Scotland Yard said a body found in Boston Manor Park, west London, on Saturday has been formally identified as that of Arnis Zalkalns - the prime suspect in the Alice Gross murder investigation.
Detectives have outlined what they have described as one of the "most complex search operations" in recent times after Alice Gross was reported missing on August 28.
Police said all lines of possible evidence were pursued until the body of Latvian builder Arnis Zalkalnwas found in a "densely overgrown overgrown" area.
Officers said that recovery of the body required a "substantial removal of forestry" to enable access for forensic teams, before it was removed shortly after 10am on Sunday.
Police previously searched the area where the decomposed body, thought to be that of Alice Gross murder suspect Arnis Zalkalns, was found.
A body thought to be Alice Gross murder suspect Arnis Zalkalns was badly decomposed and could have been in a west London park for a month.
