Walt's Movers: Discreet Document Removal and Destruction Service for Elite Clients. (A subsidiary of the Trump International Crime Family of Properties))

Wally has identified the mover of interest. It is not Cristine Bobo but rather "Walt Nauta". Walt is described by Wally as "a former military valet who went to work at Mar-a-Lago after Mr. Trump left the White House." Thus his career alternatives. Walt was the schlump who was seen on surveillance tape moving boxes from "the storage room" both before and after the Justice Department issued a whatcha call subpeeny for documents purloined by the Don after he fled the White House. Walt is the same individual, now named, referred to by Chief Wahoo as initially lying to federal gumshoes that he moved any boxes then when apprised of the video admitted moving the top secrets on the orders of the Don.

Wally has identified another active and intelligent swan who DOJ has seen swimming in the MAL sewer, "Will Russell."  Will's resume includes "serving" inside the White House with a brief covering covering "coordination of presidential travel". Here's Will coordinating the travel of presidential records at an unidentified time:

I am surprised to see Will overflowing a bit for a person of his age and the obviously physically strenuous nature of his travel coordination duties and would respectfully suggest to Will for its health benefits maybe running with those boxes to increase caloric burn. No doubt he has given thought to running.
 

Will transitioned from the White House to the MAL Lagoon after 45th vamoosed. The Federals talked to Walt and Will, "months before" is as precise as Wally can be, the search warrant in Aug. Walt's uneven performance in his two interviews is now a matter of record. 

In Wally's wording these two talented mammals, "aren’t formally cooperating with the probe..." However there is a bit of confusion in Wally's report, viz: In the first paragraph of the article, Wally's pencils write,

Federal investigators contacted at least two aides to former President Donald Trump months before the FBI searched his Mar-a-Lago resort and have sought to talk to them again in recent weeks...

We are clearly to understand that both Walt and Will spoke to DOJ once, since DOJ wants "to talk to them again." Yet in the next paragraph (two of only two) Wally writes,

Mr. Russell hasn’t personally spoken to investigators, who are communicating directly with his counsel.

Perhaps he has retained the services of Christine Bobo, Esq.?

And Wally points to another two rat holes Trump may have the purloined papers secreted in:

Federal officials also have expressed concern about whether Mr. Trump took documents on flights as he traveled from Mar-a-Lago to his other properties in New York and New Jersey, according to a person familiar with the matter. 

The undersigned in modesty and sincerity suggests to his betters in the Department of Justice that they not neglect the sewer systems in New York City and Bedminster in their searches as one never knows what swans may be found swimming among flushed paper, toilet and top secret, at Trump International Properties.
