The mother of missing Irish teenager Amy Fitzpatrick will travel "the length of Spain and Gibraltar" in search of her missing 15-year-old daughter, she said today.
Amy has not been seen since January 1st when she left a friend's house to walk to her home in Mijas on the Costa del Sol in the south of Spain.
"We just feel so helpless. It is now 22 days since Amy went missing and there has been nothing at all for the Guardia Civil [Spain's national police] to go on," the girl's mother, Audrey, said in a statement.
"They have done everything - interviewing friends and family, and searching for her - but there has been not a shred of information that is leading to anything positive. Even sightings of her have proved to be wrong.
"We just don't know what to do from here. And we know that the longer it goes on, the less and less people become interested. Especially with the missing little girl Mary Luz in Huelva, which is at the forefront of everyone's mind," Ms Fitzpatrick said.
"She [Amy] is only 15 and she has disappeared without trace. We plan to take our leaflets and posters to as many towns as possible, just in case she has been taken somewhere or has run away and is living somewhere far from here," she added.
Minister for Foreign Affairs Dermot Ahern said today that Irish officials in Spain are continuing to monitor the situation. It is understood that the family has refused formal assistance from the Irish embassy in Madrid.
Police have searched a wide zone around the area where Amy is believed to have gone missing, an isolated lane way which she used as a shortcut to her home from a friend's house.
Officers are searching for a white car belonging to a neighbour of the girl's family, who was interviewed last Wednesday and Thursday.
An Interior ministry spokesman said the man could not account for the missing vehicle and had not reported its absence to the authorities earlier because he did not want to draw attention to himself.
