Through the surveillance, it can be seen that Liu Yingying left the Night Heaven KTV alone at 11:15 that night.

By the time she left, she was already in a state of drunkenness.

Just as she disappeared from the surveillance range, a flash of light suddenly appeared on the road, which was emitted by the car alternating its high beams.

Immediately afterwards, a car pulled to the side of the road, slowly drove in the direction that Liu Yingying left, and finally disappeared into the surveillance video.

Lu Ke clicked the space bar, and the picture froze in the last moment before the car left.

Because of the monitoring angle, Lu Ke couldn't see the license plate number of the car, he could only see that it was a black car, and the specific car model had to be compared according to the body shape.

"Black sedan! The body shape seems to be, too! Mo Yufei was very excited and shouted directly.

Lu Ke nodded, and he was also very excited, "Take the photo back and determine the model of the car." ”

No matter what Lu Ke said, Mo Yufei had already decided that the sedan was the painted taxi: "Although the surveillance video did not capture the things in the back, from the perspective of the car's flashing lights and driving, he was running for Liu Yingying." It is very likely that Liu Yingying was killed after taking this car home. ”

What Mo Yufei said is not wrong, Lu Ke also thinks so in his heart, but the current clues cannot constitute a complete chain of evidence, unless everything is behind the perfect coincidence.

First of all, the murderer needs to know all three female deceased, and they all have a very good relationship.

The second is that after killing Yuan Dongni, the murderer modified the body color of the taxi, and did not immediately go to Lehua County to sell the stolen goods.

The last and most important point is the motive for killing.

The first two deceased in this case, Miao Junmei and Yuan Dongni, were both car drivers, while the third deceased, Liu Yingying, was not only not a driver, but also did not even have a car.

In other words, if it is determined that it is a serial homicide case, then the murderer's motive for killing is different.

The first two murders and body dumping cases can be characterized as murders carried out by the murderer against a female driver, so what was his motive for killing Liu Yingying?

"Record the relevant information of Du Ge and Luo Luo, and go back to investigate their relevant information." Lu Ke said lightly.

Mo Yufei nodded, recorded all the information, and made a copy of the surveillance video.

Later, Lu Ke briefly investigated Liu Yingying's work here with Fu Zhuojun, the manager of Night Heaven KTV, whether she had any enemies and who she had recently had conflicts with.

But none of them got any valuable clues.

Looking at the figures of the two leaving, Fu Zhuojun breathed a long sigh of relief, turned around and ran into the box, and made a call to Director Li.

At present, the scene investigation of the burglary and homicide case in Anzhu Town has come to an end, and everyone has returned to the Jing'an City Public Security Bureau to quickly carry out the autopsy and trace examination.

As soon as Lu Ke walked into the office of the criminal police team, Su Simeng brought him an important clue.

"Team Lu, at noon today, a black sedan drove into Lehua County, and it used a deck." Su Simeng handed a surveillance video photo to Lu Ke and said excitedly.

"The murderer really drove to Lehua County to sell the stolen goods." Lu Ke looked at the photo in his hand, and his heart was full of joy: "In the end, it still shows the horse's feet." ”

Su Simeng was also very happy, which showed that he had not wasted a day watching the surveillance video.

"Can you continue to track this car?" Lu Ke looked at Su Simeng and asked in a deep voice.

"The trajectory of the vehicle is already being investigated, and there will be clues soon." Su Simon said seriously.

……

A few hours later, in the office of the criminal police team, a case analysis meeting was held on the serial murder case.

Everyone summarized all the clues and made a plan for the arrest.

At the meeting, Mo Yufei brought a key message.

"Luo Luo, formerly known as Quan Yuantong, a native of Anzhu Town, is the best friend of the deceased Liu Yingying, and was introduced by Liu Yingying to Night Heaven KTV half a year ago to do wine sales and serve from things.

Du Ge, formerly known as Du Feiyu, a native of Anzhu Town, a contractor, is a frequent visitor to Night Paradise KTV, and met Liu Yingying. Later, after Liu Yingying's introduction, I met Quan Yuantong, and at present, Du Feiyu and Quan Yuantong are lovers.

And when I investigated the information of Quan Yuantong and Du Feiyu through the internal network of the Public Security Bureau, I found that Quan Yuantong's name appeared in a traffic accident case. ”

None of the people present spoke, listening to Mo Yufei continue: "Three years ago, Quan Yuantong and her boyfriend Yan Xingfa encountered a car accident on the way home, and the cause of the accident was a female driver's improper operation and mistaken the accelerator as a brake, resulting in Yan Xingfa being hit and breaking his leg. At that time, the public security bureau and the traffic police team were all involved in the investigation of the traffic accident, and finally the two parties reached a settlement, and the female driver bore all the costs of Yan Xingfa's treatment, and then carried out the corresponding civil compensation. ”

Hearing this, Lu Ke immediately became alert and asked seriously, "Is there a photo of Yan Xingfa?" ”

Mo Yufei nodded, pressed the mouse, and a photo appeared on the big screen.

The moment the photo appeared, the office exploded instantly.

Because the photo of Yan Xingfa is exactly the same as the photo in the surveillance video of the car repair shop in Anzhu Town.

Everyone was extremely excited and excited, Ling Zizhen slapped his face even more, gritted his teeth and said, "I finally found you." ”

Mo Yufei cleared her throat and analyzed: "Yan Xingfa is currently suspected of committing a major crime, everything about this serial murder case stems from the car accident three years ago, because Yan Xingfa was hit and broke his leg, so his heart is full of hatred for female drivers." Then his girlfriend Quan Yuantong was introduced by Liu Yingying to work in Night Heaven KTV, and was raised by Du Feiyu, so Yan Xingfa held a grudge against Liu Yingying and took revenge and killed him. ”

After listening to Mo Yufei's analysis, Lu Ke added: "This is a gang crime, Yan Xingfa must have a stable channel for selling stolen cars." ”

At this time, Su Simeng took over and spoke at the right time: "According to the tracking investigation, the black fake car drove to a second-hand car trading market in Lehua County. After investigation, it was determined that the boss's name was Lu Gaoshuang. When the first case happened, we investigated the second-hand car trading market, but we didn't find any clues, Lu Gaoshuang must have known that Yan Xingfa's car was coming from the wrong way, so he deliberately didn't let us find out. ”

Lu Ke settled down and asked Ling Zizhen, "Is there any problem with the trace examination department?" ”

"There is no problem, the scenes of the three crimes are highly consistent, and the murderer did not leave any key clues." Ling Zizhen replied.

Lu Ke looked at Jiang Xiran again: "Is there any problem with the forensic department?" ”

Jiang Xiran shook his head: "There is no problem with the forensic doctor, the strangulation marks on the three corpses are the same, and the murderer is the same person." ”

Lu Ke stood up, propped up the table with both hands, leaned forward, and said sharply: "Apply for an arrest warrant, arrest someone." Secretly arrest Lu Gaoshuang, don't startle the snake, Yan Xingfa has three lives on his back, there must be a hiding place, and Lu Gaoshuang must know where Yan Xingfa is hiding. ”
