A dog who is trained to find human remains has been brought in from the United Kingdom to help in the search for Theresa Parker, the Walker County 911 operator who has been missing for almost six months.
FBI Regional Director John Parrish said Martin Grimes and his English springer spaniel Eddie are some of the best in the world at finding bodies.
Walker County Sheriff Steve Wilson introduced Mr. Grimes and Eddie at a press conference in LaFayette on Thursday afternoon.
They are furious at the manner of the questioning and may decide to stay in Portugal to clear their names and revive the search for their girl, who vanished four months ago while her parents were at a nearby tapas bar in the resort of Praia da Luz.
Portuguese sources said police were using a “war of nerves” in an effort to make Mrs McCann “crack” and confess to killing her daughter.
Her two interrogations last week – the second lasting 11 hours – were described as “aggressive”, with officers said to be “exploring her weaknesses”.
Media reports said the couple used their right to remain silent and refused to answer “more than 40 questions”. Friends insisted they answered all questions put to them.
