Chapter 60 The murder weapon
Zhou Ning came over, and after Shen Guanlin saw the three of them clearly, he looked angry.
"It's you. What's wrong with the police? You can control citizens at will? What did I do wrong that you control my freedom like this? Give me an explanation?"
Zhou Ning stepped forward and tore off the isolation suit covering his chest. Three scratches and scabs were visible on the right side of his neck. If you look closely, you can see that there are scabs that have fallen off next to them. In a few days, these marks will probably disappear.
Zhou Ning felt relieved and looked at Shen Guanlin.
"It's meaningless to resist now. We are lucky to have found a male DNA in the victim's wound. If it is successfully matched with your DNA, it will be irrefutable evidence."
Shen Guanlin was stunned and stopped struggling. Xu Dayuan handcuffed Shen Guanlin.
"Okay, think about it on the way. It will be good for you to confess early. In addition, I can tell you that your son has been taken to the criminal police team."
Shen Guanlin looked at Xu Dayuan with a sharp gaze, but there was panic on his face.
"My son has nothing to do with this matter. Don't use this to threaten me. I have no problem . Just let him go."
Da Zhao chuckled and moved his fat face closer.
He came forward very considerately and put a white coat on Shen Guanlin's hand to cover the silver bracelet.
"Okay, stop talking about this. How to judge is our job as police officers. If it weren't for not wanting to embarrass the Eighth Hospital, do you think we would be talking nonsense with you here?"
Shen Guanlin didn't say anything else. Xu Dayuan pulled his arm and directly signaled the head nurse of the operating room to open the door. Shen Guanlin stared at the head nurse, and Da Zhao poked him.
"Don't look at people like that. Don't worry, I can't guarantee anything else, but you can't come back from here."
The head nurse of the operating room shook her head and looked at Shen Guanlin.
"It's okay, I'm not afraid. Just explain yourself Director Shen. It's good that you're gone. You won't cause any more trouble for the nurses in the operating room. It's a good thing to be in jail. At least you're alive and well. Reform yourself."
When Zhou Ning heard this, she looked at the head nurse of the operating room. It was obvious that they all knew some things about Shen Guanlin, but due to their status, they couldn't say many things. Besides, it was useless to say them, after all, many young people have different pursuits.
Xu Dayuan pushed Shen Guanlin.
"Let's go back to the team and tell them. If you don't mind being embarrassed, just shout."
The door opened and several people walked out. Many people cast their eyes at him. Shen Guanlin didn't dare to say anything and walked quickly towards the outside of the Eighth Hospital. When he met someone he knew, he tried his best to lower his head. Going out in his scrubs was too eye-catching in such a cold winter.
…
As soon as he arrived at the criminal police team.
Another police car also stopped, and He Chunyang jumped out of it, unable to hide the smile on his face. He was holding an evidence bag in his hand, which contained a plastic package. From the way it was entangled, it was obvious that it was a wrench.
Zhou Ning's eyes lit up and he hurried over.
"Have you found the murder weapon?"
He Chunyang grinned, very satisfied with Zhou Ning's response.
"Not only have we found it, but the guy who threw the murder weapon away was also an idiot. It was wrapped in several layers of plastic bags, the kind used by hospitals to store medical waste. They are really waterproof. Doctor Zhou, I'll leave this to you. I saw blood on it."
Zhou Ning took it, and Xu Dayuan also dragged Shen Guanlin out of the car. Several policemen rushed up and grabbed Shen Guanlin. He seemed surprised that the police could find the murder weapon and stared at the bag in Zhou Ning's hand.
Xu Dayuan patted Shen Guanlin on the shoulder, with a very comfortable expression on his face.
"Alright, stop looking. We'll know the result soon. Take him to the interrogation room and interrogate him separately from Shen Weijie. Doctor Zhou, hurry up. The test result will come out soon, right?"
Zhou Ning nodded vigorously.
"The Eighth Hospital can do it. I'll give you the results in two hours."
Hearing this, Xu Dayuan waved his hand, and several policemen pushed Shen Guanlin inside. Shen Guanlin seemed shocked by what he heard. He staggered and his Crocs almost fell off. However, the police beside him directly lifted him up, and their figures disappeared at the entrance of the first floor.
"Old He, is it ok? Is the location where the murder weapon was found far from where the body was found?"
"It's about a hundred meters to the south, also on the east bank, about twenty meters from the shore. I guess he couldn't see clearly at night and wanted to throw it far away, but it went off the track. We finally found it after three hours of searching."
Zhou Ning frowned slightly. If they could dispose of the body, they wouldn't be so hasty. Zhou Ning waved his left and right hands respectively, and his doubts became even greater.
"What did you think of, Xiao Zhou, the forensic doctor?"
