Chapter 197 The Secret on the Right Foot

Chapter 197 The Secret on the Right Foot
Da Zhao's words are very reasonable, and Zhou Ning also very much agrees with this judgment.

"Well, it's possible. The key is to compare it with the surveillance video."

Da Zhao kept moving his hands, holding up a magnifying glass, carefully observing the inside and outside of the window, and suddenly saw a protruding nail cap under the window, with a white thing hanging on it, fluttering in the wind, Da Zhao stopped his movements, I picked up something with tweezers and observed it for a while.

"It's not cloth or paper. It looks a bit tough. There are some words and vertical lines on it. Wait, I know that this is a sticker on the trolley box after checking in luggage on the plane. It is used for checking in when picking up luggage. .”

Zhou Ning patted him on the shoulder and looked at Da Zhao.

"Well done, the bloodstains and this can prove that the suitcase was transported out from here. It is only a little more than three meters away from the ground outside the road. It is not very difficult to send the suitcase down with a rope or cloth strips. "

Having said that, Zhou Ning glanced at the time.

"Their physical examination wasn't done at the central hospital, haven't the files been found yet?"

Da Zhao shook his head.

"Ask Lao He, Team Tao went there yesterday afternoon, and I don't know why they didn't get it."

Zhou Ning dialed Xu Dayuan's cell phone.

"Xu Da, the figure skating team are all in the gymnasium?"

"Well, what's wrong?"

"I just want to ask. Didn't you ask team doctor Zhang to report to me the physical examination report of all the staff yesterday? No one here will send it to me. You can ask him."

"You wait."

Not long after, Xu Dayuan called back.

"They forgot, wait for me to have someone send it to you, have you found out?"

"Well, a fingertip fingerprint was found outside the window of 201, which is difficult to identify, but it can be proved that the murderer did throw out the suitcase containing the corpse through the east window of the bathroom of 201, so the vehicles entering and exiting on both sides of the road are the key points .”

"Understood, the monitoring on both sides of the intersection has been found. Although it is a bit far away, vehicles entering and exiting can still see it. The monitoring is already being called. I am glad that the monitoring time saved by the hotel is specially set, and it will take 40 days to cover. "

Not long after, Bai Ruixin ran over quickly, but he was not allowed to enter the scene. Zhou Ning went downstairs and looked through the files provided by team doctor Zhang.

There is a box for each person, and Xing Xiaoli, Wang Ying and Tan Ran brought three copies in total.

"The boss said that those children and the coaches in the team didn't take anything. After all, it has nothing to do with the case."

Zhou Ning looked at Tan Ran's file. It was very simple. It was all photocopies of various medical examination reports. The fracture marks on her leg were also reflected in the report. The rest of the biochemical indicators were not unqualified.

Zhou Ning paused when he saw the 2010 physical examination report. There was an item on it that said Tan Ran suggested removing the metatarsal nail from his right foot. There was no film and no detailed description.

Flipping forward, there was no such sentence in the 2009 physical examination.

In the subsequent medical examination report in 2011, there was no X-ray film, and there was no excessive repetition, except that there was no abnormality in one sentence.

All physical examinations were conducted in January, that is to say, after January 2009, Tan Ran was injured and had steel nails on his feet. During the physical examination in 1, it was recommended to remove them, but the physical examination in 2010 did not An exception was found.

Zhou Ning's brows were tightly furrowed, the sentence "proliferation" was too general, at this time Da Zhao ran over with his laptop in his arms.

"Zhou Xiaozhou and Lao He helped retrieve Tan Ran's medical examination file, which is a large compressed file. I downloaded it for you, but I can't understand it."

As he said that, Da Zhao had already placed the laptop on the passenger seat of the car, and clicked to open the folder.

"It's really timely. We just got the file from the team doctor. If we had called Lao He first to remind him, he would probably be blown up again."

Big Zhao grinned.

"He just doesn't have a good mouth, but he is a good person when something really happens."

Zhou Ning nodded with a smile, and moved closer to the computer.

Corresponding to Tan Ran's physical examination report, there are various X-ray examinations and CT examinations every year, and the fractures on Tan Ran's legs can be clearly seen on it. Zhou Ning zoomed in on the film and carefully looked at Tan Ran's feet.

There are obvious hyperplasia on both ankles, compared with the other side, especially on the left dorsum, except that the two metatarsals in front of the distal end have signs of fracture healing, and there are some fractures on both sides of the two metatarsals. 'Thin and small', and even some colors are 'light' in the film, and there are some dislocations.

Zhou Ning looked at the date. This inspection was done on January 2011, 1. What you see on the film can't be replaced by the sentence "no abnormality found" in the file.

Turning forward a few pages, Tan Ran's foot was intact during the examination on January 2009, 1, which was consistent with the team doctor's file, but there was no X-ray examination in 4.

