Even though she found the mobile phone, Jiayi didn't dare to touch it. After inserting a small flag to mark the location, she had to wait for colleagues from the Forensic Department to come and do an environmental survey before they could professionally remove the evidence.
Uncle Jiu collected the rope, and Jiayi climbed up by pulling the rope.
After returning to the road, she took off her gloves, and her palms were indeed rubbed red, and the insides of several fingers had red rashes like bruises. There were small bloody marks on her wrists and neck from being scratched by the thorns of the bushes at some point. When she pulled up her trouser legs, she saw blood spots from the thorns that penetrated her trouser legs. You really
can't just walk through the wild bushes casually, all plants are assassins.
She walked up to Uncle Jiu and opened her palms to him.
Uncle Jiu also took off his gloves and showed her his palms.
Both palms were covered with red rashes and abrasions. The two people who didn't personally run rough missions had become too tender.
Jiayi looked up and stuck out her tongue at Uncle Jiu, who raised his eyebrows. After exchanging glances, the two teammates who had shown off their "medals" smiled at each other.
The PTU police officers nearby also climbed onto the road one after another. Only one police officer found an area of ​​bloodstains, and the others didn't find anything.
PTU Sergeant Nie Chen, who had been "worried" about Jiayi's safety just now, walked to the other side on a rope. This time it was his turn to go down the hillside. When passing by Jiayi, he couldn't help but stop and raise his eyebrows:
"You are indeed a lucky sharpshooter. No one else found the clues, but you did."
Jiayi was facing her palms towards the mountain breeze, letting the cool breeze blow on her palms to reduce the burning pain of the friction injury.
When she heard Nie Chen's words, she didn't realize that he was teasing her at first, and instinctively thought that they were just chatting. It wasn't until Nie Chen took two steps away that she realized that there was some contempt in his tone.
Turning her head and staring at Nie Chen's back, she saw that he was about to go downhill, so she chased him for two steps and argued:
"Sir Nie, it wasn't luck that I found the mobile phone."
Nie Chen turned around in surprise, "What?"
"I analyzed the victim's movement based on the footprints left at the location where the first piece of evidence was found, and then drew an extension line based on the direction of the footprints and the movement analysis. These are all conclusions drawn based on logical analysis. If something was thrown out or dropped during the dispute, it is most likely to appear on this line.
"Because I focused on the area near this line, I found this mobile phone. "
Jia Yi was standing on the side of the road with a hemp rope tied around her waist. When she looked over, her expression was serious and her eyes were solemn.
Nie Chen blinked. The female police officer seemed like a student who was angry and argued because she was wronged during her school days. The kind of student who was not particularly flamboyant and stupid in the past, but will make you sigh when she stands out.
"Which extension line are you talking about? "Nie Chen scratched his head, turned to the cliff slope and looked down.
"..." Jiayi's emotions disappeared in an instant. She was dazed for a moment before she walked to Nie Chen's side and pointed out the place where the blood-stained suit was found. The colleagues from the forensic department were collecting evidence there.
After Nie Chen nodded, Jiayi pointed a little to the left and introduced: "There are many footprints there. The suit should have been killed when the victim was standing there arguing. Although you can't see the footprints and other details over there clearly standing here, you can see that there is a gap in the bushes there, right? "
Nie Chen nodded again, indicating that he saw it.
Seeing that he was really willing to learn from him humbly, Jiayi no longer looked down on him and teased him like before, so she stretched out her finger to draw a line, pointing and saying:
"Imagine the movements of two people arguing. People's joints and movements determine that when throwing things, they will instinctively throw forward or backward. Although the possibility of throwing things to the left or right during the tearing process cannot be ruled out, things can be thrown very far forward, while things thrown backward, left or right, or things that are knocked off, can be thrown a shorter distance.
"So when we search, we should focus on the area in front of the suspect, where we can search a little further, but we don't need to search so far in other directions.
"Other areas are not impossible. After all, there are all kinds of emergencies in the real world. For example, the crime scene is at the bottom of a slope, so if we throw something at the bottom of the slope, no matter which direction the victim is facing, it can be thrown far away.
"But we can still plan the most effective search area according to the current situation."
