After sorting out the ideas, all that remains is to find out the survey.

Early the next morning, Lu Ke led a team to Dujing Biopharmaceutical Co., Ltd.

When an employee in the company dies, it is normal for the police to come to the company to investigate.

And Ren Jianyun also sat in the office, waiting for the police to come to the door.

Under the leadership of the assistant staff, Lu Ke and Mo Yufei pushed the door and walked into Ren Jianyun's office.

His office is very large, with good lighting and simple and tidy furnishings. The most eye-catching thing is the floor-to-ceiling window, standing in front of the window, you can overlook most of Jing'an City.

Ren Jianyun sat behind a wide desk in a suit and leather shoes, looking at Lu Ke and Mo Yufei who had just entered the door.

"Of the Criminal Investigation Detachment of the City Bureau."

The two walked into the office, showed their ID and identified themselves.

Ren Jianyun also stood up symbolically, and politely stretched out his hand to beckon the two to sit down.

Immediately afterwards, the assistant brought two cups of tea for the two.

The employees in the company died, although Ren Jianyun was not the boss of the company, but after all, he was Sun Jinyu's direct boss, and it was a bit surprising that he was so bland in the face of the police.

"Sun Jinyu is an employee of the company, right?"

Mo Yufei spoke slowly, knowingly asking.

Ren Jianyun smiled faintly and nodded, counting as an answer.

Mo Yufei continued to ask: "Do you know that Sun Jinyu was killed? ”

Ren Jianyun was still expressionless, and replied lightly: "I know." ”

Faced with Ren Jianyun's attitude, Mo Yufei felt a little short of words for a while.

The most important thing for the police to investigate and inquire is to change their thinking according to the other party's answers and attitudes, as well as changes in micro-expressions and loopholes.

But now, obviously, it was a very difficult investigative inquiry.

Usually, when encountering this situation, Lu Ke next to him will answer in time, which is not a help, but a way to investigate.

Two people, two investigation tones and attitudes, two investigation directions, one white face and one red face are also common tactics used by the police, and there are often major discoveries.

But Lu Ke beside him didn't speak, a little distracted, his eyes were a little dull, and he didn't know what he was thinking.

At this time, Lu Ke's gaze fell on the cabinet behind Ren Jianyun.

Sometimes, looking at the placement of items in a person's office can give you a lot of clues.

The books, ornaments, certificates, archives, documents, etc. in the cabinet all illustrate the identity and character of the owner from the side.

But on the cabinet behind Ren Jianyun, there was red wine and a complete set of wine utensils.

It stands to reason that this is a personal hobby, and Ren Jianyun, as a senior executive of a company, has nothing to put some of his favorite red wine in the office.

It's just that something as expensive and easily damaged as red wine is better to keep at home?

Lu Ke didn't speak, Mo Yufei had to change a way of investigation and inquiry, that is, let Ren Jianyun take the initiative to speak, and say more.

Mo Yufei froze and threw out a question: "How is Sun Jinyu?" ”

Ren Jianyun pursed his lips, and his answer was still bland: "He has a good personality, he can get along with everyone, he is also very serious at work, and he is a very reliable person." ”

Mo Yufei nodded and continued to ask, "Does he have any enemies in the company?" Is there a contradiction with whom? ”

Ren Jianyun replied in a low voice: "I haven't heard of any enemies in him, and I haven't heard of anyone he has conflicts with. He is an employee of the marketing department, because of the needs of the work, he will meet all kinds of people, so his character is very well tempered, not to mention contradictions, even he has never seen anger. ”

After listening to Ren Jianyun's words, Mo Yufei instantly became serious, staring at him with a dead gaze: "Is there any contradiction between Sun Jinyu and you?" ”

Ren Jianyun was stunned for a moment, this was also the first time he made an expression, but his answer was still bland: "Me? We don't have a contradiction. ”

This time it was Mo Yufei's turn to smile faintly: "Then why are you quarreling?" ”

Ren Jianyun frowned, a little puzzled: "Quarrel? ”

Mo Yufei asked coldly, "Didn't you quarrel?" ”

Ren Jianyun swallowed a mouthful of saliva and was silent.

He was thinking about it too, and there was a hint of panic in the slight change in his expression.

Investigation and questioning, and even interrogation, are like this, not one question and one answer, but to find more truth in the continuous transition between offense and defense.

Mo Yufei struck while the iron was hot, and every sentence entered Ren Jianyun's heart: "In the past six months, you have often been in and out of Sun Jinyu's house, and you have often quarreled with him, what's going on?" ”

Ren Jianyun adjusted his sitting posture and did not answer this question.

But he knew that in the eyes of the police, Sun Jinyu's death was inseparable from himself.

A smile appeared on the corner of Mo Yufei's mouth: "There was only one person's fingerprint at the scene of the crime, except for Sun Jinyu, and he was poisoned by drugs, so compare the fingerprints later......"

Without waiting for Mo Yufei to speak, Ren Jianyun suddenly opened his mouth and interrupted her: "I didn't kill him." ”

Mo Yufei was slightly surprised, and at the same time a little excited, and said coldly: "Now all the evidence points to you, if you don't cooperate with our investigation, then you can only ask us to go to the interrogation room to talk." ”

Ren Jianyun took a deep breath, leaned back, slowly leaned back on the chair, and said slowly: "He is the director of the marketing department, and it is normal for me to talk to him about work." But I don't know why, every time we had a good conversation, he suddenly got angry, like crazy. ”

Mo Yufei was stunned, if according to Ren Jianyun, every quarrel was initiated by Sun Jinyu?

Lu Ke finally came back to his senses, and also noticed this, and spoke at the right time: "As his direct boss, even if you are talking about work, why do you want to go to his house to talk?" Isn't it the same here? ”

After speaking, Lu Ke pointed to the office.

Ren Jianyun let out a long sigh, as if he had a stomach full of bitter water and no place to vomit.

He said in a deep voice: "At first, we were talking in the office, but Sun Jinyu didn't know why, and every time he suddenly seemed to go crazy, making the company employees think something was wrong. Really, I wondered if he had some mental illness at one point, and he was like a mad dog at every turn. So later, when I was not at work on the weekend, I went to his house to talk to him about work. Although we are superiors and subordinates, as the head of the scientific research team, I have dealt with the problems in the company, which is also very helpful to my work. And I have known Sun Jinyu for many years, and we have a good personal relationship, and I have never put up any shelf in front of him. ”

After Ren Jianyun finished speaking, he then added: "By the way, he has a cleaner at home." ”
