.
"But we do know she was very agitated and need to know what it was all about."
Pauline said the passing years had not made the burden of grief any easier.
"It keeps eating away at me inside," she said. "I keep thinking that as the years go by I will not be as upset, but I still am.
"Sarah's death is always on my mind. There is so much hurt. I thought things might improve, but they never do."
Pauline is totally convinced - along with the rest of Sarah's family - that Sarah knew her killer.
"She was always so security- conscious," said Pauline.
"She always looked through the curtains to see who was at the door before letting them in. Someone knows who was responsible."
Sarah's sister, 42-year-old Lorraine Castle, added: "I even think that some of Sarah's friends may even know who killed her and why, but how anyone who has information about this keeps quiet is beyond me.
"How can the person who did this have lived with their guilty conscience for 10 years?
"Surely they must have let some information slip during that time.
"Why is no-one talking about this any more? It's getting almost as though Sarah never existed, which is an awful feeling."
The file on the case has never been closed and the police have all the original exhibits and evidence collated at the scene.
But they need people to come forward with information that could open new lines of inquiry.
Sarah would have been 45 now and her children, Leanne and Kyle - who were aged nine and four at the time of her death - are now 19 and 14.
Police have always believed that Sarah knew her killer.
There were no signs of a break-in at the house and officers think she must have let the murderer in during the early hours of that fateful morning.
But more than one person could have been involved as Sarah was physically strong and would have fought back.
The murder weapon has never been found, but a heavy, pub-style ashtray was missing from her home and could have caused the 20 wounds that killed her.
A woman in a distinctive pink coat and a man were seen on her doorstep in the early hours of the morning and two men were seen hanging around her home too.
A neighbour later reported hearing a scream at around 3am.
Police say the case has been formally reviewed twice already.
Chief Supt Holt said: "I feel convinced that at some stage Sarah's murder will be solved.
"I am also convinced that the answer to Sarah's death lay locally. People may not have given information at the time because they were fearful or had a misguided sense of loyalty.
"Time has now moved on and it may be the people they were scared of have left the area."