Nie Chen listened and nodded, then squatted down, picked up a stone, scraped a circle on the cement road, and drew a long line in front of the victim. Then he looked up and asked:
"The most effective search area you mentioned is this, right?"
Jiayi also squatted down, took a look, and nodded in approval.
Nie Chen patted Jiayi on the shoulder, stood up and clapped his hands to attract the attention of all the PTU sergeants and police officers, then used his fingers to draw out the most effective search area for everyone, reminding everyone to search this area especially carefully.
The police officers said they got it, and Nie Chen cleared his throat and put down his arms.
He turned his head and saw Jiayi concentrating on watching him redo the search plan, and smiled: "Officer Yi Jiayi, you are quite capable, you speak very well, you CID is worthy of being a criminal investigation, you are very strong in logic, quite amazing."
He nodded, tugged at the hemp rope around his waist, and after ensuring safety, he prepared to go downhill. Just after taking a step forward, he suddenly remembered something, looked up at Yi Jiayi who was about to leave for work, and said, "Oh." Jiayi
turned her head, and Nie Chen raised his left hand that was pulling the hemp rope, extended his index finger, and smiled indifferently: "I was a little disrespectful just now, I apologize, sorry."
"..." Jiayi stood there, the other party bowed his head so happily, it seemed that she was making a fuss and being petty just now, and she curled her lips shyly. She felt a little happy because of being recognized, and her smile grew unconsciously. Her straightforward personality finally prevailed. She smiled with her teeth showing, waved her hand and said:
"Be careful, Sir Nie."
Nie Chen nodded slightly, and held the hemp rope with both hands. As soon as his hands loosened, he slid down the cliff and got into the bushes.
When Jiayi returned to Uncle Jiu, Uncle Jiu re-wrapped the hemp rope and asked with a smile:
"Teach them some principles of life?"
Jiayi chuckled, nodded and raised his eyebrows: "Let them know the professionalism of CID agents."
"Haha."
The PTU police officers expanded outward like a rolling stone to conduct a map-style search, which was very fast and efficient.
Colleagues from the forensic department collected and took photos of the suit and the footprints and other details around its location, and then were pulled onto the road by Fang Zhenyue and Sanfu.
After everyone sorted out the clues, marked them and put them in the boxes, they walked to the area where Jiayi climbed up. Under Jiayi's guidance, they climbed down to the vicinity of the Big Brother building to find a place where they could stand firm and collect new evidence and clues.
Jiayi walked around the road again, carefully observing the spot where the bloodstained suit was found, then walked to the spot where the mobile phone was found, and then took the spare flashlight brought by the PTU and turned back to illuminate the curved road section in this area.
She lowered her head and looked at the ground on the road, looking left and right, and when she looked at the edge of the road, she would bend down to take a closer look.
Fang Zhenyue tightened the hemp rope that tied the chemist, and looked back at Jiayi from time to time to make sure she was within his sight.
After seeing her suddenly squatting down in a place, he asked:
"What did you find?"
The wind carried his voice to Jiayi's ears a few meters away, which seemed a bit distant and even deeper.
Jiayi turned around and said, "Brother Yue, there is a cigarette butt here, but we are not sure if it was thrown here today. If we can confirm that the time when the cigarette butt was thrown away is consistent with the time when the blood-stained suit and the mobile phone appeared, it may be thrown away by the victim or the suspect, and it may be possible to collect saliva and other information."
Awei, a junior chemist guarding the road, heard Jiayi's words and immediately looked over.
"Please collect the evidence." Fang Zhenyue said.
"Yes, sir." Awei nodded and immediately walked over with the evidence bag to collect the cigarette butt that Jiayi found.
"Awei, do you think this looks like a wheel accident caused by braking?" Jiayi remembered that when Brother Yue's jeep drove over, it slowed down slowly and stopped, and did not brake suddenly.
The cement scratch marks left here were not covered by the soil, nor were they cleaned up by the road maintenance workers and cleaning workers. They looked like they were newly left.
"Let me take a picture." Ah Wei hurried back to get the camera.
Jiayi took pictures of the road surface, and Ah Wei took pictures.
"Can you tell the model of this car by the wheel tracks?" Jiayi suddenly raised her head and asked.
"..." Ah Wei looked confused, huh? "No."
"Oh." Jiayi lowered her eyes, looking very disappointed.
