How did Liu Changgen die? A question came from outside the door of the office area of the Criminal Investigation Department of the police station.

The voice is loud and has its own aura, it is Team Cao!

Xu Ran stood up, threw the materials he was sorting out on the table, put his hands on his sides, and stood straight.

The rest of the police officers also subconsciously stopped their work like Xu Ran, and stood up to greet Team Cao with a solemn expression.

Everyone's eyes brushed to the door, only to see a familiar figure, walking quickly under everyone's gaze.

As soon as Officer Cao entered the door, he stood still, his eyes scanning everyone, "Say, how did Liu Changgen die?" ”

No one accosted them, and they all lowered their heads, not daring to look at Officer Cao's eyes.

"Xu Ran, ......what do you say" Officer Cao saw everyone's appearance like this, and directly asked Xu Ran, who had just called.

"Uh......" Xu Ran was angry for a while, "Cao, Team Cao, he ...... Committed suicide"

"Suicide?" Officer Cao raised his eyebrows and his eyes were sharp, "Who will tell me how Liu Changgen committed suicide in the detention room of the police station?" ”

The crows were silent, and the officers didn't dare to breathe.

Knowing that Liu Changgen committed suicide, this question puzzled everyone the most. In the police station, it is difficult to be free, and it is even harder to die.

When they are taken into custody, they will be thoroughly searched and will not be allowed to bring anything into the detention room, especially suspects who have not yet been sentenced, and in order to avoid contact with the outside world and confessions, no communication equipment is allowed to be brought.

Those heavy metals and sharp control tools are not allowed to be carried, and the fear is that the suspect will commit suicide in the police station.

From this point of view, the convict is more comfortable with the sentence. Some of them can even get a mobile phone to play games and send messages.

"Xu Ran, how did Liu Changgen commit suicide?" Officer Cao asked sharply.

Hey, why is it me again, Xu Ran is so depressed! Glancing at Xiao Liu's workstation out of the corner of his eye, Xiao Liu went to the police, otherwise Xiao Liu would have come out at this time.

Everyone didn't speak, and Team Cao grabbed me. Xu Ran stabilized his mind and said:

"Team Cao, the forensic team preliminarily judged that it was suicide by poisoning, and further laboratory tests are still being done. The materials are on your desk. ”

After Xu Ran finished speaking, he secretly glanced at Officer Cao: I saw that the head frowned, and his eyes converged on her, obviously pondering her words.

Then Officer Cao nodded slightly, withdrew his gaze, and strode into his office.

Officer Cao sat in his chair and picked up the information on the table, and he skipped the text part to look through the photos of the deceased taken by the doctor.

In the photo, Liu Changgen's face was red and his body was slightly swollen, but he looked peaceful as if he was asleep.

Seeing this photo, as well as the preliminary autopsy report compiled by the forensic team, Officer Cao was silent.

Man is indeed dead!

When Officer Cao heard the news, his first reaction was disbelief. Subconsciously, he couldn't accept the case he was responsible for, and let the suspect die in the detention room.

Now there is no room for him not to believe!

Officer Cao looked at the photo of the deceased, is this taking poison? What is the clinical manifestation of poison after ingestion?

How did the poison get in? The police station is very strict about the physical examination of prisoners, so they should not be able to bring them in!

Officer Cao couldn't figure it out, so he got up and walked out of the office and rushed to the forensic team.

The officers also paid attention to the movements of the leader while working, and only after seeing the Cao team leave, the officers breathed a sigh of relief. Discussed the case in a low voice:

"Xu Ran, how did you say Liu Changgen committed suicide by taking poison?" Police officer Xiao Zhang asked.

"How do I know, I don't know more than you do?" Xu Ran is not happy, what's wrong today, why is everyone asking her?

"Do you think the boss will hold the guards accountable for dereliction of duty?"

"It's really hard to say, I just don't know which link is the problem, if there is indeed dereliction of duty, the leader is so iron-faced and selfless, he must be held accountable."

"Could it be that Liu Changgen was originally ill, and when he was taken into custody, he was unwell due to external factors, and finally died. It doesn't have to be poisoned, it doesn't look like poisoning, have you seen that Wang Lili was poisoned, and the death was very miserable. ”

Xu Ran listened, and the tragic situation of Wang Lili's hydride poisoning flashed in his mind, tsk, it's really terrifying!

"Okay, don't guess, the forensic team will have an autopsy report soon." Xu Ran stopped the topic.

Officer Cao came to the forensic team and asked about the results of the test on the stomach residue.

Forensic doctor Zhang said that the final report would come out in another half an hour, but no poison was detected from the stomach, and it was all routine food residue.

"Food residue?" Officer Cao was also taken aback, "Is the cause of death poisoning?" ”

"More like some kind of food allergy, to be exact!" Forensic Doctor Zhang pondered for a moment and said, "We found a large amount of mango extract in the stomach of the deceased, and judging from the clinical reaction of the deceased, it is likely that the death was caused by mango allergy!" ”
