Wu Kang understood and took out another piece of paper from his bag.
"We found traces of pheromone in your study," Li Ze said.”
Hearing this, Zheng Ziying's forehead began to sweat.
"Chromafrost is a colorless and transparent liquid. It is volatile and very sensitive to light.”
"Unfortunately, the curtains in your study have never been opened since the incident.”
"Therefore, no matter how meticulously you clean, you won't be able to completely remove the residue and decomposition.”
"This is the trace examination and identification report."
"Just a reminder, an authoritative appraisal can be used as evidence.”
Zheng Ziying did not speak.
She could no longer give a reasonable explanation.
Li Ze glanced at her and said,"There's another very important question."”
" July 1st, 9 AM."
"Eleven in the morning."
"Two in the afternoon."
"Eight o'clock in the evening."
"Where were you during these four times?”
The problem mentioned before was the alibi.
For four consecutive murders, Zheng Ziying definitely couldn't give a perfect alibi.
The difficulty was simply too great.
"Zheng Ziying, please answer my question.”
Li Ze's voice was cold.
"At home," Zheng Ziying said after a moment of silence.”
"Who can prove it?" Li Ze asked.
"I'm usually alone. No one can prove it." Zheng Ziying shook her head.”
"No one can prove that you were at home, but…" Li Ze smiled.
"But someone can prove that you're not at home.”
" What?!"
Zheng Ziying suddenly raised her head and stared blankly at the young man with a smile on his face.
"Your residence is Unit 101, Building 6," Li Ze continued.”
"This location is right next to the east gate of the residential area. It's the only way for all the owners to enter and exit.”
"Everyone who passes by can see the lights in your house.”
"We've visited. On the night of July 1st, the lights in your house were only turned on after ten o'clock.”
"So what?" Zheng Ziying frowned. I just went to bed early and woke up to eat something.”
"What a coincidence?"
"Yes!"
Seeing that Zheng Ziying didn't give up, Li Ze sighed,""But the surveillance cameras can't be faked…"
"No matter how careful you are, you can only guarantee that you won't be photographed at the crime scene, but you can't completely avoid all the surveillance cameras.”
Zheng Ziying was speechless.
" Do you really think that you'll be fine without fingerprints, footprints, DNA, and surveillance cameras?" Li Ze asked.”
"Criminal investigation is much more complicated than you think.”
Zheng Ziying remained silent.
"There are also hospital surveillance cameras."”
"To be honest, I didn't check."
"However, it's not easy to completely avoid the hospital's cameras. It's almost impossible, let alone killing a person.”
"I'm guessing you've done two things.”
" First, he went to the hospital's surveillance room and remembered the location of every camera in detail. As for the reason…"
"What do you think of the reason that the surveillance cameras were stolen?”
" Second, pretend to be a patient."
"You're wearing a hospital gown and a mask, and you've changed your hairstyle. You might not even be recognized face to face.”
"Which method did you use? Or did you use them all?"
On the other side, Wu Kang turned to look at Li Ze.
He had checked the hospital's surveillance cameras, but he did not find any suspicious people.
Did Zheng Ziying use this method to avoid the surveillance?
"Of course, this is just a guess."”
"Why don't you tell me?"
"Or should I take your photo and ask the security guard in the hospital's surveillance room?”
Zheng Ziying's eyes flashed with shock.
She was indeed a very smart person, but it depended on which aspect.
Crime was not her specialty.
He only knew the surface of anti-reconnaissance techniques.
She was too naive.
Wu Kang kept all the information.
At this point, Zheng Ziying's words were full of loopholes and contradictions.
A single piece of evidence might not be enough to convict the other party, but what they had was a complete chain of evidence of the entire murder process.
Under such circumstances, Zheng Ziying could not argue or justify herself.
Li Ze looked at the silent Zheng Ziying and said,""Do you still want to struggle?"
"It's not easy to strangle someone with your strength. You need time.”
"Pulling on the rope for a long time will definitely cause some damage to your palm and cause friction marks.”
"Even if you wear gloves, you won't be able to protect yourself completely.”
"Not to mention, you killed four people in a short period of time.”
"The mark on your palm…is it still there?”
These words made Zheng Ziying's body tremble, completely breaking all her psychological defenses.
After a long silence, she slowly opened her palm.
There were two dark red bruises on his palms. It was shocking and extremely eye-catching.
Li Ze stood up and waved at Wu Kang.
Wu Kang nodded and took out his handcuffs.
Kacha!
The handcuffs were stuck on Zheng Ziying's wrist.
"Zheng Ziying, you are suspected of murdering Li Xinrui.| Peng Qiang, Li Jiayun, Kong Lan."
" Cruel means, obvious motive."
"You're under arrest."
Zheng Ziying closed her eyes in pain.
Li Ze walked over slowly and looked at Fu Xiaojun.""Xiaojun, cover yourself with a piece of clothing.”
"I want to save Teacher Zheng some face.”
"Alright." Fu Xiaojun nodded.
Li Ze turned around.
"Take him away."
