Chapter 318 Tears of the Virgin Mary

Chapter 317 Plant Alkaloids

Outside the scene, Chen Yi and Lv Guangjun stood far away and exchanged information about the first case.

Taking the cigarette handed by Lv Guangjun, Chen Yi said: "Female? Tell me in detail."

As he said that, he raised his hand to light the cigarette.

Lv Guangjun recalled the case and told Chen Yi the process of Li Yao's murder and the current progress of the investigation.

Although he used relatively brief language, it was very detailed and did not miss any key points.

Chen Yi did not interrupt and listened carefully. When Lv Guangjun's voice fell, he asked about the point he was concerned about: "Wanting to jump off the building to commit suicide a week ago, it wouldn't be a coincidence, do you have a photo of the deceased now?"

Lv Guangjun: "Wait a minute."

He took out his mobile phone and opened the work group. After searching for a while, he showed Chen Yi the photo of Li Yao.

Chen Yi took a look and confirmed that it was the girl who jumped off the building when he was shopping with Fang Shuyu before. At that time, the firefighters and police had arrived and the person had been rescued.

"Chen Zhi, what coincidence did you just say?" Lv Guangjun asked.

Chen Yi explained: "I happened to see the suicide incident when I was shopping a week ago."

Lv Guangjun was surprised: "What a coincidence?"

Chen Yi nodded: "It is indeed a coincidence. I didn't expect that she would be killed in just a few days. However... from your investigation results, there seems to be no direct relationship between Li Yao's murder and Li Yao's suicide."

Lv Guangjun agreed: "It is indeed the case at present. It has nothing to do with it. I was just about to send someone to visit Li Yao's hometown to investigate. Unexpectedly, another one died, and two of them had the same crime characteristics. It can be basically determined that it was done by the same person, right?"

Chen Yi He hummed: "It's highly likely. How can it be such a coincidence? Since they didn't seek money, they must have a grudge."

Lv Guangjun: "I also thought it was a vendetta, but after checking the interpersonal relationships, there was no result. This is quite strange. Generally speaking, it is unlikely that there is no connection at all for a grudge like murder."

"It shouldn't be... a random killing, right?"

Chen Yi didn't make a hasty judgment. Not finding interpersonal relationships doesn't mean there really is no connection: "First, find the intersection of the two people, maybe there will be a breakthrough."

After the two chatted for a long time, Zhuo Yun finished his visit and returned to the cordon.

"Captain Chen." He came in front of the two.

Chen Yi: "Speak."

Zhuo Yun pointed to a place not far away and said: "The deceased had a meal at the second barbecue restaurant. There was only one person and drank about six bottles of beer. Because there was only one toilet, customers often had to line up, so many customers were used to going to the toilet here. The deceased should have died while going to the toilet."

Hearing this, Chen Yi looked around again to make sure there was no surveillance, only the restaurant had one.

"Drinking alone... Could he have been heartbroken?"

The thought flashed through his mind. At present, there were no clues. He would wait for the results of the forensic and trace examination investigations, and then determine the identity of the deceased and proceed step by step.

"Chen Zhi, is our branch team still involved in this case?" Lv Guangjun asked.

Chen Yi: "Do you have other cases?"

Lv Guangjun: "There are a few small cases, which are not a big problem."

Chen Yi: "Then follow the original plan and visit Li Yao's hometown to investigate and keep in touch. We can't miss any possibility. Also, the detailed files of Li Yao's case will be sent to the Municipal Bureau tonight. Hurry up."

Lv Guangjun nodded: "Okay, Chen Zhi, then I will go back and make arrangements first?"

Chen Yi: "Yes."

The Criminal Investigation Team left, and only the Criminal Investigation Detachment was left at the scene.

When the remaining traces were almost extracted, Chen Yi and Zhuo Yun walked over.

"Team Chen, isn't Deputy Captain He here?" Zhuo Yun didn't see any trace of He Shixin.

