Sanfu and Xu Shaowei were interrogating Wu Xiaoyu. The murderer who calmly killed four strangers who had no connection with her was also calmly facing Sanfu's interrogation.
"Sir, I'm just going to buy a house. It's not illegal to look at houses and buy houses, right?"
"I started saving money when I was young. I sold scraps in elementary school, did odd jobs on holidays in junior high school, and saved money on New Year's Day. I've been saving money for nearly ten years since I graduated. I live in the top cupboard where other people's bedding is kept, and I live frugally with my family... Sir, of course I have the money to buy the Grand Canal now. I dreamed of living in a house overlooking the sea since I was a child. What's suspicious about this? Can't the lower-class workers live the life they want through their own efforts? Don't look down on me..."
"Why do you say I can't stand the hardships I've suffered in the past? I could afford a house at the beginning of the year, but suddenly couldn't afford it at the end of the year after I saved enough money? ... Hey, would you kill someone for something like this? Don't make up such a ridiculous excuse to slander innocent people."
"Don't lie to others. I haven't killed anyone. How could the old man identify me? Sir, you can't say anything nonsense. No matter how stupid I am, I know that spreading rumors is illegal."
"Sir, when can I go home?"
...
Jiayi stared at the woman in the interrogation room who was so tight, turned her head and thought for a while, then looked up at the other party Zhenyue and said:
"Brother Yue, now we have to start with the murder weapon. There is no dagger that matches the characteristics of the murder weapon in the suspect's home, so the suspect must have abandoned it somewhere."
A dagger that long cannot be burned.
"I have mobilized the PTU and the police dog team to conduct a full-scale search along the three lines from the crime scene to the murderer's home, from the murderer's home to the company, and from the company to the crime scene, looking for a dagger that matches the characteristics of the murder weapon. All sewers, rivers, parks, etc." Fang Zhenyue responded immediately, and showed a proud expression because he thought of and arranged this matter in advance.
He looked at her with burning eyes, as if he was expecting something.
Jiayi really lived up to her expectations. After a slight pause, she immediately nodded and said, "Brother Yue is really reliable!"
Fang Zhenyue pursed his lips slightly, and his mood relaxed.
"Also... Brother Yue, can we also find Wu Xiaoyu's childhood playmates, close family members, and current friends to ask about her daily routine, places she often goes to, places that make her feel safe, and her favorite outdoor places to relax on weekends... and then find a way to dig out her itinerary in more detail." Jiayi expressed her thoughts. "OK
, I'll arrange for someone to conduct a thorough investigation and evidence collection of everything around her. You can also ask Sanfu and others to ask about her itinerary in the past few days." Fang Zhenyue nodded in response and turned around to make arrangements.
Jiayi suddenly said again: "Brother Yue."
Fang Zhenyue turned around and looked back.
"The murderer must have known that the male owner Liu Lisheng was not at home." Jiayi said without thinking.
Liang Shule, who had been standing by and had not spoken, looked at Jiayi, then looked at Fang Zhenyue, a little confused.
Fang Zhenyue paused for a moment before saying, "She must have checked Liu Lisheng."
"If she had checked, there must be traces." Jiayi nodded.
"I'll arrange for someone to check the sales manager and the property management to ask Wu Xiaoyu if she has tried to find out about her neighbors and the situation of her upper and lower floors in Unit A on the 12th floor." Fang Zhenyue's eyes were blank, and he responded to Jiayi's words immediately.
"She uses computers in her work, and now the Internet can query some corporate information. Can we apply to check all the search records of the computer she uses in Wu Xiaoyu's company?" Jiayi asked again.
"I will go to Wu Xiaoyu's company to seek their cooperation, and then find professionals from the technology team to conduct an inventory of the history of Wu Xiaoyu's computer." Fang Zhenyue broke down Jiayi's ideas into concrete actions that could be implemented, and took every idea Jiayi proposed seriously.
Liang Shule stood at the side, feeling like he was sitting on a boat driven by Fang Zhenyue and Yi Jiayi. Before he could react, the two of them had rowed the boat from the Atlantic Ocean to the Arctic Ocean.
The two sides of the strait were discussing non-stop, and the boat had already passed through thousands of mountains.
Liang Shule blinked his eyes, looking at Fang Zhenyue for a while, and then at Yi Jiayi for a while, wanting to learn their ideas, but found that he could not keep up with their ideas. I want to learn their ability to break down goals into executable solutions, but I keep doubting that I am jumping to the next page... It's too difficult.
