While Liang Shi and the others were investigating the site of the Longwan Project's opening ceremony to contain clues, technicians also conducted an on-site inspection of the body in an orderly manner. After several hours of intense work, the body was finally put into a body bag and prepared to be transported back to Zhongjiang City for evidence.
The identification center will do further dissection.
Chen Bochao, a senior forensic doctor in Zhongjiang City, took off the rubber gloves that were stuck to his hands, took the cigarette handed over by Liang Shi and held it in his mouth. He let Liang Shi light it and took a deep breath before taking it off his lips.
He smoked a cigarette and exhaled the turbid air for a long time. At this time, his fatigue seemed to be slightly relieved.
"How are you, Old Chen? Can you give me a preliminary conclusion?" Liang Shi asked beside him.
Chen Bochao turned his head and glanced at Liang Shi, then at Xu Wen beside him, and returned his solicitous eyes to Liang Shi's face. Liang Shi understood what Lao Chen meant, and reached out to pat Xu Wen's shoulder.
explain:
"It's okay, Old Chen, tell me, although Xu Wen is not a member of our criminal police, he is still half a member of the task force."
"Well, okay then." Chen Bochao exhaled a puff of smoke again and said:
"There were no serious injuries on the two corpses. There were only deep strangulation marks on the necks. It was suspected that they had been strangled to death. There were several scratches on other parts of the body, which were suspected to have been caused when the bodies were transported after death.
Caused."
"Can the time of death be determined?" Liang Shi asked.
"We found that the body had been refrigerated at a low temperature after death. At present, it is initially estimated that the time of death was at least 2 days. The specific detailed data cannot be determined until the autopsy is performed."
"More than two days? That means Lao Zhuang and Li Ping were killed after getting into the black car." Ma Yan, who was standing aside, interrupted at this time.
"When was the last time you saw the deceased?" Forensic Doctor Chen asked.
"At 11:35 noon the day before yesterday, we saw Lao Zhuang and Li Ping getting into a black car with a brand name." Ma Yan glanced at Xu Wen as she spoke.
"Okay, this time point is very important, it is very critical for us to judge the time of death." Forensic Doctor Chen nodded and said.
"Are there any other discoveries at the scene?" Liang Shi asked.
"We checked the bucket of the excavator, which can be said to be spotless. According to reports, this excavator has never been used. The body rolled from the bucket of the excavator and fell to the ground. The side that touched the ground was covered with dirt.
There is dirt on the body, but the top of the body is very clean. This shows that someone killed the deceased elsewhere, used a transport vehicle to transport it here, and threw it directly from the car into the bucket."
"Well, it makes sense. This means that there must be at least 2-3 people involved in dumping the body. In addition to the work of dismantling and reinstalling the fence, I don't think they can complete it without three people." Liang Shi said.
"We also found a clue in the body and the bucket, which may be helpful for future investigation work," said forensic doctor Chen.
"Oh, tell me quickly, Old Chen, what's the point?" Liang Shi asked anxiously.
"Don't worry, I'm wondering why this happened."
"Wouldn't it be better if you say it and everyone thinks about it together?" Liang Shizhen was a little anxious.
"Well, it's like this. We found a very fine and light gray-black powder in the bucket and on the body. I guess this powder should have been brought into the bucket from the body, which means that the body was entering
The bucket has been in contact with these powders before." Forensic Doctor Chen said mysteriously.
"What kind of powder is it?" Liang Shi asked.
"It's not easy to judge yet. The powder is very fine. I have to go back for identification to confirm my conclusion." Lao Chen put on a showy look.
"Please tell us first." Liang Shi said anxiously.
"No, if I say something wrong, it will affect the direction of your investigation. This is very fast. I can get the results in about an hour after I return to the center." Forensic Doctor Chen shook his head and insisted.
"Okay, I can't defeat you." Liang Shi shook his head and replied helplessly.
While Liang Shi, Ma Yan and forensic doctor Chen were discussing the case, Xu Wen was listening to their conversation while facing the opened fence and thinking about something.
"What's wrong Xu Wen? What are you thinking about?" Liang Shi asked looking at his focused look.
"Ah, I'm thinking about a question." Xu Wen answered subconsciously.
"What's the problem?" Ma Yan also came over and asked.
"I'm wondering how they nailed the color steel plates inside?" Xu Wen replied.
"Is there any problem? Tell me." Liang Shi said.
"The fence is double-layered. There is a 5cm square steel sandwiched between the inner and outer color steel plates. The color steel plates are fixed on the middle square steel from both sides. Do you think the inner color steel plates can be nailed from the outside?
"?" Xu Wen asked.
"Isn't this impossible?" Ma Yan said.
"You mean, how do people leave after fixing the color steel plate from the inside?" Liang Shi asked, staring at Xu Wen.
Xu Wen nodded and continued:
"The height of the fence is 2.4 meters, and there is no guarantee that you can climb it without damaging the color steel plate. The bottom of the fence is close to the ground and there is no space to get out. How do people get out?"
"Well, that's a problem." Liang Shi held his chin in one hand and fell into thinking.
"Is there an insider?" Ma Yan asked tentatively.
"There must be an internal response, otherwise how would they know that the three excavators should have the same shape?" Xu Wen said.
"No, Xu Wen." Liang Shi suddenly shouted:
"You only considered half of the problem. Have you ever thought about how they removed the inner color steel plate?"
"Yes, they have to bring in one person first to remove the color steel plate on the inside. After they finish dumping the body, this person will then install the color steel plate." Xu Wen said.
"That is to say, the internal agent should have been in the hospital last night." Ma Yan said.
"Well, if we can't find other entrances and exits, we can be sure that one of the people in the hospital must be an insider." Liang Shi said.
"Then bring back all the people who were on duty last night for interrogation."
"Don't worry, we have controlled them all and arranged for people to inquire individually. Let's check the fence again to see if there is a place where people can enter and exit," Liang Shi said.
After greeting Bian Xingxue and his men, a group of personnel once again conducted a more careful inspection along the fence, focusing on looking for signs that the fence had been stepped on or bent, and whether there were any holes under the fence that could allow people to get into.
An hour passed. Chen Bochao had already left with his technical staff. Liang Shi and Xu Wen were still carefully surveying along the fence. After everyone had walked along the fence, everyone gathered together.
Looking at everyone silently, they don't know whether this result is good or bad for them?
