Remember four-year-old Madeleine McCann? Went missing four years ago while she was on holiday with her parents. The parents left her and her two younger siblings alone in the apartment while they went out to dinner.
Apparently a British woman thought she saw her in India. Her American companion tried to detain the little girl. All because they felt sure it was a girl they had never met who disappeared four years ago. Yeah.
