The discussion surrounding the partial and ambiguous DNA sample, as referenced in Barlow's filings concerning Bryan Kohberger's case, brings to light several critical aspects of forensic science, public opinion, and the legal process. The nuances of DNA evidence, particularly when it comes to distinguishing between single-source and mixed samples, are at the heart of debates both in the courtroom and in the public sphere. Here's a closer look at the implications and challenges of such evidence, and the broader conversation it sparks.

It is of significant importance to acknowledge the concerted efforts made by numerous individuals to scrutinize and challenge Bicca Barlow's characterization of the DNA sample from Kohberger as being "partial and ambiguous.”


Explained: 


In the filing, DNA expert Bicca Barlow meticulously references the Hernandez case, providing a specific citation to underscore its significance in establishing that Investigative Genetic Genealogy (IGG) is considered Brady material, necessitating its disclosure to the defense.


The use of citations serves as a crucial mechanism for both reinforcing arguments and delineating the thematic sections of an argument. Barlow's strategic citation of the Hernandez case exemplifies this practice, effectively utilizing it as a method to conclude the discussion on that particular topic. By incorporating a specific citation related to the Hernandez case, she not only anchors her argument in established legal precedent but also signals the closure of that line of reasoning. This technique is a sophisticated aspect of legal argumentation, allowing the writer to transition smoothly between different facets of their argument.


After citing the Hernandez case as a foundational element for understanding the necessity of disclosing Investigative Genetic Genealogy (IGG) as Brady material, Barlow uses the phrase "in this case" to pivot her focus. This transition is critical; it marks the shift from a general legal principle established by precedent to the application of this principle to the nuanced details of the current case, specifically regarding the “partial and ambiguous” DNA evidence.


In her comprehensive examination, Barlow methodically incorporates the phrase "in this case" ten times, each instance carefully designed to refocus the narrative on the complexities inherent to Kohberger's situation. This intentional use of repetition is much more than a stylistic choice; it functions as a strategic tool to ensure the discourse is consistently centered on the specific details pertinent to Kohberger. By directly linking Kohberger's name with this pivotal phrase, 8 out of the 10 times, the defendant's name plus the phrase clarifies the shift, "in this case."


Discourse deixis is a linguistic term used to describe the way language can point to or reference parts of a conversation or text. This can be particularly relevant in legal writing or any detailed analysis where it's crucial to distinguish between the current topic of discussion ("in this case") and references to external examples or precedents ("in the case of"). In essence, discourse deixis helps to navigate the text, indicating whether we're focusing on the immediate subject or referring to external contexts.
