"Preliminary estimates suggest that the cause of death of the deceased was suffocation. Qiu Lan gently moved the deceased's hand around his chest, exposing his neck.

Hearing her words, a trace of doubt crossed Xu Chengyan's eyes, "Suffocated to death?"

"That's right!" Qiu Lan nodded firmly, her voice cold, "The deceased's lips are cyanosis, pupils are dilated, and eyelid bleeding are typical symptoms of suffocation. ”

"But. Xu Chengyan lengthened the end note, and his gaze stayed on the bloody broken neck.

Qiu Lan understood his question.

Any person who sees such a scene may have doubts about the judgment of suffocation, but science is science, and she trusts her professional judgment.

"Officer Xu, the wound on the neck was caused by the deceased after he had suffocated to death, because the wound showed no signs of healing. ”

"So I'm sure that the deceased's neck was cut off after death, and as for the specific report, I will go back to the laboratory to test the platelet content in the blood stains on the deceased's neck. ”

"Okay, I'm sorry for Dr. Qiu. Looking at her firm eyes, Xu Chengyan dispelled the doubts in his heart, the expression on his face gradually solidified, and a meaningful light appeared in his eyes.

"And what is the possible modus operandi?"

Qiu Lan lowered her eyes, was silent for a second or two, and after thinking, she replied, "Thin wires, metal wires with a diameter of less than two millimeters, such as iron wire, copper wire. ”

"Because the red strangulation marks on the neck of the deceased are very fine, the marks are only about one millimeter. ”

"Pei Pei, go and tell Expert Cao, and ask them to pay attention to the thin wire and the metal wire less than two millimeters in diameter when collecting evidence, which is likely to be the murder weapon that killed the deceased. ”

Xu Chengyan, who had a serious face, glanced sideways at Pei Pei beside him and gave the order.

"Good. After Pei Pei heard his words, he immediately turned around and walked towards Cao Fan and told him Qiu Lan's judgment.

At the same time, Qiu Lan took out a slender liver temperature detector from the box and slowly inserted it into the liver part of the deceased's body, and the pointer on the dashboard turned a few times.

"Thirty-two degrees, an hour before the time of death?" Qiu Lan dragged out the last note, with a hint of doubt in her voice.

"What's wrong?" Xu Chengyan looked at her expression and asked suspiciously, "Is there anything suspicious?"

Listening to his question, Qiu Lan did not respond to him immediately, but lowered her eyes, lowered her head and pondered for a moment, her eyes dim.

"On the back and legs of the corpse, there were many light purple corpse spots, all of which were present two to four hours after the death of the human body, but the liver temperature showed that the death was only one hour. ”

She told Xu Chengyan about the doubts in her heart, and pursed her lips lightly.

"And there are many small traces of corruption on this corpse, that's why there is such a strong smell, but these shouldn't be now?"

"The time is not right?" Xu Chengyan frowned, his expression solemn, "Could it have something to do with the corpse soaked in gasoline?"

"Possibly. Qiu Lan nodded thoughtfully, "However, it's not the gasoline that is the problem, it's that the gasoline contains other ingredients that will affect our judgment of the time of death of the deceased." ”

"Officer Xu, I have already asked Expert Cao to collect evidence, and I will not be able to give you the specific time of death until the test results from his side come out. ”

"Good. Xu Chengyan nodded and responded softly, "We will first investigate the deceased's family background to see who he has a grudge with." ”

He glanced at the bruises on the corpse, and echoed what Qiu Lan had just said, his eyes sank.

"With so many injuries caused two hours before death, maybe the person who did the work with the deceased was the murderer of the deceased. ”

"I agree. Qiu Lan moved her eyebrows and nodded slightly.

"The extra scars on the deceased's body were almost instantaneous, and the person who hurt him must have dealt a heavy blow. ”

Generally speaking, if the injury is only minor, only subcutaneous bruising will form within 24 hours, and it will only be visible under ultraviolet light.

However, the traces on the deceased's body were shown early on, and the force of the blow could be said to be able to fracture the fingers of the human body.

Therefore, Qiu Lan still suspected that there were other scars inside the deceased's body.

"Officer Xu, the simple situation is what I told you just now, as for the rest, I won't be able to report to you until I have dissected it. ”

With a serious face, Qiu Lan took off her goggles and mask, and a blush on her face was clearly visible.

As soon as Xu Chengyan, who was standing next to her, saw the scars on her face, a trace of concern and worry crossed his eyes.

At this moment, Mo Heng, who had been searching for the garbage heap, walked over to them quickly, looking hurried.

"Doctor Qiu, Officer Xu, I found it. She came over with a sealed evidence bag and a cotton swab that had been glowing purple and pink.

"According to what Dr. Qiu said just now, I found a rusty copper wire with a red and black mark on it, I verified it, it was a blood stain reaction. ”

Rusty copper wire?

Qiu Lan took the evidence bag in her hand and looked at the evidence inside rigorously and carefully, the diameter and size were indeed less than two millimeters, and the length was enough to strangle a person.

"But. She frowned, her lips pursed into a straight line, "This is not a murder weapon for strangling the dead." ”

"There are green traces on this copper wire, and the composition is copper oxide, which means that the copper wire is rusty. ”

"But when I examined the strangulation marks on the neck of the deceased, I did not find any traces of patina, and I found no traces of copper oxide on the wounds on the deceased's neck. ”

"What about this copper wire?" Xu Chengyan sank his eyes, his eyebrows were deep, "Could it be that there is another deceased?"

"Don't be so afraid. Qiu Lan raised the corners of her mouth lightly and furrowed her brows, "It's also possible that someone was injured and strangled by this copper wire." ”

Hearing her words, Xu Chengyan nodded.

I don't know why, when he saw the shallow smile on the corner of Qiu Lan's mouth, he couldn't help but show a hint of a smile.

The cold atmosphere was instantly warmed up a lot.

"Anyway, this copper wire still has to be brought back for testing. He glanced at the forensic officer beside him, and his voice was flat, "Mo Heng, where this copper wire was found, you can check it again." ”

"Thank you for your hard work, this place is really a lot of work for you today. ”

"It's okay, that's what we do, and it's not like we haven't searched the dump before. Mo Heng pursed his lips and responded, then turned around and walked towards the garbage heap.

At seven o'clock in the evening, the sun sets, and the golden glow spreads all over the garbage dump.

The forensic department's work to collect evidence continues, but Qiu Lan has already preliminarily examined the body, and will only wait for tomorrow to dissect the body.

Satoshi led the body to the transfer cart, and she was ready to leave.

However, just as Qiu Lan walked in the direction of parking outside the cordon, a beautiful supercar fell into her eyes.

That's Li Shanghan's car!
