Liu Jian watched at the door of the office, and there were not many people in the office at this time.

Liu Jian should have said it outside, Ding Fan lost his temper inside, and if he still has the courage to come in at this time, there will be even fewer people, except for her, there will be no one else.

Liu Jian, this kid is very ghostly, and as soon as he looks at Ding Fan's eyes, he knows that it is inconvenient for him to be present now.

Because Ding Fan is going to get angry and clean up Captain Zhao, he is present, and Captain Zhao must have no face.

Ding Fan is okay, after all, where is the police rank, even if the leader reprimands his subordinates, Captain Zhao can get by in his heart, and he will not be too faceless.

But the premise is that he can't be present, otherwise he will not be able to get off the stage.

Tell him to go out, firstly, to save some face for Captain Zhao, and secondly, to ask him to watch outside, and not to ask people to come in or hear outside.

No matter who is coming outside, he can think of some way to stop people as much as possible, but there is such a person, even Ding Fan has to face it carefully, where does he have the ability to stop people!

So for Qin Lu's sudden indication, let alone Liu Jian, even Ding Fan is a little big.

After all, Ding Fan himself felt that he owed Qin Lu very much, he couldn't say a lot of things directly, and he had to try to take care of her emotions, which could be regarded as a little compensation!

And Captain Zhao saw Qin Lu come in, and glanced at Ding Fan a little nervously.

To be honest, at such an old age, being cleaned up by Ding Fan, a young leader, he really felt a little uncomfortable in his heart.

But Ding Fan has the ability, and when he says a few words to him, he still listens to it.

But all this is when no one is present, and if someone is here, if Ding Fan is saying something, his face will not be able to be saved at all.

So at this time, he was very afraid that Ding Fan would say something to him, they were all men, and he was not blind and couldn't see Ding Fan's feelings about Qin Lu.

If Ding Fan said something to make him uncomfortable in order to find some face in front of Qin Lu, then it would be a little difficult for him.

Fortunately, Ding Fan just glanced at him and didn't say anything, just waved his hand at him, signaling that he could go out first: "Check the situation on the other side of the road as soon as possible, what happened five years ago, although it is a little difficult, but you look for a relationship, I think it should be done, let's do it today, and the rest of the things will be said later." ”

Ding Fan didn't plan to say anything, this was naturally a good thing for Captain Zhao, nodded, and left the office after packing up his things.

After Captain Zhao left, Qin Lu sat in front of Ding Fan, looked at him with interest for a while, and Ding Fan was uncomfortable, and then said: "I can't see it, Director Ding is so powerful now!"

When Ding Fan heard this, sweat suddenly appeared on his face, and he laughed a little embarrassed.

"How can it be as serious as you say, I just want to find out those who have something to do with this case as soon as possible, it is not as serious as you think, where is the official authority. ”

Looking at Ding Fan's somewhat embarrassed appearance, Qin Lu seemed to be a little unsatisfied.

But this is an office after all, not a place for her to joke, she still has a little discipline, put down a document in her hand, and pushed down in front of Ding Fan.

"This is the evidence recovered at the scene yesterday, I did some detailed analysis, there are indeed blood stains left in the sewer pipe at the scene, and it has been proved that the blood is this family of five, but it is a little chaotic, it should be left behind when the murderer cleaned it after killing people. ”

The things sent by Qin Lu, in addition to the results of analysis and comparison, also had a small section of pipe.

Ding Fan took it in his hand and looked at it, this should be the one that connects to the sewer, but there is a bend on this pipe, which happens to be at the bend position

, there are some traces of blood remaining, which have been completely coagulated for a long time.

If it weren't for the location of this turn, this bloodstain might not have been left at all.

"God forbid, thanks to the location of this turn, is there anything else besides these blood stains?"

As if he already knew that Ding Fan was going to ask this question, Qin Lu casually took out a small piece of paper from his pocket and put it on the table.

"In addition to the bloodstains, we also detected a little residue of grease inside this sewer. It's exactly the same as the little residue on the wall. ”

Grease?

In this way, on the wall of the cubicle, what remains is grease, and it is very likely that the murderer accidentally left it on it.

It's small, but it's not small!

Ding Fan held a small piece of paper in his hand, looked at it carefully for a while, and called Liu Jian in by the way.

"Can you find out where the grease is used for this?"

Ding Fan thought about all the places where this thing could be used, but because he didn't know much about the local area, this kind of thing still needed someone to help check it in the end.

Liu Jian has already sorted out a lot of local information, and I don't know if there will be clues on his side.

"I've found someone to do a comparison, but this kind of oil seems to be a general-purpose oil, which is actually used in many places, and the rest depends on their comparison results, hoping that there will be a little other thing mixed in it, otherwise it will be difficult to make an accurate judgment based on this little thing." ”

Ding Fan nodded silently and glanced at the time.

It's not early, yesterday I had already stayed up all night, plus two days of time, everyone was already very tired.

