Madeleine pedo clue

A SERIAL child killer dubbed the “masked man” has emerged as a key suspect in the search for Madeleine McCann.

German paedophile Martin Ney, 48, was jailed for life in 2012 for abducting and murdering three children, and sexually abusing dozens more, The Sun reports.

The Portuguese police officer who first led the hunt for Madeleine, Goncalo Amaral, has claimed police are probing a “German paedophile who is in prison”. Ney looks like a photofit of a man seen acting suspiciously before Madeleine vanished 12 years ago.
