In addition to us, Team Xiao also went to the technical department. Shi Hao saw that all of us had arrived and displayed the information with a projection. "I missed a very important piece of information when I checked his family information just now, that is, Song Ke's biological father. We know that blood type A and blood type O cannot give birth to children with blood type B, so who is Song Ke's biological father. So I checked the previous information of Song Ke's mother, although there was no police information, but I checked the police cases in the year before and after to see what I found. Shi Hao changed a page.

"Isn't it a novel?" Team Xiao glared.

Shi Hao hurriedly explained: "It's a novel, it's a documentary novel, based on all kinds of cases encountered by the police station in the past 50 years, and it can be regarded as the autobiography of the old-timers in the police world." I just went to confirm with this old-timer, and although the name is different, the case he wrote is indeed true. ”

Shi Hao turned on the recording, and a thick but slightly hoarse baritone appeared: "The case you said was closed 35 years ago, and the murderer who was arrested in the end surprised us all, his figure was like a pockmark, and his face was like a scholar, I didn't expect to kill so many girls." By the way, he did have a subject at that time, and when we went to catch the murderer, his subject had a big belly and looked like he was about to give birth. I didn't know how to talk to him about it, and I was afraid that something would happen to her when she knew that her subject was a murderer, but to my surprise, he was very calm after listening to our narration, and said to us 'got it' flatly. We guessed if it was their 'husband and wife' who joined forces, but the pregnant woman had a perfect alibi, and we couldn't arrest her. She had never come to visit the murderer, and not long after the accident the girl had quietly moved away on her own. ”

Shi Hao turned off the recording: "I went to the archives to check the case file of that year, because the murderer tried to commit suicide in prison back then, so there happened to be a medical record to provide us with his blood type, type AB, Song Ke's mother is type A blood, if you conclude that the murderer is Song Ke's father based on this alone, it must not be established, but the old-timers also mentioned just now that they also investigated the murderer's girlfriend at that time, so there are still investigation records, Wang Xiaoli of the Fifth Cotton Spinning Factory is also Song Ke's mother." Judging from Song Ke's birthday, the date of his birth happened to be the 4th month after the murderer was caught. Now it is basically confirmed that the father who sent off the guest was the murderer of the year. went to check the admission records of the send-off guests, Song Ke's household registration has been filed at his grandmother's house, and he returned to his home after junior high school. Song Ke studied in elementary school near his grandmother's house, and when he was in junior high school, his grandmother died of illness and went to the school near his home. ”

After listening to this, Li Jing asked Shi Hao: "Can you find out his father's modus operandi?" ”

Shi Hao turned another page: "This is what I often call a genetic coincidence, the object of his father's choice to kill is a woman with long flowing hair, and the victim is basically a death in a short period of time, and the murder weapon is a watermelon knife." His father liked to braid the hair of the victim after he killed him, and he would also pose for the victim when he buried the body - as if the victim was just asleep. ”

"Our cases now look very similar to those of the past, they are all victims with fixed characteristics, and the methods of killing and the form of disposing of corpses are similar." Team Xiao looked at the information on the big screen, and then turned his eyes to the four victims listed on the display board.

Teacher Lu took off his glasses and looked at us: "Some researchers have studied the relationship between genetics and crime before, and they speculated that fathers who have committed crimes will pass on certain factors to their children, which in turn increases the likelihood that their offspring will engage in criminal behavior. Although there is no argument whether Song Ke's crime was influenced by his father's genetics, we can use it as a reference number, but it is completely impossible to prosecute him in the future based on speculation. But another point mentioned by Shi Hao is very helpful for our family's investigation. Shi Hao mentioned before that Song Ke only returned to his home after junior high school, and this was not out of his original intention, Shi Hao mentioned that Song Ke's grandmother had just died during that period, and Song Ke would go to his home to establish a new connection. But this connection was not due to blood relations, but out of necessity. Song Ke was three years old when his mother married someone else, and for Song Ke, who had lived with his grandmother since he was a child, he was just sent to a foster family. Crowe, who has studied whether the children of offenders can be influenced by adoptive families, found that the older the offender children are at the time of adoption and the longer they are in temporary foster care, the more likely they are to develop antisocial personalities in the future. And Song Ke's situation fits all the characteristics, you see that he was taken into the new 'adoptive family' by his mother when he was a teenager, and stayed there until he was 23 years old and went abroad to study. We don't know what happened next, but I believe it was this adoption experience that had a bad influence on what he is doing now. Shi Hao, did her mother have her own children later? ”

Shi Hao nodded and tapped on the keyboard: "Yes, but it's still a boy." However, the father in the legal sense also brought a girl, who was the same age as Song Ke. Ah, I see. Shi Hao's exclamation made us move our eyes from the projection to him.

