There's a point in the team

It didn't take long for the two of them to find Xie Zhihao's residence. When they reached the door, the tall criminal stood aside as a matter of course, and raised his chin to signal Qingming to knock on the door.

Although Qingming had a harmless smile on his face, he was slandering in his heart: "Heh... I have thought of the annoying things that disturb the people, didn't you think I was handsome and annoying just now?"

As a result, he pretended to knock for a long time, but there was no movement in the room.Qingming did not give up and continued to knock.Still muttering:

"Sir, your takeaway has arrived, and your hands are sore, please open the door to pick it up, thank you!"

"Go downstairs to the property in the community and ask for the landlord's phone number, and ask if the landlord has a spare key." As he spoke, Xing Zui put a grain of sugar into his mouth.

Qingming smiled bluntly, "Heh... I thought of running errands, didn't you think I was handsome and annoying just now?"

Of course, Qingming only dared to say this sentence in his heart.He looked at Xing Zui attentively, with one hand on his waist as if he was about to take something out, "Senior brother, I did some bad things that violated discipline, can you turn a blind eye and close one eye?"

Xing Zui lowered his eyes, and quickly glanced at the hand on Qingming's waist with a somewhat inquiring look, "You don't mean to... mark someone's door, right?"

"...I don't want to pee here if the fat water doesn't flow into other people's fields. I save it for our own toilet." As he spoke, the hand on his waist pulled something from his belt.Then he continued: "Go downstairs to look for business, then contact the landlord, and then ask the landlord to deliver the keys... At this rate, the food can't keep up with the heat, let alone find this Xie Zhihao. But now, I have a more convenient and effective method."

Xing Zui glanced at the thing in his hand, instantly understood his intentions, and showed an expression of disbelief, "You know how to open the lock?"

This question reached Qingming's heart, "Brother, I forgot to tell you that lockpicking is a unique skill in my private collection."

During high school, the dormitory where Qingming lived was patronized by a thief, and the moment she saw the pried lock hanging on the doorknob of the dormitory. It is "love at first sight" for the technology of 'unlocking'.

Since then, Qingming has been obsessed with the "technology" of unlocking locks.I spend time pondering the structure of various locks, studying the methods of unlocking, and even making the small tools for unlocking by myself.Up to now, ordinary locks can be opened by him in a few clicks.

Obviously, the lock on the door of the apartment where Xie Zhihao lived couldn't get into his eyes at all, it was really low-level pediatrics.But in order to show off in front of criminals, it's okay to spend this time pretending to be a B.

Qingming walked to the door, and in less than ten seconds, he heard a "click". Then, he raised his orchid finger and gently tapped the door... The door was opened by him so easily.

He turned around and saw that Xing Zui was looking at him with great interest, and a sense of pride surged in his heart... He made a gentlemanly gesture of "please".

"Qing three years old, you open the lock well, but it's a bit slow."

What Qingming is most proud of is this lockpicking technique. Hearing Xing Zui's words, he was naturally disdainful in his heart, and secretly said: "Compared with your stamina, of course it is slow." But he said: "I am not in front of senior brother.. .be restrained."

"That's right, this kind of technique, in the future, you can hide in the bed and show off yourself." Xing Zui walked into the room after speaking.

He looked at the house, Xie Zhihao rented a single apartment, there was a toilet and a simple kitchen as soon as he entered the door.There is a thin layer of dust on the stove, it can be seen that the people in the house usually do not cook.Walking a few steps inside, there is a sliding door. Xing Zui took out a pair of rubber gloves from his pocket, put them on, and opened the door. Because the curtains were drawn and the space was not very large, the room was very dark. .But under this dim vision, Xing Zui felt a taste of death.His gaze fell silently on a corpse on the ground.Xing Zui opened it and walked to the side of the corpse. Qingming walked in and saw this scene, his body was obviously taken aback.

"Call someone over"

Qingming quickly recovered, "Do you want to call an ambulance?"

Xing Zui got up slowly, "No need"

After speaking, he turned to look at a long low table next to the corpse. There was an empty glass on the table, and there was still a small amount of light pink liquid at the bottom of the glass.

The doors and windows are all locked from the inside, and the furniture and furnishings in the house are also unobstructed.A simple single bed similar to a university dormitory.A collapsible wardrobe, with two suitcases standing beside it, a computer desk with a yellowish top, and a long low table opposite, these are the few pieces of furniture in total.There was not much room left for walking, and Xie Zhihao's lying position took up a quarter of it.

An hour later, the outside of the apartment was cordoned off.Mu Sen's preliminary autopsy was basically completed, and Xing Zui came over after negotiating with his colleagues from the forensics department.

"What did you find?"

