Xu Rui pondered: "Are you sure that this single man has no possibility of returning to Qingshi's house during his business trip?" ”

"What we investigated for this single man...... I almost didn't count how much hair he had. Wu Dafang exaggeratedly said: "He really didn't have the time to commit the crime, because he arrived at noon on the 28th, and on the 29th, 30th, and 31st, he always ate, lived and worked with the people of the branch on the other side, took the train back to Qingshi in the early morning, and returned home in the afternoon." We also compared his DNA with the fluid extracted from the sisters' bodies, and it was different. Oh yes, the fluid on the bodies and bodies of the deceased is all one person, in other words, it is not clear how many people are the murderer, but there may be only one person who committed the assault, unless the other party has taken protective measures. ”

Xu Rui nodded and said, "We have taken this case, let's take all the information of the case." ”

Wu Dafang frowned, turned around and went out for less than five minutes, and brought a bunch of materials, including a description of the case, pictures of the scene, and several evidence bags, which contained a man's hair extracted from the scene, as well as the rope that bound the deceased's sisters, their mobile phones, wallets, documents, and bank cards.

"Didn't even get a fingerprint?" I was surprised: "This murderer is professional enough." ”

Wu Dafang nodded and said, "You guys look at it first, and if you have anything to ask, call at any time." With that, he pushed the door open and left.

Xu Rui and I picked up the materials and read them first.

The names of the deceased are: Yu Xiaochun (25 years old), Yu Ziyu (27 years old).

The sisters are of medium appearance, have a good figure, and work in the same company. What surprised us was that the company that Yu Xiaochun and Yu Ziyu worked for turned out to be the cultural company that Ye Mei opened in the Xingu Building!

It was Ye Mei's employees who died?

Yu Ziyu and Yu Xiaochun's family is from Anhui Province, so they are renting houses in Qingshi, with a monthly salary of six or seven thousand, and the bonus is calculated separately. At present, Yu Ziyu and Yu Xiaochun are both single, the elder sister broke up with her boyfriend four months ago, and the younger sister has not been in a relationship for two years.

March 27th and 28th are Saturdays and Sundays, and they are double holidays. However, the sisters are still working with the rest of their colleagues, because that week, Ye Mei's company has an urgent business, so the employees are on vacation, and in this way, the sisters have a break on Monday and Tuesday on the 29th and 30th.

When I went to work on Wednesday, the company found that the Yu sisters did not come, so they called to ask, but found that they could not be contacted. Ye Mei was very worried, she asked the two employees to go to the Yu sisters' house to look for it, but learned that they couldn't knock on the door, because they lived on the first floor, the two employees went to observe the windows one by one, and the curtains were not closed, which means that the Yu sisters did not come back last night or got up early this morning and left.

Ye Mei asked the employees to go to the surveillance, and the Yu sisters went out together on Tuesday morning and did not go home again.

Ye Mei immediately called the police, but the sub-bureau never found out the final whereabouts of the Yu sisters, and only found through road monitoring that the Yu sisters took a taxi to the bustling city center on Tuesday morning, and they couldn't be locked down after shopping.

Not only that, the police contacted the parents of the Yu sisters, and the other party said that the daughters called them at noon on Tuesday and said that they would go home to see them in another month until May Day.

It can be seen that the Yu sisters' flowers disappeared after noon on the 30th. It took two days for the sub-bureau to have no clues, and Yu Xiaochun's mobile phone did not have any communication records after calling his father's number at noon on the 30th, and Yu Ziyu did not have any phone calls or messages since the morning.

In this way, on the afternoon of April 1, Xie Ming, a single man, came home from a business trip, and when he took the key to open the door, he found two female corpses on the ground and on the bed, and he was scared to death, and he called 110 in a panic.

Wu Dafang's team dispatched the police, and through the information on the mobile phones and ID cards left by the deceased, they connected with the disappearance of the sisters two days before the substation.

How did Yu Xiaochun and Yu Ziyu appear in Xie Ming's house?

Wu Dafang investigated the scene and found that the murderer entered and exited Xie Ming's residence through the window.

