The head of the household used to be engaged in engineering, but now the opening of a factory is actually the same as engineering, and the social relations are complex, and there are very likely to be disputes caused by economic disputes, labor disputes, and even industrial accidents. Pen, fun, pavilion www. biquge。 info

Han Bo nodded, and walked into the deceased's house with the top criminal investigators at the city and county levels.

Sure enough, it is very rich, the home decoration is very beautiful, not only beautiful but also very fashionable, it is definitely designed by a professional designer and decorated by a professional decoration company.

As soon as he entered the door, Han Bo sniffed first, looked back at the transparent windows in the north and south, and subconsciously asked, "Yang Ju, who opened the window?"

"Xiao Feng, what's going on with the window?" The technical police came in first during the investigation, and Yang Guosheng really didn't know about this situation.

"Report to the Yang Bureau, the scene remains the same, this is how the technical squadron came in, considering whether it is possible that the suspect poisoned the kitchen through the north window, I asked them when I came in, and I went around the back flower bed to see if there were any stampede marks, and whether there were any climbing marks in the back downpipe. ”

The kitchen has a range hood and a sliding door between it and the dining room, so you don't need to open the window for ventilation because of cooking.

The Wang detachment was also strange, staring at the window and muttering: "In the cold winter, why are the windows open?"

"Report to the three leaders, we also felt strange at first, and later found that the four deceased had all vomited, and the vomit in the old man's room had not had time to clean up. ”

This explanation is reasonable, and it can be seen that the case-handling police rely on the case-handling police to solve the case after all, and they have first-hand information, unlike leaders who need to listen to reports and need to read materials.

Han Bo didn't ask anything more, and found that the living room was very clean, and there was a shoe cabinet by the door, and there was a foot cover in the box on the shoe cabinet.

Take a brief look at the living room before moving into the kitchen.

The kitchen is the focus, the wok and rice cooker, and the microwave oven are opened one by one to see, smell the inside, check the condiments when they are finished, then open the refrigerator, even turn on the faucet to put water, turn on the gas stove and light the fire, and finally squat down to open the cabinet and carefully check the contents of the cabinet.

Detachment Wang and Deputy Director Yang were very embarrassed, they both wanted to investigate like Han Bo, and the key was that they were not very good at forensic technology.

"Yang Bureau, have the technical police taken samples of these ingredients, drinks and condiments?"

"I have taken it, I have explained to them, and there will be no omission. ”

Han Bo leaned on the window and looked outside, confirming that it was unlikely that someone had poisoned the kitchen from the window, turned around and walked out of the kitchen, and asked, "Comrade Feng Wei, could you please describe the scene that the deceased's uncle saw when he came in." ”

The detachment leader and the deputy director of the sub-bureau are all here, why do you ask me!

Feng Wei didn't dare to report beyond the level, and he was two levels overstep, so he hesitated for a while.

If you want to know the first-hand situation, of course, you have to ask the police who know the situation best, and the same is true when the Wang detachment went to the sub-bureau to guide the investigation of the case, I didn't think that Han Bo didn't give face, and frowned, "What about Han asking you, report!"

"Oh, yes!"

Feng Wei relieved himself and hurriedly said: "Report to Han, Fu Liqing, that is, the uncle of the deceased, when he came in, he found that Tan Xingtao said that he had a headache, the child's mother Liu Mei was lying on the toilet in the bathroom and vomiting, the old man was lying on the bed in the bedroom and vomiting, the child was already delirious, and hurriedly used this phone to call 120 for help." ”

"Fu Liqing opened the door?"

"Yes, Fu Liqing was also preparing to call 120 at that time. ”

Han Bo walked into the master bedroom, looked at the wedding photos on the wall and asked: "The child's mother's surname is Liu, and the child's uncle's surname is Fu, so Tan Xingtao is divorced, Liu Mei is the child's stepmother, and Fu Liqing's sister is Tan Xingtao's ex-wife?"

"According to the Han Department, Tan Xingtao is indeed married for the second time, and he divorced his ex-wife Fu Liqin a year ago. The comrades in charge of this line asked some insiders and found that the two had a lot of trouble before their divorce. Fu Liqing was not convinced, he felt that his sister was being bullied, and he had done something with Tan Xingtao, and 110 had gone to the police for this. ”

"The two of them don't have a good relationship?"

"It's not good, it's similar to the enemy, Fu Liqing leaked into the community last night. It is claimed that although Tan Xingtao is divorced from his sister, there are still disputes over the division of property, and we are verifying these circumstances. ”

"Han, we think this Fu Liqing is very suspicious, he didn't come early or late, but he came last night, and he couldn't explain it by coincidence. Yang Guosheng glanced at the Wang detachment and added in a low voice.

Doctors and forensic examiners suspect that it is cyanide-chemical-poisoning, which is as well-known as arsenic, and often appears in movies and television, but it is not so easy for ordinary people to get cyanide-chemical.

Without evidence, Han Bo would never have made up his mind.

walked into the child's room and looked at it, turned around and asked, "Yang Ju, has Fu Liqing's background investigation been, what education level does he have, what kind of work he does, and whether he has any chance of coming into contact with highly toxic chemicals?"