"Thank you, Brother Yue! And..." Jiayi thought for a moment and said, "If we consider it from Wu Xiaoyu's perspective, she must have made a lot of preparations before planning the murder, otherwise it would be impossible for her to be so perfect and appear so calm... Then, the books Wu Xiaoyu has read recently, the topics of conversation..."
She paused for a moment, and Fang Zhenyue immediately interrupted:
"Don't worry, I will personally lead the forensic department to Wu Xiaoyu's house for a second investigation. I will try my best to imagine myself as Wu Xiaoyu, and imagine what I would do if I clearly wanted to kill someone in that building... All the clues around her will be ignored. I will do my best to lead the team to find all the clues that may be related to this case."
"Yes... yes!" Jiayi suddenly felt that her stuck thoughts were clear, and she looked up at Fang Zhenyue's eyes.
The two recognized each other for two seconds, and suddenly smiled in tacit understanding.
Like teammates who know each other best, they raised their right hands at the same time, shook hands like arm wrestling, and then divided into two teams, each to perform their own tasks.
After Fang Zhenyue left the public area of the interrogation room, Yi Jiayi stood outside the one-way window of Wu Xiaoyu's interrogation room for a while, and then took Liang Shule to the forensic department.
Jiushu had just received the midnight snack sent by Yi Jiadong, and distributed it to Liu Lisheng and other detectives who were working overtime together, so he came to Fang Zhenyue and Yi Jiayi with a few cups of coffee and snacks, but he was disappointed.
After distributing coffee and barbecued pork buns to Sanfu and Xu Shaowei, Jiushu walked out of the interrogation room, stood in the corridor with the food in his hand for a while, looked around but still couldn't see the two people, and finally returned to the B team office in disappointment.
Some people's footsteps are too fast, and it is not easy to catch up.
...
...
The night was thick, and Liu Lisheng was persuaded by Jiushu. He directly found a hotel near the police station to stay in. Walking by the window, he could still see the police station in the distance.
He didn't sleep all night, and he saw that the lights in the police station were on all night.
The morning dew was damp and cold. Jiayi, Sanfu and Liang Shule were replaced by others and went home drowsily to catch up on their sleep.
When Jiaru and Jiajun got up for school, Jiayi went home and fell on the bed drowsy as if she was asleep.
In a daze, she felt someone wiping her face and hands with a warm towel, which was warm and refreshing, and she smelled a faint fragrance in her nose, and finally fell asleep.
In her dream, she walked through Unit B on the 12th floor of Unit 6 of Weili Jinhui where the murder took place countless times.
Her body overlapped with Wu Xiaoyu's. She saw with Wu Xiaoyu's eyes, walked with Wu Xiaoyu's feet, and held the dagger tightly with Wu Xiaoyu's hands, stabbing fiercely...
The maid and the hostess were too surprised and did not resist at all, so they did not hurt the murderer even a little.
There was no dandruff belonging to the murderer in their nails, and they did not pull off even one or two hairs of the murderer.
Even though the baby's grandmother waved a spatula to attack the murderer, after seeing the blood-stained stroller and her daughter lying in a pool of blood and twitching, grief overwhelmed other emotions and she was easily subdued.
Everything happened too fast, and they did not understand what happened and why it happened until they died.
The last second was a peaceful time, with only trivial things in her mind such as "What to eat tonight?" and "My scalp is a little itchy, it's time to wash my hair." How could she have expected such a disaster?
Was all this expected by the murderer?
The victim, who had no power, was an easy target for murder.
In the dream, Jiayi seemed to be trapped in an endless loop, knocking on the door of Unit B over and over again, killing four people over and over again...
All the images kept repeating, and the strong desire to "find something" made her trapped in the nightmare and unable to escape.
Until, after killing the hostess for who knows how many times, she was entangled in the murderer's body, hesitating between the baby and the grandmother, and finally made up her mind to implement her blueprint, regardless of the old and the young, completely abandoning humanity, and strode towards the baby carriage.
After stabbing the first knife, perhaps she still felt a little reluctant, she turned her head and looked at the grandmother in the kitchen, and stabbed the second knife hard, as if she felt the resistance brought by the soft and young body to the murderer. After all,
her emotions were a little unstable, she quickly pulled back her arm and strode towards the kitchen.
During this process, she did not keep an eye on the baby and the stroller, and did not notice that in addition to the resistance of the dagger piercing the flesh, there was also the scraping of the sleeves on the edge of the canopy above the stroller
. Jiayi jumped up from the bed suddenly, her eyes wide open, and she threw off the quilt and jumped out of bed.
