Street Park.
When Han Bin arrived at the scene, a cordon had been pulled up around him.
There are many morning exercisers watching outside.
Zeng Ping, Li Hui, and Zhao Ming have already arrived at the scene.
Han Bin looked around: "Captain Zeng, what's going on at the scene?"
"The victim Zheng Wen, 31 years old, is a teacher. She was jogging in a park in the middle of the street at around 8:30 last night when she was stunned from behind."
"Is this the location?" Han Bin compared the marked location.
Zeng Ping nodded: "She was dragged to the path next to the bushes, and then she was assaulted. She woke up at four o'clock in the morning and called the police."
"How is the victim?"
"It's okay, I asked Tian Li to take her back to the bureau."
"Has she seen the suspect?"
"The suspect should have been hiding by the bushes at the time. After she ran over, she was controlled from behind and fainted. She didn't see the suspect's appearance."
Han Bin thought for a moment: "Didn't you hear anything unusual?"
"She wears headphones and listens to music when she runs at night."
"Did the suspect leave any evidence?"
"On the victim's thigh, white genetic material and two unknown hairs were found, and they have been sent for identification," said Zeng Ping.
"That's how we all work together." Li Hui spread his hands.
"The DNA database can be compared with the best. If it can't be compared, we need to find other clues." Zeng Ping ordered: "Li Hui, you can ask the staff of the park and the people doing morning exercises."
"Zhao Ming, check the nearby surveillance cameras to see if there are any suspicious people."
"Han Bin, check the scene and see if there are any new clues."
"Yes." Everyone agreed.
…
Everyone split up and was busy all morning.
At two o'clock in the afternoon, return to the police office for a meeting.
Zeng Ping sat on the table: "Tell me, what have you found?"
"The victim has asked all the necessary questions, but her mood is still a little unstable. I asked her to rest in the reception room." Tian Li said.
"There are no obvious footprints at the crime scene, and there are no obvious signs of climbing around the park." Han Bin found no clues.
"What about surveillance?"
"There are surveillance cameras at the front and rear gates of the park. There are many people entering and exiting. It is very difficult to check their identities one by one. I have copied the surveillance cameras and can check them at any time." Zhao Ming shook the hard drive in his hand.
"Li Hui, how are you doing?"
"Team Zeng, most of the park's employees are off work at night. There are only two gatekeepers, and none of them noticed anything unusual," Li Hui said.
"Do the morning exercise crowd have any clues?"
"Morning exercisers and night runners are not the same group at all." Li Hui smiled wryly.
"That is to say, there are no new clues in the case." Zeng Ping frowned, and took out a box of Yuxi to distribute to everyone.
Han Bin lit a cigarette and took a puff: "Is there any news from the trace inspection? The DNA comparison has results, so there is no need to mess around."
"Tian Li, go to the trace inspection room and ask."
…
Not long after, Tian Li came back, followed by a man wearing glasses and a white coat.
"Yo, glasses, rare, finally willing to leave the laboratory." Zeng Ping laughed.
The man held up his glasses with his fingers: "Captain Zeng, I'm here to report the progress of the case to you. If you want to say that, I'll leave."
"Come back, I was joking with you."
The man nicknamed Glasses, named Lu Wen, is a technician in the trace inspection room and one of the few nearsighted people in the police station.
"The suspect did not leave much evidence at the scene. Only white genetic material and two hairs were collected. The genetic material has been extracted and sent to the DNA database for comparison."
Han Bin flicked the ash: "How did the suspect get stunned?"
"Ether."
Zeng Ping frowned: "Ether is controlled, where did he get it?"
"That's your job." Reuven shrugged.
Showing a look that has nothing to do with me.
"Have no valid fingerprints of the suspect been collected?" Han Bin asked.
"No."
"I asked the victim. When she was stunned, she felt that the suspect should be wearing gloves. As for the rest, she didn't know." Tian Li said.
Zeng Ping handed Lu Wen a cigarette: "How long will it take for the DNA comparison results to come out?"
"It's hard to say, it depends on luck, and it may not be successful." Lu Wen declined the cigarette: "Thank you, I quit."
"If you have any news, let me know as soon as possible," Zeng Ping said.
"Okay." Lu Wen responded and left the second office.
Zeng Ping stubbed out the cigarette butt: "Everyone has learned about the progress and clues of the case. If you have any ideas, you can share them."
"Ether is a contraband and cannot be bought in general pharmacies. The source of ether can be used as the direction of investigation." Tian Li suggested.
Zhao Ming went on to say: "You can continue to investigate and monitor. Those who appeared at the time of the incident and those who meet the conditions for committing the crime are all suspected."
"Visit the people exercising at night to see if there are any witnesses and new clues." Li Hui added.
Zeng Ping nodded: "The summary is good. The current investigation direction starts from these three points. If there are no other problems, we will start to assign tasks."
"Okay, you are waiting for us here." Li Hui smiled wryly.
"I will personally investigate the source of the ether." Zeng Ping glanced at the crowd: "You four check the surveillance during the day, and go to the park in the middle of the street to investigate and interview the masses at night."
Li Hui frowned: "This task is too heavy, how can I check?"
"The time of committing the crime was around 8:30 last night. After this time period, any men who left the park were suspected of committing the crime and were to be investigated," Zeng Ping said.
"Captain Zeng, I want to talk to the victim and see if there are any other clues," Han Bin said.
"Can."
Zeng Ping warned: "The victim has not recovered yet, let Tian Li accompany him."
"yes."
…
Qindao branch office, reception room.
"Crack..." There was a knock on the door.
Tian Li and Han Bin entered the reception room.
Sitting on the sofa was an intellectual woman with a dignified appearance and a well-proportioned figure, with tears still on her face.
"Teacher Zheng."
Zheng Wen raised her head, looked at Tian Li and Han Bin, and nodded slightly.
"Ms. Zheng, this is Police Officer Han from the criminal investigation team. He wants to ask you some questions." Tian Li made an introduction.
"what is the problem?"
Han Bin sat across from the sofa: "Mr. Zheng, do you often go to the park in the middle of the street to exercise?"
"yes."
"Do you usually go alone, or with friends?"
"not sure."
"When you were running the night before, were you ever followed or spied on?"
"No."
Han Bin continued to ask: "If you think about it carefully, do you have any other clues?"
"No, there are no other clues." Zheng Wen shook her head.
According to microexpression analysis, blunt repetitive questions are typical of lying.
Han Bin frowned. If the victim concealed clues, it would be very detrimental to the investigation.
"Mr. Zheng, do you have any new clues that you didn't tell the police?"
"I told the police everything I know." Zheng Wen leaned back, crossing her arms.
This is a typical mentality of defense and resistance. Han Bin is more sure that Zheng Wen has concealed the clues.
"I know this incident has hurt you a lot, and you may not want to recall it, but if you hide the clues, you will not be able to catch the suspect, and he will hurt others."
Zheng Wen closed her eyes, her expression changed again and again: "He took my underwear away."
