The case has progressed to this point, and there is no need to proceed further.

The rest is some things on the process, sort out the existing materials in hand, go back and hand them over to the relevant departments, and ask them to come and take people away.

Originally, things were simple, and Ding Fan was already planning to take a good rest in the office.

Who knows, just sitting at the office desk, the water cup in his hand was not delivered to his mouth, and Wang Qi chased him in from outside.

As soon as he entered the door, Wang Qi said to Ding Fan as if inviting merit: "Boss, what do you think I found?"

While speaking, Wang Qi put all the bags in his hand on Ding Fan's table, took out the contents one by one, and then placed them on the table.

This should be the murder weapon used by Dong Biao when he killed people, as well as the clothes he was wearing at that time. Wang Qi took a brown and yellow dress in his hand, stretched out his hand and pointed to it and said: "The position on the edge, there is really a little blood stain on it, when I was at the scene, it must have been when Dong Biao dragged the corpse, and accidentally stuck the clothes on the ground, so the blood stains were left on it." ”

Ding Fan wore white gloves, carefully took the clothes in his hand, rummaged for a while, nodded, and put the things into the bag again.

I opened another bag as well, took out the contents and checked them one by one.

From the murder weapon to the dried blood stains on the bicycle, everything is enough to show that the culprit of this homicide is Dong Biao.

It's just that these evidences are obviously in front of him, but in Ding Fan's mind, he always thinks back to the moment when Dong Biao was arrested before, and the feeling of relief in his eyes, that kind of picture has been lingering in front of his eyes.

Even Ding Fan could see a sense of relief in his eyes.

For a long time, Ding Fan didn't understand what kind of psychology this person is.

It is said that in the process of interrogation, Dong Biao's situation has always made Ding Fan feel a little wrong, and the indifference at the beginning seemed to be indifferent to how to judge himself.

But in the blink of an eye, he took on everything, although at the last moment, he still tried to struggle in vain, trying to escape responsibility with no evidence.

But after seeing the testimony of the witnesses, the whole person seemed to be completely deflated, but in terms of expression, he was very relaxed, and there was no trace of nervousness in his eyes.

Therefore, what Ding Fan has always suspected is that Dong Biao has mental problems, and during the interrogation, he wrote an investigation direction on the note, telling Qiao Dayong to go over and investigate immediately.

Until now, Qiao Dayong has not returned, and everything is limited to a conjecture.

Just when Ding Fan was checking these physical evidence in Table Mountain, he suddenly found several small medicine bottles in a pile of things.

"Where did you find this thing?" Ding Fan reached out and took the small medicine bottle in his hand, and asked curiously, "Do you know what kind of medicine this is?"

Wang Qi shook his head and said helplessly: "This is what I saw in the garbage heap of Dong Biao's house, as for what this thing is, I don't know, but one thing is certain, that is, this thing, they have a lot of them at home, just this kind of small medicine bottle, I have seen several, I think it is a medicine that has been used for a long time!"

Just when he was talking to Ding Fan about this, Qin Lu walked in from outside, holding a comparison data in his hand, and said to Ding Fan: "It seems that you can already solve the case, Dong Biao's fingerprints have been matched, the fingerprints on the air duct are left by Dong Biao, and the switch on the gas tank also has Dong Biao's fingerprints." ”

Qin Lu came just right, and Ding Fan could ask her about the medicine bottle in his hand by the way.

Qin Lu took the small bottle, took a brief look, put the thing back on the table, and said to Ding Fan: "This medicine has many uses, many hospitals are using it, antiemetic, hypothermia are using this kind of medicine, and it can also be combined with some analgesics, in fact, the most common is still used in the treatment of mental illness, which is what we commonly call psychotic drugs, which are specially used to suppress excessive nervous excitement and agitation." ”

Psychotropics?

Could it be that this medicine was taken by Dong Biao before?

Speaking of which, Ding Fan really felt that Dong Biao's spirit was a little abnormal, and he already had such feelings when he was interrogated just now.

His performance is completely different from ordinary people, but the state of sometimes sober and sometimes crazy makes people very suspicious, and the degree of change is really a bit unacceptable.

It is precisely because of this that Ding Fan called Qiao Dayong to the psychiatric hospital to investigate and see if there is any information about his medical records.

Just when Ding Fan was full of suspicion, the phone on the table rang.

When Ding Fan heard that it was Qiao Dayong's call, he immediately came to his senses, but the result he got surprised him.

Because the results of Qiao Dayong's investigation in the psychiatric hospital were completely unexpected by everyone, and they were even a little puzzled.

