The family of Joanna Yeates have issued a heartfelt appeal for anyone with information to contact detectives and help catch her killer.
In a statement issued by Avon and Somerset Police, they said: "We maintain regular contact with the police, and continue to give them our support and assistance in any way we can.
"We would like to reiterate the request for any information which could relate to Jo's death, however small or insignificant it might appear.
"That single piece could just enable the police to understand what happened, and identify the killer.
"We are optimistic that the increased reward will concentrate people's minds on where they were on that Friday night, and what they saw which might be relevant."
