This scene surprised Cheng Yijie, Mu Qingcheng and Chen Yufei. "Please, don't ask, don't ask again!" Xiao Yuan cried breathlessly, just begging intermittently, "Please...... I can't say ......"

"Well, let's change the subject." Cheng Yijie looked at Xiao Yuan, who was trembling from crying, "On the night of February 15, did you drive to Fisherman's Wharf?" ”

Xiao Yuan raised her head suddenly, and her gaze went straight to Cheng Yijie. "No, I've never been to any Fisherman's Wharf!" She said in a hurry, "On the night of February 15, I didn't go anywhere, I was at home. ”

"At home?" Cheng Yijie snorted lightly, "It's been so long, how can you remember it so quickly, it's at home?" ”

"I ......," Xiao Yuan twitched, "because...... Be...... The second day of Valentine's Day...... No one to accompany ......"

Cheng Yijie and Chen Yufei glanced at each other, and Chen Yufei no longer pressed questions, and said coldly to Xiao Yuan: "If you still have a conscience, please treat that child well, don't let him be hurt again, and it is also the teacher's duty to protect the students." She handed over a business card and asked Xiao Yuan to call her if she had anything she wanted to say or remembered.

Xiao Yuan took the business card and still knelt on the ground, bursting into tears.

Cheng Yijie, Chen Yufei and Mu Qingcheng left the kindergarten.

"That Xiao Yuan, there is definitely a problem." Chen Yufei said with certainty, "When you asked her about her whereabouts on the night of February 15, did you suspect that the woman who went to the boat with her suitcase was her?" ”

Cheng Yijie nodded and said: "Although the woman in the surveillance screen wraps herself tightly, after I see Xiao Yuan, I can still be sure that she is that woman." As soon as I tried it, she immediately showed her flaws. For a person like her, who is prone to panic in trouble, it is impossible to plan a well-thought-out murder case, someone must be behind it. Moreover, Xiao Yuan looks a little thin, although the skeleton of a dead man is not too heavy, it is also very difficult to carry a large suitcase containing the skeleton to the mountain by himself. ”

She drove Nanwei's car and took the suitcase containing the skeleton to the mountains of Li Island and discarded it. It's easy to think of the person behind the scenes. Chen Yufei said, "I will immediately investigate the relationship between Shen Juntian and Xiao Yuan." ”

Mu Qingcheng listened to their conversation, and only felt a chill rising from his heart, could it be that the couple joined forces to commit the crime? So who is it that is so cruel to their children? "No, there's no way Nanwei was involved in the homicide." She subconsciously defended Nanwei, "

On the painting boat that night, I still remember what Nan Wei said. She said that if you put aside the so-called pursuit and change to a different mentality, and do things completely out of kindness to others, completely out of dedication and love, you are happy. On the contrary, if you blindly demand and demand, once you can't ask for it, you must be miserable. Nan Wei, who is committed to advocating the use of the correct sound of the guqin to correct the heart and cultivate the body, how can she harm others, and how can she allow her hands to be stained with blood. ”

"It's hard to say, human nature has an evil side." Chen Yufei has a different opinion, "Even at a certain moment, I will have a strong killing intent. Many people do it on the spur of the moment. I have seen too many such people, their essence is not bad, but one thought becomes a demon, and one mistake turns into a thousand hatreds. ”

Cheng Yijie did not express his opinion, but said: "Let's talk about the case of Ni Yanlin's murder, I have found the key to narrowing the time frame of the presumption of death." He told Chen Yufei in detail about his previous discoveries in the mountain col.

"The time of Ni Yanlin's death was actually between 1 o'clock and 1:20 p.m." Chen Yufei thought and said, "Then the number of suspects has also decreased, between 1 and 1:20, there is no alibi, only Xu Qiaoling, Xu Youran, Wan Lun, Zhong Chun, Shen Juntian and Fang Qianqian are left." If the tryst men and women found by Xie Jiaqiang were indeed Shen Juntian and Fang Qianqian, they still had the time to commit the crime, and when they asked about the alibi of the two, they all said that they went back to their residence to rest, from this point of view, what Xie Jiaqiang said should be right. ”

The next morning, Xiao Yuan's body was found by the Qianjiang River, and it was preliminarily concluded that he had drowned, and the specific circumstances could not be known until after an autopsy. Judging from the abrasions all over the body, it may have drifted down from somewhere upper.

The time of death is presumed to be between 11 p.m. yesterday and around 1 a.m. today. According to the police station in the jurisdiction, there is a bridge two kilometers upstream from the crime scene, and a pair of shoes were found on the side of the guardrail of the bridge, and the shoes were neatly placed on the ground when they were found. The shoes are confirmed to be Xiao Yuan's. There are various indications that Xiao Yuan committed suicide by throwing himself into the river, but whether it was suicide or homicide remains to be further investigated.

The bridge is in a relatively remote area, the bridge deck is narrow, large vehicles cannot pass, and the bridge deck is dimly lit, there are few vehicles and pedestrians in the middle of the night, and no witnesses can be found.

