SOON after Carly was born, doctors discovered that she had total allergy -- was allergic to everything.

The only thing she could consume was breast milk, and an appeal was made which resulted in women from across the North-west donating milk for Carly. Eventually she was able to return to a normal diet.

However, aged four she contracted salmonella, and it was shortly after recovering from this that Carly was diagnosed as an insulin dependent diabetic who required a highly specialised diet and regular doses of insulin.

Before her parents' divorce Carly and her family lived in Cope BanK, Smithills and she attended Church Road County Primary School.

She went on to Smithills High School and halfway through moved to Hayward Secondary School in Great Lever.

Her mother remarried and moved to South Yorkshire, taking Carly with her but the teenager kept running away.

She was reported missing several times from Doncaster and was believed to have come back to the Bolton area.

During the last couple of years of her life, Carly was under the care of Bolton social services and had lived in various children's homes and local authority accommodation.

Until about five months ago, she was a regular visitor at the Westhoughton Youth Drop-in Centre in Bolton Road.

For nine months, the teenager took part in its drugs and alcohol dependency programme called Wasted.

Then she was referred to the Bolton Council-run Project 360 which is a a more intense substance misuse scheme for under 18s.

No one knows why she stopped going to the drop-in centre and staff are shattered by what has happened.

A spokeswoman said: "We are devastated by what has happened.

"I am in shock and it such a shame for a young girl.

"We haven't seen her for the last four or five months. It was up to her if she wanted to ask for our help. We went around to her home several times so she knew we were here if she needed us.

"Carly was a nice girl. She felt the system had let her down. She wanted to come off the drugs but she wanted more help."

During the summer, senior police chiefs and social services bosses held a series of emergency meetings to discuss a number of young prostitutes who were thought to be at serious risk.

It is understood that on one occasion Carly had been bundled into the back of a car in Shiffnall Street and was missing for several days.

On her return, the teenager refused to tell anyone what had happened to her.

A source told the BEN: "The police and social services were very concerned about her welfare.

"It was even said that she was going to end up being killed.

"Carly would not say where she had been taken.

"There were about half a dozen girls who were in care and were working as prostitutes."
