Meadow Soprana is working as an analyst for the Food and Drug Administration $($FDA$)$ and has been assigned to a case in which the suspect is believed to be engaged in a rather large drug$-$dealing operation behind the sham business Chubby$-$After Covid. Her first assignment is to perform a net worth method on Walter Wite., the sole proprietor of the unincorporated business.

After Meadow completed her analysis, Walter$$s attorney raised an objection. Meadow asked to meet with Walter again, and at that meeting Walter told her that he believes that the cash on hand amounts that were used in the projection were too low. Although he had provided the amount to her earlier, he now believes that it was much higher than the amounts used and seems to recall that he had about $$200,000$stashed away$$ in case the economy crashed. When Meadow asked him about the source of the $$200,000,$ Walter shrugged and said, $$Part of it was an inheritance from my dear old Aunt Lydia, and the balance was just some money I had saved.$$

How should Meadow respond to this new information $($i$.$e$.,$ would she want additional information from Walter$),$ and what are the sources of evidence that she needs to follow up on his assertion?