"But... I'll ask Sister Teresa, maybe she can tell whether it's a large, medium or small car based on the wheel tracks." Ah Wei carefully looked at the brake marks, which should be able to roughly judge the distance between the front and rear wheels, as well as the width of the wheelbase.
"That's great. Let's not mess around here. You can put up two warning barriers outside this area." Jiayi suggested.
"Yeah... OK." Ah Wei almost shouted "yes, madam" subconsciously, but when he realized that the person standing in front of him was not his superior, he quickly changed his words.
He turned back and found four red warning barriers and a digital marker of the clue extraction point from the things he brought with him, and placed them around the area where the wheel tracks were left, so as to remind the police officers collecting evidence at the scene not to contaminate or destroy the clues here.
"It is certain that the victim was in the car going down the mountain. The victim and the perpetrator were in the same car. Who was the driver?" Jiayi raised her flashlight and shone it towards the mountain. There were many wealthy villas on the way up the mountain. The nearest one was the Yishan Villa Community. There were other villa communities such as the Shixundao Villa Community above. It was difficult to determine where the car came from based on the current clues.
After all, at least you can't infer the starting point by looking at the wheel, unless you collect some fiber or some substance from the wheel that is only found in a certain villa community.
The laboratory technician Ah Wei nodded his head, trying to adjust his logic to follow Yi Jiayi's question: "If there are footprints, maybe we can match them."
"Yes!" Jiayi immediately gave a definite answer. When Ah Wei pursed his lips and smiled, she held up the microphone and bent over to look for it beside the wheel of the car that braked suddenly.
Ah Wei also bent over to look for it. It is difficult to leave identifiable footprints on the cement ground. Even if special means are used to collect them, in the end, only a bunch of bumpy marks on the surface of the earth can be collected.
But on the soil, it is possible. The two of them walked along the wheel to the edge of the road, crossed the roadside guardrail, and looked for traces on the soil.
Sure enough, there were two pairs of footprints that sometimes overlapped, extending all the way to the area where the suit was found.
"Take pictures quickly, take pictures of the footprints and the broken parts of the trees next to them." Jiayi said hurriedly, holding up a flashlight to help illuminate.
"OK." Ah Wei immediately did it.
"Logically, the footprints in front should be from the victim, and the footprints in the back should be from the perpetrator." Jiayi led Ah Wei along the way, taking pictures all the way.
"Yes, unless there is other evidence pointing to another conclusion later, it is what you said." Ah Wei nodded.
"Yes, take pictures of them all, and then add all the footprints, all the clue reports and test reports to do case analysis together." Jiayi pointed to the tree branches again: "Take pictures here too. Hey? Is there a piece of meat hanging on the broken tree trunk?"
"It seems so." Ah Wei raised the camera and took pictures.
"Please help me collect some evidence, Brother Wei." Jiayi said with a sweet smile.
"No problem, Sister Jiayi." But Wei didn't dare to accept Jiayi's polite address, and called her "sister" instead.
Jiayi couldn't help laughing, thinking of Brother Yue and Uncle Jiu, you call me "brother" and I call you "uncle", and the hierarchy is messed up.
Wei returned to the car they drove when they came, took the evidence bag and came to collect evidence.
Far away, Fang Zhenyue watched Jiayi and Awei investigating and collecting evidence along the corner, and couldn't help but say to Sanfu:
"It's only been a few minutes, and Eleven has already become familiar with the police officers of the Noon Police Station and the PTU, and now she even has a personal follower."
"Haha, Sister Eleven has some charisma." Sanfu was still pulling the hemp rope in his hand, while he was pulling or releasing it according to the requirements of the laboratory technician below, and turned his head to look at Yi Jiayi and Awei.
Then he saw Awei nodding and cooperating from time to time under Jiayi's instructions, and occasionally he would turn back and discuss with Jiayi, showing a tacit cooperation and harmonious appearance.
On the other side, the PTU police officers were conducting key searches according to the areas pointed out by Jiayi. After PTU Sergeant Nie Chen finished screening a series of areas, he returned to the road and continued to walk away. When he passed Jiayi, he would nod and greet her. The eleventh sister of society, smiling ,
arranged the dozens of people in this area clearly .
