Reconstruction Of The Disappearance Of Alice Gross

LONDON, ENGLAND - SEPTEMBER 25: Jose Gross and Rosalind Hodgkiss, the parents of missing teenager Alice Gross stand next to a poster appealing for information near their home in Hanwell on September 25, 2014 in London, England. The hunt for Alice Gross from Hanwell, who went missing on August 28, is now being described as the largest police search operation since the 7/7 bombings of 2005. The police inquiry is now focused on a key suspect, Arnis Zalkalns, a Latvian builder, who was seen in the vicinity of Alice's last sighting. (Photo by Dominic Lipinski - WPA Pool/Getty Images)
