NICOSIA, Cyprus (AP) — Police in Cyprus are searching a man-made lake for suitcases in which an army officer, who confessed to killing seven foreign women and girls, said he stuffed the bodies of some of his victims.

A police official told the Associated Press Saturday that remote-control cameras have located a suitcase in the lake, part of a now-abandoned copper mine.

The official was speaking on condition of anonymity because he's not authorized to disclose details of an ongoing investigation.

A court on Saturday extended the detention of the 35-year-old Cypriot National Guard captain for another eight days.

The suspect, who has not been named, was arrested last week after the discovery of a Filipino woman's body in an abandoned mineshaft triggered a wider investigation.
