Police in Cyprus have discovered the seventh victim of what is believed to be the island’s first serial killer.

The body of six-year-old Sierra Granze was found at the bottom of lake Memi, southwest of the capital Nicosia.

“Human remains have been found and forensic pathologists are on the scene,” a police spokesman said.

An army captain, identified as Nikos Metaxas, was arrested in April on suspicion of the killings.

Metaxas was taken to the lake after he gave more detailed information about how he disposed of the body, the Cyrus newspaper Philenews reported.
