In the evening, Xu Lin was sitting at the table in the temporary office of the Criminal Investigation Detachment, looking at a case analysis form drawn in his hand.
The first person who died committed suicide by burning charcoal. An autopsy determined that he died of carbon monoxide poisoning.
The second deceased committed suicide by cutting his wrists. An autopsy determined that he died of excessive bleeding, and there was also surveillance video from the deceased's home as evidence.
In the surveillance footage, it was indeed the deceased who cut his own wrist. Xu Lin checked this point over and over again more than ten times, and there was indeed no problem.
The third deceased died by hanging, and the autopsy also confirmed that he hanged himself. Judging from the surveillance footage at the deceased's home, there was indeed nothing wrong with it.
The case seemed to have reached a dead end. Xu Lin thought for a long time but had no idea what the problem was.
After frowning and thinking for a moment, Xu Lin picked up the almost soaked instant noodles on the side and prepared to take a bite first.
But at this moment, the door was pushed open and Zhang Gong walked into the office.
"Deputy Team Leader Xu, I investigated the entire Jiangyun City No. 1 Middle School. During the entire last year, apart from the three children of the deceased, there was only one female student in the same grade who died of illness." Zhang Gong said.
"Died of illness?" Xu Lin raised his head, with a look of surprise on his face.
Zhang Gong: "Yes, he died of illness. The female student had congenital heart disease. We obtained her past medical records from the hospital, and it was indeed true. Her death time was March 19, and I have brought back the rescue records. .”
"And I also found the doctor specifically. The doctor said that he was also the attending doctor at that time. At that time, he also believed that the girl might not live to be 20 years old. It was just a little earlier than he expected."
After speaking, Zhang Gong placed a photo in front of Xu Lin.
The girl in the photo is pretty and sweet, standing in a sea of flowers, looking innocent and innocent, like an elf dancing in the sea of flowers.
"Jiang Yueyue?" Xu Lin read the girl's name, and then sighed: "God is blind!"
Then he raised his head: "Check the girl's family situation. It's best to talk to her parents."
Zhang Gong: "..."
He stood there, silent for a while, and then said, "Deputy Team Leader Xu, isn't this a little too cruel? After all, they just lost their daughter a year ago."
When Xu Lin heard this, the hand holding the instant noodles paused slightly.
yes!
It's really cruel to do this.
But in order to solve the case, he had no choice.
His intuition told him that there might be a connection.
What a coincidence. The girl died on March 19, and the three of them started to transfer schools in April.
The earliest transfer record was on April 3.
He said to Zhang Gong: "Team Zhang, you go and investigate the information about this female student's parents first, and then we will decide based on the situation."
Zhang Gong took out two files from his bag and said, "I have checked and found that the girl's parents both work in a communications operation company. One is a senior executive in the communications department, and the other is a network engineer."
Xu Lin nodded and took the files of the two people from Zhang Gong.
He took a look and saw that both of them were top students, graduated from prestigious schools, and had very good careers.
"Okay, put the information here, I'll take a look first."
"Okay!" Zhang Gong nodded, turned and left.
After Zhang Gong left, Xu Lin put the information on the table while eating instant noodles. Looking at the photos, his eyes suddenly froze.
An idea flashed in my mind, and I seemed to have missed something.
He put down the instant noodles, tore off the photos of the deceased girl and her parents, quickly came to the whiteboard behind him, and wiped off the case analysis on it with his sleeve.
Then I put the photos up one by one with small magnets, and then put the photos of the deceased and the photos of the deceased’s family members on them.
Then... they wrote down their respective occupations, possible connections, etc. under the photos.
Snapped!
Suddenly, he clapped his hands fiercely and stared at the deceased girl's parents, or rather at their careers.
Wen Qi, director of the operations department of a mobile communications company.
Jiang Zhenbin, deputy chief engineer of network communications of China Mobile Communications Company.
He turned around and ran back to his desk, looking for the information on the table, and soon found several documents from the messy pile of information.
The small shop across the road from deceased No. 1's house was monitored by a mobile communications company.
The houses of Deceased No. 2 and Deceased No. 3 had installed surveillance cameras through door-to-door sales in the past six months, and they were all products of mobile communication companies.
The three deceased people all used mobile numbers.
If all coincidences are connected together, then they are no longer coincidences.
But...he still has one question, that is, if the three deceased knew each other, why did they never have communication records of contact?
He immediately picked up the phone and dialed Zhang Gong's number.
In less than 3 minutes, Zhang Gong left and returned.
Once assigned to the task force, these veteran detectives are on the battlefield, fighting for their lives, and it is common for them not to go home for 72 hours.
Zhang Gong originally wanted to spend the night in the office, but before he could take a rest, Xu Lin's call came.
"Deputy Team Leader Xu, have you discovered anything?" He hurried back to Xu Lin's temporary office and asked in a surprised tone.
Xu Lin nodded and said: "Team Zhang, please contact the communications company immediately to confirm whether Wen Qi and Jiang Zhenbin are working normally? And...immediately find me all the call records of the three deceased people in the past six months. .Also, invite someone from their company who is proficient in communication payment."
Hearing Xu Lin's words, Zhang Gong was stunned for a moment, and then went to execute it without saying a word.
Even though it was already midnight, he didn't hesitate.
To a criminal policeman, a murder case is as big as the sky.
After Zhang Gong left, Xu Lin immediately contacted Huang Weihan, Hu Gang, and Chen Hua, and called them all to the conference room.
Looking at the three tired faces, he was indeed extremely excited and said: "Huang Zhi, Team Hu, Team Chen, if nothing else, the case has been solved."
"Oh..." Huang Weihan nodded habitually, then glared, stood up and exclaimed: "Xiao Xu, what did you say? Is the case solved?"
Hu Gang and Chen Hua were also stunned.
Chen Hua said subconsciously: "Deputy Team Leader Xu, don't make trouble, how could it be so fast?"
Hu Gang looked at Xu Lin's confident eyes and couldn't help but ask: "Deputy Team Leader Xu, are you serious?"
Xu Lin smiled and nodded.
For a moment, the three of them looked at Xu Lin in shock.
Then I saw him grinning: "I have asked Team Zhang to find evidence. If the clues are still broken this time, then I think our task force may be criticized."
Seeing the relaxed smile on his face, the three of them looked at each other. This guy... couldn't be serious, could he?
Really broken?
