The subsequent interrogation was similar to what Zhao Yu and the others had expected. Soon after Xie Tongguo was dismissed from the unit, his father, who had been ill for many years, also died of illness.

Xie Tongguo first paid off the house to the uncle and relative, and then paid off the debts owed to others, and then rented a small house from a remote place. At that time, he still had 90,000 yuan left in his hand.

Since then, Xie Tongguo, who no longer has any fetters, feels that the time is ripe and finally starts his revenge plan.

Consistent with the circumstances of the case, Xie Tongguo completely committed the murder in accordance with the plot of Han Kuan's "11 Killings". At the beginning, the criminal process of his murder of the first victim Zhan Jianxing and the second victim Hao Lili was all very smooth.

He first followed his victim in the dark, and when he found an opportunity, he stunned him with a simple and crude ether method. After that, he used his passenger electric tricycle to transport the victim to the crime scene that he had already arranged, and then carried out the murder, and faked the suicide scene......

However, when it was the turn of the third victim, Sun Peibin, because he was not very good at electrical appliances, Xie Tongguo had an accident in the commission of the crime.

As Zhao Yu expected, Xie Tongguo stepped on it in advance and opened the door with the key he stole from the intermediary company.

In order to disguise himself as a deceased who broke the door into the house and then committed suicide by touching the electric door, he also deliberately broke the door lock...... However, he didn't expect that in the process of electrocuting Sun Peibin, there was a trip, not only did he not die of electricity, but he was woken up by electricity.

After Sun Peibin woke up, his reaction was quite fast, he recognized Xie Tongguo at a glance, and then he had a violent scuffle and fight with Xie Tongguo.

However, Xie Tongguo was young and strong after all, and finally knocked Sun Peibin unconscious, and reconnected the wire to electrocute him!

After electrocuting the person to death, Xie Tongguo was not sure whether Sun Peibin was really dead, so he stayed at the scene for more than two hours, and waited until Sun Peibin's body was cold, and then he hurriedly dealt with it, and then left the scene.

In fact, Xie Tongguo knew in his heart that as long as the police found Sun Peibin's body, they would immediately judge that it was murder. Therefore, it is safer for him to dispose of the body in another place, or bury or burn it.

However, he is stubborn, but he still insists on the overall plot of "11 Killings", so he would rather risk being exposed and still leave Sun Peibin's body there!

However, what made him unable to figure out was that he waited for more than half a month, but he did not find any news that the police had found the body!

People are so indifferent, which also surprises Xie Tongguo himself. The room where Sun Peibin died, obviously there were people living upstairs and downstairs, and it was not particularly cold at that time, the corpse stinked, and the door was still open, so no one found the corpse?

However, the reality is so cold, and Sun Peibin's body is really not found! Of course, this is tantamount to a good thing for Xie Tongguo.

Therefore, Xie Tongguo no longer cared about Sun Peibin's corpse and began to plan his fourth murder.

After deciding to freeze Pei Zhi to death, Xie Tongguo not only carefully inspected the scene, but also patiently followed Pei Zhi's every move in secret, and did not take the liberty of making a move.

Finally, one night, he waited for a perfect opportunity. On that day, the outdoor temperature in the Golden City at night had dropped to minus 17 degrees, but Pei Zhi and his friends drank a lot of wine in a tavern!

Sensing that this was a godsend, Xie Tongguo followed Pei Zhi, who had drunk too much, all the way, and just as he was about to go home, he used ether to stun him.

And then the rest is much easier. Xie Tongguo just abandoned Pei Zhi in the abandoned factory, and his murderous task was completed!

On such a cold day, Pei Zhi didn't even wait for himself to wake up, he was already frozen to death on the spot......

In this way, a case of murder by book that killed four people in a row has finally come to an end! However, looking at the cause and process of this case, it is thought-provoking and thought-provoking.