"It's being investigated, and judging from the current situation, he doesn't have a high level of education, and he has only graduated from primary school. Before his sister divorced Tan Xingtao, he had been following Tan Xingtao. Tan Xingtao began to let him do light work, and later when he became bigger, he made him a small foreman and took care of a few workers. ”

"Do you have a criminal record?"

"Nope. ”

"Did you claim revenge with others?"

Tan Xingtao likes the new and hates the old, abandoning his bad wife, how can he not be angry as a brother-in-law, and say a few angry words, it is normal, can he use a few angry words as evidence that he poisoned and killed people. The Han family felt that there was no need to ask this question, but they still asked it in order to clarify the facts of the case.

"This is really there, our police found that he threatened to make Tan Xingtao look good more than once. Yang Guosheng nodded.

The more suspicious Fu Liqing was, the more worried Han Bo became, for fear that they would have preconceived ideas.

Walked into the old man's room and picked up the trash can, held his breath to look at the vomit inside, asked Feng Wei, the criminal police officer of the sub-bureau, to go to the kitchen to get a pair of chopsticks, stretched it inside and checked it for two or three minutes, and suddenly stood up: "Wang Detachment, Yang Bureau, you two are seniors, experienced, I believe that people have been arranged to check what should be checked, and the next thing you can do is to wait for news." The leader of the hall rushed the ducks to the shelves and asked me to come over to guide the investigation, thinking that there is really nothing to guide, but I can't do nothing.

Just now, Comrade Feng Wei introduced that the four deceased had vomited, and if you look at this garbage can, you will know how much they vomited, and the technical police who came to investigate must have taken samples, and whether there are any poisons such as cyanide and chemical substances in it should be able to be tested quickly. If it does contain toxic substances, it means that the four deceased people ate or drank the same food or drink.

The problem now is that the four deceased vomited so badly that it is very likely that the medical staff took first aid measures such as gastric lavage after arriving at the hospital. In other words, the stomach may be empty, and it is estimated that it is difficult to extract the contents of the stomach from forensic pathological examination.

I suggest that the task force should check the eating habits of the four deceased, the children are picky eaters, some foods are difficult to digest, the elderly don't like to eat, and the fat is too high and greasy food lesbians don't like, combined with the rotten vegetable leaves in the kitchen trash can, the leftovers in the refrigerator, analyze and analyze what exactly contains toxic substances, and then trace the source of the poison. ”

As soon as the connoisseur speaks, he will know if there is one.

In the afternoon, he was busy checking Tan Xingtao's social relations and Fu Liqing's situation, which was really not taken into account.

Deputy Director Yang Guosheng was about to speak, and Han Bo continued: "On such a cold day, open the window for ventilation, if only one person is poisoned and one person vomits, the explanation is reasonable, it is very reasonable." Now the problem is that the family is poisoned at the same time, all vomiting, what should be the first thing they think about, I don't think they are uncomfortable like that, they will think about the air environment first, this is a doubt. ”

"Everyone is dead, the window has been carefully investigated, and Fu Liqing's fingerprints have not been found, how can this suspicion be solved?"

Han Bo turned around and pointed to the trash can where the old man had vomited, and said solemnly: "Detachment Wang, we have to consider the possibility that no toxic substances can be detected in the vomit. ”

"Han, you mean the murderer's poisoning method?"

"Judging from the symptoms described by several people, the deceased's family should have been severely poisoned, and it is more likely that they ingested toxic substances at home, and if no toxic components were detected in the vomit, then there were only two possibilities. The first is that the whole family has gone out together and got poisoned outside, so their activities before their death must be clarified, and the second is more terrifying. ”

Look at the scene, listen to the introduction, ask a few questions, and you can think of so much.

Yang Guosheng found that the young deputy director-level investigator was a bit level, and couldn't help asking: "Han Division, what else is possible?"

"Yang Ju, there are various forms of highly toxic substances, there are dissolved solids, powders, liquids, and there are also highly toxic gases! Poisonous gases can also kill people, and kill people invisibly, if the murderer is releasing poisonous gases, then the reason why the windows are open is easy to explain. Most of the poisonous gases have a pungent smell, and the deceased felt bad before they died, but they didn't expect it to be poisonous gas, so they opened the window to ventilate, but they had already sniffed in a lot, and it was too late to ventilate, and they didn't even know how they died. ”

Gas killing, this is not a trivial matter!

Detachment Wang and Deputy Director Yang were stunned, unable to believe that there was such a possibility.

It sounds really unbelievable, this possibility is really unlikely, but as a deputy department-level investigator sent by the provincial department to guide the investigation, Han Bo believes that all possibilities should be taken into account.

He opened the security door and pointed to the opposite side: "I suggest arranging a few more comrades to ask the residents of the community, especially the residents of this building, if they smelled a bad smell last night." When I came, I paid attention to the surroundings, but I didn't find a chemical plant, and there were obvious traffic restriction signs on the road at the entrance of the community, and large vehicles were not allowed to enter, let alone vehicles transporting hazardous chemicals.

And the weather is so cold, it is normal to open the windows for ventilation during the day and dry the quilt, but it is not normal to open the windows at night. What's more, this is a community, with thousands of residents living in the community, which can basically rule out the possibility of the leakage of highly toxic chemicals. Therefore, if there is no poison in the vomit, and if the deceased's family did not go out collectively yesterday, then it can almost be determined that it was a poison gas killing!"
