The sky was getting dark, and the members of the task force were still busy going in and out of Villa No. 13, attracting many people who came out for a walk to stop and watch.

"Everyone, pay attention, evacuate the onlookers immediately! The murderer is very familiar with this place, and is likely to be watching from the side!"

Deputy Captain Ma frowned and said to everyone: "Don't be so excited, calm down, quickly count all the traces extracted, and send them back to the bureau!"

"Understood!"

Xiao Ran stood on the balcony on the second floor of the villa, watching several colleagues persuade the onlookers to leave, and looked around, but found no suspicious person.

Turning around and going downstairs, looking at the remains in the living room on the first floor, which were about to be put into a body bag by the forensic doctor, he couldn't help but ask: "This, it must have been many years, right?"

The head of the forensic department of the Second Bureau, Mao, is an old forensic doctor with decades of experience, he looked up at Xiao Ran in front of him, and said with a smile: "Judging from the degree of corruption of clothes, it must be at least 5 or 6 years. ”

Xiao Ran nodded and didn't ask any more, after all, he just came to assist Chai Shaoying's case - as for this kind of case that is too old, let's let the second bureau be busy, anyway, it should have nothing to do with the former owner of this villa.

"Speaking of which, you've helped us a lot. ”

Section Chief Mao watched his forensic doctor pull up the body bag, stood up and took off the plastic gloves, and gave Xiao Ran a thumbs up: "When the case entered a stalemate some time ago, our forensic department stared at Chai Shaoying's corpse all day long, thinking that we could read some useful information from the corpse - fortunately, Deputy Brigade Ma transferred you over, otherwise this case would have to be dragged back." Well done lad, amazing!"

Xiao Ran raised the corners of his mouth and shook his head humbly: "I just found it by chance, and I still need to continue learning." ”

At the end of the finishing work, the technical team installed a night vision probe on the small dirt slope, and turned on all the cameras in the four corners of Villa 13 and connected them to the private monitoring network.

If the suspect detects their police movements and comes to verify, as long as he dares to approach, he will be caught by the surveillance.

After returning to the second bureau, the technical team and the forensic department worked overtime, but Xiao Ran was ready to get off work.

After all, he had nothing to do if he stayed in the brigade, and he had to wait for all the traces to be examined before he could determine his next move.

Moreover, now that the facts of the case have become clear, the footprints, fingerprints, and DNA are all there, and it has been preliminarily determined that the suspect is particularly familiar with the Blue Island villa area - knowing that if no one can be found yet, it would be too underestimated.

The next day was Friday, and it was overcast.

Xiao Ran came to the second bureau, and suddenly found that the forensic department and the technical team who had been busy all night were also gloomy.

Looking at Gao Qiang, who had a tired face, Xiao Ran frowned slightly: "What's the matter?"

Gao Qiang took a deep breath, shook his head and said, "Fingerprints and DNA have not been found in the search library...... However, a residue of substances belonging to Chai Shaoying was found on the outside of the sleeve, and now it can be basically determined that this person is the murderer. ”

"So this man has never had a criminal record, so he's either a first-time offender, or he's a veteran but hasn't been discovered. ”

Xiao Ran rubbed the bridge of his nose and said, "Although I haven't checked it out for the time being, there are still rules to follow, and now it's just the last layer of window paper, he has left so many flaws, he can always find him." ”

Gao Qiang nodded: "You're right......"

It didn't take long for all the members of the task force to arrive.

Immediately, Deputy Captain Ma immediately convened a meeting of the special case group, and Zhang Zhenhua, the head of the Criminal Police Brigade of the Second Bureau, who had just returned from other places, also hurriedly came to the venue.

"Is that Xiao Ran?" Zhang Zhenhua asked impatiently as soon as he arrived at the venue.

Xiao Ran stood up from the corner: "Report to Captain Zhang, I am." ”

Zhang Zhenhua strode across the conference room, looked at Xiao Ran carefully, and finally patted Xiao Ran's shoulder hard, and sighed in a low voice: "Lao Lei picked up a baby......"

After speaking, without waiting for Xiao Ran to answer, Zhang Zhenhua turned around and walked to his seat, and said decisively: "Now that the meeting is held, how are the results of the trace identification?"

Listening to Gao Qiang's reply, Xiao Ran sat back and saw that this Captain Zhang was a resolute person.

"There is no such person in the search library?" After listening to Gao Qiang's answer, Zhang Zhenhua looked at Ma Kai beside him: "Old Ma, tell me." ”

"Since the fingerprints and DNA can't be compared, the net can only be laid from the two aspects of the suspect's physique and the familiarity with the Blue Island villa area. Ma Kai said.

"By the way, Xiao Ran also found a strand of blue wire on the steel bar at the entrance and exit of the villa's bathroom yesterday. Gao Qiang suddenly thought about it and said quickly.

"Wire?"

"Yes, the colour and material are similar to our summer short sleeves. Xiao Ran nodded and said.

"Security uniforms?" Ma Kai said immediately, after all, excluding the clothes worn by individuals, the clothes that are most similar to the short-sleeved police uniforms are the clothes worn by the security team.

Hu Han agreed, saying: "It is very likely that the property security guards often patrol the community, and in terms of familiarity, there is a high probability that they will know the situation under Villa 13." ”

"Since there is such a possibility, let's check it!" Zhang Zhenhua said decisively.

After the case discussion meeting, the special case team immediately joined forces with the police stations and public security police around the Blue Island villa area to visit the security teams and property personnel around the villa area.

The focus is on male personnel who are about 1.68 meters tall and have a thin body.

Time passed minute by minute, and at noon, the members of the task force responsible for investigating the Blue Island villa area suddenly came with news.

They learned from the security captain of the villa area that a week after Chai Shaoying was killed, a security guard named 'Miao Yu' suddenly left his job.

According to the security captain's description, this person named 'Miao Yu' is very similar to the presumed suspect's physical characteristics.

Upon learning of this information, the task force quickly collected information on this person: "Miao Yu, male, born in a certain year, is 28 years old, 1.67 meters tall, and has a thin ......."

And according to the latest information, this person seems to have been in contact with a black gang for a while a few years ago, but his behavior is very stable and there is nothing out of the ordinary. ”

Hu Han pointed to the figure on the projector screen and said: "After this gang was uprooted by us, Miao Yu no longer had any suspicious behaviors—we don't know exactly what this person's attitude is at work." ”

Xiao Ran looked at the photo of 'Miao Yu' on the curtain: thin lips, convex cheekbones, two slender eyebrows are very close, but the triangular eyes under the eyebrows are very wide.

At first glance, most people can't help but have a feeling that this person is not easy to get along with.

The most important thing is that the first moment he saw this person's face, Xiao Ran's eyes jumped violently.

"Anyway, since there is a suspicion, let's find him first and have his fingerprints checked. I'd rather check the mistake than miss any suspicious people, etc.!"

Zhang Zhenhua's words were sonorous and powerful, and he turned his head to look at Hu Han: "Do you know where his family lives?"

"I know, his family lives on the 4th floor of Unit 2, Building 6, Philharmonic Community. Hu Han then said.

Hearing this, Xiao Ran raised his eyebrows - Isn't the Philharmonic Community where Chai Shaoying's mother lives?

And one is in Unit 1 of Building 2 and the other is in Unit 2 of Building 6, and the distance between the two is not very far.
