Serious Crime Unit 1

Chapter 866 Allergies (3)
Wu Jiang and Xiao Ke quickly found the place where the murderer sexually assaulted Zhao Yaxin. It was located in the woods to the north of the park. It was surrounded by a hill to the east and flat land to the west. It was filled with dense camphor trees, some of which were as tall as 6 meters, the woods are full of green grass.

Under a camphor tree, there are traces of someone running over a piece of grass. Some of the grass has been torn off, and the broken branches have withered. The grass that has been crushed into a lodging shape has not yet grown straight. There is a glass button on the grass, and Zhao Yaxin's shirt. The buttons that were torn off were exactly the same, so Wu Jiang and Xiao Ke thought this was the place where the incident occurred.

Because this is the junction of flat land and mountains, few people come here to play. Therefore, the site is still completely protected. The grass grows sparsely on the ground, exposing the black earth, so there are many footprints imprinted on it.

Xiao Ke took photos and extracted the suspicious footprints. One type of shoe print was size 41, which was left by a pair of sports shoes. However, he didn’t know the specific brand of shoes. He had to take it back and compare it on the computer to make an accurate decision. judgment.

Another type of shoe print was size 39. Wu Jiang looked at it for a while and said to Xiao Ke: This is the shoe print of a pair of Adidas sneakers produced in the winter of 2018. I have seen Zhao Yaxin’s shoe print and confirmed that it is her shoe print.Xiao Ke nodded and agreed with Wu Jiang's view.

They also extracted semen on the grass. Due to the sunlight, the semen had solidified and turned yellow. They concluded that it should have been left by the murderer.If the murderer is caught and brought to justice in the future, this evidence will be enough to form a complete chain of evidence, which will be very beneficial to the prosecution.

They found a monitor 30 meters away from the incident site, facing the incident site. However, because April to May is the season when camphor trees change new leaves, the monitor was blocked by the lush leaves. , unable to capture the situation at the time of the incident.

Wu Jiang entered the extracted shoe prints into the computer and searched them in the database. The results did not match. This was expected, indicating that the murderer had no criminal record. However, the computer showed that these were a pair of Anta sneakers produced in the spring of 2019. , the financial ability of the person wearing such shoes should not be high. Of course, it cannot be ruled out that the murderer deliberately wore such shoes to confuse the police.

Lu Yingying and Wen Xiaorou entered the surveillance system of the suburban park. Under the guidance of Xiao Ke, they specifically checked the monitor facing the crime scene. However, because the camphor tree leaves were too dense and the lights were dim, they could not see the murderer when he committed the crime. In this situation, the murderer must have visited the suburban park, otherwise, he would not have chosen to sexually assault Zhao Yaxin at that time.

Through the analysis of the shoe prints, Wu Jiang determined that the murderer was about 174 to 176 centimeters tall, weighed 75 kilograms, and had an outstretched gait. Because the shoes were relatively new and the soles were not significantly worn, it was impossible to determine the murderer's occupation.

Wu Jiang asked Lu Yingying to look for the suspect whose height and weight matched the surveillance video. Lu Yingying felt that the suspect would not escape from the two gates of the suburban park, but would escape from any wall in the park, so she asked Wen Xiaorou to lead the surveillance video. The detective team checked the surveillance video outside the park wall, and she checked the surveillance video inside the park.

Viewing surveillance video is like looking for a needle in a haystack. First of all, not knowing the suspect's face is like a rifle without a scope. You can only check based on experience and feeling. Secondly, although there are traffic monitors and security monitors outside suburban parks, , however, it would take thousands of hours to review all these surveillance videos, and the workload is obviously huge.

Fortunately, on the afternoon of the next day, Wen Xiaorou discovered something: at 2019:4 on April 15, 23, a man wearing a mask jumped from the fence at the northwest corner of the suburban park onto the road, then walked towards a motorcycle and sat on it. After going up, press the switch, start the electric bicycle, and drive northwest along Huanshi North Road.

Judging from the surveillance video, this person is highly suspicious. His height is similar to that of the owner of the shoe prints extracted at the crime scene. Judging from his body shape, his weight is also similar. Wen Xiaorou called Wu Jiang and Xiao Ke for analysis. , they both felt that Wen Xiaorou’s judgment was correct.

Now the work is much easier because I have a goal.Everyone followed the traffic surveillance video to track the suspect. However, the suspect seemed to be deliberately playing hide-and-seek with them, driving back and forth on the approximately three square kilometers of road. Finally, the suspect drove the motorcycle to the foot of Longtou Mountain and left the bicycle behind. It was abandoned on the roadside and climbed up the mountain. From then on, there was no surveillance video and the whereabouts of the suspect could no longer be seen.

Lu Yingying arranged for people from the visual investigation team to take turns watching the electric bicycle. As a result, they watched the video for two days and found that the suspect never came back to ride the electric bicycle.Lu Yingying started to check the current surveillance video, and found that the dilapidated bicycle was still parked on the roadside.

Longtou Mountain covers an area of ​​more than 100 square kilometers. The top of the mountain reaches an altitude of 1150 meters, which is very different from the provincial capital's average altitude of more than 80 meters. The foot of the mountain is connected by dozens of hills, and dozens of villages are scattered in large and small valleys. 3 villagers.

