Qin Nan frowned and used the biological inspection lamp to shine in that direction.
At this time, he discovered that there was a less obvious white spot in that place. The white spot the size of a needle tip was the trace of blood.
Most people can't see it, but Qin Nan really looks at these aspects very carefully. Based on the trace experience he has learned,
This seems to be the location where Huang Rujuan's head was knocked.
Qin Nan crouched down and lowered his head in thought, reasoning about the incident. Judging from the depth of the wound at the time, it seemed that the blood did not occur at the moment of being knocked.
If the wound is large, blood will definitely spatter in some places.
He used a searchlight to look around the corner of the bed and found no blood stains, only a relatively strong smell of disinfectant.
Qin Nan used the biological inspection lamp to look at the legs and feet of the bed. At this time, he found an obvious fingerprint mark on the inside of the foot of the bed.
The corner of Qin Nan's mouth raised, and he immediately asked Li Bing, who was investigating outside, to come in with relevant equipment for fingerprint comparison.
During this period, Qin Nan also discovered that there was some blood reaction at the connection between the inner bottom of the bed legs and the ground. He spent a lot of effort to move the bed a little bit.
At this time, a small piece of dried blood was discovered.
Li Bing didn't know what kind of spray he sprayed on it, and then he used a cotton swab to pick up a little blood.
Qin Nan signaled to Li Bing to drive the police car back to the police station and hurry up to issue the inspection report.
Qin Nan and she both understood that if their guess was correct, then this was most likely Huang Rujuan's blood stains and fingerprints. They could know the result just by going back and comparing the system's DNA.
Qin Nan looked at other things in the room and found no other clues.
He and Ma Xiaotao met in the living room on the first floor. Ma Xiaotao said that he found nothing. The two of them looked at Guo Liang, who was in a daze at this time, wondering what he was thinking.
Lin Qiao was playing with her mobile phone on the side, with a smile on her face from time to time.
Just when Ma Xiaotao was about to call Song Yi to ask if he had found Zhu Ying's whereabouts, at this time, the sound of a key turning came from the door of the house.
After several people in the room heard the sound of unlocking, they all focused their attention here.
Qin Nan and Ma Xiaotao also looked puzzled, because there were only traces of two people's lives in this villa, how could anyone else have the key to this villa.
Qin Nan looked at Guo Liang, seeming to be thinking about something. At this moment, he quickly stood up and walked over, his face full of fear and surprise.
At this time, the door slowly opened, and a tall woman walked in, looking very beautiful.
"Sister, let's not talk anymore. I will ask you to make a short video together after a while, so hang up now~" The woman smiled and hung up the phone.
Qin Nan, Ma Xiaotao and Guo Liang suddenly opened their eyes, because this woman was none other than Zhu Ying they had been looking for!
Zhu Ying was slightly startled when she saw the three people standing in front of her. When she saw Ma Xiaotao wearing a police uniform, she immediately understood something and was about to turn around and run away.
Ma Xiaotao also moved extremely quickly. He rushed in front of Zhu Ying, grabbed her arm, turned around, took out the handcuffs from her waist and cuffed her tightly.
Zhu Ying's foot was sprained because she was wearing high heels, and she sat on the ground in pain.
Lin Qiao, who was browsing short videos over there, noticed the movement here and put down her phone. When she saw Zhu Ying coming, her eyes widened.
She looked at Guo Liang and then at Zhu Ying, her face full of confusion and anger.
"Didn't you say that you broke up with Zhu Ying a long time ago? What's going on? How come she has the key to your home?" Lin Qiao looked at Guo Liang and said angrily.
At this moment, Guo Liang slowly squatted down, scratched his head desperately, and said nothing.
At this time, Zhu Ying also noticed Lin Qiao here, and she shouted angrily:
"You bitch? Are you seducing Brother Liang again?! Let's see if I don't beat you to death!" Zhu Ying was about to get up but was stopped by Ma Xiaotao.
"Be honest! Come and talk to me inside!" Ma Xiaotao shouted.
Ma Xiaotao took the three of them to the sofa over there. In order to prevent Lin Qiao and Zhu Ying from fighting, he sandwiched Guo Liang between them.
Qin Nan also dialed Song Yi's phone number and said that two more police cars would be sent over.
At this time, Lin Qiao and Zhu Ying were staring at each other fiercely. Ma Xiaotao held his hands and frowned, walking back and forth in front of them. Seeing that the three of them were silent at this time, he asked:
"Zhu Ying, please tell me first what's going on and why you imitated Huang Rujuan's voice and called our police station."
"I..." Just when Zhu Ying was about to speak, Guo Liang touched Zhu Ying with his elbow. Ma Xiaotao saw all these small actions.
Ma Xiaotao patted the table and shouted: "Be honest! Zhu Ying, tell me what you know honestly. If you conceal it, you will go to jail!"
Upon hearing this, Zhu Ying's face changed drastically, tears popped out of the corners of her eyes without any warning and she cried:
"Police sister, it's none of my business. I didn't do anything. I really didn't do anything!"
Ma Xiaotao patted the table again and said, "Why did you imitate Huang Rujuan's voice and call us!"
Ma Xiaotao had no direct evidence that it was Zhu Ying who made the call. It was all their speculation. She just wanted to try to deceive her to see if she could tell her any useful information.
I saw Zhu Ying desperately trying to break free from the handcuffs on her back, and then cried and said:
"The police sister has nothing to do with me! It was the old guy Guo Liang who asked me to make all the calls. It was all him!
He asked me to go out for the past few days to avoid the limelight. I came back early just to see what was going on. He didn’t answer his phone calls or reply to his WeChat messages.
No, I didn’t expect…”
Zhu Ying was also crying at this time, and looked at Lin Qiao fiercely. Lin Qiao also looked at her fiercely at this time, as if the two of them were ready to fight at any time.
At this time, Guo Liang, who was sitting in the middle, was lowering his head, covering his head and not knowing what he was thinking.
Qin Nan also stepped forward and asked: "Zhu Ying, do you know the history of the case? If you tell everything you know, you will be dealt with lightly..."
Before Qin Nan finished speaking, Zhu Ying cried and said: "I said, I said, that night was actually like this..."
[Author's digression]: On the evening of November 27, Zhu Ying went home