"There are traces of fluorescent paint on the right shoulder of the deceased. Based on the shape, I think it was the right foot. Although the blow was done with both hands, the injury is located to the left of the occipital region. Combined with the stomping habit, it is an action that the left-handed person is more adept at.
According to what you said, the murder weapon was thrown to the south of the body dumping location, close to the shore. This is a characteristic of right-handed people throwing objects, just like when we throw things forward with both hands, the left hand tends to deviate to the right, and the right hand tends to deviate to the left. "
Xu Dayuan understood, thought for a moment and looked up and said:
"You mean, the murderer and the body dumper were two different people? Then let's try these two father and son to see whether they are left-handed or right-handed."
"Well, at least the person who threw the murder weapon was not the same person who hit the victim in the head."
Xu Dayuan kicked Da Zhao, who looked confused.
"What did I do? Why are you hitting me?"
He Chunyang couldn't help laughing, and his face looked a lot more relaxed as he moved closer.
"Xu Da really hates you for not living up to your expectations. So, you should work hard to learn the traces like this."
Da Zhao didn't dare to retort. Xu Dayuan had already taken He Chunyang and others to the interrogation room. Zhou Ning coughed.
"Okay, stop being depressed, hurry up and move your things upstairs. I need to collect blood for testing and search for fingerprints for comparison. There's a lot to do. Do you want to stay here and sigh?"
Big Zhao grinned and went to get the things from the trunk. A lot of things were found in Shen Weijie's car when he checked it before. Zhou Ning returned to the office with the evidence bag.
Throwing the clothes aside, he quickly put on gloves, carefully opened the evidence bag, and poured the contents onto the stainless steel table. In an instant, water flowed everywhere.
Da Zhao had followed in, put down his things, put on gloves and came closer.
“Does this water need to be sampled?”
Zhou Ning shook his head. The most important thing now was to find the bloodstains and fingerprints. The water was the same as the one sampled from the reservoir, so there was no need to keep it.
"Help me dry it with paper, then go get a hair dryer, don't turn it on too high, and dry the plastic bag I cut open, then check if there are any fingerprints on it. Oh, and call Xiao Liu and ask him if Shen Weijie's fingerprints have been delivered yet?"
Da Zhao looked bitter. Zhou Ning had assigned him too much work in one breath. However, he smacked his lips and did not dare to resist. He wiped the water and dialed the phone. Holding the phone, he talked to Xiao Liu while plugging in the hair dryer.
The knife in Zhou Ning's hand had already cut through the outer layer of plastic sheeting. His excited heartbeat quickened. As he peeled it open with his hands, the wrench was exposed, and the blood on it had dried.
Carefully taking out the wrench, Zhou Ning wiped the blood stains on the wrench with a wet cotton swab, taking out three cotton swabs at a time, and then dipped the swabs in powder and swept them across the front and back of the middle handle of the wrench. As he cleaned, several fingerprints were revealed.
Zhou Ning extracted the fingerprints with electrostatic paper and quickly entered them into the system before looking at Da Zhao.
"Are you done there?"
"Don't worry, it's already dried. There are teeth marks on this tape. We won't be so lucky, will we?"
"Cut it out and keep a sample. Look for fingerprints first. Are there any fingerprints on the tape?"
Da Zhao grinned.
"There are several of them. Come on, let me cut them out for you. This one is so clear."
Zhou Ning leaned over to take a look, and sure enough, there were fingerprints on it.
"Xiao Liu hasn't come yet?"
Just as he finished speaking, the door of the forensic office was pushed open, and Xiao Liu ran in, sweating all over, and handed two fingerprint collection cards and two tubes of blood to Zhou Ning with both hands.
"Mr. Zhou, these are the fingerprints and blood samples of Shen Weijie and Shen Guanlin."
Zhou Ning picked up the acquisition card, walked to the computer to enter the number, and then started the comparison. The fingerprint on the computer kept flashing, and after a while there was a beeping sound, the comparison stopped, and a bunch of comparison results appeared.
Comparing with the settings entered previously, Zhou Ning recorded in the notebook that he found four fingerprints of Shen Guanlin on the wrench, three fingerprints of Shen Weijie, and two unknown fingerprints. All three fingerprints on the outer wrapping tape were Shen Weijie's.
Four fingerprints of Shen Weijie were found on the tape wrapped around the license plate.
Zhou Ning heaved a long sigh of relief. Now he was just waiting for news from Xu Dayuan. By determining who was left-handed, he could determine who had beaten the deceased.
"Hurry up and send the blood sample to the laboratory of the Eighth Hospital. Send the two tape samples and three blood samples to the Municipal Bureau Testing Center for comparison with the DNA of the unknown male."
Da Zhao scratched his head.
"Wait a minute, I'm a little confused now, who is the murderer?"
