Chapter 1512 Sample Examination, Verification of Clues from On-site Investigation
"Understood, Teacher Zhang!" Xiao Lin quickly replied, walked briskly to the sample storage area, picked up two sterile test tubes and a sterile pipette, and carefully walked to the dissection table, handing them to Zhang Lin. Zhang Lin took the test tubes and pipette, gently drawing blood and turbid fluid from the abdominal cavity, injecting them into the two test tubes respectively, and then handed them to Xiao Lin.
Xiao Lin took the test tubes and carefully placed them on the sample tray. He picked up a marker and clearly labeled the tubes with the following information: "Unidentified male corpse, blood sample from the abdominal cavity, extraction location: middle of the deceased's abdominal cavity, extraction time: 11:40 AM today" and "Unidentified male corpse, turbid fluid sample from the abdominal cavity, extraction location: middle of the deceased's abdominal cavity, extraction time: 11:40 AM today." After labeling, he neatly arranged the test tubes on the sample tray and said softly, "Teacher Zhang, the samples have been extracted, labeled, and arranged neatly."
Zhang Lin nodded, his gaze returning to the internal organs in the abdominal cavity. Using sterile tweezers and hemostats, he carefully combed through the internal organs, examining the position and shape of the liver, spleen, stomach, small intestine, large intestine, pancreas, kidneys, bladder, and other organs one by one, not missing a single detail.
"Liver: Located in the upper right abdomen, normal in shape, approximately 25 cm x 15 cm x 8 cm in size, dark red in color, smooth surface, no rupture, no bleeding, no contusion, no pathological changes such as tumors or cirrhosis, soft in texture, consistent with the characteristics of a normal liver." Zhang Lin reported slowly while examining the liver. "Spleen: Located in the upper left abdomen, normal in shape, approximately 12 cm x 7 cm x 4 cm in size, dark red in color, smooth surface, no rupture, no bleeding, no contusion, soft in texture, no abnormal enlargement, consistent with the characteristics of a normal spleen."
"Stomach: Located in the upper middle abdomen, it is empty. The stomach wall is about 0.5 cm thick, the gastric mucosa is smooth, and there is no bleeding, ulceration, or perforation. A small amount of stomach contents can be seen in the stomach cavity, mainly undigested rice and vegetable scraps. There is no odor or abnormal color. It is necessary to extract stomach contents samples for toxicological testing and digestion analysis to help estimate the time of death. At the same time, we need to investigate whether the deceased showed signs of poisoning."
"Small intestine and large intestine: normal in shape, no rupture, no bleeding, no contusion, smooth intestinal wall, no abnormal contents in the intestinal lumen, no pathological changes such as obstruction or perforation, consistent with normal intestinal characteristics; Pancreas: located in the upper middle abdomen, normal in shape, about 15 cm x 5 cm x 2 cm in size, pale yellow in color, smooth surface, no bleeding, no contusion, no pathological changes such as pancreatitis; Kidneys: both kidneys are normal in shape, about 11 cm x 6 cm x 3 cm in size, dark red in color, smooth surface, no rupture, no bleeding, no contusion, no pathological changes such as stones or tumors, the renal parenchyma is uniform in texture and has no abnormalities; Bladder: empty, bladder wall is smooth, no bleeding, no contusion, no pathological changes such as stones or tumors; both adrenal glands and ureters are normal in shape and have no abnormal lesions."
Xiao Lin listened attentively and took notes rapidly, his pen barely stopping. He wanted to ensure that every detail mentioned by Teacher Zhang was accurately recorded to provide a complete and accurate basis for the subsequent autopsy report. "Teacher Zhang, all notes have been taken. Most of the internal organs in the abdominal cavity are normal in shape, with no abnormal lesions, injuries, or bleeding," Xiao Lin reported softly after finishing his notes.
