Han Bin listened to the recording several times. His hoarse voice seems to have been dealt with. He can't judge men and women from the voice alone, but he looks like a man from the tone of his voice.
"Creak..." Li Qin pushed the door and came in.
Bao Xing asked, "Sister Li, why did you go so long?"
Li Yuan's mother was too sad to walk down the stairs. She sat in the yard and cried for a while, holding my hand and saying a lot. Li Yuan was the lifeblood of the two.
Han Bin took out a pack of cigarettes and handed one to Li Qin. "Sister Li, it's hard for you."
Han Bin is not afraid of the hard work of handling a case. The biggest headache is facing the families of the victims. Their crying may delay the handling of the case, but considering their mood, they can't say hard words. They can only coax and persuade. It's a very patient work, and it's not easy at all.
"I'm used to it." Li Qin lit a cigarette and took a puff, "team leader, what new clues did forensic Li send."
Han Bin picked up the physical examination report, wanted to let her see, but think of this thing seems too hard, clearly is a word thing, do not study ten minutes to see.
"Further autopsy proved that Li Yuan was first corona by the murderer, and then strangled with a belt. After his death, he was invaded by his surname, and the man's genetic material was found in the victim's body."
Li Qin played the cigarette ash, "the victim has been corona, clearly can be directly surnamed invasion, why to kill after health?"
Bao Xing guessed, "will it be psychopathic? There are many similar serial killers abroad."
"Creak..." Wang Xiao and Jiang Yang came in when the door rang.
In order to compare the stadium monitoring with Skynet monitoring, the two went to the traffic police brigade.
Wang Xiao opened the door to the mountain road, "team leader, we have checked the monitoring of the stadium, focusing on the investigation of the monitoring from 9:30 to 10:12. After that, director Chen took people to the stadium, and searched the stadium, and found no suspicious people."
"During this period, there were three cars and four people left the stadium one after another. We cooperated with Skynet monitoring and intercepted several high-definition photos. The license plate numbers of the three cars could be seen clearly. But it is more difficult to trace the four pedestrians. "
Han Bin looked at the high-definition photos, a white SUV, a red car, a black car. Pedestrians are two men and two women.
"When did the victim Li Yuan enter the stadium?"
Wang Xiao looked at the notebook, "about seven fifty."
Han Bin asked, "when did these suspected vehicles and suspects enter the stadium?"
"SUVs enter the stadium around 3 pm, red cars enter the stadium around 6 pm, and black cars enter the stadium around 8:10 PM."
"As for the four suspects, only two of them have been confirmed to enter the stadium, and the remaining two have not been found. It does not rule out that they entered the stadium by car. "
Wang Xiao took out a photo, which was a man's photo, "among them, I think this person is the most suspect. At that time, I was checking the whereabouts of the suspect Li Yuan. As soon as Li Yuan entered the stadium, the man came in, and the two people were separated by less than a minute."
Han Bin took a look at the photo, "when did this man leave the stadium?"
"Ten in the evening."
Wang Xiao answered and continued, "if this person is really tracking the dead all the way to the stadium and killing each other in the swimming pool, I feel that she is likely to know the victim."
"Since this person has the sign of following, then continue to check Skynet to see if he is following the dead all the way." Han Bin suggested.
"We checked, but Li Yuan and the man are walking. If they don't pass the intersection, Skynet monitoring may not be able to find out. I think after daybreak, I'll check the private monitoring around the stadium, maybe I can find some clues."
Han Bin nodded, "yes, you continue to follow this line, as soon as possible to find out the identity of this man."
"Sister Li, contact the parents of the victims tomorrow and give them the photos of these suspicious people for identification."
"Good."
Han Bin continued, "for other people, we can't relax, especially these cars..."
"Creak..." A glottal sound interrupts Han Bin's words.
Ma Jingbo came in and yelled, "guys, mobile phone positioning is successful, ready to track the suspect!"
It's a surprise.
Han Bin asked, "Captain, where is the location?"
"At present, in the vicinity of Jinghua street and Chunfeng Road, the positioning target has been moving northward, and the speed is very fast. I think the suspect may be driving away from the city." Ma Jing wave path.
It should not be too late. Everyone should act separately.