Chen Yi: "There is no need for so many people. Let him have a good rest first. In case it is a complicated case, he needs to change shifts." As he said this, he came to the body, and the forensic doctor was still working. Without waiting for Chen Yi to ask, Fang Shuyu, who was wearing a mask, looked at the body and said: "He has just died for two to three hours. Unknown rashes are clearly visible on the skin. There are small pinholes on the side and back of the neck. Apart from this, no other scars have been found for the time being." "The abnormal secretion of saliva is extremely large, like poisoning. The specific details need to be returned to the Municipal Bureau for toxicological tests." Lu Guangjun just said that the first victim, Li Yao, was poisoned. In this way, the possibility of the same murderer is further confirmed. "Is the mobile phone here?" Chen Yi asked. Fang Shuyu: "Yes, there is only a mobile phone on my body, no other items." Unless it is necessary, few people carry ID cards with them now. A mobile phone is enough. Chen Yi: "Prepare to withdraw the team and go back to confirm the identity. Brother Yun, you lead the team to search far away for suspicious items, especially syringes."

It is possible that they threw away the person after killing him. Although no one found it at the scene where Li Yao was killed, it does not mean that there will be no such thing this time.

Zhuo Yun: "Yes."

Chen Yi looked at Jiang Xiaoxin again: "Jiang Jie, check the surveillance and pay attention to those who wrap themselves tightly."

Jiang Xiaoxin: "Understood."

The forensic doctor and the trace examiner returned to the Municipal Bureau, and Chen Yi followed them and left. The scene was handed over to Zhuo Yun for command.

Another night was to be spent.

Because the soil at the scene was soft and there were so many guests going to the toilet, there were many messy footprints left, which needed to be identified one by one.

Chen Yi provided Lu Yongqiang with a height of 1.78 meters for screening.

As long as the footprints were locked, the gender and weight could be determined, excluding the low probability events.

While waiting, Chen Yi sat in the case handling hall, looking through the case files of Li Yao sent by the branch, and had a clearer understanding of the whole process.

"Poisoning."

"All acquaintances have been ruled out as suspects."

"Not seeking money."

"Not seeking sex."

After a long time, Chen Yi closed the file and said to himself: "Old Lu is a bit of a jinx. If this is a random killing, it will be difficult to deal with, but... preliminary exclusion of suspicion does not mean complete exclusion of suspicion."

At this time, Lu Yongqiang left the technical department and came to the case handling hall to report the results of the footprint screening to Chen Yi.

"Found it, there are indeed footprints that match the height of 1.78 meters, and the weight is about 70 kilograms. It is very likely to be a male."

"No fingerprints were extracted from the pendant, and it was clean and looked like new."

Chen Yi took the report, and the trajectory of the footprints had been marked.

"Male? Very standard weight."

Choosing poisoning, he thought about the possibility of a female murderer, and did not dare to confront the victim head-on, because his physical fitness did not allow it.

Lu Yongqiang nodded: "Yes, it is relatively standard, and the body fat percentage should be excellent."

Chen Yi remembered this information as one of the bases for criminal profiling.

Either he has been engaged in physical work for a long time, or he has the habit of fitness.

Choosing to poison with a syringe and adding sedatives is very well considered. He looks like an intellectual, not a rough worker.

In terms of probability, he tends to have the habit of fitness.

"Chen Yi, come here." Fang Shuyu's voice came from the forensic department.

Chen Yi stood up: "Brother Qiang, you go back and rest first. The identity of the deceased will be determined at dawn."

Lu Yongqiang: "Okay."

When he arrived at the forensic room, Fang Shuyu informed him of the results of the toxicology test and the possible source of the poison, and confirmed that there were no other scars on the body of the deceased except the needle hole left by the syringe on the neck.

There are sedatives in the blood.

Combined with the footprints, it can be judged that the murderer attacked from behind and instantly made the victim unconscious.

"Alkaloids? Which alkaloids?" Chen Yi asked.

Fang Shuyu shook his head: "It's not clear yet, the concentration is very high."
