Colin Campbell

Pretty as a picture in a bright yellow dress, 16-year-old Jacqueline Johns grinned cheekily and waved to the bride as she rushed from the reception to get her last train home. The shy insurance clerk had thanked Susan Baynes for the 'lovely time' she had at the wedding on the Essex Riviera and happily bustled from the door tottering on her platform shoes. Jacqueline's destination was home in Thornton Heath, South London , but she never made it and hours after she said a cheery farewell to the bride, her life was cruelly snuffed out. The teenager's body had been stripped of clothing and dumped in a railway siding in the shadow of Battersea Power Station, across the Thames from where she was last seen at Victoria Station. The date of that horrifying discovery was October 1, 1973 - and almost 51 years on her murder has never been solved and no suspect found. The family of the tragic teenager told MailOnline today that Jacqueline may have been a victim of notorious serial killer Robert Black - but her siblings have not had any contact with the police since a detective suggested him as a suspect more than 30 years ago. Jacqueline's sister Susan said today: 'It is almost as if her case has been wiped from the face of the earth'.

She has battled through pain to model for some of the world's biggest fashion brands. Now Scot Lady Jean Campbell has revealed she turned down surgery that would leave her pain-free because it would have taken her six years to recover. At 15, Lady Jean was diagnosed with hip dysplasia - an abnormality of the joint where the socket does not fully cover the ball ­portion, increasing the risk of dislocation. She has undergone operations and had to use crutches or a wheelchair. The 27-year-old has admitted her condition has 'cast a dark cloud over my whole existence'.

She is the glamorous international model daughter of two Scottish aristocrats. However, a ski-ing accident when she was 12 has left Jean Campbell in constant pain for the past 15 years. Now in a podcast called I'm Fine she has talked for the first time about living with the condition and how meditation and gentle exercise has helped her cope.
