Authorities said a search of the Arade Dam reservoir and surrounding areas in southern Portugal “resulted in the collection of some material,” which will be analyzed, the Portuguese police said in a statement, The New York Times reported.

The girl, who was 3 at the time she disappeared, was left sleeping with her siblings in a resort apartment in the Portuguese seaside village of Praia da Luz while her parents ate at an outside restaurant a few hundred yards away.

She was discovered missing when her mother came to check on the children around 10 p.m.

Divers and police officers with sniffer dogs searched the reservoir and surrounding areas, the Times reported. The reservoir is about 31 miles from Praia da Luz.

According to Portuguese authorities, the search was prompted by a request from German authorities who have been investigating the case, according to the Guardian.

The suspect was identified as Christian B., 45, by the German media. He lived in Portugal on and off from 1995 to 2007, has a criminal record including convictions for sexual abuse of children, and is serving a sentence in a German prison for an unrelated sex crime, the Times reported.