In the hospital's records, Dong Biao had no record of psychiatric treatment at all, but found Dong Biao's wife's psychiatric treatment record in the hospital.

And it was within the last year, and in terms of time, the last time Dong Biao's wife was admitted to the hospital for treatment should be a few days after his daughter lost her sight.

Dong Biao's wife is mentally ill, and at first glance it doesn't seem to have anything to do with the case, but if you think about it carefully, you will find something wrong inside.

It's just that what's wrong with it, and I still can't figure it out for a while.

Ding Fan even couldn't figure it out, why did Qiao Dayong investigate Dong Biao so well, and finally turned into an investigation of his wife?

In fact, at the beginning, Qiao Dayong investigated Dong Biao, but he didn't find the medical record, and suddenly remembered that when he was looking for Dong Biao's wife before, the look on this woman's face was a little abnormal, so he investigated it by the way.

Unexpectedly, I really found this person's medical records, and it was not a long time, so I didn't have time to think about it and called Ding Fan directly.

It's just that he didn't expect that what he investigated would bring so many questions to Ding Fan.

Ding Fan sat alone in the office, thinking about this case, it seemed that everything had been investigated very clearly, and all that remained was the transfer of the case.

But Ding Fan has always felt that there seem to be a lot of questions in this case, and there are too many things that he can't figure out.

Just when Ding Fan was thinking about these things alone in the office, Lu Zhi walked in from outside, with a warm smile on his face, and asked him: "What's wrong with you? The case has been solved, why are you still here with a bitter face?"

"If the case is closed like this, it can be closed!" Ding Fan said helplessly: "It's just that I have always felt that there are a lot of strange things in this case, and I can't understand it at all." ”

What do you mean?

Could it be that there is something hidden in this case?

At that time, when Lu Zhi heard Ding Fan say this, his brows had already twisted into a knot, and he didn't know what to say for a long time, so he reached out and picked up the cigarette on Ding Fan's desktop and smoked it, and the whole person instantly became quiet, without the excitement before.

Just when the two were silent, Qiao Dayong came back from outside, stretched out his hand to wipe the sweat on his forehead, and said eagerly: " Boss, I found it, I followed what you said, I visited near Dong Biao's house, and sure enough, the neighbors around said that his wife was a little nervous, and she had a few illnesses when she was at home, and some time before the crime, the couple often went out together, or at night, at that time, they just said that they went to a relative's house, but these two people rarely visited the door before, so these two people are very abnormal. ”

"And so it was. Ding Fan leaned back on the chair, his eyes were thinking about something blankly, his eyes suddenly lit up, and he hurriedly said: "Inform the Technical Investigation Department to re-investigate the fingerprints extracted from the gas canister before, and it should not be just Dong Biao's fingerprints on it." ”

Qiao Dayong agreed, turned around and ran straight to the Technical Investigation Department.

As soon as Qiao Dayong went out, Lu Zhi came up to Ding Fan and asked in a low voice, "How do you see it?"

Ding Fan reached out and took out a photo on the table, put it in front of him, and said: " The bloodstains on the ground were left behind when the murderer moved the body, take a closer look at the drag traces of this long strip, it is obvious that there are a few pauses, the deceased Guo Dazhong weighs about one hundred and seventy pounds, if Dong Biao wants to drag, it will not take any effort at all, but the pauses in these places are obviously a bit much, and the other is that the door of his house is bowed on the door, if you want to drag the body in, you must need someone to help, otherwise the noise will be a little loud, the most important point is that Yang Xiaojuan, who died on the bed, although the slash on her face came from the same murder weapon, but the slash on her face was very different from the fatal injury, and she didn't notice it at firstAt first, I just thought that Dong Biao was in a sick state after the killing, so I did this, but after the investigation, I learned that the person with neurological diseases was not Dong Biao at all, but his wife, and the person who appeared at the scene of the murder should not be just one person, but two. ”

Lu Zhi nodded silently, glanced at the watch in his hand, and said a little nervously: "I have notified the department above to come and hand it over, we are now short of a piece of evidence to sort out and summarize, I'm afraid it's a little too late in time, are you sure?"

"Time is indeed a bit tight, and I have already called someone to investigate Dong Biao's wife. Ding Fan simply cleaned up the things on the table, stood up and said, "Liangqi also called someone over, as long as she doesn't run, the time is completely in time." ”

Lu Zhi took a deep breath and said firmly: "Okay, you have the final say in this case, I'll help you buy time, try to drag the people over there, everyone hurry up a little time, it should be in time." ”

Ding Fan reached out and took the bag, walked to the door, took a deep breath, turned around and said, "It must be in time, I won't disappoint you." ”