Because she fell asleep yesterday, she did not have time to take off her clothes, and now she was not allowed to put on clothes again. She rushed into the bathroom, brushed her teeth, wiped her face, and used her fingers to simply twitch her short hair twice, then she grabbed her coat and rushed out of the house. She
pedaled hard all the way to the police station, and her cheeks were red from the wind.
Without stopping, she ran to the Forensic Office.
The colleagues in the Forensic Department thought she was here to pick up the report of the second investigation yesterday, and hurriedly took a few reports that had been issued and brought them to her.
Jiayi took a quick look and saw that there was no trace element test on the stroller. She asked Diane again and learned that the stroller had been taken back to the police station a long time ago and the second inspection did not re-examine the stroller. Jiayi immediately grabbed Diane's hand and said anxiously:
"Sister Diane, can you re-inspect the stroller and collect trace elements again?"
She thought for a moment before saying:
"When the murderer swung the knife, the arm may have touched the stroller. In this area, all the sharp parts of the stroller, the metal joints at the corners, and all the hair, wool, etc. on the stroller that did not belong to the victim's family."
Diane was stunned. She still had a bunch of evidence collected by the second investigation that had not been tested yet... But seeing Yi Jiayi's wrinkled collar and her face that was as red as an apple blown by the wind, Diane sighed, nodded, and promised:
"I will go to collect trace elements and test the stroller immediately."
"Thank you, sister Diane!" Jiayi shook Diane's hand vigorously with both hands, and then walked to the corner of the forensic department where no one was sitting, obviously intending to wait here.
Diane was helpless, turned around and told Ajie to pour a glass of water for Yi Jiayi, then put down all the work at hand, went to the room where the evidence was placed, found the stroller, removed the vacuum bag, and not only re-inspected the stroller, but also wiped the inside of the large vacuum bag that contained the stroller.
More than an hour later, Diane walked out of the laboratory with another laboratory technician. When they walked to Jiayi's side, they saw that she had fallen asleep on the table.
Diane stopped Ajie who wanted to wake Jiayi up, and personally took Ajie to the B team office, and asked Fang Zhenyue to take them to see Wu Xiaoyu.
In the mattress room in the prison where Wu Xiaoyu was detained, the fluff that fell from Wu Xiaoyu's coat was collected.
Then they hurried back to the Forensic Department.
Seeing that Jiayi was still sleeping, thinking that Jiayi had stayed up all night last night and probably only slept for less than 3 hours this morning, Diane brought her coat over and put it on Jiayi, and told everyone in the office to keep their voices down, close the doors and windows to prevent ventilation, and not wake up Yi Shazhan, and then rushed in again.
After testing and observation under a microscope, Diane finally produced a powerful scientific report -
the plush hanging on a corner of the stroller's sunshade and the plush on the coat worn by the suspect Wu Xiaoyu had a 98% consistency in composition, as well as a 98% consistency in terms of newness and degree of fading due to sunlight. In addition, trace element tests revealed the same detergent ingredients and fragrance ingredients.
After getting the test report, Diane turned to look at Chen Guangyao, her face also filled with a sense of accomplishment, "Brother Da Guangming, fortunately at the beginning of the year we updated all the test equipment according to your needs despite the financial pressure.
"Thank you for sending me to the UK for special training, and taking me to join the trace element test limit test group of the University of Hong Kong after returning to Hong Kong... If it weren't for the improvement of our entire team's trace element testing capabilities..."
Diane took a deep breath, emotions surging in her chest.
"It should be, if it were you, you would do the same. "Chen Guangyao patted Diane's shoulder, and the two of them walked towards an unused desk in the corner of the public office area of the Forensic Science Department with the test reports in their hands.
Jiayi leaned over the table, and the coat draped over her fell slightly, revealing her eyelashes trembling in sleep and the blush on her cheeks.
The skilled policewoman was as defenseless as a baby while sleeping.
Diane turned her head and smiled at Brother Daguangming, then patted Jiayi's shoulder gently.
"Yi Shazhan..." Diane's voice was particularly gentle.
Jiayi muttered twice before she woke up with Diane's gentle shaking.
When she looked up, she saw the loving smiles of Brother Daguangming and Diane, and a sentence emerged in her mind in a trance:
"Mom and Dad, what's the matter that woke me up? "
Until Diane shook the four test reports in her hand at her and whispered, "The trace element test you asked me to do is done. We have caught the murderer, Yi Shazhan!"
"......!" Jiayi's eyes suddenly focused and she stood up abruptly.