Wu Jiang and Xiao Ke drove to the location where the suspect abandoned his car, and sure enough they saw the motorcycle.Because there were many passing vehicles on the road, the electric bicycle was already covered with dust. They checked the entire vehicle and found several fingerprints on the handlebar. Wu Jiang took out fingerprint powder and extracted the fingerprints.

Then they carried the motorcycle to the trunk of the police car and transported it back to the criminal police team, hoping to extract biological samples from it for DNA testing, but the results disappointed them.Wu Jiang entered the suspect's fingerprints into the database for comparison, but the result still failed. This once again shows that the suspect's anti-investigation ability is very strong.

Wu Jiang had no choice but to upload the suspect's fingerprints to the collaborative case handling system. If the suspect is caught by the police for committing another crime, he can be brought for interrogation. However, the probability of this is relatively low. Unless the time is very long, it will be difficult. In this way, the suspect is arrested and brought to justice.

Jiang Yiming and Xiao Ke visited Hu Feixue, and his answer was similar to the answer he gave in the morgue last time: Many of Zhao Yaxin's relatives and friends knew that she was allergic to penicillin.This statement is of little value and is questionable. How could Zhao Yaxin casually tell others that she is allergic to penicillin?Jiang Yiming thought it was best to ask Zhao Yaxin's parents. He asked Hu Feixue to write down the address, name, and mobile phone number of his father-in-law and mother-in-law and give them to them. Hu Feixue was reluctant, but had no choice but to bring a piece of note paper and follow the requirements. Write it down and give it to Jiang Yiming.

Jiang Yiming took the note and looked at it: Father-in-law: Zhao Yue, mother-in-law: Guan Xin, address: Room 147, Building 18, Feicui Community, No. 202 Huanghe Road, Jiangbei District.Also below are their mobile and landline numbers.Jiang Yiming entered Zhao Yue's mobile phone number into the dial pad of his mobile phone and dialed. The call was quickly connected and the other party answered. Jiang Yiming explained the situation to him and he promised to wait for them at home.

They came to Feicui Community and found Zhao Yue's home. Zhou Ting went to ring the doorbell. The doorbell rang for a long time before a middle-aged man in his sixties came to open the door. After Zhou Ting introduced himself, the other party said his name was Zhao Yue, Zhao Yaxin's father, then invited them in to talk.

Zhao Yue's face was pale and haggard, his expression was depressed, his eyes were dim and lifeless, and he looked very sad. This should be caused by the sudden death of his beloved daughter.He was tall and thin, wearing a black suit, a white shirt underneath, and a pair of casual pants.

"Uncle Zhao, have you retired?" Jiang Yiming wanted to make some preparations before getting to the point. After all, it is extremely painful for a white-haired person to send a black-haired person away.

"I haven't retired yet, but I have retired to the second line and worked as the deputy secretary of the Jiangxi District Industrial and Commercial Bureau. Alas, I am getting old. I can't accept it anymore." He said with disappointment.

"You don't look old, you are still very young."

"Thank you for your compliment! I heard that my daughter's death is a dispute among you, right?" He was eager to know the result.

"There is no dispute anymore. Zhao Yaxin was murdered. The murderer..." Jiang Yiming stopped here. He did not want to tell Zhao Yue how the murderer sexually assaulted Zhao Yaxin, for fear of causing him greater sadness.

"Captain Jiang, just tell the truth. I can bear anything but lies, even if they are well-intentioned." He nodded to Jiang Yiming, encouraging him to tell the truth.

"Okay, let me tell the truth. Zhao Yaxin died of shock due to an allergy to penicillin and was not rescued in time. She was sexually assaulted by a murderer before she went into shock. Penicillin was introduced into Zhao Yaxin's body in this way. The murderer was a cunning person. A cruel devil."

"How... is this possible? The person who murdered my daughter in this way must be a doctor." He shook his head, feeling incredible.

"With the development of society, criminals' criminal methods are also constantly upgrading. At first, we did not understand how penicillin entered Zhao Yaxin's body. Later, after our forensic autopsy, we found the reason. Please forgive me and we will definitely bring the murderer to justice. Bring her to justice and make Zhao Yaxin smile."

"Not many people know that my daughter is allergic to penicillin. If you didn't mention it, I would have forgotten about it."

"We just want to know the situation from you today. Does anyone know that Zhao Yaxin is allergic to penicillin?"

"Besides her mother and me, only my son-in-law should know..." He was suddenly stunned for a moment and realized that he had made a mistake. How could Hu Feixue kill his daughter?
"No, will the doctors who treat Zhao Yaxin know that Zhao Yaxin often gets sick?"

"She suffered from chronic pneumonia when she was a child. The doctor wanted to give her penicillin. Before giving her penicillin, she did a skin test and found that she was allergic, so she did not give penicillin. Later, her pneumonia was cured. In the past few years, she has suffered from chronic pneumonia again. She often goes to the doctor for pharyngitis, so the doctor will definitely ask her if she is allergic to penicillin."