Zhang Lin nodded, his gaze refocusing on the wound area on the left side of the deceased's abdomen. His tone became more serious: "Alright, most of the internal organs are fine. Next, we will focus on observing the damage to the internal organs corresponding to the abdominal wound—this is the core of this abdominal autopsy and the key to confirming the cause of death."
As he spoke, he carefully used sterile tweezers and hemostats to gently separate the tissue around the wound, focusing all his attention on the internal organs corresponding to the wound. As the tissue was slowly separated, the depth and extent of the injury became clearer. The wound penetrated from the skin, subcutaneous fat, rectus abdominis muscle, transverse abdominis muscle, peritoneum, all the way into the abdominal cavity, reaching a depth of about 8.5 centimeters. The injury was mainly concentrated on the left side of the abdomen.
The internal organ corresponding to the wound is the spleen. On the surface of the spleen, there is a puncture wound that is completely consistent with the location, size and shape of the wound on the abdominal surface. The puncture wound is about 5 cm long and about 1 cm wide, with neat and smooth edges, consistent with the characteristics of the wound on the body surface. Obviously, this was caused by the same single-edged sharp weapon.
Significant bleeding was observed within the spleen parenchyma, covering an area of approximately 3 cm x 4 cm. The spleen capsule had ruptured, and a large amount of blood was flowing out from the rupture, accumulating in the abdominal cavity and forming hematometra. Zhang Lin gently touched the ruptured area of the spleen with sterile forceps, feeling the texture of the spleen, and then said softly: "Xiao Lin, record: The abdominal wound is approximately 8.5 cm deep, penetrating the abdominal wall (skin, subcutaneous fat, rectus abdominis muscle, transverse abdominis muscle, peritoneum) and entering the abdominal cavity. The injury is mainly concentrated on the left side of the abdomen; the internal organ corresponding to the wound is the spleen. A puncture wound is visible on the surface of the spleen, consistent with the location, size, and shape of the wound on the abdominal surface. The puncture wound is approximately 5 cm long and 1 cm wide, with neat and smooth edges, consistent with the characteristics of a single-edged sharp instrument puncture wound; there is significant bleeding within the spleen parenchyma, covering an area of approximately 3 cm x 4 cm, and the spleen capsule has ruptured, resulting in hematometra, mainly originating from the spleen injury."
After a pause, Zhang Lin said firmly, "Based on the abdominal autopsy, the cause of death has been further confirmed: the deceased was stabbed in the abdomen by a single-edged sharp weapon. The wound penetrated the abdominal wall, punctured the spleen, causing spleen rupture and massive bleeding. Approximately 200 ml of blood accumulated in the abdominal cavity. The massive splenic hemorrhage triggered acute hemorrhagic shock, ultimately leading to the deceased's death. Poisoning, mechanical asphyxiation, craniocerebral injury, and visceral organ lesions have been ruled out as other possible causes of death. The deceased's only fatal injury was a single-edged sharp weapon stab wound to the left side of the abdomen."
Xiaolin quickly took notes, and her mind became clearer—the initial assessment was correct; the deceased's fatal wound was indeed a stab wound to the abdomen from a single-edged sharp weapon, leading to a ruptured spleen and acute hemorrhagic shock. "Teacher Zhang, the notes are complete. The cause of death has been confirmed and is consistent with the initial assessment. Other causes of death have been ruled out."
“Okay, next, extract one tissue sample from the spleen injury area and one sample from the spleen hemorrhage,” Zhang Lin continued. “Using a sterile scalpel, take a piece of tissue from the spleen injury area, about 0.5 cm x 0.5 cm x 0.2 cm in size, and place it in a sterile tissue specimen bottle, labeling it with relevant information; use a sterile pipette to extract a small amount of spleen hemorrhage sample, place it in a sterile test tube, label it with relevant information, and then send it to the laboratory for pathological examination to confirm the degree of spleen damage, the time of bleeding, and whether there are other pathological changes, further corroborating the cause of death.”
