Property search in missing Susanne Llewellyn-Jones cold case
Police have been searching properties in Cardiff as part of a reinvestigation into the disappearance of a woman more than 30 years ago.
Susanne Llewellyn-Jones, 34, went missing on 14 April 1980 after being taken to Cardiff Central station by her husband. She was heading for London.
South Wales Police said they searched her former home and workplace.
A 68-year-old man from the Vale of Glamorgan has been interviewed after voluntarily attending a police station.
Det Ch Insp Ceri Hughes, of the specialist crime investigations team, said: "Specialist search teams are this week carrying out surveys at Susanne's former place of work and home address.
"These routine inquiries are essential in any long-term missing person case and particularly to our investigation in determining what happened to Susanne."
'Out of character'
Originally from Leicester and known as Sue to friends, Ms Llewellyn-Jones lived in the Llandaff area of Cardiff.
The mother of two said she was planning to visit friends but it is not known if she ever arrived.
She was thought to have had her passport and international driving licence with her.
She was described as being of slim build with blonde shoulder-length hair, brown eyes and a fair complexion.
Ms Llewellyn-Jones's disappearance was said to be completely out of character.
Her maiden name was Grubb and she had been married previously under the name of Stubbs.
South Wales Police said searches at a property in Cardiff Road have now been concluded with no more planned at the moment.
One of the locations searched included Churchills Hotel on Cardiff Road, which was owned by Ms Llewellyn-Jones and her husband.
Former employee Marc Adams-Jones said Ms Llewellyn-Jones was his role model.
"I have been interviewed by the police," he told BBC Radio Wales.
"When she disappeared, at the time, it was felt that it was a family argument and she would be back, but obviously over the years that's not been the case.
"You never expect someone you know to disappear and never be heard from again.
"She was a very driven business woman, the mother of two very nice children, she was a good boss to work for, as was Adrian.
"I don't think anybody can categorically say they know what happened.
"Or if somebody knows what happened it makes you wonder why they didn't come forward 33 years ago."
