Police investigating the disappearance of Madeleine McCann, the then-3-year-old U.K. girl who went missing in 2007 in Portugal, are looking into a theory that she left her parents’ vacation apartment to find them.
The theory revolves around the girl waking up and wandering out of the vacation home in Praia da Luz, Portugal, according to The Sun. Detectives working with the Metropolitan Police discussed the matter with Portuguese police, the report said.