Shi Hao switched the projection interface to his notebook: "Look here." He highlighted a passage with the mouse, "The date of this girl's death was in the spring of six years ago. Looking at our 4 victims and the current missing, the accident happened in the spring. Here is a picture of the girl. "A brown-haired girl appeared on the screen, and the picture of the victim was on the display board, each with the girl's shadow.

"What was the cause of that girl's death?" Team Xiao asked anxiously.

"The car accident caused a bleeding in his internal organs and died on the way to the hospital." Shi Hao called up the last piece of information.

"Print out the girl's photo, Mr. Lu, you still have to go to the interrogation room with me." Team Xiao glanced at Li Jing, "Li Jing, you." ”

Li Jing took over the conversation directly: "Let's go to check Song Ke's usual movement trajectory and analyze the possible places where the missing person is hidden." ”

"Please, you two, we don't know the status of the missing person now, in order to buy more time for rescue, you two must quickly find out where to hide." After speaking, Team Xiao and Teacher Lu quickly walked in the direction of the interrogation room.

I called up the satellite image, and Brother Shi Hao called up all the usual consumption records of the send-off. Li Jing stood behind the two of us: "Xiaozhi, you go and find the community on Wutong Road that has no monitoring equipment." Shi Hao, find out Song Ke's consumption records within 5 kilometers near Wutong Road. ”

I clicked on the cell information that appeared on the screen: "No, all the neighborhoods have CCTV cameras installed inside." ”

"Don't worry." Li Jing comforted me, "Are there any vacant buildings on Wutong Road outside the public monitoring area?" ”

"New community?" I asked as I checked.

"It's not." Li Jing denied my idea, "Is there a ghost building over there?" ”

"Haunted building?" I was taken aback.

"Only the noise there doesn't make people suspicious, does it? Or a haunted house? Even if there is surveillance, it doesn't matter, it is to be able to trick the victim into entering the house, and no one will suspect anything else. After Li Jing explained to me, she turned her head and asked Shi Hao, "Have you found out where you consumed?" ”

Shi Hao sent me the information, and I listed all the buildings that could be related to the supernatural events on Wutong Road, and compared the consumption records that Shi Hao called out, and finally locked the two places. The first is a house in Building 3 of Wutong Road Community, and the other is an old building on Wutong Road that has been demolished to half of it, and I don't know why the construction team evacuated after it was demolished halfway, and it is rumored that it is haunted. According to Song Ke's bank card consumption records, he spent money near these two buildings.

Li Jing pointed to the haunted house in the Wutong Road community: "Let's see if there is any rental information for this residence." ”

Shi Hao inserted ** on the internal information network of the housing management office, and I searched for leasing news on various intermediary websites, and finally settled on a leasing website. Shi Hao called the head of the household but found that the phone was not in the service area. I called the agency to confirm that the house was confirmed for rent. However, because it was a situation many years ago, the agency could not provide tenant information immediately.

"Shi Hao, directly connected to their backstage, began to check tenant information six years ago." Li Jing didn't wait for me to hang up the phone before he spoke directly. Ancestor, everyone on the phone heard it, and she was angry. Before the person on the phone could speak, I hung up decisively.

Li Jing's analysis is correct, this room has only been rented by Song Ke alone, and the initial date of renting it was in the spring of 5 years ago, 1 month before the death of the first victim.

Li Jing informed the team of the situation by text message, and when he received the team's reply, Li Jing took me to the old building, while Shi Hao followed another team to the Wutong Road community.

Since we didn't have guns, we had to wait downstairs for the police. Shi Hao called: "Li Jing, the community here has been inspected, and the missing person Du Ting has not been found, but there are a lot of girls' clothes in this room, I don't know if it will be mixed with the relics of the previous victim." ”

"Bring them all back to the bureau and send them to the technical department for inspection."

A voice came over the radio on our side, too: "No missing persons found on the ground floor. ”

"Keep searching." Li Jing answered into the walkie-talkie.

"Could it be the basement?" I looked at the building and suddenly thought, "Although there is no underground garage in this old community, the basement is inhabited by users." And halfway through the demolition, these brick building materials almost buried the entrance to the basement, but as long as you clean it up a little, you can still find a path that is not particularly obvious. I once read a lot of reports that some wanderers would go to the basement of an abandoned building to spend the winter, and if it was a sound coming from the basement, and everyone didn't know about it, they would mistake it for a ghost's voice when they couldn't find the source of the sound on the ground. ”

Li Jing picked up the walkie-talkie: "Let's see if there is an entrance to the underground near the first floor, the missing person may be hidden underground." ”

Ten minutes later, the radio heard again: "We found the missing person in the basement, there are signs of dehydration, call an ambulance immediately." ”

When Du Ting was carried out of the ground by the medical staff, I hugged Li Jing beside me: "Great." ”

Li Jing smiled and touched my head, and dialed Du Tao's phone: "Your sister is saved." ”
