Chapter 13 Chapter Twelve

"Boss, Ye Yuanchao's shoes are all size 41." As soon as he returned to the county bureau, Zhang Yiang reported to Gao Dong with the investigation records. "All shoes?" "Yes, we went to his house today. On the shoe cabinet in front of his house, there are four pairs of shoes, two pairs of leather shoes, a pair of casual sneakers and a pair of sneakers. They are all size 41. The pair of leather shoes on his feet are also size 41. .” Gao Dong thought for a moment, then asked, "Are all the shoes old?" "right." Gao Dong nodded: "This shows that the shoes that Ye Yuanchao usually wears are indeed size 41. However, this does not rule out the possibility of his crime. The murderer left no clues, except for a shoe print. It is possible that the murderer intentionally wore a pair of size 40 shoes during the crime to interfere with our investigation."

When Zhang Yiang heard this, his face showed embarrassment: "Then we have to search his house with a search warrant?" Gao Dong smiled: "Let's talk about it later. Applying for a search warrant without evidence and evidence to investigate a policeman is against the rules. If the case really has nothing to do with Ye Yuanchao, you have already searched for him twice, and it would be bad to go again." Zhang Yiang said with a wry smile: "Yes, the people at the police station made faces when they saw us, and they almost kicked us out." Gao Dong laughed and comforted him: "Thanks for your hard work. How about the alibi check?"

"At around 5 p.m. on November 25th, Ye Yuanchao ate at a small restaurant downstairs of his house. We have confirmed this with the owner of the restaurant. Ye Yuanchao often ate there. Afterwards, Ye Yuanchao said that he would go home and watch TV, on the Internet for a while, and never left the house. We checked his computer, and there was indeed a record of his surfing the Internet on the night of November 25.” Gao Dong narrowed his eyes slightly and asked, "What website does he go to?" "Baidu, Sina, Netease, Tianya, basically read news pages." "What news does he watch?"

"Mostly domestic political and factual news." "Has he ever been on a website that is inappropriate for his age?" Zhang Yiang glanced at the investigation records and shook his head: "No, watching these political and people's livelihood news should be in line with his behavior." Gao Dong nodded and continued to ask: "What time did he visit these websites?" "The history of the browser only saves the day when it was viewed, and does not record the specific time and minute. Later, Xiao Liu looked for his hard disk records and found out that the time of surfing the Internet was between 7:00 and 7:30 that night."

Gao Dong narrowed his eyes slightly: "If he's still online at 7:30, he won't have enough time to kill people. Um... By the way, have you asked the broadband operator to check his home's online time?" "I've checked, and now all the shared bandwidth in the community is used in the area, so the broadband operator does not record the usage traffic of the user's home in each specific hour, but only records whether the user is connected to the Internet on a certain day. Since Ye Yuanchao's home is installed router, so the broadband operator’s record is that Ye Yuanchao’s home has been connected to the Internet all the time.”

Gao Dong thought about it, and said, "By the way, Ye Yuanchao said that he played the stand-alone version of mahjong on the computer on the night of November 25th. Have you checked the latest access time of the mahjong file?" "I checked, the latest interview was yesterday, so there is no way to know whether he also played on November 25." Gao Dong let out a breath, and then asked, "Is there a surveillance camera near Ye Yuanchao's house? If so, we need to check whether he really didn't leave the house on the night of November 25." Zhang Yiang said: "We took a look around, that area is the old city, there are very few surveillance cameras, the nearest one is about five or six hundred meters away from his home, it is an intersection surveillance, even if he leaves the house, there is no need Go under that surveillance camera. Boss, Ye Yuanchao went online at 7:00 pm on November 25th, the evidence is convincing, you can completely rule out suspicion, right?"

Gao Dong didn't answer directly, turned around, thought for a moment, finally sighed, and decided to let Zhang Yiang go back and continue to investigate Wang Baoguo's interpersonal relationship, so let's stop with Ye Yuanchao's matter for the time being. He reorganized his thoughts.There is a certain possibility of Ye Yuanchao committing a crime, but the suspicion can basically be ruled out. First of all, from the motive point of view, if he wants to take revenge because of the breakdown of his family, he should go directly to Shen Xiaoxian's family instead of Wang Baoguo who is in an indirect relationship.

Secondly, a size 40 shoe print was left on the scene. Several pairs of Ye Yuanchao's shoes were all size 41, and they were all old shoes.It shows that he usually wears size 41 shoes.If they are all new shoes, then you have to suspect that Ye Yuanchao bought a size 41 shoe to show his appearance after the murder, so as to get rid of the suspicion. Another hypothetical point of view, if Ye Yuanchao deliberately wore a pair of shoes of a different size from his usual size when he committed a crime, and deliberately left a shoe print to mislead the police during the murder, then he should wear shoes of size 42, not 40 yards.Because a person is very uncomfortable wearing shoes that are smaller than their actual foot size, and they can't move freely. This critical murderous moment must not have a lack of movement.If you wear shoes that are one size larger than your actual size, you can eliminate the impact by stuffing the insole and tightening the straps.

Again, it has been confirmed that Ye Yuanchao ate downstairs at 5 pm on the day of the incident.Afterwards, he returned home. Although there was no witness to prove that he had never been out of the house, he did surf the Internet between 7:00 p.m. and 7:30 p.m. on November 25th. Besides, he had no way of predicting that Wang Baoguo hadn't returned home at that time. Of course, Ye Yuanchao can also download a software to automatically surf the Internet, and fake the illusion that he surfed the Internet that night.However, based on the common information that Gao Dong obtained from Jiang Wei, Zhang Yiang, and other people who had contact with Ye Yuanchao from the county bureau, the image of Ye Yuanchao outlined by Gao Dong was an aggrieved good old man, not a logical and impeccable smart person, and also I don't know much about computer technology.Such a person would not come up with a whole set of alibi perjury.

From the criminal motive, the evidence left at the scene and the alibi, the possibility of Ye Yuanchao's crime was almost ruled out. In addition, when Zhang Yiang approached Ye Yuanchao twice to investigate, Ye Yuanchao's attitude and reaction characteristics were also completely in line with his psychology. At this point, Gao Dong finally excluded Ye Yuanchao from Wang Baoguo's case. But he still has a bigger problem, who killed Wang Baoguo?Witnesses saw that the guy who was walking slightly to the left and moving in a hurry was the murderer, or just an ordinary passerby?
