Community key to Caroline Coyne murder case
Police have said the local community will know the answer to who murdered a mother of two from Nottingham.
Caroline Coyne was found between two houses in Thorneywood Mount, St Ann's, on 23 July.
A post-mortem examination found 28-year-old Ms Coyne, from Top Valley, who was the mother of two young sons, died from head injuries.
More than 200 people have been spoken to by officers and roadchecks carried out near to where her body was found.
A 26-year-old man arrested in connection with her murder has been released on bail pending further inquiries.
Det Ch Insp Tony Heydon said: "The reason why Caroline was in this area and whether she walked the whole journey is still unclear.
"It is likely that other people may have seen her on the night she died, walking between Breckhill Road, Porchester Road or even heading into Thorneywood Mount, or they may have heard shouting in the area around 1.20am.
"We believe Caroline was attempting to flag down a number of passing vehicles, whether to ask for assistance or request a lift.
"Someone out there knows who did this, and I would urge anyone with any information to come forward, no matter how insignificant they may think it is.
"That one piece of information could be vital in completing the picture of what happened to Caroline last Saturday."
Detectives are continuing to check CCTV of the area.
Last Tuesday, police released CCTV footage of her in Porchester Road, Nottingham, captured by a passing bus, at 01:06 BST on Saturday.
Officers also revealed an earlier sighting in Breckhill Road, Mapperley, just after 00:30 on Saturday.
Ms Coyne, who had shoulder-length auburn hair, was wearing blue jeans with a brown belt, a pink T-shirt with FCUK printed in black on the front, and pink and white trainers.
Police are still searching for one of her size three trainers which was missing when her body was discovered.
