Detective: Open your eyes, I am handcuffed in the interrogation room

Basketball court nearby.

Several people sat down.

Zhao Jianhui kept looking at Chen Yi and others. The word "provincial department" really shocked him. After a year, had the police investigating the case been replaced by the provincial department?

"Zhao Jianhui, is that right?" Chen Yi said, looking at the young man in front of him from a close distance.

In his early twenties, there is still a trace of childishness and innocence on his face. Through the brief exchange just now, it can be seen that Zhao Jianhui's character is enthusiastic and cheerful. If it were not for the fact that he was facing the police, he would There should be no shortage of smiles on your face.

He is already a senior and will soon enter the society. Compared with freshmen and sophomores, Zhao Jianhui is a little more mature.

It is worth mentioning that Gao Xiaofei's boyfriend and Zhao Jianhui are both her juniors. Both boys were juniors last year.

Zhao Jianhui nodded. After learning the provincial and ministerial identities of several people, he became more cautious.

"Studying environmental science?" Chen Yi asked again.

Zhao Jianhui nodded again: "It was adjusted."

Chen Yi: "What are you going to do after graduation?"

He didn't immediately improve Xiaofei.

Zhao Jianhui shook his head: "I haven't decided yet. Let's go back to my hometown and take a look. It should be to take the teacher or civil servant exam."

Chen Yi: "Did the family ask for it?"

Zhao Jianhui: "Yes, my father is a teacher and my mother works in a hospital. They want me to be more stable and stop running around. I am an only child."

This kind of family background has surpassed that of many, many people. It is not as good as the rich second generation, but it can be comfortable for a lifetime.

Chen Yi knew the information and it was just a casual chat to enhance mutual familiarity.

His mother works in a hospital, so Zhao Jianhui may know more medical knowledge than his peers.

For example, the reaction between vitamins and pentavalent arsenic.

After chatting for a while, Chen Yi finally turned the topic to Gao Xiaofei. Zhao Jianhui knew that he couldn't avoid it and sighed: "Her death really has nothing to do with me. I like her. How could I kill her and be angry?" …I am indeed angry, but I don’t have the guts to kill someone.”

In a year, everything that needed to be investigated was investigated, and everything that needed to be asked was asked. Chen Yi did not choose to repeat it, and began to ask questions in a targeted manner: "For the last meal, you took Gao Xiaofei to eat seafood."

Zhao Jianhui: "Yes."

Chen Yi: "Why choose seafood? Do you like it or does she like it?"

This question is not on the file.

Zhao Jianhui showed subtle expressions on his face and quickly answered: "She likes it. She likes seafood very much."

Chen Yi: "Does Gao Xiaofei often eat seafood in college?"

Zhao Jianhui: "No, her family situation is not very good. Her parents are gone and only her grandma is left. She is reluctant to eat."

Chen Yi: "You know her quite well."

Zhao Jianhui forced a smile: "After all, I have been chasing her for two years, from my sophomore year to my junior year, so I must know her well."

Chen Yi looked at him and suddenly spoke very quickly: "Seafood contains high levels of pentavalent arsenic, and the reaction between pentavalent arsenic and vitamin C can form highly toxic trivalent arsenic, so seafood and vitamin C cannot be eaten together. Yes, what is your purpose?"

Zhao Jianhui was startled for a moment, then his expression changed slightly.

"Wha... what pentavalent arsenic and trivalent arsenic??"

The smile that appeared on his face became stiff and unnatural, his eyes became wandering, he did not dare to look at Chen Yi, and he unconsciously clasped his hands.

After all, college students are college students. Faced with experienced criminal police, it is difficult for lies to fool them.

Of course, this also indirectly shows that the possibility of Zhao Jianhui being the murderer in this case is almost gone.

Because of his poor psychological quality, he deliberately brought Gao Xiaofei to the seafood buffet restaurant, and the Suicheng City Bureau found no clues or evidence from him. Together, these three aspects can rule out Zhao Jianhui's suspicion of committing the crime.

"To be honest, what do you want to do?" Chen Yi asked, with a coldness in his voice.

Zhao Jianhui's facial muscles moved, probably gritting his teeth: "I'm telling the truth, I don't understand what you mean."

What Zheng Congliang said before was correct. As long as the person involved does not admit this kind of subjective life behavior, it is impossible to obtain evidence. It is just a piece of seafood. Zhao Jianhui cannot be charged with intentional injury for no reason.

Unless, he admits it.

Looking at this posture, it is impossible to recognize him.

However, if Zhao Jianhui is left in the Municipal Bureau for continuous interrogation for dozens of hours, the psychological defense will collapse quickly, but there are still many variables when it comes to sentencing. Lawyers will help. This matter all depends on Zhao Jianhui's mouth.

