Qin Nan also rummaged through Zhou Zhi's closet, but found no other valuable clues, and then left the room.
Ma Xiaotao and Wu Haotian were chatting and laughing with the old lady. After seeing Qin Nan come out, Ma Xiaotao blinked and said that she had finished asking for relevant information. Qin Nan also made an OK gesture.
Immediately, the three of them left the old lady's house. After leaving the old lady fifty meters away, Ma Xiaotao glanced back to make sure that she had returned to the house and asked:
"Detective Qin, have you made any new discoveries?"
"Well, I found this." Qin Nan took out a notebook from his clothes and said.
After Ma Xiaotao took it, she saw the page with the paper between it. After reading the suicide note, she couldn't help but sigh, shook her head and said, "What a silly child..."
Ma Xiaotao handed the notebook to Wu Haotian, and Wu Haotian shook his head helplessly like her.
"I didn't expect that the bus bombing was committed by this kid who had just turned 20. He was so stupid that he committed suicide for revenge, and he also killed six other people on the bus. Alas."
Ma Xiaotao then sighed and said.
"Well, judging from the diary, Zhou Zhi shouldn't have planted the bomb in the sewer. I initially thought he was the one who handed the explosives to He Shizhu, but it doesn't seem to be the case. Moreover, Zhou Zhi's explosives were homemade.
However, we don’t know where his materials came from. This case probably happened by chance. The explosion that occurred outside the bus caused the shock wave to shake the vehicle.
Zhou Zhi seemed to have been frightened at that time and accidentally detonated the bomb on his body, causing a 'secondary' explosion."
Ma Xiaotao and Wu Haotian also nodded in agreement. Then they asked the neighbors who lived near Zhou Zhi. Some said Zhou Zhi was naughty, while others said he was very sensible.
Others expressed that they didn’t know much about it, and when visiting those who felt that Zhou Zhi was ignorant, they were more or less the ones who refused to return things after borrowing them, or were said to be stingy.
The things they borrowed were mostly firewood, rice, oil and salt, and some were steamed buns. However, none of these people asked the old lady, because everyone knew that the old lady's family was not well-off, and an old man had to take care of a grandson.
And my granddaughter also passed away due to an accident a few years ago.
It was already around five o'clock in the afternoon. As soon as Qin Nan and others got into the police car, Wu Fayi called, saying that there were further findings in the autopsy and indicating that they should return to the police station quickly.
Due to the heavy traffic on the road, the group arrived at the police station around 6:30.
Qin Nan and others went straight to the forensic room. At this time, Song Yi was also sitting on the iron chair outside the forensic room, frowning as if thinking about something.
After seeing Qin Nan and others coming over, he quickly stood up and asked, "Has the identity of that boy been found out?"
Qin Nan briefly explained the investigation to Song Yi. Song Yi couldn't help but sigh after listening. At this time, the door of the forensic room opened and Li Bing walked out wearing a mask.
"Are you here too? Team Song, the autopsy results are out. The victim is a female, with a bone age of about forty years old. You can go to the forensic room to discuss it in detail..." Li Bing opened the door and said.
Several people walked into the forensic room and saw an incomplete-looking corpse lying on the forensic bed. At this time, there was no blood on the corpse, and the hands and feet had been sewn together by Li Bing and Wu Fayi.
Wu Haotian couldn't help but frown after seeing it and felt a little nauseous. Qin Nan clenched his fists and covered his mouth to hold back the nauseous feeling.
After Wu Fayi saw Qin Nan and others coming in, he hurriedly stepped forward, picked up the stack of reports in his hand and said:
"The victim was a female, about 40 years old, and the time of death was from 21:00 on the evening of February 12 to 2:00 on the evening of February 13. We can only calculate this approximate time of death because the victim's body passed through the septic tank for a long time.
soaking of time,
In addition, after an explosion, we cannot repair the victim's face for the time being, and can only see it through the victim's skull. We have roughly restored the victim's face on the computer, please look here..."
Wu Fayi flipped through the report to the page with pictures, and saw only a colorful portrait of a face. The woman in the picture had a rather round face and looked very ordinary.