Seeing this, Zhou Ning directly dialed He Shancun's cell phone.

"Hey, I have received what you sent. Please show me the X-ray of Tan Ran in 2011. Why is her metatarsal bone so weird? It looks much thinner than the other side. It seems that the steel nail has been taken out for a year. , and there are no films from 2010 in it?"

"I knew you would ask. When I retrieved the file, I found it was missing. I went to the imaging department to check it. Obviously it was not performed here. The physical examination in 2010 did not check the X-ray. Looking at the state of the metatarsal bone, the fracture After walking or exercising too early, the dislocation caused by it is estimated to have nerve damage.

Her feet look like this, and it is estimated that her legs will be different in thickness, and she will walk with a slight limp. Of course, excessive exercise will cause further damage. This cannot be corrected by training.

In addition, looking at the lateral film, it can be found that the injury was caused from the dorsal side of the foot. I don't think it was a bruise, which would cause a comminuted fracture. Her fracture section is fairly neat, but it can cause fractures of one or two metatarsals. Dorsal nerve injury is inevitable. "

"The damage to these nerves is difficult to repair, isn't it?"

"Theoretically speaking, surgery after injury can be continued, but nerves are not muscles and blood vessels. If you connect them well, the function may not recover. If you exercise too early, the consequences will be very serious. I have encountered too many patients like this .”

Zhou Ning narrowed his eyes, maybe this is the key.

"This person is a figure skater. I think the feeling on the feet is very important. If the nerve damage is serious, it will affect his sports career."

"Brother, why are you talking about sports now? What I'm talking about is that as a normal person, she can tell when she walks, even if she controls her movements, she can feel weird movements. Doesn't she know?"

Zhou Ning hung up the phone, tapped his fingers on the computer screen, and Da Zhao came over directly.

"Since our investigation, no one in the figure skating team has ever said that Tan Ran was injured, and according to these files, she was injured in early 2009, and it was around this time that she and Xing Xiaoli stopped forming a team. Obviously, they all knew that Tan Ran was injured. It's a matter of being injured, but how did you get hurt?"

Zhou Ning closed the computer and got into the car directly.

"Call Yang Xuetong and the others and ask them to continue their investigation here. They must check the windows of the bathrooms in 301, 401, and 501 upstairs. Let's go to the gymnasium to find Xu Da."

Da Zhao knew that Zhou Ning must be thinking of something, so he started the car and rushed out without talking nonsense.

It took a few minutes to arrive at the gymnasium, and went up to the third floor. In a simple office, people from the technical department were sorting out the monitoring. Zhou Ning glanced at it and said that it was all right to find Xiaoqu. It was still effective when I said it last time.

Just as he was about to touch his phone, Xu Dayuan came from not far away, and when he saw Zhou Ning, he quickened his pace.

"What, what did you find?"

Saying that Xu Dayuan had closed the door, several people walked to the corner of the office, and Zhou Ning put Tan Ran's medical examination box on it.

"Old He retrieved their annual physical examination files, which were somewhat different from what team doctor Zhang provided, and Tan Ran suffered a serious foot injury in 2009, resulting in a metatarsal fracture.

I talked with Lao He. From the later films, her recovery was very bad. She felt that she had exercised too early, which affected her healing. Some bones were misaligned, and her nerves might be damaged. One leg was thick and the other was thin, and she was walking. We can see the abnormality, but the corpse is already highly decomposed, so we can't find the abnormality.

But since the beginning of the investigation, no one has mentioned this issue, and in April and May 2009, Tan Ran and Xing Xiaoli disbanded the combination and began to practice solo separately. Is this also related to this?

Also, I analyzed it with Lao He. After all, metatarsal fractures are usually caused by crushing injuries, and they are all comminuted fractures. However, Tan Ran's fracture surface is neat, and it looks like it was hit by some hard object with sharp edges. chop. "

Da Zhao listened carefully, but after Zhou Ning finished his analysis, he shouted in surprise:
"Sharp hard objects are still neat, so do the skates count?"

Zhou Ning was startled, and Xu Dayuan's eyes lit up.

"This analysis is very reliable. As a figure skating athlete, it is very easy to touch skates. I remember that speed skating teams are often cut by ice skates, and their clothes are made of special materials."

Zhou Ning raised his foot and put it on Xu Dayuan's foot, but it didn't fall.

"It makes sense, but ice skates are the most likely to cause cuts, which can cause fractures of this degree. The force of this pedaling is very strong, and it is not as simple as stepping on one foot."

Da Zhao blinked his small eyes, and pressed his hand on the computer.

"Conspiracy theory, if Xing Xiaoli accidentally hurt Tan Ran, the two of them were still in a team at that time, and Tan Ran liked Xing Xiaoli, you said she would tell the outside world that she was hurt by Xing Xiaoli? And was the injury serious?"
