Emma TV appeal produces new leads

Emma Caldwell's body was found in a wooded area in Lanarkshire

Police investigating the murder of a Glasgow woman have said they are looking at two new leads after the case was featured on national television.

The body of prostitute Emma Caldwell was found in a wooded area in May.

After the BBC Crimewatch feature, detectives said they might be able to identify two people seen talking to Ms Caldwell on the night she disappeared.

Police took 50 calls after the case was highlighted. They believe that someone may be shielding the killer.

On Wednesday night's programme, Ms Caldwell's parents told of their agony as they saw their "lovely, magical" little girl turn to drug addiction before her violent death.

We got a call from a prostitute who gave details of a client who was out in a vehicle on the night Emma went missing Detective Superintendent Willie Johnston

A reconstruction of Ms Caldwell's last known movements in Glasgow was shown in the programme along with appeals for anyone with information to come forward.

Detective Superintendent Willie Johnston of Strathclyde Police said: "I think it probable that the person responsible will have mentioned to somebody or in some way shown adverse reaction to some press coverage of the case."

The body of Ms Caldwell, who disappeared in April, was found in a wooded area near Biggar, Lanarkshire, on Sunday 8 May.

DS Johnston urged prostitutes who may have used a hotel at the Abington service station on the M74 to come forward.

He said: "I would ask that any prostitute who has not yet spoken to us to contact us."

Family video

Within two hours of the show being aired, detectives received more than 35 calls offering information.

DS Johnston said: "We got a call from a prostitute who gave details of a client who was out in a vehicle on the night Emma went missing.

"That vehicle may be out in Glasgow tonight and we have authorised officers to take action on that tonight."

A new picture of the victim was released to coincide with the Crimewatch appeal

The programme showed footage of Emma as a carefree two-year-old at her family home.

Her parents, William and Margaret, gave an emotional account of how Ms Caldwell turned to heroin after the death of her older sister Karen, 31, six years ago.

The dead woman's mother said: "Emma was just a happy, happy child.

"She was full of fun, a magical child who loved horses.

"We had a very happy life."

Mr Caldwell said the family was unaware of how the 27-year-old funded her drug habit.

He told the programme: "If Emma had told us about the major problems she had I would have just brought her home."

The Crimewatch appeal contained CCTV footage

Mrs Caldwell added: "It wouldn't have mattered to us. She was our daughter and we loved her no matter what. No matter what anyone thinks or says about her, she was our child, our beautiful daughter and we loved her.

"To lose one daughter is unthinkable. It's a terrible experience and you think nothing like this could ever happen to me in my life again.

"This is as bad as it is ever going to be, to lose your child. And now Emma."

Viewers were told by Crimewatch presenter Fiona Bruce that the killer could be a drug dealer, a regular client of Ms Caldwell's or possibly a visitor to Glasgow.

DS Johnston added: "People have seen the pain on the faces of Emma's parents. We need the call that will take the pain away from her parents and give justice for Emma."
