ICS Homicide Tracking

Before Shi Han left the laboratory, he took off his white coat and gloves, and walked over with a handwritten report.

Seeing this, Li Qi stepped forward and asked, "What's the matter? What's the result?"

Shi Han looked at the experiment report and said, "There is indeed a trace amount of cardiac glycosides in the bottle, but the amount is not enough to be fatal. Afterwards, the Department of Physical Evidence conducted an identification on the bottle cap and confirmed that the cardiac glycosides on the bottle cap have a higher purity. , and there are old stains, it was poisoned many times, but there is still no direct evidence.”

Li Qi heard that after thinking for a while, he took out another box and said, "Just now someone brought them back from the hospital, you can see what you can use."

I heard from the new cleaner, Xiao Chen, that the previous cleaner decided to leave on a temporary basis, so he took away his belongings and left the rest in the cleaning room. They tried to get in touch with the previous cleaner, but the phone kept calling. No one answered, so they assumed that these things were unwanted, so they brought them all back.

Shi Han took another glove from the side and carefully collected evidence, but there seemed to be nothing unusual about these things.

Yan Ran didn't have gloves and couldn't use his hands, so he could only sit aside and watch. Seeing that Shi Han's clothes were dirty, he reminded him, "Shi Han, let me get you a white coat, your clothes are all dirty."

When Shi Han heard this, he immediately lowered his head to check, and saw that his dark coat was stained with white powder at some point. He immediately obtained the evidence and had someone send it to the Physical Evidence Department for testing, and then checked all the physical evidence again. The white powder was in the end Where did it fall from, is it oleander pollen?

Not long after, Yuan Xin poked his head out of the laboratory before taking off his gloves, and shouted outside: "This? It's oleander pollen, where did you get it?"

Hearing this, Shi Han directly sent the evidence box into the laboratory and asked Yuan Xin to find the source of the powder.Then he was about to return to the office area, but just after taking two steps, he frowned at the material on his coat and turned back to the morgue.

"What's wrong with him?" Li Qi pointed to the strange Shi Han and looked at Yan Ran.

Looking at Shi Han's panicked back, Yan Ran immediately understood what he meant, and said to Li Qi: "Captain Li, you guys chat first, I'll send him clothes."

Fortunately, he had put a piece of casual clothes in Shihan's office before, otherwise I don't know what Shihan and the others will wear.

"The clothes are at the door for you!" Yan Ran put the clothes in a clean place, took another bag to put away the dirty clothes, and prepared to take them home for washing.

Shi Han responded, and before he could say thanks, he heard Yan Ran's slight struggle outside, immediately turned off the shower, dried his body, left the bathroom, put on everything very quickly, and went out to look for Yan Ran, I saw him shrinking in a corner with a face of resistance.

"What's the matter?" Shi Han asked softly, then he turned his head to look at the clothes at the door of the shower room, understood something instantly, and immediately asked, "Did you touch oleander powder? Are you feeling uncomfortable now?"

Yan Ran clenched her teeth, shook her head and said, "I can still hold on. Shi Han, I seem to have succeeded, and I will no longer be suddenly controlled by these memories."

But after all, now there is a kind of force that is colliding with his psychological defense and eating away at his sanity.Yan Ran tightly grasped Shi Han's hand, even if he didn't say a word, the sweat on his forehead had already revealed his suffering at the moment, he said in a deep voice, "Take me out first!"

This is the morgue, if he loses consciousness here, there is no guarantee that there will be no accidents later, so he cannot faint here.

Shi Han nodded, regardless of the clothes that fell on the ground, he quickly carried Yan Ran out, and carefully placed him on the sofa in the office, "Okay, don't hold on anymore, let's go to sleep!"

Seeing such uncomfortable Yan Ran, Shi Han also felt his heart being grabbed, and patted his back lightly, seeing that Yan Ran's breathing gradually became even, Shi Han cleaned up the mess and went out to take Wen Xu with him. came in.

Wen Huan carefully checked Yan Ran's brain waves and electrocardiogram, and found that he was still in good health and had not been greatly affected, which made Shi Han feel relieved, now it is obviously Shi Han who is mentally affected.

Shi Han sighed, walked out of the office with Wen Huan, and then asked aloud: "Has the physical evidence come to fruition?"

Wen Huan nodded, "Captain Li is planning to find you. The physical evidence found oleander powder on a towel. They are now planning to scrape the powder off the towel. It is said that the weight is already quite large, and it can almost be convicted gone."

Wen Wen said, then paused, he turned back to his office, and took out a stack of psychological evaluation reports, he was puzzled now, why would a cleaning staff who had nothing to do with the deceased take such a risk? Big risk to kill?

Before the news of Yuan Xin's final confirmation came out, the investigation department and the network department had already set their sights on the last cleaner. Even if he was not the mastermind, he must be involved.

"Tu Ou, a native of City A, started training at the Municipal People's Hospital in August, and resigned in late September. There is no bad record on file." Zhou Xiaofan said, searching again, but found something strange again, "Tu Ou wants another job? He is currently working in a cleaning company and has not left."

Li Qi's staff immediately mobilized and rushed to the cleaning company to stop Tu Ou who was about to get off work, and brought him back.

"Officer, I haven't committed any crime! Why did you bring me here?" Tu Ou looked innocently at the head of the police officer who entered the door. He just got off work and was brought here by a group of police officers. He sat here for a long time, Also? Nobody told the reason for bringing him here.

