Referring to the informant in the memorandum using the informant's initials Best practice requires that informants be identified only by symbols (e.g., I-1, I-2), not by initials, to protect their identity. Cash payments are acceptable but must be accompanied by a receipt.

* "Once a denial is uttered, it becomes extremely difficult for the accused to change his response, because doing so would be an admission that he lied. Therefore, the interviewer must prevent an outright denial, thereby making it easier for the subject to confess".
* "One of the most effective techniques to stop or interrupt a denial is through a delaying tactic... the interviewer should attempt to delay the outright denial; he should not argue with the accused".
Thus, Charles should interrupt with a delaying tactic.

Both the Manual and CFE Prep guides emphasize that deleted files are recoverable until overwritten. Once overwritten, the original data cannot be retrieved:
"Deleted files are recoverable until they are overwritten because data is not erased... until overwritten. So, deleted files that have been overwritten generally are not recoverable." Other file types (deleted shortcuts, hidden files, etc.) can often be recovered, but overwritten files are lost permanently.

The2014 International Fraud Examiners Manualstates:
"Asset hiders look for certain characteristics in the financial vehicles they use to conceal assets. Asset hiders want products that are liquid (i.e., items that can be purchased and sold in a short period of time). Moreover, asset hiders want products that are difficult to trace or untraceable. With such instruments, asset hiders can break or muddy links between the initial receipt of the assets and their final disposition. Asset hiders also look for products that are secure and accessible." TheCFE Prep - Investigationsguide confirms:
"Asset hiders want products that are liquid, difficult to trace, secure, and accessible... NOT transparent."
#Interpretation:
* Accessibility= common desirable trait (correct).
* Transparency= opposite of concealment (not desirable).
* Exclusivity= not a standard consideration.
* Traceability= asset hiders want the opposite (difficult to trace).

Textual analytics is used to extract investigative insight from unstructured data-communications and documents that are not stored in standard database fields-such as emails, chats, memos, and other narrative text. CFE investigative guidance explains that textual analysis applies linguistic methods and statistical techniques to identify themes, anomalies, and linkages within large volumes of text. Its purpose is not to determine truthfulness or deception with certainty (Option A), because text analytics cannot reliably "detect lies" in a definitive way. Nor is its primary objective to guarantee discovery of a confession (Option B); admissions can appear, but that is not the defining function of the approach. Option C aligns more with flow- of-funds visualization or link/relationship charting for financial movements rather than analyzing language content. Instead, textual analysis is performed to categorize and structure text so patterns, sentiments, recurring topics, and relationships between people and events become visible-helping examiners prioritize leads, identify risk indicators, and focus investigative testing on communications most indicative of potential fraud.
