The forensic wife is very nice to me

In the laboratory of the criminal investigation building, under bright lights, colleagues from the forensics department, Qiu Lan and Xiao Cong opened all the evidence boxes together, and all the evidence bags inside were neatly placed on the table.

"Expert Cao, you are responsible for the identification and comparison. I will focus on the items brought back from the scene related to the wounds on the dead woman's body." Qiu Lan frowned slightly, her expression calm.

"Okay." Cao Fan nodded solemnly.

After that, they carried out a simple classification of many items, and the forensic and forensic departments began to search for different targets.
In front of the evidence table, Qiu Lan put on dust-proof white gloves and goggles, and carefully picked up the first piece of evidence, "Xiao Cong, make a record, this is a wooden baseball found in the suspect's home." stick."

"The shape and force of the baseball bat match the No. 13, No. [-], and No. [-] wounds on the deceased woman's body, and the defensive scars on the deceased's arm are also likely to be caused by the baseball bat."

The meticulous Qiu Lan carefully took out the baseball bat in the sterile space, and her sharp eyes fell steadily on the bat, "There are cracks on the surface of the bat, if the deceased was really hit, the cracks There is a high chance of residual sebum."

After she finished speaking, she picked up the hooked tweezers on the side and carefully inspected every crack. Near the head of the stick, she found two thin light yellow transparent tissues.

"This is the skin surface tissue of the human body." She put the two strips into two different glass dishes and sealed them well, "Xiao Cong, give this to Expert Cao, he should be able to extract to DNA for comparison."

"Okay." Xiao Cong nodded solemnly, and handed the things to Cao Fan who was doing comparison in the appraisal room.

In the following time, Qiu Lan scanned and inspected more than a dozen other items found at the scene, but they were not in line with the case in terms of shape, strength, and degree of wear and tear, so they were all excluded one by one. up.

An hour later, Cao Fan and Henry Mo from the forensics department came out of the appraisal room with a few documents, "Doctor Qiu, we have the results."

With a heavy complexion, Cao Fan handed Qiu Lan a copy of the appraisal report, and Shen Leng said, "In the home of the suspect Li Gang, we found a hair comb with women's hair on it. There are two different groups of hair. genes, one of which is male genes."

"And the other group is the genes of the female deceased."

"The gene of the dead woman was found in his home, so Li Gang can no longer deny that the dead woman appeared in his house, and the argument of bringing the woman home is useless." Qiu Lan wrinkled thoughtfully. He frowned and pursed his lips lightly.

She lowered her eyes, silently thinking about all the clues she found.

"Now it seems that there may be a necessary connection between the death of the female deceased and him. Expert Cao, has the test result of the sample you took in the pool come out? How about the comparison?"

"Doctor Qiu, this is a suspicious point." Cao Fan took out another document and scanned it with keen eyes. "I compared the pleural effusion of the deceased with the pool sample obtained from the suspect's home."

"There is a big difference between the two. I can conclude that the deceased did not drown because of the water in the pool."

"I didn't drown in the water in the pool, so where would it be?" Qiu Lan lowered her eyes, tapped her jaw thoughtfully, and murmured in a low voice.

Xiaocao's body was found in the sea, and it happened to coincide with a capsized ship, and the helm of this ship was from the same company as Li Gang, which proved that this method can be used to dump the body Someone must be well aware of the news in this regard.

The female deceased, Xiaocao, was a bereaved orphan, and not many people knew about her. Under such circumstances, the police found information about the deceased female's life at the suspect's home.

Coupled with the testimony provided by the security guard eight years ago, this series of evidence was all attributed to Li Gang, and Qiu Lan was very sure that Xiaocao's death was inseparable from that short and fat man.

Further reasoning, the corpse was handled very covertly. If the boat had not capsized and was discovered, Xiaocao would have been thrown into the sea without anyone knowing.

After thinking about it, Qiu Lan couldn't think of a better crime scene than Li Gang's home.

With a dignified expression, Qiu Lan carefully flipped through the documents in her hand, and the information from the crime scene and the results of the autopsy kept echoing in her mind.

Suddenly, she thought of a small fish tank in the corner of the hut. Although there was no water or fish in it when they went there, there were still many freshwater aquatic plants living in the crevices of the stones.

The fish tank had a diameter of thirty centimeters and a depth of nearly forty centimeters. This size could completely submerge a person's head.

"Expert Cao, I figured it out." Qiu Lan raised her eyebrows, her eyes shone brightly, "I checked the pleural effusion and the fluid in the lungs of the deceased during the autopsy."

"But because it was discovered in the sea, I didn't doubt the content of some plant particles in it at all, but now that I think about it, those plant particles may have been taken away in the fish tank."

Qiu Lan raised her eyes, stared at the person in front of her seriously, and said solemnly, "Expert Cao, I think there is crown grass in that fish tank, and crown grass will have seeds floating, if we find it in the pleural effusion That's it, that's the result."

Hearing her words, Cao Fan suddenly realized, and immediately understood the deep meaning, "Yes, crown grass is a freshwater creature, and it cannot exist in the sea."

After some processing and chromatography, Henry Henry put the sample of the female deceased's pleural effusion into the analyzer, while Qiu Lan and Cao Fan waited in front of the computer.

After 10 minutes, the progress bar got closer, and the result was ready to come out.

90.00% nine, one hundred percent.

The results were clearly displayed on the screen, and a variety of marine microorganisms and a small amount of seeds of the freshwater organism Crown Grass were found in the pleural effusion of the deceased female Xiaocao.

"Great, there are indeed seeds of Crown Grass." Henry hooked the corners of his mouth, with a slight smile on his face.

However, Cao Fan, who was standing beside him, still frowned with a solemn expression, "However, this evidence does not completely prove that the female deceased was drowned in Li Gang's fish tank."

"That's right." Qiu Lan nodded in agreement, her brows twitching slightly, "Crown grass is a freshwater creature that many families choose to raise in fish tanks, and it is very common, so this evidence can only provide us with clues, but it cannot directly The fish tank that proves where the death scene of the deceased is."

After listening to the analysis of the two experts, the other forensic personnel were unavoidably a little disappointed. They thought that with this evidence, the murderer's charges could be confirmed, but they didn't expect it to be a little bit worse.

But at this moment, Qiu Lan thought of another piece of information on the autopsy report.

That message might open new horizons.
