"Team Yan, these are the materials that the comrades have sorted out overtime, and there is information about the 'Yunxiang Murderer Imitation'." A uniformed policeman walked into Yan Feng's office and handed over a stack of materials, "According to the instructions of the Yan team, we first focused on investigating the movements of the three suspects in the last few days, and then divided a team to visit door to door, including the physical evidence left at the scene, and tested it again." ”

"So far, has there been no similar case committed by the 'Yunxiang Murderer Imitation'?" Yan Feng frowned, and then asked, "Those three suspects, is there any difference between their testimony before and after?" ”

"There are different differences, but most of these differences are supplements to my whereabouts that day," Liu Wenyu said, "but after repeated re-examination, we still found a little breakthrough." ”

After receiving the information, Liu Wenyu flipped back a few pages, and then said: "We found this under the armpit of the victim's discarded clothes. ”

"This is ......" Yan Feng squinted slightly, looking at the inconspicuous spot in the picture, "What is this?" ”

"A little trace of vomit." Liu Wenyu continued to flip back a few pages, and then found a photo, "And this, this wipe mark, after the laboratory test of the trace examination department, it was confirmed that it was human excrement." ”

"How did the excrement get on this part?" Yan Fengzai carefully examined the trace on the shoulder of the clothes and asked, "If it was deliberate, then why did the suspect do this?" If so, why? ”

"This ...... It is not known yet, and the source of excrement and vomit is being searched from house to house. Liu Wenyu explained, "Among these excrements, a small number of intestinal parietal cells were found, and according to these intestinal parietal cells, we have found some of the DNA information contained in them, and now we are looking for the owner of the excrement based on these DNA information." ”

"Well, that's good," Yan Feng pondered for a moment, then said, "But there's no need to be so troublesome, let's test the DNA of those three suspects first, and then investigate the area covered by the two crime sites from house to house." ”

"It's because DNA isn't theirs, so there hasn't been much progress until now," Liu Wenyu sighed, "It's been almost half a month, but there is still no breakthrough progress, it's really unwilling......"

"There is nothing to be reluctant about, if the trace examination department can find these physical evidence in the first pass, the progress will be much faster than now." Yan Feng frowned, and his tone revealed a bit of reproach, "By the way, there is no progress on the pursuit of Jiang Hongying and Jiang Xiaoyu?" ”

"I'm sorry, Team Yan......" Liu Wenyu felt a hot pain on his face, "Yunxiang Murderer Imitation Criminal" and Jiang Xiaoyu, one of the two disappeared without a trace after committing a heinous crime, and the other not only committed murder at the door of the police station, but even escaped after the police laid a strict surveillance net, all of which seemed to have slapped the police in the face twice, but now the police have not made the slightest progress in the arrest of the two.

"If you know the shame, then cheer up and cheer up." Yan Feng glanced at him, "So ......"

"Yan Feng, I think you should take a look at this!" A rush of footsteps interrupted the conversation between the two, only to see that Xiang Haisheng looked a little embarrassed at the moment, his hair was stuck to his face from the heavy rain, and his suit was already wet, he walked in breathlessly, put a box of tape recorders on Yan Feng's table, and then sat on the chair.

"Yo~ Professor Xiang, what's going on, it's so embarrassing?" Immediately afterwards, Xu Wenxin's sneering voice came from the door of the office, "Team Yan, good afternoon~"

"Xiao Xu, what's going on?" Yan Feng frowned and looked at the two who had just come in, "And you, why are you so embarrassed?" ”

"That's a long story~ Team Yan," Xu Wenxin glanced at Xiang Haisheng who was panting, and there was mockery in his eyes that couldn't be concealed, "This guy, I don't know what kind of illness he is committing, it's still raining heavily outside, and he ran all the way back without practicing umbrellas, and as soon as he entered the door, he said that someone was going to kill him, and then ran here like crazy, startling those comrades on duty!" If I hadn't recognized him, he might have been detained by now because of trespassing on the police station. ”

Xu Wenxin's yin and yang weird voice came, but it made Xiang Haisheng, who was already excited, angry enough, he glared at her fiercely, then looked at Yan Feng, and said, "Team Yan, look!" This is the evidence that proves that Wen Yifan is the serial murderer! ”

"You fart!"

"Shut up!" Yan Feng rubbed his temples, picked up the thermos pot, poured a cup of hot water for Xiang Haisheng, and then said, "What's the noise?" This is the office, it's a place to handle cases, not for you to quarrel! ”

Sticking out her tongue, Xu Wenxin stepped aside, and in the process, she didn't forget to glance at Xiang Haisheng, it was obvious that Xiang Haisheng's accusation against Wen Yifan made her very unhappy.