That's it for today, go back and rest, and continue the investigation tomorrow!

"That's it, tomorrow after the comparison over there comes out, take a copy out to Captain Zhao or Director Hu, and ask him to arrange someone to check where this oil will be used. ”

If Ding Fan is not mistaken, the places where this thing can be used should generally be some factories and mines such as processing plants.

In this kind of place, it is a bit troublesome to investigate, and it is better to have Director Hu come forward.

After explaining this, Ding Fan planned to take everyone to rest after work first.

But Qin Lu didn't seem to have something to say yet, and when Liu Jian went out first, he stretched out his hand and pulled Ding Fan back.

"I've been in touch with the previous medical examiner, asked a little bit about the case, and heard something different. ”

Something different?

Ding Fan looked at Qin Lu in surprise, and for a while he didn't understand what she meant by this difference.

"Before the deceased Guo Cuihua died, it was possible that he was drugged!"

When Ding Fan heard this, he was not the slightest surprised, but took it for granted.

As if he had known about this for a long time, he just nodded lightly, not at all surprised as Qin Lu imagined.

"Did you know before?"

"No, how can you possibly know, you just saw this forensic doctor today, where did I go to find this person before?"

Ding Fan shook his head and simply cleaned up the things on the table.

After pondering for a while, he turned around and glanced at Qin Lu before he said to her: "I was a little curious before, why Guo Cuihua was sleeping all the time during the murderer's murder, and it seemed that he didn't hear a sound at all. At first, I wondered if I had closed the door while I was sleeping, so I didn't hear anything outside, but then I found something inside the evidence box, so I had a little guess. ”

Ding Fan said as he took out an evidence bag from the box on the table.

Qin Lu saw that this was a medicine specially used to relieve pain.

Generally speaking, there are very few people out there who will use this medicine.

In the previous autopsy report, it seems that Guo Cuihua has a history of taking analgesics, and it seems that it has been for a long time.

But this seems to be a little different from Guo Cuihua's situation!

"No, the previous forensic doctor told me that Guo Cuihua's blood sample was found to contain arsenic trioxide, which is highly toxic and will not be present in analgesics. ”

"If it's suicide?"

Ding Fan stood aside with a calm expression, supported the table with both hands, lowered his head and said in a deep voice.

"I have already asked Wang Deguang to find the source of this drug, there are not many places in several hospitals in the county that have this medicine, and even rarely prescribe this medicine to patients, unless it is used in a very small number of diseases that require it, and there will be strict records. ”

When Qin Lu heard this, he calmed down, and finally knew why Ding Fan was so calm about this matter.

It seems that he has been skeptical about this for a long time, but why hasn't he heard of it before?

"Guo Cuihua was diagnosed once in the hospital before, and the hospital found out that she had myeloma, and her family didn't even know about it at all, they always thought it was just an old rheumatism disease, and the only person who knew about it was the road, he only knew about it because he met it in the hospital, and it was he who told me about it, so I had the guess later. ”

Myeloma is a very painful disease for anyone.

Just imagine the feeling that the bones all over your body seem to be constantly gnawed by insects, and it is not strange for people with weak willpower to think of suicide.

Guo Cuihua can endure this kind of illness and persist for more than three years, which is rare.

But in the end, she probably didn't want to cause a burden to her family, so whether the murderer came to the door that day or not, she was ready to leave by herself.

Taking advantage of the nap time, Guo Cuihua increased the dosage of her medication, originally planning to take her own life, and she would not cause trouble to her children in the future.

Unexpectedly, the effect of the medicine only made her completely faint for a period of time, and she was stabbed to death.

"So, whether the murderer wants to kill her that day or not, she will die in the end!"

Qin Lu's expression was a little sluggish and she sat on the chair on the side, and muttered in a low voice, obviously this incident had a bit of a big impact on her, and she couldn't accept this result for a while.

Ding Fan walked up to her and reached out to pat her on the shoulder.

Guo Cuihua has actually thought about it, the two daughters have been settled, and the eldest daughter is about to get married, although it is a little late, the second daughter's life is also good, and she has nothing to worry about, rather than supporting it, being seen by the family, scattering all the family wealth to save her, and in the end, it is just in exchange for a year or two of life, in which the family is immersed in grief, this is not what she wants to see, so she plans to give up her life. ”

To be honest, Ding Fan didn't put much effort into the investigation of this point.

In his opinion, these are Guo Cuihua's personal behaviors, and they have nothing to do with this case as a whole.

It belongs to the kind of case that can be checked or not, and there is no need to pay too much attention to it, so it is to ask Wang Deguang to go to the hospital to inquire about the situation, and there is not much arrangement.

It's just that he didn't expect that when he took Qin Lu back to the guest house, Wang Deguang not only brought back news about the medicine from the hospital, but even saw the ring he had been looking for in the hospital.

No one expected that this ring, which had never been found, would finally be found in the hospital.