Xie Ming is a rented house, located in Hualian Village, next to the national highway, and commutes to work by bus every day. There are many factories next to this Hualian village, so most of the houses in the village are rented out, and there are only cameras at the end of the main road and in the middle of the main road. Xie Ming lives in a residential area in the southeast, with staggered alleys and a dead river on the edge, so there is no monitoring for Wu Dafang to check.

According to the forensic examination, the time of death of the Yu sisters was between 3 and 5 a.m. on April 1, and they had not eaten or drunk for at least 36 hours before they died.

The cause of their death was suffocation, with obvious pinch marks on their noses, and the murderer should have choked their noses so hard that they could not breathe and died.

Wu Dafang relied on this murderer to take advantage of Xie Ming's absence to bring the Yu family sisters to his house to commit the crime, and it was very likely that Xie Ming's acquaintance committed the crime, so he investigated all the people in Qingshi who knew that Xie Ming was on a business trip, a total of twelve, most of them were colleagues and bosses in the company, but the DNA samples of these people were collected, and compared with the DNA extracted from the deceased, none of them were consistent.

This made Wu Dafang have no choice, and he could only pin his hope on the monitoring of various intersections leading to Hualian Village, but there were too many vehicles and pedestrians passing by, and it was not practical to check them one by one. Moreover, in the past few days, even if the owner's vehicle is found, depending on the professionalism of the other party, all the traces on the car have already been wiped clean.

Did the perverted murderer know Xie Ming, or did he know the Yu family sisters, or was he a stranger who had nothing to do with either party?

How were the Yu sisters brought to Xie Ming's house?

There are a lot of questions in our minds.

Wu Dafang's team investigated for three months, and the case was shelved without any progress, but recently, the family of the deceased came all the way to the Qingshi Police Station to inquire, and Wu Dafang told the truth about the investigation. The Yu family's parents left the police station in grief and went to the viaduct not far away, climbed up and wanted to die, but fortunately they were rescued in time, so that no tragedy happened.

When the head of the bureau heard about this, he felt that the Yu family's parents were too pitiful, so he asked Wu Dafang to pick up the case again, and if it couldn't be solved in a week, he would throw us A7.

After reading it, Xu Rui and I handed the information to Ye Jia, the living dead, and Li Yuan, and after half an hour, they also finished reading it, and they all said that they were helpless.

The living dead said half-jokingly and half-seriously: "Team Leader Xu, you picked up a hot potato this time." ”

"Alas...... Is it easy to raise a pair of daughters? If I were the parents of the deceased, I would definitely want to have the murderer torn to pieces. Xu Rui sighed slightly and said, "Since we have taken this case, let's go all out!" Put aside the poison king and the carrion for the time being. ”

"The parents of the deceased should still be in Qingshi." Xu Rui instructed: "Ye Zi, little worm, give you a task, let Wu Dafang take you to find the Yu family's parents, appease them, stabilize their emotions, and don't let them have the idea of seeking death again." ”

"Yes."

Ye Jia nodded, and he and Du Xiaoworm left.

"Ah Li, Lao Huo, Xiaochen, let's go to Ye Mei's cultural company, visit the colleagues in front of the Yu family sisters, and have a better understanding of them." Xu Rui took the car keys and said, "On the way, you call Lao Hei again, ask him to give the phone to Ye Mei, and you can talk to her about the Yu family sisters." ”

We immediately set off, got into the car and went to the Xingu Building, on the way I dialed Lao Hei's number, no way, Ye Mei is neither a member of the Ninth Bureau nor a family member, and no tools are allowed to contact the outside world, so it can only be like this. But Lao Hei answered the phone and said that Ye Mei didn't sleep much last night and was resting now, so I hung up the phone and planned to ask later.

I reviewed the case in my mind, and my mind moved, and said: "Boss, I think we should change the direction of investigation, because about the circle of the Yu sisters, Wu Dafang has checked everything that should be investigated, and there are no major clues for us to go." ”

Xu Rui slowed down the car and asked, "Which direction to check?" ”

"This murderer dared to leave the essence containing DNA, but he didn't dare to leave any fingerprints." I said thoughtfully: "So, he knows that his fingerprints are recorded in the system, but the DNA has not been collected, and the methods are brutal and extremely professional, the other party must be a habitual offender, and he has been arrested and imprisoned in the early days!" ”
