Chapter 11 Is she the murderer?
Zhou Ning nodded, handed the fingerprint comparison report to Xu Dayuan, and then picked up the camera.
"This is the result of fingerprint comparison. The interior of the Volkswagen CC was carefully cleaned, and only traces of fingerprints from a glove were found. However, many fingerprints were found on the Nissan car, including the fingerprints and palm prints of the ex-boyfriend Wang Fuhao. This proves that what Wang Fuhao said about the car-changing competition was true.
As for the Volkswagen CC, we found signs of replacement of the windshield, bumper, headlights and tires, although the murderer erased these evidences.
However, the reaction of luminol reagent on the hood was positive, and the pattern was exactly the same as the bloodstains between the ribs of the deceased. Bloodstains were also found on the wiper cover. Zhao Xinli has sent it for testing and the results are estimated to be available in three hours.
Although the results have not come out yet, I am 90% sure that it was Yang Yufei who hit the deceased Su Manli while driving the Volkswagen CC. As for the murderer who stabbed Su Manli, this needs to be confirmed by Xu Dalai.
However, one thing is undeniable: in the early morning when visibility is poor, if the speed exceeds 150 miles per hour, and a person appears at the exit of the bridge, he may not be able to see clearly whether he hit a person or an animal.
Xu Dayuan threw down his hat, slapped Zhou Ning on the shoulder, and stared at Zhou Ning with bloodshot eyes.
"Xiao Zhou, forensic doctor, you are my lucky star. This evidence can beat them to death. No one can find out anything. This gives me the confidence to proceed with the trial. I will commend you for the credit when the case is over.
By the way, the girl named Wenxuan is on her way, you will need to help check her bag later."
Zhou Ning nodded. As long as the case could be solved, it would be fine. As for how to interrogate the suspect, that was not his concern. After all, the case was clear. However, he was still very interested in that girl. She was so ruthless and decisive. She was really extraordinary.
"Has the girl's identity been checked?"
Xu Dayuan smiled.
"You are quite gossipy, kid. Let me tell you, her name is Sun Wenxuan, she is also a student of the Medical School, and she is in the same class as Su Manli. Her father works for the Lihua Group.
As for the rest, we can guess most of it without even trying the case. The young people are jealous and want to get close to Yang Yufei. They think Su Manli is an eyesore. I don't know if the murder weapon can be found so easily."
Zhou Ning blinked and thought of the small hole in the purse.
"Let's talk about it later. A girl always wants to maintain her image in front of the person she likes."
At this moment, there was a sound of car doors slamming outside the window. Looking downstairs, I saw several people bringing Sun Wenxuan in. The girl kept crying and shouting softly:
"Why are you arresting me? What crime have I committed?"
Xu Dayuan grabbed the fingerprint comparison report, pointed at the door towards Zhou Ning, and then left.
Zhou Ning let out a long sigh and saw half a pack of Su cigarettes on Forensic Doctor Liu's desk. He took out a cigarette and lit it. He was not a heavy smoker and had just smoked for fun at first, but now he really needed a little mental relaxation.
The twenty-four hours have been truly thrilling. It can be said that they were more exciting than the previous twenty-six years he had lived.
The noise downstairs gradually faded away until the cigarette was finished and the office door opened again.
Xiao Liu leaned forward and waved at Zhou Ning.
"Xiao Zhou, forensic doctor, Xu Da asked me to ask you to come over and check the suspect's belongings."
Zhou Ning nodded, put on a mask, gloves and hat, carried the investigation box and camera, and followed Xiao Liu to the interrogation room on the first floor. This was his first time here and the door was locked with a combination lock.
When you open the door, the upholstered blue wall stickers and the iron chair are very eye-catching.
Sun Wenxuan sat on the chair, her chest heaving, the tear marks on her face still lingering, but she didn't say anything.
Xu Da just waved his hand. Zhou Ning walked to Xu Da's desk, where the leather bag was placed. You could tell from the brand that it was expensive.
"Checking her purse, we have confirmed that it is her personal item."
Zhou Ning knew that this sentence was meant for Sun Wenxuan, but Sun Wenxuan said it with a struggle.
"My bag is very expensive, please don't touch it!"
This sentence was powerless. Zhou Ning lifted the briefcase and looked at the small hole at the bottom. He took a photo of the outside first, then opened the briefcase and saw the black knitted lining inside. He illuminated it with a flashlight and discovered the damaged part inside.
This part was obviously hard, and it was obvious that it was the trace of blood. Zhou Ning took another photo, then poured out the contents. He held the bag up and down with both hands, and searched the bottom, where a long strip of mark appeared.
Zhou Ning paused, knowing from the shape of the bag that this was a murder weapon. He opened the purse again and tore open a zipper on the side of the bag. A flat-blade screwdriver with a green plastic handle appeared in front of him.
The screwdriver was relatively clean, but blood was visible in the gap between the handle and the metal rod.
