Li Yiting stood in the ward where Zheng Jun lived before, looking around, everything here has not been passive since Chen Qian fell from the building, and it is precisely because of Zheng Jun's accident that has happened here, so this ward has not been arranged to have other patients for the time being, that is to say, if Chen Qian really appears here at the end, this will become a crime scene that is still intact.

Police technicians are searching the room, so far no valuable clues have been found, everything in the room is arranged in order, the pillows and quilts on the hospital bed, the hanging bottle shelves next to it, and the folding chairs where the escorts are sitting, are all quietly left in the right place, in short, it is very calm, there is no sign of a fight.

But it was this situation that made Li Yiting even more uneasy, because on the ground, the technicians did not extract the complete footprints, which is unbelievable. If the previous imprints were cleaned by cleaning staff, then after Chen Qian came here at noon, at least her footprints should have been left on the ground. But the fact is that the police failed to find a complete footprint, there are a lot of footprints, but most of them are superimposed, in other words, even if Chen Qian came here, she should have been walking back and forth in the house, not directly walking to the window and jumping down after entering through the door.

The window is open outward, there are obvious marks under the ground, which can be distinguished by the naked eye, and the technician told Li Yiting that there are indeed footprints there, compared with other areas, it is relatively perfect, and basically can be compared with the deceased's shoes from part of the interception, and the police have already done this work.

Looking out of the window to the ground, you can just see the place where Chen Qian died, Li Yiting once again used the parabolic theory to deduce in his mind, and it was basically the same as when he was below, from the height and angle here, there is a theoretical possibility of falling to that position.

At this time, Xu Jingnan rushed over, he was busy for a long time, and finally conducted a preliminary autopsy on Chen Qian's body, except for the part that needed to be tested, the other results were presented in the preliminary autopsy report he brought.

Li Yiting was still looking out the window, he didn't read the report, but asked Xu Jingnan to read it to himself.

"The deceased Chen Qian, fifty years old, with a net height of one meter five or eight......" Xu Jingnan read it at a glance.

"You don't need to be so formal, you just say the result. Li Yiting interrupted him.

"Good teacher, the deceased Chen Qian had obvious visceral hemorrhage and open fractures of the sternum, back bone, and skull, and suffered a gravity impact before her death, and the cause of death was falling to the ground from a high altitude. ”

Xu Jingnan directly skipped the process and said the conclusion according to Li Yiting's request, but when he finished speaking, Li Yiting didn't say anything for a long time, still staring at the window. Xu Jingnan was a little puzzled, waited and waited, and saw that Li Yiting didn't mean to speak, so he simply repeated the conclusion again.

Li Yiting turned his head at this time, but he was not interested in the autopsy report, after all, this conclusion was basically similar to the previous speculation, and he was just signaling Xu Jingnan now to see the direction of his finger.

Xu Jingnan found that Li Yiting's outstretched palm was pointing to the lower edge of the window, not the grass and trees outside. At the lower end of the window, there was some dust, as if it hadn't been cleaned for a while, Xu Jingnan stepped forward, and found a few places that were not obviously clean in a pile of dust.

"Teacher, is this a fingerprint?" Xu Jingnan suddenly realized.

"Whether it's or not, try to extract it and see if there are any fingerprints. Li Yiting said calmly, this is actually the biggest discovery he made after he came here.

Xu Jingnan immediately started to take pictures and took fingerprints, thanks to the fact that this ward has been unoccupied for a long time, so it is stained with dust, otherwise it is indeed difficult to find this hidden clue.

Li Yiting asked Xu Jingnan to go to the police station immediately, and through technical means, compare the fingerprints, footprints and other clues found here with Chen Qian, after all, the test results of Chen Qian's body will be found as soon as possible. Although in the eyes of outsiders, Chen Qian committed suicide by jumping off the building, everything is reasonable and there are no obvious loopholes, but for such a coincidence, Li Yiting just can't easily make a conclusion, this is also the criterion of being a detective, everything must be based on evidence, not to mention that he inadvertently found several flaws, waiting to be solved one by one.

Just when the hospital's investigation was proceeding in an orderly manner, Wan Yongkun and Fat Sheng had already followed Li Yiting's instructions and came to Chen Qian and Zheng Jun's hometown.

But as soon as they arrived in the village, Wan Yongkun and Fat Sheng encountered a problem, that is, they didn't know the inside story of the medical trouble, but they only knew Lu Gangqi from the investigation in Beiting. If they don't know the situation of the medical trouble, then pretending to be such an identity is definitely not like it, and they have not participated in the incident of Dr. Zheng's trouble, and these family members have not seen it, so it is not easy to be believed.

Li Yiting also knew that it was difficult to do this, but the other members also didn't know about medical troubles, in fact, the entire Beiting had not dealt with similar cases, so they had to work and study while working in the process of investigation, which undoubtedly brought difficulties to Wan Yongkun's infiltration. Li Yiting meant that if he couldn't get involved as a doctor for the time being, then through Wan Yongkun's powerful tracking ability, he would first find out the movements of the people involved in Zheng Jun's case, and then follow Lu Gang, the head of the medical trouble, to find tiny clues from the periphery, and then slowly enter the core area. In this way, the progress must be very slow, but Chen Qian's sudden death made Li Yiting think that he couldn't wait any longer, otherwise these experienced family members might collude with the doctors and make a comeback after hearing that Chen Qian died in the hospital and fell downstairs. In that case, things will fall into a more complicated and tricky situation, so in the midst of extreme difficulties, letting Wan Yongkun start to understand from the outside is almost the only safe way in the short term, and now it can only take one step at a time.

Wan Yongkun walked around the village, he definitely couldn't reveal his identity easily, but it was difficult to contact, just when he was a little anxious, the person who had saved his life appeared in front of him.

Yege didn't actually come with Wan Yongkun, he came here as soon as he heard that Chen Qian died, just because he was worried that the relatives of the Zheng family would come to make trouble again, and Zheng Jie had already been let go home, so he wanted to find out first, and then warn Beiting.

Under the unexpected meeting, Ye Ge suddenly had an idea, because he met Zheng Jie in front of the hospital in Lu Gang's team, the other party should have an impression of him, so he led Wan Yongkun and Fat Sheng, lied that they were from the medical team, and went to Zheng Jie together.