"Officer Yan, listen to what I recorded, there is definitely definite evidence in it that can confirm that Wen Yifan is the serial murderer!" After drinking a sip of hot water, Xiang Haisheng let out a long breath, Fang Cai's hanging heart finally let go, looking at his embarrassed self, his eyes couldn't help flashing a trace of anger.

That damn Wen Yifan!

In fact, this time to meet him, although he did not know the bottom of his heart, but he still made more comprehensive preparations, and even set up an email, if he did not cancel this scheduled email the next day, this email will be sent to Harvard University, the FBI and China's Public Security University respectively, which will record all the facts of the case in detail, and report what he thinks is a major suspect - Wen Yifan.

At that time, he believed that no matter how good the other party was at concealing it, under the investigation of these three parties, it would inevitably be exposed.

But when he really faced the "head wolf", he realized that all the original preparations were useless at that moment, and those seemingly comprehensive preparations and psychological hints about himself seemed so pale in the face of the almost overwhelming threat of death.

In fact, Wen Yifan can't be blamed for everything, in addition to Wen Yifan's absolutely accurate control of his heart, more factors come from his experience.

As a professor, as a psychological profiler, there are very few moments of face-to-face confrontation with those criminals, more just according to the layout of the scene and all the clues, pretending to become a "criminal" and reading the heart of the criminal, this is the job of a psychological profiler.

may be due to the smooth sailing of the road that made him arrogant, it may be that the death threat from the criminal has not befallen him, these factors caused him to subconsciously regard Wen Yifan as an ordinary criminal who sighed behind the iron railing after being caught, but unfortunately, Wen Yifan is not.

This is the reason why Wen Yifan has never regarded him as his opponent, and during this period of time, a large part of the reason why Wen Yifan dared to appear so presumptuously at various crime scenes was also because Xiang Haisheng was really not worth his too much caution - just like now, it was clear that Xiang Haisheng was the closest person to the truth, but with only a slight threat, his forcibly established psychological line would collapse instantly.

In other words, if Yan Feng had so much evidence today, and he came to visit him alone, it would be the most troublesome situation for Wen Yifan, and it would even lead to the exposure of his identity again, which would cause him to have to transfer again.

Gritting his teeth, Xiang Haisheng's fear had already turned into anger and hatred at this moment, these emotions combined with the soaked clothes made him tremble, and there was only one factor that could make him take some comfort from this shame, and that was-

I'm still alive!

The slight sinking of his shoulders was not a means for him to test Wen Yifan, but a real sigh of relief. Even at that time, after he inadvertently made this micro-expression, his heart was still full of regret - it was the chagrin that he was afraid that the emotions expressed by his micro-expression would be captured by Wen Yifan.

Obviously, Wen Yifan did capture this emotion at that time, but it was obvious that he was thinking too much - this action was really just Xiang Haisheng's inner thoughts, not a temptation, but Wen Yifan obviously overestimated the latter, so he had a conjecture about the "mille-layer game".

At that time, when Xiang Haisheng, whose heart was about to mention his throat, was still annoyed on the first layer, Wen Yifan's high-speed thinking had already entered the fifth or even sixth layer, so that when Wen Yifan said the word "temptation", his brain was still stunned for a moment, and then he reacted.

Although it was because it was overrated, at least it survived.

Xiang Haisheng swallowed his saliva, and then said: "Officer Yan, you must listen carefully to the content of the tape recorder, you must listen carefully, when you listen to it, you will be able to understand that everything I said is the truth!" ”

"It's ridiculous, you want to prove that Mr. Wen is a serial murderer who killed so many people through a recording," Xu Wenxin sneered, "Could it be that Mr. Wen also admitted to you that everything was not successful?" ”

"Whether you admit it or not, you can hear it by just looking for a few experienced criminal investigators!" Xiang Haisheng almost roared and shouted, "Why don't you believe me?!" ”

"Professor Xiang, you better take a good rest, don't catch a cold," Yan Feng got up and comforted, "I will listen to this tape carefully, if I can really confirm that Wen Yifan is the murderer of the heartbreak, I will definitely not spare it." ”

"Of course, if there is no way to prove that he is the murderer, I will personally come to the door to apologize." His eyes swept over Xiang Haisheng and Xu Wenxin, and he looked back at Liu Wenyu on the side, "Send it to the Professor's Hotel!" ”

"Yes!"
