Mystery Hunter

"What?" Xiao Xuanmiao opened her mouth as if she couldn't believe her ears, and immediately asked.

The female reporter said slowly, "It's that Ge Dongyun who bullied you, she's dead."

Xiao Xuanmiao shook her head, her face full of shock: "Ge Dongyun, how did Ge Dongyun die?"

"The police are still investigating." The female reporter said slowly: "But it is very likely that the murderer who left the note earlier."

Xiao Xuanmiao put her hand on her chest, she was obviously frightened: "I, I don't know what to say now, but I have already forgiven Dongyun and the others, if it's for me, I beg everyone. Don't do this. If it's the murderer, I want to tell him that killing is a crime, and any reason is not a reason to kill. If you don't surrender as soon as possible, the uncle of the police will catch you soon!"

Although Xiao Xuanmiao's voice was soft, her words were powerful.

"Yes, Xuan Miao is right." The female reporter also said, "Murder is a crime, no matter what the reason is."

After speaking, the female reporter comforted: "But Xiao Xuanmiao, don't take all this to heart. You should close your old life yesterday and start your new life."

At this moment, Guan Deng handed Jiang He a note.

Jiang He saw that there were numbers on it. To be precise, these numbers were time. Jiang He immediately understood what it meant: "Time for the access card?"

Guandon nodded.

Jiang He looked at the numbers on the note: 8:18, 8:39.

"Is this today?" Jiang He asked.

Guan Deng quickly typed on his mobile phone: "This access control system is not connected to the Internet, and only has a simple arrangement of binary information. In short, it can only record the recent two records. If the door is opened again by the access control, the subsequent records will be recorded. The first record is topped off."

"In other words, these two times are the most recent records of using the access card to open the door." Jiang He asked.

Guan Deng nodded and continued typing on his mobile phone: "Only with an access card to open the door will there be such a record, and opening the door from the inside will not generate a record."

The most recent record of using the access card to open the door was at 8:39, while the last time the door was opened was at 8:18. The last time should be when Mother Ge came back, which is 8:39. But at 8:18, who in the end came back? And came back with an access card.

There were three access control cards in total. There were three judgments placed in front of Jiang He. First, this card belonged to Ge Dongyun, second, this card belonged to Ge's mother, and third, this card belonged to Ge Dong Ai.

If the murderer gets hold of any of these cards, he can enter directly through the door. And there is no surveillance of the building nearby, the murderer can easily sneak into Ge Dongyun's house, and then wait for the opportunity to enter Ge Dongyun's bedroom. And of course, if the murderer didn't get the access card, then there are three other possibilities.

First, Ge Dongyun had left, and then returned home at 8:18. Second, when Mother Ge came back, she lied, and she came back twice in total. Third, Ge Dongai ran back from kindergarten.

And each of these three possibilities has contradictions and points of inexplicability.

If it was Ge Dongyun, where did she go when she left, and if it was to receive express delivery, she didn't need to lock the door, did she go to meet someone? After coming back, I slept again. During this period, the murderer probably sneaked into Ge Dongyun's bedroom in some way, and then waited for Ge Dongyun to come back.

If it was Mother Ge, but during that time, she should have been shopping at the vegetable market, and she had sent a text message to Ge Dongyun at 8:21, which was almost impossible.

It is even more impossible for Ge Dongmei. A child who goes to kindergarten and comes back from school and kills someone is almost even less likely than the third world war.

While Jiang He was thinking, the security captain walked back. Jiang He did not ask about the video material, but asked, "Did Ge Dongyun's stepmother, Ms. Wang, drive her son in the morning?"

Although the security captain didn't expect Jiang He to ask this question, he still replied, "Yes, I drove there."

"When did you come back?" Jiang He asked again.

"When did you come back?" The security captain frowned: "Let's take a look at the surveillance at the gate of the community."

"Let's go." Jiang He said, "Together."

Everyone followed behind the security captain, and Shao Lao asked, "Did you find anything?"

Jiang He shook his head and said, "I'm just calculating the probabilities, I'm trying to figure out the probability of impossible or possible occurrence. There are only three access cards, and I have found four possibilities. The murderer stole the access control of Ge Dongyun or Ge Dongai. Card. Second, Ge Dongyun left home today and came back, third, Mother Ge came back, fourth, Ge Dongai came back."

