"These blood clots are composed of two types of red blood cells. The clots in the middle are of one type, while those surrounding them are of another. The two types of red blood cells do not originate from the sa person." Wen Ruzheng finally completed examining the slides.
Director Yuan was stunned by his words. The clots are from two people? How is that possible? How could the blood clots extracted from one person’s body contain two people’s red blood cells?
"Have you done identity verification genetic testing on this blood clot?" Yang Ping had no doubts about Wen Ruzheng’s level of expertise; the fact that he could speak with such certainty in this context indicated nearly 100% confidence.
Dr. Yuan shook his head, "No, an identity-confird deceased person usually does not undergo genetic testing targeted at their identity based on the extracted tissues."
"Professor Yang, can you please help take another look? This will ensure greater accuracy." The matter was significant; Wen Ruzheng couldn’t afford mistakes due to overconfidence and asked Yang Ping to help scrutinize it.
Wen Ruzheng made room for him, given the gravity of the situation. Yang Ping decided to assist and examine exactly what was happening. He sat down and carefully looked at the pathological slice of the clot under the microscope, confirming that the clot indeed contained two types of red blood cells, each originating from a different person.
Wen Ruzheng’s expertise was truly remarkable; for typical doctors—and indeed, there are few pathologists worldwide capable of distinguishing the subtle differences between the normal red blood cells of two different adults. Dr. Yuan’s inability to differentiate was entirely understandable.
"Dr. Wen is right; this blood clot contains red blood cells from two people. The central area’s red blood cells co from one person, while those in the surrounding area co from another." Yang Ping confird Wen Ruzheng’s judgnt after examining the slice.
"This kind of situation is incredibly difficult to assess; even highly experienced top-tier pathologists may not be able to identify it." Yang Ping’s words aid to prevent Dr. Yuan from feeling embarrassed, reassuring him that his inability to discern it was normal.
"Given this situation, we should proceed with genetic testing on the clot. This will allow us to ultimately confirm from a genetic standpoint whether it truly originates from two people?" Dr. Yuan imdiately understood his next steps.
However, if this is the case, then things take a dramatic turn. Originally thought to be death caused by illness, now discovering two people’s red blood cells mixed in the clots suggested one possibility: the blood clot was foreign, originating from another person’s blood.
Why would this happen? Could it be that soone injected another’s blood into the deceased’s body, causing the foreign blood to coagulate into clots, leading to pulmonary embolism with these clots at its center, and subsequently triggering the deceased’s own clot formation process?
If this truly is the case, the murderer was truly clever and ticulous; had he not been cautious and consulted widely after noticing anomalies, he might have been deceived.
This really is a high-intelligence murder thod. Given the critical nature of this, Dr. Yuan decided to take the opportunity to clarify so clinical knowledge; future chances for face-to-face discussions with Professor Yang might be rare.
Sanbo Hospital’s level is indeed well-deserved; they can even identify such abnormalities in pathological slices.
"Professor Yang, since the pathological slice reveals two people’s red blood cells, clinically speaking, what could be the cause?" Dr. Yuan inquired, concerned less about whether he was interrupting Professor Yang’s ti, for any mishandling could impact the case evaluation.
"I don’t know forensic dical knowledge, so everything I say is rely based on the judgnts derived from foundational and clinical dical knowledge: there are only two possible sources for the deceased’s heterologous red blood cells. The first is a dical action—blood transfusion, yet a normal transfusion doesn’t cause the infused blood to form clots, and from your records, the patient has not received a transfusion. The other possibility is a non-dical action—soone extracted others’ blood and injected it intravenously into the deceased, with the introduced blood being processed to reach a critical state, it coagulates imdiately upon entering the deceased’s vessels, forming clots. These clots form free clots, circulate through the bloodstream to the heart, and then enter the pulmonary circulation. Continual emboli enter the pulmonary circulation, eventually causing pulmonary embolism, and these emboli then induce the body’s own thrombus formation, creating a vicious cycle that finally results in fatal pulmonary embolism."
"Actually, if it’s the latter, as long as no foreign red blood cells mixed into the clots are detected, the autopsy will surely conclude the deceased died from their own pulmonary embolism."
"If—I’m simply speculating here—if soone deliberately did this, it is an extrely clever murder thod."
"What I say next is re speculation, provided for your reference."
"You see, the patient has diabetes and needs to inject insulin subcutaneously into the abdominal wall daily. This serves as an excellent camouflage backdrop; amid such a large background, the appearance of nurous pinholes on the abdominal wall wouldn’t be surprising. For a healthy individual without an insulin injection history, any pinhole appearance on the body would certainly beco your focus, but for a patient needing multiple daily insulin injections, so pinholes on the abdominal wall, and if the pinholes match the insulin injection needle, you wouldn’t suspect anything."
"Moreover, if this patient died from air embolism, alcohol poisoning, hypoglycemia, or other foreign substances introduced into the body causing pulmonary embolism death, etc., all those situations would certainly draw your deep suspicion. Thorough analysis and testing could easily reveal the cause of death, yet only dying from clot-induced pulmonary embolism seems entirely normal to you—no suspicious circumstances whatsoever."
