Leaflet drop in Emma murder probe

Emma Caldwell's body was found in a wooded area near Biggar

Police have sent leaflets to about 4,000 homes as they intensify the hunt for Emma Caldwell's killer.

The body of the Glasgow prostitute was discovered in a wooded area near Biggar, South Lanarkshire, in May.

Officers are targeting homes near to where her body was found with A5 leaflets containing her picture.

Detective Superintendent Willie Johnston said someone had vital information about Emma's murder and urged them to come forward.

The 27-year-old had been living at a hostel in the Govanhill area of Glasgow before she disappeared on 4 April.

She had become a heroin addict following the death of her sister some years before and was working as a prostitute on the streets of the city.

Despite a police investigation, which has included a BBC Crimewatch appeal, detectives have been unable to trace Emma's killer.

Mr Johnston, the officer leading the inquiry, said he hoped the leaflet drop would provide fresh information in the case.

He added: "There are still people out there that we need to speak to as part of the investigation.

"It's possible that, due to the remoteness of the spot where Emma's body was found, the person or persons responsible may have had prior knowledge of the location.

"The delivery of the leaflet to all houses, farms or other premises in the local area augments the house-to-house inquiries ongoing there.

"We hope that by targeting homes in the area where Emma's body was found, we might be able to move this investigation even further forward."
