The rest of the interrogation was similar to what Zhao Yu and the others had expected. Shortly after Xie Tongguo was fired, his father, who had been ill for many years, died of illness.
Xie Tongguo first gave his house to his uncle, then paid off his debts to other people. Then, he rented a small house in a remote place. At that time, he had 90,000 yuan left in his hands.
From then on, Xie Tongguo felt that the time was ripe, so he finally began his revenge plan.
As was the case, Xie Tongguo had carried out the murders according to the plot of the 11 Kills. At first, he killed the first victim, Zhan Jiankang, and the second victim, Hao Lili.
First, he followed the victims at night, and when he found an opportunity, he knocked them out with ether. After that, he used his electric tricycle to transport the victims to the crime scene that he had arranged beforehand. Then, he committed the murders, faked the suicide scene, and so on.
However, when it came to the third victim, Sun Peibin, Xie Tongguo, who was not very good at using electrical appliances, had an accident during the crime.
As Zhao Yu had expected, Xie Tongguo opened the door with the key that he had stolen from the intermediary company.
In order to make it look like the victim had broken into the house and committed suicide by touching the electric switch, he deliberately broke the lock. However, he did not expect that the electric switch would trip during the process of electrocuting Sun Peibin. Not only was Sun Peibin not electrocuted to death, but he was also woken up by the electric shock.
After Sun Peibin woke up, he recognized Xie Tongguo at a glance. Then, he had a fierce struggle with Xie Tongguo.
However, Xie Tongguo was young and strong, so he eventually knocked Sun Peibin out and electrocuted him!
After electrocuting him, Xie Tongguo was not sure whether Sun Peibin was really dead, so he stayed at the scene for more than two hours. It was not until Sun Peibin's body was cold that he hurriedly dealt with the corpse and left the scene.
In fact, Xie Tongguo knew that as soon as the police found Sun Peibin's body, they would immediately conclude that it was a murder. So, he thought that he should find another place to dispose of the body, or bury it or burn it.
However, as stubborn as he was, he still insisted on sticking to the overall plot of 11 Kills, so he would rather risk being exposed and leave Sun Peibin's body there!
However, what he couldn't figure out was that after waiting for more than half a month, there was still no news of the police finding the body!
Xie Tongguo was greatly surprised by the people's indifference. The room where Sun Peibin died was clearly occupied. It wasn't particularly cold at that time, and the body was smelly. The door was still open. Did no one find the body?
However, the reality was so cruel. No one found Sun Peibin's body! Of course, this was undoubtedly a good thing for Xie Tongguo.
Therefore, Xie Tongguo ignored Sun Peibin's body and began to plan his fourth murder.
As the saying goes, a fall into the pit, a gain in your wit. After deciding to freeze Pei Zhi to death, Xie Tongguo not only carefully inspected the scene, but also patiently observed Pei Zhi's every move in secret.
Finally, on a certain night, the perfect opportunity came to him. That night, the outdoor temperature in the Golden City had dropped to minus 17 degrees, but Pei Zhi was drinking with his friends in a tavern!
Feeling that this was a godsend opportunity, Xie Tongguo followed Pei Zhi, who had drunk too much. Just as Pei Zhi was about to go home, Xie Tongguo knocked him out with ether.
What happened next was much easier. Xie Tongguo just left Pei Zhi in the abandoned factory, and his murder mission was completed!
On such a cold day, Pei Zhi didn't even wake up before he was frozen to death on the spot!
In this way, the serial murder case of four people finally came to an end! However, looking at the cause and process of this case, it was thought-provoking.
Although Xie Tongguo had a serious psychological defect, as well as a lack of communication skills, if the people involved were less indifferent, less selfish, and more concerned about Xie Tongguo, perhaps this cruel serial murder case wouldn't have happened!
After the interrogation, Zhao Yu and the others all returned to the temporary office.
"Leader …" Wu Xiumin couldn't wait to tell Zhao Yu, "Just now, Leader Miao and I asked Xie Tongguo about Han Kuan. From his reaction, it seems that he really has nothing to do with Han Kuan!"
Miao Ying took a sip of water, then said, "Xie Tongguo said that since he sold the house, he has never seen Han Kuan and his wife again!"
Zhao Yu nodded, then asked, "That is to say, Xie Tongguo's case was purely accidental?"
"But …" Ran Tao scratched his head and said, "The timing of his crime is a bit too coincidental! It was just when Han Kuan was in prison as a suspect and was in deep trouble! "
Miao Ying then said, "To be honest, Xie Tongguo indirectly helped Han Kuan. If it weren't for Xie Tongguo, Han Kuan wouldn't have been able to invite our special investigation group here!
Ran Tao then said, "And, although Xie Tongguo talked a lot, in fact, he didn't help us at all! We were able to catch Xie Tongguo on our own! "
"Zhao Yu …" Miao Ying came up to Zhao Yu and said very seriously, "I think it's 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 were neighbors, so Han Kuan certainly knew about Xie Tongguo's death.
Miao Ying then said, "If Han Kuan knew that Xie Tongguo stole his 11 Kills and knew that Xie Tongguo had psychological problems, then … Could he have done something behind the scenes?"
Zhao Yu nodded, then said, "Well … Xie Tongguo's killing must have benefited Han Kuan the most! If he secretly guided or helped Han Kuan … "
Zeng Ke then said, "Leader … Don't forget Han Kuan's own case! If Han Kuan is really Xie Tongguo's guide, maybe his own case has something to do with Xie Tongguo! "
Wu Xiumin then said seriously, "But … From my professional point of view, Xie Tongguo is not lying. He really doesn't know Han Kuan! Think about it, Xie Tongguo has admitted that he killed four people, so it's impossible for him to cover up for anyone else! "
"Xiumin, have you ever watched Crime Scene?" Ran Tao then asked Wu Xiumin excitedly, "In that TV series, there is a masked mentor who specializes in setting traps for others and forcing them to kill people! What if Han Kuan is such a masked mentor? Or, did he use anonymous letters, the Internet, or some other special means? "
"Fool your head!" Wu Xiumin shouted. "When Xie Tongguo killed the last two people, Han Kuan was already in the detention center! What kind of guidance is that? "
"Um … This …" Ran Tao was speechless.
"Zeng Ke …" At this time, Zhao Yu suddenly remembered something, so he asked Zeng Ke, "Didn't the Longjiang Police Station send Zhang Jingru's original confession to us? What about the test results? Why haven't they come out yet? "
"Oh … Sorry, I forgot!" Zeng Ke slapped his forehead, then quickly took out a report and said, "Team Leader, the people from the Forensics Department have come just now. Look, their results are the same as my initial identification results. There are no traces of the confession being edited, and it was all done in one go! And, the voice is indeed Zhang Jingru's original voice! "
Wu Xiumin pointed to the whiteboard and said to Zhao Yu, "Leader, you can also erase the second part of the investigation! All three have been erased, and there is only one left! "
"Phew …" Zhao Yu put his hands on his waist and took a deep breath. Although he had already expected it, he still felt very dejected at the result.