Mu Sen took off the mask, "The time of death was not more than 4 hours after the liver temperature test. There was blood in the mouth and nose of the deceased, and the blood was black. The preliminary judgment was that he died of poisoning. His clothes were messy and his palms were like clenched fists. In addition, the deceased's tongue was bitten by himself. The injury should have been caused by the pain and struggle when the toxicity broke out. The specific poison can only be known after going back for an autopsy."

------------------------------------

Xing Zui received an autopsy report from Musen before leaving get off work. The report showed that a large amount of tetramethylene disulfone tetramine was detected in the mouth and stomach of the deceased, which is commonly known as "rat poison".

The remaining liquid in the glass brought back from the scene also contained a large amount of "rat poison".

In addition, Xie Zhihao wore a watch on his wrist.After comparison, the crown that Xing Zui found in the dark alley belonged to this watch.And that key was the key to the rented apartment that Xie Zhihao lived in, and it only had Xie Zhihao's fingerprints on it.

First of all, apart from the traces left by Xie Zhihao's poisoning and struggle, there was no sign of fighting at the scene.However, the forensics department only detected the fingerprints of the deceased on the glass brought back from the scene. The tenant who lived next door was at home all day, but he never heard Xie Zhihao calling for help.

Furthermore, the water from the rat poison is light pink and has a pungent smell. Normal people would not drink this kind of thing unsuspectingly.

The above two points are enough to show that Xie Zhihao voluntarily drank that cup of rat poison.

Qingming turned the pen carelessly, and said, "Is Xie Zhihao committing suicide in fear of crime?"

Xie Xun said: "Whether he committed suicide in fear of guilt is still uncertain, but as far as we are concerned, even if Xie Zhihao survives, the current situation is not good for him."

At this time, Xing Zui who was sitting on the side spoke suddenly,

"it's not"

Xing Zui continued: "Currently we have no grasp of the key evidence that can prove that Xie Zhihao committed the crime. Although the crown found at the scene where Luo Xiaomei was killed belongs to Xie Zhihao, this alone cannot prove that he is '115 The female corpse case' and the real culprit who attacked Luo Xiaomei. In addition, it is strange that only Xie Zhihao's fingerprints were detected on the apartment key.''

Qingming and the others didn't notice this detail at first, but what Xing Zui said was unreasonable.

"Judging from the first case, the murderer is extremely cautious and has a strong psychological quality. He does not leave any clues after the murder, can avoid surveillance, and has certain anti-detection capabilities. In the second case, Not only did the murderer miss this time, but he also left a lot of clues, which is really abrupt. Are those clues 'accidental' or 'intentional'? They were left behind."

Xing Zui narrowed his eyes slightly while talking, and continued: "If Xie Zhihao is the murderer, why did he commit suicide before the police found him? Murderers who can kill innocent people are like cold-blooded animals. They have long since given up the sense of guilt. If It is said that the only thing that can move them in this world is his own life. Then how could he commit suicide so easily? Serial killers commit crimes to satisfy their morbid psychological demands, and only through continuous violence can they be satisfied, and now what happened In two cases, this is far from satisfying the murderer's desire to kill and sex|"

Qingming nodded, "Indeed, a serial killer usually kills five or six people if not more than a dozen or twenty. Xie Zhihao only killed two... No, to be precise, he killed one, it's not certain It's a serial murder case... It's like a joke after killing one person and then committing suicide."

Xie Xun: "That's the question again. If Xie Zhihao wasn't the murderer, why did he commit suicide so well? Do you think his life is long?"

Xing Zui crossed his hands and dragged his chin, staring ahead and muttering: "This is the first thing we need to figure out next. In the past two days, no matter what method you use, find out the information of everyone who has dealt with Xie Zhihao before his death."

Xing Zui knew in his heart that those hands hidden in the darkness must still be about to move.

-------------------

Two days later, the DNA report of the semen collected under Luo Xiaomei's armpit came out, and the semen under the armpit of the deceased Lin Lin in the "115 Female Corpse Case" came from the same person—Xie Zhihao.It's just that no one expected that it was originally a serial murder case, but after the second case, the victim would survive.Not only was Luo Xiaomei out of danger, but she also came to her senses.It's just because she was frightened to a great extent before she fell into a coma, she refused to approach anyone, and she couldn't communicate with others.Cui Jingfeng has been running at both ends of the hospital for the past two days, and the recording work he originally planned to do can only be temporarily put on hold.

Just when the case was at a standstill and deadlocked, another unexpected news was sent to everyone's ears.

Fang Lai sent Xie Zhihao's DNA to the database for comparison. The DNA comparison results showed that Xie Zhihao matched the DNA of the criminal who entered the house together with rape and murder eight years ago.