Taking vitamins is Gao Xiaofei's personal behavior. She likes to eat seafood, so Zhao Jianhui took her to a seafood buffet. It was reasonable and reasonable. Although there was subjective criminal intent, there was no objective criminal fact.

Therefore, Chen Yi will not waste time on him and just leave it to Zheng Congliang. There are more important things to do now.

"Gao Xiaofei has a good relationship with her boyfriend, right?" Chen Yi said.

Seeing that the other party changed the topic, Zhao Jianhui breathed a sigh of relief and nodded: "Yes, very good. Ever since she established her relationship with Qian Changdong, she rarely pays attention to me."

Qian Changdong, Gao Xiaofei's boyfriend, Zhao Jianhui pursued Gao Xiaofei for two years without success, and Qian Changdong knew Gao Xiaofei for only a week and became inseparable.

Emotions are like this. Persistence is actually useless. Persistence only brings emotion and no emotion. This has nothing to do with the length of time you have known each other.

Qian Changdong is quite rich and handsome, but I don't know whether Gao Xiaofei chose Qian Changdong because of money or people, or both.

If we analyze it according to normal logic, it is more likely because of money.

People will pursue what they lack. Since the death of Gao Xiaofei's parents, her family's financial situation has plummeted. It is difficult to survive on her grandma's retirement salary.

Precisely because of this, Qian Changdong's suspicion of committing the crime is not high, and no reasonable motive can be found.

What kind of conflicts can there be between college lovers? Unless she was cuckolded, the Suicheng police checked in this direction and found no signs of cheating on Gao Xiaofei. She was very satisfied with her boyfriend Qian Changdong.

In other words, the motives are very hidden and the two of them have known each other a long time ago.

Qian Changdong also needs to be met, because Gao Xiaofei's appearance is not particularly outstanding. The reason why the two became a couple needs to be confirmed again.

"Tell me about Gao Xiaofei in detail, starting from the first day we met. I want all the information you know."

More than half an hour later, Zhao Jianhui left as if running away.

Regarding the seafood matter, Chen Yi would tell Zheng Congliang after returning that since Zhao Jianhui had this intention, he would have to bear the consequences.

Once he has a criminal record, it will be impossible for him to take the official examination. A certificate of no criminal record cannot be issued, even if he is detained by public security.

Now, what all units require is a clean criminal record. Although illegal records do not affect the situation in principle, when the police station issues a certificate of no criminal records, they will note the illegal records in very detail.

Therefore, detention for gambling, detention for drug abuse, detention for prostitution, detention for drunk driving, etc., as long as you leave the filing information, even if it is just a fine without detention, regardless of the reason, it will not pass the unit review.

This is the price of breaking the law, and the cost is still very high.

"Gao Xiaofei is in quite a bad situation." Zhuge Cong was the one who spoke. "Some people want to kill her, and some want her to be poisoned. If they really want to go to the line, Zhao Jianhui might not be suspected of attempted murder."

Everyone saw that Zhao Jianhui was lying. His acting skills were very poor. Because of his poor acting skills, he probably wasn't the poisoner.

Chen Yi: "Let Zheng Congliang handle it. We won't waste time with him. Let's go find Qian Changdong. Fu Guoyong and Zhuge Cong will go there."

Two people: "Yes, Captain Chen."

They turned around and were about to leave when the sound of a basketball falling was heard not far away. Four or five male college students wearing basketball uniforms walked towards them while beating the basketball.

Coincidentally, among them was Qian Changdong.

"Team Chen."

"Um?"

Zhuge Cong motioned Chen Yi to look over there, and the latter turned his head and said in surprise: "What a coincidence, Qian Changdong!"

he shouted.

Hearing the shouting, Qian Changdong subconsciously looked over and found that they were several adult men.

The smile on his face solidified, and the familiar feeling came back.

As Gao Xiaofei's boyfriend, the Suicheng City Bureau looked for Qian Changdong when investigating the case last year, and even listed him as one of the major suspects from the beginning.

After final investigation, the suspicion was eliminated. He had the conditions to commit the crime but no motive. He also had no intention to purchase trivalent arsenic and no suspicious signs.

"Why."

Qian Changdong and Zhao Jianhui had similar reactions. He could be seen sighing deeply and walking over helplessly.

Several friends had no intention of playing basketball and watched silently from a distance.

"Are you...comrade police?" Qian Changdong asked.

Chen Yi looked at Qian Changdong. He was a sunny boy with good looks and a good figure. He was tall, rich and handsome.

There are some doubts about whether Gao Xiaofei can be attracted to Gao Xiaofei under such conditions.

The police should think about problems from a realistic perspective instead of praising love. There are so many stories about rich and handsome men falling in love with ugly ducklings. They are all lies and only appear in idiotic TV series.

Don't let a bunch of white and rich beauties chase the ugly ducklings? too fake.

Maybe, but it's extremely unlikely.

