"Huh?"

Hearing this, everyone twisted their necks to look at Ye Fan, and for a while, they could hear the sound of clicking bones twisting, and several police officers turned too fast and almost didn't twist their heads.

"You mean, it's just a skit still from the gala?"

"Or is it a show from your forensic medical school?"

"Victim or your roommate?"

......

He Pingfei and the others had an expression of are you joking, if they didn't understand that Ye Fan was not the kind of person who couldn't figure it out, they would definitely think that she was playing with them.

Team Chang looked at these two photos and understood what Ye Fan meant, he said with a calm eyebrow: "Do you want to say that the murderer who killed Li Lanke was a murderer who simulated and copied the sketch at the Christmas party?

Ye Fan didn't nod or shake his head, just said his opinion: "The Christmas party is an internal event of A University, except that the invited guests are teachers and students of this school, and the on-site shooting and video are all students of this school. ”

The Christmas party is specially recorded as a video of the whole party, as a gift to the guests, I heard that the student union has done a warm and touching job, but it has not been sent out yet.

So if the murderer really copied the murderous scene of the sketch at the party, 80% of them were the people who were present that night, and the remaining 20% were accidents, and there are always countless unexpected things happening in this world.

But in any case, the murder sketch at the A big Christmas party was the breakthrough of their next investigation.

The three days after the murder is the golden period for solving the case, but due to the murderer's caution, the police now have too few clues in their hands, in this case, they can generally only find a needle in a haystack, start from the victim's social relations, investigate the people who have had a holiday with her, and investigate them one by one.

Although the news provided by Ye Fan shocked them, and they felt a sense of hair in their hearts, it also gave them the direction of the investigation.

The Chang team pondered for a while and said: "He Pingfei, you immediately take someone to A University to investigate, you must get the detailed information of all the guests and teachers and students who participated in the party that night, the most important thing is the video of the party, and the participating sketches, including the main creators of the sketches, must all be investigated." ”

The murder sketch from the main creator to the participating students are all first-year forensic science students, Yun Xueshuang and Zhu Shengyang are the starring actors of the sketch and also participate in the creation of the sketch.

Ye Fan, as one of the hosts of the party night, and Yun Xueshuang and Zhu Shengyang's roommates, for the investigation of this line, she provided direction, and then avoided suspicion and did not participate in the discussion, people's hearts will always be biased, even if she is confident that she can maintain her heart without being affected, but her subjective consciousness will still be affected to some extent.

Everyone has worked together for a few months, and Ye Fan's strictness in dealing with the case is also understandable.

After discussing it for a while, the Chang team thought of Lin Yanyan and Hong Yi, who Ye Fan mentioned and had an intersection with Li Lanke at the party, and said to He Pingfei: "Focus on investigating Lin Yanyan and Hong Yi to see what their relationship with Li Lanke is." ”

"Yes, Team Chang. He Pingfei said.

The line of the A big party should be investigated, and Li Lanke's interpersonal relationship should also be investigated carefully.

Team Chang: "Han Han, you are responsible for investigating Li Lanke's interpersonal relationships, especially those who have had holidays with her, and her secret boyfriend, you must dig people out." ”

"Understood. Han Han made an ok gesture.

"Ashi. The Chang team called the name of a criminal investigation police officer again, and said: "You take someone to visit the xx community, check whether any suspicious people have been found in the xx community recently, by the way, and Ye Fan's footprints found on the roof of the building, what does the property say?"

He Pingfei pressed the projection pen, released the shallow footprint photo on the outer wall, and the striped traces, and replied: "I asked the property manager, and he said that the property will go to the roof of the apartment every half a month to do cleaning and inspection and protection work, the most recent time was a week ago, and the staff will only work inside the fence, not down to the outer wall, the traces on this are obviously someone through the rope, stepping on the outer wall from the roof to enter the victim's bathroom." ”

As he spoke, He Pingfei released another photo, which was a photo of the entire four-unit apartment building from the bottom up, and he pointed to the wall above the window on the eighteenth floor near the top of the building and said: "This is the place where footprints and ropes were found, ...... here."

The finger moved along the place of the footprints to the position of the window on the fourth floor below, and continued: "This is the window of the victim's bathroom, we have checked the surveillance video of the fourth unit building last night, and no suspicious people were found to enter and exit, and there is no trace of damage to the door lock of the victim's house, the murderer should have climbed the rope, went down from the roof to the fourth floor, entered through the bathroom window, and after killing Li Lanke, he escaped through the window, and he was unaware." ”

He Pingfei's inference was very reasonable, but Ye Fan frowned, and the Chang team noticed her expression, leaned forward slightly, and said, "Ye Fan, what's wrong?"

Ye Fan's fingers turned around on the table, and said thoughtfully: "Judging from the on-site environment, I agree with Brother He's inference, but there is one problem, I can't figure it out." ”

"What's the problem?"

"It's cold in winter, there are vents in the bathroom, and the windows are generally closed, and the cold wind howled last night, and it was impossible for Li Lanke to open the windows wide when he was taking a bath, and like this kind of sliding windows, as long as they are closed, they will be automatically locked, if the murderer entered through the window, then how did he enter through the locked window? I have checked, there are no traces of hands and feet on the window, and the lock is intact. ”

When she found footprints on the exterior wall at the scene, she deduced that the killer had entered the victim's apartment through a window, but the locked windows made her skeptical of this inference, and she needed more evidence to support this inference.

This is indeed a big problem, the whole bathroom, except for the door that is not locked, is almost in a sealed state, how on earth can the murderer come and go freely in such a secret room, and leave no traces?

This problem will have to be investigated slowly, and maybe there are still places at the scene that they haven't noticed.

Ye Fan's fingers tapped on the table silently, it seemed that at the scene of the crime, she still had to go again, she didn't believe it, this murderer could still go through the wall like her.

This case analysis meeting did not last long, but it was longer than expected, mainly because there were more unexpected clues about the sketch provided by Ye Fan, and the others were actually not easy to analyze, or that sentence, there were too few physical evidence and clues in hand.

The forensic team had to wait for the family of the deceased to sign before proceeding with a further autopsy.

Most of the physical evidence collected at the scene of the crime has not yet been examined by the technical team, and only the physical evidence sent by the forensic team has been intensified.

Next, not to mention the New Year's Day holiday, it is estimated that it will be overtime all night again.

By the time I walked out of the police station, it was completely dark.

Ye Fanwan refused the invitation of the regular team to have dinner together, took a taxi to Rushuge, and drove back to his SUV, but did not drive back to Jinfeng Community, but went to the XX high-end apartment community, parked the car in a remote place outside the community, pasted a pseudo-spirit talisman, and flew into the community.
