At dawn, the police car screeched to a halt in the middle of the ring highway.
Instantly, everyone's mood dropped below freezing point.
After initially surveying the scene last night, Jiang An concluded that the deceased had died from tetramine poisoning.
Moreover, after on-site analysis and discussion, as well as post-mortem examination, this view was further corroborated.
Especially the experienced old forensic expert, Wu You, also deeply endorsed this conclusion.
Actually, Li Jian internally chose to believe it.
However, as the captain of the criminal investigation team, his personal stance represents the organization.
Hence, he had maintained a neutral stance at the death scene.
But!
This abrupt result indeed shocked everyone in the car.
Li Jian, Jiang An, and Zhang Yean all turned to Wu You, looking incredulous.
In everyone's hearts, there were only five words: "How is this possible?"
Jiang An was even more baffled.
In his understanding, the causes that could lead to extreme muscle spasms and rigidity are not many.
Apart from rare existing diseases, there's only this poison.
Captain Li Jian frowned and asked, "Old Wu, is your system upgrade reliable?"
Wu You said, "The system should have no problem."
"This system was upgraded three months ago, has been used for 90 days, and the conclusions have all been accurate."
Zhang Yean said, "Mr. Wu, could this toxicology analysis equipment, like a computer, sometimes crash or display garbled text?"
Wu You shook his head.
"I think the possibility is very small."
After a long pause, Jiang An said in a deep voice, "Mr. Wu, could it be that the quantity of samples we extracted is insufficient?"
Wu You thought for a while and said, "That is a possibility."
"If the toxin is unevenly distributed within the stomach lining, then there might be a certain probability with the extracted specimens."
"If the distribution of the toxin in the specimen is insufficient, the machine won't be able to concentrate."
Upon hearing Wu You and Jiang An's discussion, Li Jian quickly said, "In that case, let's go back to the forensic autopsy center immediately."
"I suggest you put the entire stomach and food contents of the deceased into the machine for testing to avoid any oversight."
Subsequently, Captain Li Jian said, "I'll turn around immediately and head back."
Seeing Captain Li turning the steering wheel, Zhang Yean reminded, "Captain, this is the ring highway!"
Captain Li turned the car around, accelerated, and said, "We can't worry about that now; solving the case is urgent."
7:30 in the morning.
Mr. Ma, having had breakfast, walked out the door with his briefcase.
Normally, due to busy work, there's no dedicated time for exercise.
Walking to and from work is his only chance to exercise.
Just as he stepped out of the neighborhood gate, he saw Mr. Wan Kai from the city's publicity department.
"Mr. Ma! Morning!"
"Mr. Wan! Morning!"
The two were classmates at the police academy, both working at the Jiangcheng City Bureau, and lived close by, both having the habit of walking to work.
After walking together for about five minutes, Wan Kai said, "Mr. Ma, I heard last night a female body was found in the jurisdiction of Zizhu Police Station."
"Oh?"
Mr. Ma was taken aback.
Suddenly, he remembered entertaining last night, and amid clinking glasses, he thought he felt his phone vibrate.
But at the time there were important guests present, so he didn't answer the call.
Subsequently, he took out his phone from his bag, turned on the power button, took a look, and indeed found three missed calls.
These three missed calls were all from Li Jian.
Wan Kai said, "Mr. Ma, this month we have the provincial peace station evaluation, and this year the main unit being promoted is the Zizhu Road Police Station."
"That's great! How are the developments?"
Wan Kai replied, "The evaluation materials were all submitted to the province a week ago and are in the review stage."
He then changed the topic, "The provincial peace station contest is held annually, and we've been unselected for five consecutive years."
"This time, promoting Zizhu Road Police Station is the only station selected city-wide."
"If a homicide occurs in the precinct at this critical selection moment, it will almost certainly be a veto."
Upon hearing this, Mr. Ma paused and asked, "Is the impact that significant?"
With a solemn expression, Wan Kai nodded.
"Mr. Ma, you oversee criminal investigations and are my old classmate. Please be careful in determining the nature of the death."
"If the female body discovered on Zizhu Mountain last night is determined to be suicide or sudden death, there will be no impact on this evaluation."
"If it's determined to be a homicide, there's almost no hope for selection."
Upon hearing this, Mr. Ma's expression became serious, and he fell into contemplation.
Although he doesn't oversee publicity work, the 'Peace Station' is an honor for the entire city's police and must be given great importance.
Immediately, he swiped on his phone screen and dialed Li Jian's number.
At the same time.
Director Yang Guang, along with two officers, hurriedly ate fried dough sticks and soy milk at a breakfast stall and quickly took action.
For the selection of the 'Peace Station,' Director Yang Guang was even more eager and expectant.
Bear in mind, Jiangcheng City has a total of 208 police stations.
Zizhu Road Police Station stood out after three internal selections, over many hurdles.
This time, it represents the Jiangcheng Police Team, participating in the provincial finals.
For Director Yang Guang, this is a significant mission and a rare honor.
According to last night's plan, they first arrived at the home of the informant, Zhang Guilan.
"Ms. Zhang, please recall how your handbag was stolen?"
Zhang Guifang said, "At that time, a few sisters and I were dancing in the square, with the handbag placed on the side stage. After the dance, I found the handbag was gone."
Yang Guang asked, "Ms. Zhang, was there anyone unfamiliar passing by at that time?"
Zhang Guifang fell silent in thought. After two minutes, she said, "I remember now, during the break midway through the dance, I saw a man wearing a baseball cap and carrying a backpack."
"Do you remember his height or physique?"
Zhang Guifang said, "I estimate he's about 170 cm, quite slim."
After a slight pause, she added, "Oh! Right!"
"I remember he seemed to have a bit of a limp when he walked."
From Zhang Guifang's recollection, Yang Guang's eyes narrowed slightly, and he turned to the officer beside him and said, "I think I know who that man with a limp is."
"He's a habitual thief, just released last month."
Subsequently, Yang Guang said, "Let's go! We'll see him immediately!"
At this moment, inside the Jiang City Forensic Autopsy Center,
Captain Li Jian, with a worried expression, was on the phone, reporting to Mr. Ma.
After initially understanding the situation, Mr. Ma asked, "Can we now determine if it was homicide, suicide, or accidental sudden death?"
After a brief contemplation, Li Jian hesitantly answered, "Mr. Ma, the toxicology analysis is still being tested. We will report to you immediately when there's a result."
Mr. Ma earnestly advised, "Li Jian, determining the nature of this death is very important and crucial."
"Your conclusion not only affects the handling direction of this case but also the collective honor of the Jiangcheng Police Team."
"The provincial peace station evaluation is at a critical stage; we cannot make any mistakes."
"You must be careful, very careful!"
"Yes!"
Li Jian's gaze settled on the toxicology analysis instrument.