Qin Nan frowned, looked at Wu Fayi and asked, "Did you draw this?"
"Yeah, what's wrong?" Wu Fayi looked at Qin Nan with some confusion.
"Aren't you a forensic doctor? Why can you simulate portraits? You're so awesome." Qin Nan admired.
"I'm a forensic doctor, and I'm also a simulation portrait artist. In fact, I'm better at simulation portraits..." Wu Fayi smiled awkwardly.
No wonder Lao Li said he was a treasure. It turned out that he still meant it. I don’t know what impact Wu Fayi had on Lao Li and the others after he left Yunchang.
Song Yi looked at the simulated portrait, then at Wu Fayi, with an imperceptible smile on his lips. When Wu Fayi came to apply for the job, Song Yi was still a little hesitant when he saw that he was a forensic doctor.
Because there was already a chief medical examiner in the bureau, and Wu Fayi had just graduated, and he had only completed an internship in Yunchang for three or four months. Later, Song Yi asked Lao Li why Wu Fayi came to the municipal bureau.
Lao Li was a little surprised when he heard this, because Wu Fayi told him that he no longer wanted to do forensic medicine and wanted to study abroad, so he was asked to leave Yunchang.
Unexpectedly, Wu Fayi went to the city bureau and was assigned to Song Yi's group. This made Lao Li angry for a long time. Song Yi heard it on the phone and hung up immediately.
He decisively pulled Wu Fayi into his team. As expected, in addition to his comprehensive knowledge of forensic medicine, Wu Fayi was also a simulation portrait artist, and he had a clearer mind than Li Bing during the investigation of the case.
This "treasure" made Song Yi feel happy. Song Yi planned to thank Lao Li after a while. If it hadn't been for him, Song Yi might not have brought him into his group at all.
"Captain Song, we can't find the victim's information based on this portrait alone. There should be no matching photos found in the public security system." Ma Xiaotao scratched her head and said.
"With this portrait, can't we ask passers-by? There must be someone near the victim's neighborhood who knows her." Qin Nan looked at Ma Xiaotao and said.
Ma Xiaotao looked at Qin Nan and nodded with some vague understanding.
"Have you found any other useful information?" Song Yi asked.
"Well, the little finger of the victim's left foot is missing. It is an acquired condition. It should be that some of the finger bones were severed in the past. No other useful information has been found yet." Wu Fayi said.
"Well, these alone are enough, not bad, young man." Song Yi smiled and patted Wu Fayi's shoulder, and Wu Fayi lowered his head in embarrassment.
Song Yi looked at the time, and it was already around seven o'clock. He thought for a while and said, "Thank you, everyone, I'll work a little longer. First, we'll lock down the area where the victim was killed. We'll investigate the rest tomorrow morning."
Wu Fayi and Li Bing can get off work now, thank you both for your hard work."
Song Yi looked at Wu Fayi and Li Bing with a smile...
Song Yi, Qin Nan, Ma Xiaotao and Wu Haotian came to the small conference room and sorted out all the information recently investigated. According to the clues provided in Zhou Zhi's notebook,
One night six years ago, his sister did indeed fall into the sewer, and the taxi driver, judging from the surveillance, did seem to be the driver of the bus that has crashed now.
Song Yi called the police station near Xinglong Street in Yubei District. Not long after, a surveillance video file was transferred to Song Yi's computer.
Song Yi opened the computer file and played the surveillance footage near the manhole cover during those nights.
In the early hours of February 13th to February 14th, two figures, one tall and one short, came near the sewer manhole cover. It didn’t take a guess to know that they were the two brothers He Shizhu and Gao Ren.
I saw the two of them working around here for a long time before sticking the time bomb on the manhole cover of the sewer. During the whole process, neither of them turned on the flashlight, and the illumination from the nearby street lights was not very good.
It was normal that no bodies were found in the sewer.
Qin Nan adjusted the time to the night of February 14th. On that night, only a few people and a few cars passed by the road, and no one opened the manhole cover again until the explosion on February 15th...