Ma Jingbo stayed in the Municipal Bureau and was responsible for coordinating with the technical section and commanding.
At the same time, contact the team leader Ding Xifeng and ask him to mobilize the police to intercept the suspected vehicles.
Wang Xiao went to the traffic police brigade to check Skynet monitoring,
Han Bin, Li Qin, Jiang Yang and Bao Xing tracked the suspected target.Jiang Yang is in charge of driving, Han Bin is in the passenger compartment, Li Qin and Bao Xing are in the back row.
Bao Xing, lying on the front seat, said, "is the suspect careless? He was positioned by his mobile phone."
"The suspect has turned off his mobile phone. Maybe he thinks that the police can't find it. After all, not everyone knows that a mobile phone can be located when it is turned off." Li Qindao.
Bao Xing nodded, "that is, the suspect left his own genetic material, visible vigilance is not strong."
Jiang Yang said with a smile, "normal people don't kill people. Those who can do such things as killing people can't look at them in the eyes of ordinary people. "
Han Bin did not join the discussion of the three. He has been communicating with Ma Jingbo and Wang Xiao to determine the latest condition of the suspected vehicle.
Ma Jingbo is responsible for determining the general location of the car, Wang Xiao is looking for the car trace in Skynet monitoring, while Han Bin is tracking in the back.
After several comparisons, Wang Xiao finally found the suspected vehicle. It was a truck carrying sand. The car didn't drive fast and went north along Jinghua street.
Ma Jingbo has contacted the local police station and set up a stop on the road of the truck.
Ten minutes later, Han Bin received the news that the local police station had stopped the truck.
Fifteen minutes later, the driver of the truck was under control.
Another five minutes later, Han Bin took people to the scene.
There were two police cars and a truck loaded with idiots.
Several police stations around the police, there is a man has been controlled.
The police chief of the nearby police station is responsible for the interception task. Han Bin, on behalf of the second squadron of the municipal criminal investigation team, thanks each other for their assistance, and then took over the scene.
Han Bin looked at the suspect, about 40 years old, bearded, not tall, very stocky.
"Hello, I'm Han Bin from the municipal criminal investigation team. I'm investigating a criminal case. I'd like to ask you some information."
The man quickly stood up, "Hello, officer Han, my name is sun Jianzhong. I'm a truck driver. I just pull sand with the construction site. I haven't done anything illegal."
"You don't have to be nervous. We also do a routine inquiry." Han Bin looked at each other and asked, "how many mobile phones do you have?"
"Just one."
"Let me see."
Sun Jianzhong takes out his cell phone from his pocket and hands it to Han Bin.
Han Bin took a look, is a millet mobile phone.
"Are you sure there are no other phones?"
"No more."
"Where are you between nine thirty and ten twenty this evening?"
"As soon as I drove to the sand field, the workers were responsible for loading the sand, so I went to a nearby restaurant for dinner. Recently, I often went to that restaurant for dinner. The restaurant owner can prove it to me." Sun Jianzhong said.
"have you ever been to Wutong stadium?"
Sergeant sun shook his head. "No."
"Do you know Li Yuan?"
"Who?"
"Li Yuan."
"I don't know."
Han Bin doesn't see any sign of lying. He waves and asks Bao Xing, Li Qin and Jiang Yang to search the truck.
Li Qin searched the cab, Jiang Yang searched the bottom of the car, and Bao Xing searched the body.
Han Bin continued, "has your car passed by the Wutong stadium?"
Sun Jianzhong scratched his head. "Officer Han, I'm not from the city. I don't know where the stadium you said is. I only know how to get to several main streets."
Han Bin did not continue to ask. He went to one side to contact Ma Jingbo. According to the positioning of the technology department, the mobile phone was still, which means that the mobile phone of the deceased was in the car.
After a while, Bao Xing stood on the sand and cried, "team leader, I found an Apple phone, which is the latest model. It's probably the suspect's phone."
"Make sure."
"Yes."
"Jiang Yang, collect sun Jianzhong's DNA."
Sun Jianzhong showed a flustered color and explained, "officer Han, the mobile phone is not mine, and I don't know why it is in the car."
"You don't have to worry. The purpose of our coming here is to find out the facts and give you back your innocence."
