Officials in Portugal are halting their investigation into the case of a 4-year-old British girl who vanished last year.

Madeleine McCann was reported missing during her family's vacation in southern Portugal. A statement from Portuguese officials says detectives have found no evidence of a crime during their 14-month investigation.

The statement says detectives also found no reason to charge any of the three people named as suspects: Madeleine's parents as well as a local resident, Robert Murat.

Portuguese officials say the case will remain on hold unless new evidence comes to light.

The McCanns have waged an international campaign to find their daughter. Lawyers for the family may now ask a judge to grant them access to the police file. Officials have said it runs to 10 volumes.
