Bai Bingxi stroked her little face and said with a smile: "Promise sister, you will not live up to your father's expectations, you must be happy and happy, in the hearts of all of us, you are the strongest child." Good no good? ”

The tears on the little girl's face did not stop, but became more and more, and her big black eyes looked at Bai Bingxi.

Half-ringing, trembling and stretching out his arms, Bai Bingxi was stunned for a moment, then realized, and reached out to gently hug the little girl.

"Woo woo woo ......"

Bai Bingxi helped her to follow her back and said softly: "It's okay, cry, just cry." ”

After enduring it for so long, I must feel uncomfortable, and it will be better to cry.

The little girl's mother couldn't help but hide her face and sobs when she saw the girl's appearance.

Half an hour later, Bai Bingxi let go of the little girl, squatted down in front of the mess, picked up Gongzhang piece by piece, wiped the dust off it with his fingers, and put it in the woman's palm.

"Eldest sister, this is Comrade Zheng's honor and pride, these are lives for us, please keep them safe, and don't throw them away at will."

After a pause, he continued: "We, the people's policemen and soldiers, are your family, you can tell us any difficulties, we will solve them for you as soon as possible, please mourn." ”

Bai Bingxi hung the pennant on the wall and walked out of the bedroom.

Bai Bingxi sat down on the sofa in the living room and saw Forensic Doctor Yang retreat from the bedroom.

Bai Bingxi got straight to the point, "Forensic Doctor Yang, what's going on?" ”

Forensic Doctor Yang took out his mobile phone, swiped it twice, and handed it to Bai Bingxi, "Major, this is the last message sent by Captain Zheng before he died, we saw it from his wife's mobile phone, you see, there are only two letters on it - 'ZX', look, do you have an idea?" ”

"Don't you know what his wife means?"

Forensic Doctor Yang shook his head, "She said she didn't know, besides, she is now stimulated and emotionally unstable, so we don't want to ask too much." ”

Bai Bingxi muttered: "Since there are only two letters, and it is the last piece of information, will it be related to the cause of his death?" ”

Forensic Doctor Yang cupped his eyes, squinted and said, "Very likely." What could it be? Initials of the murderer? Clues to where the evidence is placed? ”

Bai Bingxi shook his head, "Not really, the murderer didn't even let go of his bones, and he wouldn't let such evidence show us and guess it so easily." ”

Forensic Doctor Yang thought for a while, and said half-guessingly, "You mean that this must be related to the cause of Captain Zheng's death, but this is here to confuse us?" ”

"Well, the murderer is meticulous and has been working until today, we don't have the slightest information about him, and we deal with him and are always in a passive position. Now it's not what we can find, it's what kind of evidence the other side is willing to show us, and which direction they want to lead us. ”

Forensic Doctor Yang sighed, "That's not easy, really let Captain Zheng's death be unknown, and he can't even find the murderer who killed him?" ”

"Forensic Doctor Yang, there is no impermeable wall in the world, the murderer cannot have no mistakes at all, all the logic is opposed to each other, in the same way, he has an imaginary side, and there is an unexpected side, the evidence he gives us must be the evidence he wants us to know, we are the opposite, think from the opposite side, and see what evidence he least wants us to know."

Forensic Doctor Yang suddenly realized, "You mean that looking at the evidence provided by the murderer is trying to avoid which place, which place is the place where we are trying to find evidence, am I right to understand this?" ”

"That's right!"

After a pause, he continued: "Forensic Doctor Yang, when you talked to me on the phone, you said that this incident was related to the previous terrorist incident?" ”

Forensic Doctor Yang raised his head violently, "Oh! Right! Major, we checked the person who met with Captain Zheng on the day of the incident and found a very suspicious person. ”

Forensic Doctor Yang took out the documents in his work bag and showed them to Bai Bingxi, "Look, it's this person, he and Captain Zheng don't know each other, that day was the first time they met, and after talking for about fifteen minutes, the two left separately." ”

"Did you get into an argument?"

"No, however, from the point of view of monitoring, this person has a lot of body movements, especially hand movements, from a psychological point of view, in this case, he may be very emotional, but he did not push such radical behavior."

Emotional but not attacking the other party, there are two possibilities.

First, his emotions towards Captain Zheng did not reach the point where he needed to solve it.

Second, he is rational enough to control his behavior well, after all, it is illegal to attack the police, and he is not clear about the skills of the police, so he will not attack rashly.

"What is the identity of this person?"

Yang forensic doctor said, "This is a coincidence, this person is called Zhao Xu......"

Bai Bingxi hurriedly interrupted, "Wait! His name is Zhao Xu? ”

Forensic Doctor Yang nodded thoughtfully: "Yes!" Zhao Xu, ZX. ”

"It's suspicious."

"Yes, if it weren't for the Major's point just now, I would have thought it was a very reliable piece of evidence, and I would have followed this clue all the way up, because there was a more coincidental ......."

And then he said, "It's... What I told you about the terrorist incident, this Zhao Xu is a biological brother with one of the men in that group of terrorists. ”

Bai Bingxi raised his eyebrows, "Oh? ”

"After DNA verification, the identity of the terrorist can already be determined, this person's name is Zhao Wang, he committed an accident five years ago, went to prison, was released from prison this year, and has not returned home since he was released from prison, wandering outside, and then his younger brother Zhao Xu has come to look for him, and the two brothers have met, and the relationship is quite good."

Bai Bingxi suddenly said loudly, "I remember... On the night of the terrorist incident, Captain Zheng was also on the scene and was in charge of negotiating with the terrorists. ”

"That's right!"

Bai Bingxi said, "According to the available evidence, what the murderer wants to show us is that Zhao Xu mistakenly thought that Captain Zheng killed his brother Zhao Wang, and secretly killed Captain Zheng out of hatred to avenge his brother." ”

Forensic Doctor Yang nodded, "That's logical. ”

"What time did Captain Zheng and Zhao Xu meet?"

"Eleven o'clock in the morning."

"And where we met?"

"Near the sewer we found last night."

Bai Bingxi thought for a while, held his chin and said, "If I'm not mistaken, the place where Captain Zheng was on duty that day was the western suburbs, and when he came back from the western suburbs, he said that he had something to report, so there is a suspicion here, since Captain Zheng did not report back to the police station immediately after meeting Zhao Xu, but only reported that there was something important to report after going to the western suburbs on duty, indicating that the matter to be reported had nothing to do with Zhao Xu at all, but was mostly related to the affairs of the western suburbs, and on the way back, he was killed, according to the direction that the murderer pointed out to us, He wanted us to think that Zhao Xu killed Captain Zheng, thinking about it this way, why didn't Zhao Xu kill Captain Zheng in the western suburbs, but instead killed him in the place where he had met Captain Zheng before, isn't it easier to get it in the remote western suburbs than in the crowded urban areas? And ......"