The medical examiner's autopsy report indicated that Xiao Yuan's cause of death was death caused by an external impact on the skull. Xiao Yuan's residence is not far from the bridge where the shoes were found. After investigation, at about 12:15 p.m. last night, a taxi driver picked up a woman in front of the apartment building where Xiao Yuan lived, and the destination was the bridge where the shoes were found. The ride record also records that at 12:16 a.m., he departed from the front of the apartment building where Xiao Yuan lived and arrived at the entrance of the bridge, and it was confirmed that the time of getting off the bus was consistent with the presumed time of death.

According to the driver, the woman was dressed strangely at the time, covering her face with a headscarf and wearing sunglasses. Chen Yufei took out a photo of the surveillance screen of Fisherman's Wharf for the driver to identify, and the driver confirmed that the woman was exactly the same dress, but because he couldn't see her face clearly, he couldn't confirm whether it was the same person.

At the case seminar of the criminal police team, many people believed that Xiao Yuan committed suicide because of the revelation of the crime. But others, including Chen Yufei, disagreed, saying that the motives and actions of the night were indeed reasonable, but it felt unnatural, and that a person who wanted to commit suicide should wrap himself tightly if he was going to die. The most likely thing is that she was killed because the matter was revealed.

Chen Yufei went to the bridge where the shoes were found again, looking for witnesses. On a cloudy day, the wind is strong and whirring on the bridge, and the muddy river under the bridge is surging. She stood in front of the guardrail, her long hair was blown by the wind, she stood in the wind for a while, looked down at the ground, suddenly thought of something, and immediately called the meteorological station to verify.

According to information from the Meteorological Observatory, at 1 a.m. on the night of Xiao Yuan's death, the maximum wind speed on the bridge was as high as 22 m/s, and the wind force reached 9, after which the wind gradually weakened. Xiao Yuan's time of death is inferred to be between 11 p.m. and 1 a.m., if she committed suicide and found her shoes, they could not have been neatly placed on the ground in front of the guardrail, but had been blown away by a level 9 wind. Then, the shoes were placed after Xiao Yuan's death

There are surveillance videos at the entrance and exit of the bridge, and a review of the surveillance video found that the woman suspected of being Xiao Yuan went on the bridge at 12:45 and never appeared again. At 1:16 a.m., the BMW sedan owned by Nan Wei appeared at the entrance of the bridge and drove out from the other end of the bridge about 15 minutes later.

After identifying the surveillance footage, Cheng Yijie concluded that the woman suspected of being Xiao Yuan was not Xiao Yuan herself, just like Xiao Yuan pretending to be Nan Wei last time, this time someone was pretending to be Xiao Yuan. He believes that the bridge is not the scene of the first crime, it is the car that was thrown away after death, the woman who pretended to be Xiao Yuan, after the person who assisted the driver on the bridge to throw the body, got into the car and left with the car, so she did not appear in the surveillance screen again, creating the false impression that Xiao Yuan took a taxi to come and committed suicide by throwing herself into the river from the bridge.

Chen Yufei and his partner Zhao Jun went to the apartment where Xiao Yuan lived, the apartment was located on the second floor, and when they opened the door, it was a mess inside, obviously showing signs that someone had rummaged through the cabinets. After inspection, wallets, passbooks, cards, etc. were all there, but the desktop computer on the computer desk was gone, only the wires and network cables that were previously connected to the computer remained.

The two walked out of the apartment to find out what was going on with their neighbors, but the apartment building was new, the occupancy rate was low, and nothing was found. After going downstairs, they saw a convenience store across the road from the building, so they went into the store and asked the proprietress who was busy alone if she had seen anyone entering or leaving the apartment building last night, or if there was anything unusual.

"There was a car parked downstairs all the time, and it was there at 11 o'clock, I don't know if it counts." The proprietress recalled, "There was no one living in that building, and I hadn't seen a car parked before, so the car was particularly eye-catching." The car didn't turn off, someone was in the car all the time, but the lights weren't on, so I couldn't see who it was. I was supposed to close at 11 o'clock, it just so happened that there were guests who came last night, chatted and chatted until 12 o'clock, the car was still there when I left, it had turned off, there was no one in the car, when it left, I didn't pay attention. ”

"Is it a silver-white BMW?" Chen Yufei verified.

The proprietress replied yes, when the car drove in front of the convenience store, she could clearly see that it was a silver-white sedan, with a person sitting in the passenger seat, and she also recognized the BMW logo, and remembered that the last two digits of the license plate number were "88", such a number was particularly easy to remember.

According to the information provided by the proprietress, it can basically be determined that what was parked downstairs at that time was Nanwei's car. Where did the people in the car go at 12 o'clock? At 12:16, the woman pretending to be Xiao Yuan took a taxi in front of the apartment building to leave, and there must be some kind of connection between the two. Then the first crime scene mentioned by Cheng Yijie should be in the apartment where Xiao Yuan lives.