"Sit down and let's talk about Gao Xiaofei." Chen Yi answered Qian Changdong with practical actions.

Qian Changdong sat down obediently and looked very well-behaved.

"Isn't Captain Zheng here? You guys are very unfamiliar." He is a familiar person, and his words are neither humble nor overbearing. It should be related to the influence of family education.

Chen Yi: "We are from the provincial department."

Qian Changdong was surprised: "Provincial department? The boss of the provincial department came to investigate in person. The murderer will definitely be caught."

This is a very talkative boy.

Zhuge Cong and the others looked at each other with strange expressions. Compared with Qian Changdong, Zhao Jianhui was instantly killed in all aspects, otherwise Gao Xiaofei would have chosen Qian Changdong.

Any girl would probably choose Qian Changdong.

Chen Yi: "Don't be poor, tell me something we don't know."

One year has passed for Qian Changdong to get out of the shadow of the case. At this moment, he is smiling brightly: "Comrade leader, I have indeed said everything that needs to be said. There are really no new clues to provide. How about I hide it?" I also want to know who killed Xiao Fei.”

Chen Yi: "What is your reason for pursuing Gao Xiaofei?"

Qian Changdong: "I like it. If I don't like it, can I pursue it?"

Chen Yi: "Tell the truth."

Qian Changdong wondered: "Is it because I don't like it?"

Chen Yi's eyes narrowed slightly: "I told you, don't be poor like me. Why are you pursuing Gao Xiaofei? I saw it when I entered the campus. Your school was formerly a normal university. It was later upgraded to a comprehensive university. There are many beautiful girls. It's not the turn. It’s not Gao Xiaofei’s turn, Qian Changdong, we are investigating a case, do you think it’s just chatting?”

Qian Changdong was shocked by Chen Yi's momentum, and murmured in his mind that it was the provincial department, which was quite different from the local police.

"This..." He scratched his head.

Chen Yi: "If you don't tell me, just change the place."

Hearing this, Qian Changdong said quickly: "No, comrade leader, it's not necessary. I really like Gao Xiaofei... Okay, I know what you mean. The reason for liking her is that she is very mature, and I like mature girls. "

Chen Yi: "I have an Oedipus complex when I like mature girls. Is your father often away from home?"

Maturity is indeed one of Gao Xiaofei's labels. Her parents died young and lacked care and protection, so her level of independence is much higher than that of her peers.

Qian Changdong's smile faded. This matter was not mentioned during the police investigation last year. It seemed that they were preparing to dig deep into everyone around Gao Xiaofei.

"Yeah." He nodded slightly.

Seeing that Qian Changdong was not in a good mood, Chen Yi did not ask further: "Did you say that you didn't notice anything unusual about Gao Xiaofei when you were with her, including her lack of family ties? It stands to reason that students whose parents have died have different personalities and psychology. There are certain flaws in the meeting.”

Qian Changdong shook his head: "No, she is very optimistic. She only mentioned her parents once. After learning that her parents were both dead, I never talked to her again. It is not a good thing to expose people's scars."

Chen Yi: "Do you think Lin Kaiyue might be the murderer?"

Lin Kaiyue is Gao Xiaofei's roommate and the only female college classmate who had conflicts during the investigation.

The contradiction is that Lin Kaiyue can't stand Gao Xiaofei's mature style. He seems to have experienced more than everyone else and likes to preach.

Since Gao Xiaofei and Qian Changdong confirmed their relationship, Lin Kaiyue's relationship has become even worse due to envy and jealousy.

The motivation isn't quite there, but it's there.

Hearing this, Qian Changdong quickly shook his hands: "I don't dare to say this nonsense. It is true that Gao Xiaofei and Lin Kaiyue have conflicts, but I don't know whether she poisoned her or not. When I mention this matter, I I’m just scared, I’ve even taken one of that bottle of vitamins.”

"Um?"

This sentence reminded Chen Yi whether the murderer needed to avoid manslaughter, or the target was not Gao Xiaofei at all, or there was more than one target.

Judging from the quantity in the bottle, the murderer chose to poison the bottle when it was about to be emptied, ensuring the fastest efficiency. Based on probability, it was estimated that the poisoning time should be Thursday, Friday, and Saturday.

Gao Xiaofei died of poisoning on Sunday. She was a local and returned home on Saturday. Her cousin was there at the time to visit her grandma, so her cousin was also suspected, and the suspicion was not small.

This person is the focus of Chen Yi's attention.

"Do you eat it often?" he asked.

Qian Changdong: "That's not true. I only ate it once. She gave it to me and asked me to try it. I haven't eaten it since then. Fortunately, I didn't..."

Chen Yi: "When did you eat it?"

Qian Changdong: "Forgot, it was a month before she died."

It's a bit unnecessary to worry, as the poison must not have been poisoned at that time.
