Detectives have widened the timescale of the murder investigation after a postmortem revealed that Sara had suffered extensive injuries, likely to have been caused over an extended period of time.
The initial appeal, which was launched on August 18, has prompted a number of responses and detectives are reviewing them.
They are keen to speak to anyone who knew Sara, or who has any information that could assist the investigation, “no matter how insignificant it might seem”.
Detective Superintendent Mark Chapman, from the Surrey Police and Sussex Police Major Crime Team, said: “It is now two weeks since Sara’s body was found and the impact of her tragic death continues to be felt deeply by the local and wider community, including our officers and staff.
“We would like to thank those people who have already come forward and reported information to us.
“However, we know that there will be lots of people in the Woking community and beyond who will have had contact with Sara who may not already have come forward, and we would encourage them to do so.
“Any information is better than no information – although you might think it’s insignificant, it might be vital to the investigation and in helping us to bring justice for Sara.”
Sara was seen at school with “cuts and bruises” just months before she was found dead, a neighbour identified only as Jessica told the BBC.
“Just before the Easter holidays she was in school and had cuts and bruises on her face and her neck,” she said.
“My daughter had asked what had happened and she said she’d fallen off a bike and then kind of walked away. The next day the teacher announced she had left school and she was being homeschooled.”
