THE heartbroken mother of Emma Caldwell, who was murdered 12 years ago, has made a fresh appeal through BBC Crimewatch for help to find her killer.

Emma Caldwell, 27, was found dead in Roberton Woods near Biggar, South Lanarkshire, in May 2005, one month after she was last seen alive.

Her mother Margaret urged anyone with information to come forward. She said: “You’re out there – you know this man is a danger to other women.”

She described how Emma was missed by her family “every day” and added: “Please help us as a family, please come forward, that’s all we need.”

The Crown Office asked police to reinvestigate the case in 2015.

BBC’s Crimewatch Roadshow showed CCTV footage taken on April 4, 2005, which showed Emma walking along Inglefield Street shortly before 11pm – the last time she was seen alive.

She had been working as a sex worker in Glasgow at the time of her death and her body was found about 70 miles away from the city centre.

Police Scotland Detective Superintendent David McLaren said that he would like to hear from other sex workers who were working in the city in 2005.

He said: “We know from our investigation it was unusual for women involved in prostitution to go so far from the city.

“I’m certain there are women out there who have been taken to that location or taken excessive miles outside Glasgow, while they have been involved in prostitution, either back in 2005 or maybe still today. You can see the impact Emma’s death has had on her family.”
