To solve the case, of course, we have to use evidence to speak, Wang Dong has already targeted the suspects on the bodies of the three women, and began to speculate in his heart, is it her? Or is she? Or maybe the two of them are in a gang, but what is the motive for committing the crime?

Lu Xiaotian is the head of the family, it can be said that without Lu Xiaotian, there would be no Lu family, and if Lu Xiaotian was killed simply, it could only be the loss of the Lu family.

From the point of view of inheritance, the three of them should be able to get a share, from the perspective of motivation, only there is something wrong between Lu Chang and Lu Xiaotian, Wang Dong's eyes have always suspected that Lu Chang did it, but Xia Zhiqing put forward a different opinion.

She thinks that Luo Meijuan is also suspicious.

First of all, don't look at Luo Meijuan's repeated claims that she wants to solve the case as soon as possible, but the objects of her suspicion are only Lu Mu and Lu Chang.

However, don't forget that when she was at the Lu family, when Luo Meijuan got up to pour water for Wang Dong, she didn't mean anything strange, but she didn't expect that the kettle was already broken, but it was only broken on the day Lu Xiaotian died.

What does this mean? It must indicate that Luo Meijuan is panicked, she has been back to Lu's house in this royal year, and she has also come back recently, otherwise it would be impossible to be so clear about the situation at home.

On the one hand, it is the deadline to solve the case, and on the other hand, the two suspects can't be caught in any way, Wang Dong thinks that he can simply send the two of them to the team for interrogation separately, and check them out according to the trajectory of each day's life, I don't believe it, they can always be unrevealed.

"Why don't you check the source of the poison and see if anyone has bought arsenic recently?" Xia Zhiqing felt that Wang Dong's method was not very good, if the two of them insisted that it had nothing to do with them, it would not play any role at all except to make the police more embarrassed.

Usually, no one will have arsenic at home, unless it is for a special purpose. It is undeniable that arsenic does have many uses, but none of them can be used by ordinary people under conventional circumstances.

Arsenic is an excellent traditional Chinese medicine, which can be used to kill insects and detoxify sores, but its dosage and usage are by no means good for ordinary people to master, and no one has the courage to test with arsenic.

So the source of arsenic may also be a big hole.

Under the premise that there is no way to bring two people back to the team for a detailed investigation, it is also a good idea to check the source of the drug first.

Arsenic is not a commonly used drug, and many pharmacies do not sell this kind of thing, but any store that can sell arsenic, first, must have a doctor's prescription, second, must have the ID card of the person who bought the medicine, and third, basically the person who bought the medicine has been monitored and completely photographed on the face.

The perfect urban monitoring system has basically covered every corner of the city, but if you want to put all these information together, you must not only have time, but also have huge manpower and material resources, and Wang Dong and Xia Zhiqing lack these two points.

Although it is only a district of the city, there are no less than dozens of pharmacies of all sizes, plus clinics with medical qualifications, just running all over these places, it has been running for a whole afternoon, and the video brought back is too late to watch, it seems that tonight can only be another sleepless night.

The dinner of two people is less romantic, but more warm, tired of the body of the day, only at this time can I feel a trace of relaxation, after eating, I will devote myself to busy work.

I don't know if I don't check, I was really shocked when I found out, it turns out that arsenic will have so many sales every day, although the weight of each time is only a little bit, but if you add it all up, this amount is enough to make people feel shocked.

The image in the video should be compared with the information left on the ID card, gradually, with the arrival of late night, the list in the hands of the two people gradually shrunk, until it was confirmed that the last person was not familiar with the figure, the two people finally couldn't help but yawn, and looked at the watch, it was not much worse than midnight.

"Let's go to sleep first, and we'll talk about it tomorrow." After the hard work of this day, there was no emotion for even any romance, Wang Dong hurriedly said to Xia Zhiqing, and then returned to his room, his face was too lazy to wash, he took off his coat directly and got into the bed.

I slept groggily this night, probably because I thought about too many things during the day, and even dreaming when I was sleeping I couldn't do without the case, I don't know when, Wang Dong suddenly woke up from the dream, looked at the ceiling above his head, and it took a long time to react where this was.

Damn, I'm having nightmares again.

Got up and poured a glass of water, swallowed it slowly, the mood was better, Wang Dong looked at his watch, it was only half past six, the sky outside was still a little dark, his sleepiness was much less, since he couldn't sleep, he still got up, he just showed his romance yesterday, so show his hospitality today.

After getting dressed, Wang Dong quietly walked out, the early morning of the city has gradually begun to be lively, the roadside stalls have already opened, the chimney is steaming, and several old people in thick down jackets are lining up and chatting.

Wang Dong was at the end of the line, and there was a small talk between the old people in his ears, and after listening carefully to a few words, his heart was happy, and these people were actually discussing what mistakes the president of the American empire had made.

There are so many things about firewood, rice, oil and salt around him that are not discussed, and the things that can't be beaten by eight poles are so hot that they are talked about in full swing, looking at the spit stars flying in the mouths of several old people, Wang Dong had to sigh, pretending not to hear, and honestly waiting for his turn.

Fortunately, the speed of this shop is quite fast, after a while, another pot of fritters out of the pot, several old people in front of the row have dispersed, Wang Dong finally ranked first, the middle-aged people in the shop probably saw Wang Dong's helpless expression just now, while turning over the fritters in the pot, while saying to Wang Dong: "These old people are wide enough, you just listen for a while, my ears are tortured every day, this is good, you don't need to watch the news, you can hear clearly what is happening in this world." ”

Wang Dong heard Zhile, it seems that he is not the only one who is tortured, compared to this old man, he is not bad, took the soy milk fritters handed over, waved his hand to the boss, and Wang Dong walked home.

At this time, Xia Zhiqing should also get up.
