Police say they are concerned for the safety of a woman from the United States who has been missing since visiting Facebook friends in Wales.
Kathryn Barnes was last seen near Swansea train station on 4 January.
The 32-year-old from Ohio had stayed at various addresses in Swansea, Pontardawe and Milford Haven in recent weeks.
Her mother Lisa Schoonover said her disappearance was “terrifying” and her family was desperate to speak to her.
South Wales Police said numerous lines of inquiry were on-going.
Ms Barnes, known as Kate, arrived in the UK on 8 November.
She is described as 5ft 7ins in height with sandy coloured hair which may currently be dyed black.
She has a British flag tattoo on her wrist and a dragon tattoo on her calf.
She was last seen wearing a black top, blue jeans, a grey jumper and wedged boots.
Mrs Schoonover, who lives in the US, said: “On 8 November our daughter departed for the UK to visit friends she had met on the social network Facebook.
“Our last contact with Kate was on 4 December.
“Since then, all of her contact information from Facebook has been deleted.
“We have no information at all on her whereabouts or condition.
“The friends she went to visit have co-operated with the police but have no information that has been helpful in locating Kate.
“We love Kate and are we very concerned for her safety.
“Not knowing what has become of her is terrifying for all of our family.
“It is not like her not to find a way to communicate with us, even to just say she is safe and well.”