"The fourth point is almost impossible. We can't investigate the second point." Jiang He said, "So we have to focus on the first and third points."

Shao Lao nodded, he thought for a moment, and then said: "From the first point of view, Ge's mother's access control is stuck in our hands, so it is not lost by Ge's mother. If Ge Dongyun lost it, the murderer will take it after killing. It is also possible for Ge Dongyun’s access card to be placed in the house, if Ge Dongai also has one in his hand, then we must consider the other possibilities.”

During the conversation, several people have come to the door guard.

The surveillance video was transferred, and the video showed that at 8:36, Mother Ge's car drove into the community. During this period, Mother Ge rolled down the window and greeted a security guard. In other words, during the period of Ge Dongyun's murder, Mother Ge was still outside and had no time to commit the crime.

"Does she drive to drop off the child every day?" Shao Lao looked at the security captain.

The security captain shook his head and said, "That's not true. This Ms. Wang's son goes to the nearby bilingual kindergarten. We are in the school district. We are close to the kindergarten, primary school, and middle school, so hurry up. It’s seven or eight minutes. Usually she drives the kids when it’s raining, but occasionally she drives elsewhere.”

The security captain added: "Ms. Wang and we are relatively familiar, because they are about the same age, I heard that she often goes swimming, or does fitness yoga, so she is in good shape..."

Having said that, the security captain knew that he was a little rude, and said, "Cough, that's all I know, I don't know the rest."

"But today, after she delivered the child, she went to the vegetable market and drove back. She didn't go anywhere else." Mr. Shao said again: "Is the vegetable market far away?"

"It's not far!" The security captain said again: "Our community is good because it's not too far from anywhere. The vegetable market is in front of the kindergarten, drop by. If you walk for a while, the subway is not far away. If you Go there, there is a big square there, watching movies, singing, eating, etc. is a one-stop service."

While talking, a car came to the door. The security captain looked at it and said, "Isn't this a coincidence? Isn't Ms. Wang back."

With that said, the car window came down, and it was Mother Ge.

Mother Ge's expression was still gloomy, she nodded at a few people, and drove into the community.

The task force didn't say anything to Mother Ge, but just watched her car leave.

Jiang He said, "If it only takes ten minutes to walk, Mother Ge also has time to commit the crime."

"But she's shopping at the vegetable market," Yuan Jun said.

Shao Lao nodded and said slowly: "But the more perfect evidence of alibi, the more suspicious it is. She drove away with a big goal. When she came back, she said hello to the security guard, which strengthened the concept of alibi time. And she sent a text message before and after Ge Dongyun's murder."

"She has the time to commit the crime, but she doesn't have the time to commit the crime." Mr. Shao said again: "But there is the most critical issue, the motive."

Yuan Jun agreed with Shao Lao's words, he said: "Yes, we have visited Ge Dongyun's house several times, and I found that Ge's mother is very kind to Ge Dongyun, even a little too kind, but this also makes me have a kind of opinion. The feeling of not coming out, that is, it just feels awkward.”

"That's right." Shao Lao said: "What you said is very important. It's awkward, very awkward."

At this moment, Xu Yiman's call reached Jiang He's cell phone.

"What's the result?" Jiang He went straight to the point.

Xu Yiman said: "The detailed autopsy results have come out. The cause of death is the knife that pierced the heart. Since the time of death is very short, I have accurate the time of death to within minutes. Ge Dongyun died at about 8:20. Between two and eight twenty-six."

"Eight twenty-two to eight twenty-six?" Jiang He nodded and said, "Go back to the police station first, we'll go back right away."

"Okay." Xu Yiman nodded.

"The time of death is between 8:22 and 8:26." Jiang He said to several people.

"This time is about the same as what we guessed." Shao Lao said: "But the most urgent task is to figure out how the murderer turned that bedroom into a secret room."

Jiang He looked at Lao Shao: "I've already guessed that eight to nine are close to ten."

"Secret room?" Shao Lao and Yuan Jun looked at Jiang He and asked in surprise.

Jiang He nodded and said slowly, "Yes, I already know how the secret room was formed. When you were dealing with reporters, I climbed up to the second floor by myself. On the window edge of the second floor, I saw Going to the bedroom, at that moment, I understood how the murderer did it."

"What did you see?" Yuan Jun asked.

"A messy house." Jiang He replied.