Yes, Xie Tongguo certainly has serious psychological defects and lack of communication skills, but if he ...... The parties involved in this can be less indifferent, less selfish, more concerned about Xie Tongguo, and more understanding, maybe this cruel murder case will not happen!

After the interrogation, Zhao Yu and the others all returned to their temporary offices.

Before the heel of the "Team Leader ......" stood firm, Wu Xiumin couldn't wait to tell Zhao Yu, "Just now, Team Leader Miao and I asked Xie Tongguo about Han Kuan, and judging from his reaction, he really has nothing to do with Han Kuan!"

"That's right," Miao Ying took a sip of water and said, "Xie Tongguo said that since he sold the house, he hasn't met Han Kuan and his wife again!"

"Oh......" Zhao Yu nodded, "In other words, Xie Tongguo's matter is purely accidental?"

"But ......," Ran Tao scratched his head and said, "The timing of his crime seems to be a bit too coincidental, right? Just in time for Han Kuan to be imprisoned as a suspect and in deep trouble!"

"To be honest, if you look at the results alone, Xie Tongguo can be regarded as indirectly helping Han Kuan, if it weren't for Xie Tongguo, Han Kuan would not have been able to invite our special investigation team over!

"Moreover, don't look at how energetic he is!" Ran Tao said unconvinced, "But in fact, he didn't help us at all!

"Zhao Yu ......" Miao Ying came to Zhao Yu and said very seriously, "I think...... It would be better to investigate this matter in detail! The biggest cause of Xie Tongguo's murder was his father's death. Han Kuan's father and Xie Tongguo are neighbors, and of course Han Kuan knows about Xie Tongguo's death......

"What if...... Han Kuan knew that Xie Tongguo had stolen his "11 Killings", and he also knew that Xie Tongguo had psychological problems, so ...... Could he have done something in the shadows?"

"Hmm......" Zhao Yu nodded and said, "Xie Tongguo killed people according to the book, and the biggest beneficiary is none other than Han Kuan! If he secretly guides or helps......

"Also, team leader......" Zeng Ke continued, "Don't forget Han Kuan's own case! If Han Kuan is really Xie Tongguo's mentor, maybe his own case will also have something to do with Xie Tongguo!"

"But ......," Wu Xiumin said seriously, "From my professional point of view, Xie Tongguo is not lying, he really doesn't know Han Kuan! Think about it, Xie Tongguo has already confessed his guilt and admitted that he killed 4 people, and it is impossible to shield anyone again!"

"Sister Wu, have you watched "Crime Scene"?" Ran Tao said to Wu Xiumin with a fluttering eyebrow, "In that TV series, there is a masked mentor who specializes in trapping others and then forcing them to kill......! Is Han Kuan also such a masked mentor, or is he through anonymous letters, the Internet, and other special means?"

"You're a big-headed ghost!" Wu Xiumin snorted, "When Xie Tongguo killed the next two people, Han Kuan was already in the detention center!

"Hmm...... This ......" Ran Tao was speechless.

"Zeng Ke ......" At this time, Zhao Yu suddenly remembered something and hurriedly asked Zeng Ke, "Didn't the Longjiang Police Station send Zhang Jingru's original confession a long time ago? What about the test results?

"Oh...... I'm sorry, I forgot!" Zeng Ke slapped his head, and hurriedly took a report and said, "Team leader, the people from the forensic department have already come here just now, you see, they are the same as my initial appraisal results, that confession has no traces of cutting, but it was done in one go! The voice is indeed Zhang Jingru's original voice!"

"That's right...... That ......" Wu Xiumin pointed to the whiteboard and said to Zhao Yu, "The second investigation content of the team leader can also be erased! All three are erased, and there is still one left!"

"Whew......" Zhao Yu pinched his waist with both hands and exhaled heavily. Although he had expected it, he still felt very frustrated to get such a result.

Because, as long as there is no problem with this confession, it means that Han Kuan can be acquitted! No matter whether he really killed his wife or not, he can still escape legal punishment!!