Li Qi sat opposite Tu Ou, and asked in a cold voice: "A murder case occurred in the Municipal People's Hospital. The suspect is a cleaning staff on the patient's floor. His name is also Tu Ou, and the information also shows that you started working in August. People's Hospital."

"Police...Police officer, I really didn't do it!" Tu Ou quickly denied it, and then hurriedly organized his words, saying: "Police officer, I did submit my resume to the People's Hospital, but the hospital didn't reply me, so I thought I wasn't accepted. I was selected, so I went to the cleaning company, someone must have pretended to be me!"

He's still in the fog until now, he didn't do anything? Did he take the blame for not doing anything?This? Can't do it!

Seeing the situation, Li Qi immediately had two cleaners from the 12th floor of the hospital's inpatient department called over. The two identified separately, but they both said that they had never seen this Tu Ou in the interrogation room.

"Strange!" Li Qi scratched the back of his head, adding an extra thought, and asked the two of them to help make a portrait of "Tu Ou" they had seen before. Compared with this, it is indeed completely different from the Tu Ou they brought. Same.

Zhou Xiaofan imported the "Tu Ou" on the portrait into the big data, and compared all the faces in the database with the portrait one by one, and those with a high degree of overlap were included in the human eye recognition list.

Li Qi walked back and forth behind Zhou Xiaofan, why did he think this? There were more and more mysteries in this case, and they couldn't be solved no matter what?

Yuan Xin is still in the laboratory, Yan Ran is still sleeping, Shi Han and Wen Huan are doing the final psychological profiling of the criminal, Zhou Xiaofan's computer is running, it seems that they are very close to the truth, but they can't get away Where did they miss the truth?

As soon as Yuan Xin came out of the laboratory, he looked around. After finding Li Qi, he ran over and handed him a list, which estimated the amount of oleander powder in the towel, "Li Qi, the data It’s almost like this, you take it and tell your superiors first, and report that I will supply it to you immediately.”

They brought back Guo Teng's thermos cup, and extracted three sets of fingerprints from the lid of the thermos cup, one belonged to the owner of the cup, Guo Teng, and the other was left by Guo Yue when he closed the lid. They found the bed next to Guo Yue's. The fingerprints of the family members were brought back and paired with the third set of fingerprints, which proved that he had indeed opened this thermos cup.

In this way, this thermos cup is indeed Guo Teng's.Because no one knew that the vacuum flask had been opened except Guo Yue and his family members in the next bed, and the next bed was discharged a week earlier than Guo Yue, so he did not have the conditions to commit a crime.So they still set their sights on the water bottle.

Although the murderer took part of the powder from the towel, they still calculated the approximate data based on the distribution. This set of data is enough to cause a normal heart to beat too fast to die, and Guo Yue himself has a heart genetic disease, strong heart The glucoside attack occurred earlier than the murderer expected, so half of the amount remained on the towel.

"Screen out [-] portraits that match the portraits." Zhou Xiaofan said, uploading all the photos to the tablet, and took them to two cleaning staff for identification. The two looked at each other, saying that the "Tu Ou" they had seen was not here. on a few photos.

When Zhou Xiaofan returned to the office area, he shook his head at Li Qi, twisted his neck, and re-filtered the big data.

As soon as he sat down, there was movement in the psychological counseling room next to him. Wen Huan came out with a stack of papers in his arms, followed by Shi Han.Wen Huan looked at the notes on the paper, and said to Li Qi: "Shi Han and I reviewed the case again, and we probably have a profile of the murderer."

Wen Wen made an inference based on the available evidence: "The murderer is about 173 to 176 centimeters tall, of moderate build, aged between 25 and 30, and has a high level of education, but his mental health is not good. He is suspected to be young. There have been shadows such as the broken relationship between brothers. He likes to hide himself on weekdays, so he is used to wearing dark clothes. If necessary, he will wear a hat to hide himself."

The murderer is already a person who often appears in the ward. He likes to watch the pain of the dead. He knows how to make a financial management app, knows how to poison slowly, and can perfectly hide himself. The level of culture? The level is not too low, but he chose the job of a cleaner , His purpose of coming to the hospital is not simple.

The targets of his crime were the two brothers of the Guo family. He not only killed Guo Yue, but also defrauded Guo Teng of a large amount of insurance money, murdered and defrauded the two brothers.

Wen Wen said, attracted by the portrait on the table, pointed to the portrait curiously and said to Shi Han, "This? The painting is a bit like what we deduced!"

Shi Han stepped forward to check, suddenly remembered something, frowned and asked, "Where did this portrait come from?"

Li Qi explained it again, but now they couldn't find anyone who looked like the one in the painting. Poor Xiao Zhou was about to start doubting life.

Yan Ran woke up faintly when he heard the voice outside, and when he walked out of the forensic office, he saw the painting in Shi Han's hand at a glance. ?”

This is an old friend. If I don't think of him often, my memory will be blurred after such a long time.

The author has something to say: Li Qi: Yan Ran, your old friend... is that kind of old friend?Like Shi Han's rival in love?

Yan Ran: No, it's just the friends we played with when we were young.

Li Qi: Oh~ Then why Shi Han's eyes are so scary.

Yan Ran: Maybe... It's been a long time since I've seen someone unfamiliar!

Shihan: It's impossible to be unfamiliar, he deliberately proposed to play house, asking you to be his bride, I will remember it forever.
