An Invercargill resident asked police a few weeks ago to check CCTV footage in the business area close to where the body of Raymond Horn was found to establish whether he had been there.
Police confirmed they had searched the general area where Mr Horn was eventually located, but that search had not included the specific location where he was found.
The body of the 68-year-old Invercargill man was found last Friday among trees and bushes, close to a popular walkway near Bill Richardson Dr in Invercargill.
Invercargill resident Mikayla Scobie lives near Queens Park.
As her property was an area of interest, Land Search and Rescue volunteers searched her Windsor garden about two weeks after Mr Horn went missing.
Ms Scobie’s partner had told police to check Bond St down to Bill Richardson Dr for security cameras, she said.
"He [her partner] was in the process of installing three security cameras at businesses along there."
He also said to check the "whole" of the Waihopai Walkway.
A police spokesman said hundreds of man hours were put into the search for Mr Horn.
"Search areas were determined based on information police received about Raymond’s life and routines, [possible] sightings of him after he went missing, and statistical ‘lost person’ behaviour profiles for people with his conditions."
Police previously said the Waihopai River, parallel to the walkway, had been searched.
However, in the first week of Mr Horn going missing, Sergeant Ian Martin, of Invercargill, acknowledged that the search area should have been widened earlier in the process.
Police did not answer questions on whether camera footage had been requested from businesses along Bill Richardson Dr, or whether anyone had told them to look in the area where Mr Horn was found.
As with all Search and Rescue operations, a debriefing would be undertaken to understand if there was anything that could be applied to future similar operations, the police spokesman said.
Mr Horn’s brother, Wayne, said he could not fault either the search or those involved.
His death was not being treated as suspicious and would be referred to the coroner.
"Cause of death is not for police to comment on."