I really don't know whether to praise Sun Wenxuan for being smart or stupid. It was right for her to take away the murder weapon and bring the police investigation to a standstill, but why didn't she deal with this thing earlier and keep it for the New Year?
Without any instructions, Xiao Liu came over holding a bag of evidence.
Zhou Ning was not in a hurry. He took a fingerprint from the screwdriver handle, which was a very clear thumb print. He took the fingerprint sample of Sun Wenxuan from Xu Da's desk, and there was no need to use a comparison system. The fingerprints were a perfect match, with not a single corner missing.
Then he threw the screwdriver inside, took a sample from the hole on the outside of the bag with a swab, and then cut a piece of knitted fabric from the corresponding part put everything away and then looked at Xu Dayuan.
"Mr. Xu has finished collecting samples. The fingerprints on the screwdriver are from Sun Wenxuan. However, the blood test is very fast and the results will be available in three hours. However, the length and width of the murder weapon match the wound marks that caused Su Manli's death."
Xu Dayuan nodded with an appreciation look on his face. For Sun Wenxuan, this sentence was the last straw that broke the camel's back. After all, all her hopes were shattered.
Yang Lihua has the ability to protect her son, but what is she?
It was too late to avoid suspicion, but at least the appearance of Sun Wenxuan saved her son from the charge of murder.
Zhou Ning came out carrying the things, exhaled, and looked at Liu Yong.
"Did you hear what Master Xu ordered? Will you take me to the county hospital?"
Liu Yong nodded.
"Let's go. I just got my driver's license and the team has a car."
The two happily got in the car and rushed all the way to the county hospital. Zhao Xinli was already waiting at the door. After all, Zhou Ning was not familiar with the procedures here and had already contacted him on the way.
Seeing Zhou Ning staggering out of the car, Zhao Xinli hurried over, held Zhou Ning's arm, and took the evidence box.
"What's going on?"
Xiao Liu looked embarrassed and scratched his head and said awkwardly.
"It's just... it's just that Xiao Dao Zhou is a little carsick, it's okay!"
Zhou Ning shook his head, patted his chest to ease the tension, and straightened up.
"Block him, this guy drives like a jerk. He drives fast and slow on the road like a rocking car. He speeds up more and more at intersections, swerving left and right. I'm a person who doesn't get dizzy even when riding on a boat in force 8 winds!"
Zhao Xinli grinned and kicked Xiao Liu.
"You are tired of living, little Zhou, the forensic doctor, is very valuable now. If you don't have the skills, go practice instead of embarrassing yourself. You wait here for me to deliver the samples."
Xiao Liu hurried over to support Zhou Ning, and Zhao Xinli ran and stumbled into the building on the east side of the county hospital.
Zhou Ning drank some water and patted Xiao Liu.
"It's ok, I've recovered. Liu Yong, you go back first. I'll wait for the results and then go back with Zhao Xinli."
Liu Yong didn't waste any time and drove away.
Zhou Ning bought some fruits and a box of milk at the supermarket in front of the county hospital.
Zhao Xinli also came out at this time. Seeing what he was doing in his hand, he naturally understood what he was going to do and glanced at his watch.
"The first batch of tests are coming out soon. The person testing it said that it's just a blood test and it's very fast. I'll go with you to see Forensic Doctor Liu."
The two went directly to the orthopedics department. Forensic Doctor Liu deliberately kept a stern face, but his wife's attitude was much better than last time. Zhou Ning was always very decent in terms of social skills.
Forensic Doctor Liu asked about the progress of the case. He didn't expect that they got the results so quickly. Although they still needed to wait for tests, the forensic work was basically finished. You know, this was a murder case, and he was very excited.
It was not until Zhao Xinli received a call with the test results that the two of them stood up to say goodbye. Forensic Doctor Liu's wife personally escorted Zhou Ning and the others out.
After getting the test results, the two quickly returned to the forensic office, where Xu Dayuan was sitting at his desk waiting.
On the way, Zhou Ning had already seen the results. The two bloodstains, screwdriver, briefcase and lining on the Volkswagen belonged to the deceased Su Manli. He handed the report to Xu Dayuan.
Zhou Ning asked curiously:
"Did Mr. Xu and Sun Wenxuan confess?"
Xu Dayuan nodded, sighed and blew out a smoke ring.
"Well, she admitted that she was the one who stabbed Su Manli."
Looking at Xu Dayuan's appearance, Zhao Xinli realized something was wrong.
"Boss, what's wrong? Isn't it good that the suspect confessed? We can close the case now!"
Xu Dayuan rolled his eyes.
"You know nothing. Although Sun Wenxuan admitted that she stabbed Su Manli, it was under the instructions of Yang Yufei. Yang Yufei thought that Su Manli had an affair with everyone, so he designed this car race."
Zhou Ning and Zhao Xinli looked at each other and stood there in a daze.
