Colleague C said this, his mood was a little low, not as happy as he said, he took a puff of cigarette again, and said: "But when I think of Cheng Sen taking his life into it because of this incident, I feel very bad in my heart, a very good honest person, just gone." ”

Liu Yefang nodded, and asked again: "Who can prove that you donated one million to the company?" ”

Colleague C replied: "The current management of the company basically knows about it, and they have laughed at me a lot because of this. ”

"Okay, we'll go to collect evidence later, if it's true, it's nothing to do with you." Speaking of this, Liu Yefang changed her words and asked abruptly: "Where were you the night before yesterday?" ”

Colleague C was stunned for a moment, and then said strangely: "I'm at home, my insider went on a business trip a while ago, and I stayed at home with the children." ”

"In this case, then we will go first, you can get busy." Liu Yefang simply took me out of the repair workshop.

When we found the office building, we grabbed a balding middle-aged man and asked about the company's donations in the previous year, and what he said was basically the same as what my colleague C said. A year ago, colleague C did donate 1 million and got more than 70 shares of the company, but within two days, the chairman ran away with the money, and then the person who took over directly stated that the previous equity distribution was invalid and redistributed, this time colleague C only got a very small part.

When I walked out of the company's gate, I couldn't help but ask, "Senior sister, colleague C should be able to rule out suspicion, right?" Seeing that he is still a very responsible old employee and has a deep affection for the bus company, such a person should not be able to commit murder, right? ”

Liu Yefang thought for a while and said: "It can't be completely ruled out, although he borrowed money to buy shares in the company, but after the former director fled with the money, he did not have the ability to repay this debt, and it is still possible to carry out the murder plan, so so far, he is still a suspect." ”

Because the bus company has no clues to investigate, so we had to return to the team, there was no one in the team at this time, Zhang Bin went to the traffic police team to check the bus, Sun Jianguo also took someone to the outside to investigate the arrears on the account book, only Ma Zhiyuan was in the team, but after inquiring, he went to the morgue early in the morning.

Just ten minutes after sitting down, Ma Zhiyuan suddenly knocked on the door and came in, saw me and Liu Yefang, and immediately walked up and said, "It just so happened that you guys came back, and I found a new situation." ”

I asked, confused, "What's the matter?" I heard you're going to examine the corpse again? ”

"yes, if you hadn't said last night that all three of them might be acting, I wouldn't have thought about it." Ma Zhiyuan said and took out a piece of paper and said: "I examined all three corpses this morning and found that although they were all drowned, there was one characteristic that was different. ”

"What do you mean? Does drowning make any difference? "The more I listened, the more confused I became, since they were all drowning, what was the difference?

"Of course, there is a difference, drowning depends on what liquid you drown, such as clear household water, sea salt water, river water mixed with sediment, lake water with green algae, filthy sewer water, and many other situations."

I still don't know why, what's the difference between these drownings, so I asked, "And then?" Aren't they all drowning? ”

Liu Yefang suddenly interjected: "Is it true that after drowning, different characteristics can be found in the deceased?" ”

"Yes, there is finally a sensible victim, the victims who drowned in different liquids, the residues in their respiratory tracts are different, even if they are placed in the same liquid after death, the residues in the respiratory tract will not change."

"I found a small amount of algae and sediment residues in the respiratory tract of the driver Cheng Sen, but no similar residue was found in the respiratory tract of passengers Yang Ziqiang and Cha Taikang. I suspect that the huge volume of the bus must have stirred up the sediment at the bottom of the reservoir during the accident, so it can explain the algae and sediment residue in Cheng Sen's respiratory tract. ”

"But Yang Ziqiang and Cha Taikang did not have it in their respiratory tracts, which shows that the two of them did not drown in the Mi Nan Reservoir at all, but had already drowned in other liquids, and finally threw their bodies into the Mi Nan Reservoir."

When I heard this, I suddenly felt that I had drowned in different liquids, and the corpse had different characteristics. However, Ma Zhiyuan came to the conclusion that Yang Ziqiang and Cha Dakang did not drown in the reservoir, so the two people who may have gotten into the car are not themselves, but are just wearing the same clothes. But when Yang Ziqiang's four subordinates came down to identify the surveillance video last night, they unanimously determined that the two people were Yang Ziqiang and Zha Taikang, what is going on?

If it wasn't me who got on the bus, how did the body get to the Minan Reservoir after that? Again, this is an unavoidable problem.

Thinking of this, I was uncertain and said, "The four were lying last night?" ”

Liu Yefang thought about it carefully for a while before saying: "I don't know, but unless Yang Ziqiang and Cha Taikang were killed by the four of them, there is no need to lie to us, and there is a possibility that people who are very familiar with them can use their body movements to confuse the glasses of the other four." I prefer the second type, because in a homicide case, there is a potential clue, that is, there are up to three murderers, usually one person who commits the crime alone, rarely two people commit the crime, and three is even less. ”

"The murderer in the homicide case, if he is caught, is at least indefinite, basically the death penalty, no one wants to put their life in the hands of others, even if they trust people again, not to mention a group of friends who only have interests in their eyes, so the probability of them committing crimes is extremely low."

The three of us discussed, and decided to interrogate the four people separately, even if the possibility of them committing the crime is extremely low, they can't let it go, when the first person was arraigned, Liu Yefang asked him some detailed questions, such as which way to go home, which hand opened the key to the house, what did he do, drank a few glasses of water, went to the toilet several times, and asked the same question dozens of times, the answer was still the same, not to mention that the person being interrogated felt annoyed, even I felt bored.

Liu Yefang said at this time: "Replace the next person." ”

At this time, if the person who was arraigned was amnesty, he quickly ran out, and his eyes changed when he saw Liu Yefang before going out, and the situation was the same when the second person came in, after being questioned dozens of times, he was busy walking out of the interrogation room under the care of the police when he heard the news of the replacement.

Although I couldn't understand it, there must be a reason for the senior sister to do this, so I continued to let the third person in.
