Although this statement sounds very convincing, according to my years of experience, there is a high probability that homicide occurs between acquaintances, even if it does not occur between acquaintances, it is also caused by some kind of conflict, such as walking on the street and being killed by someone you don't know The incidence of this kind of case is very low and very low, and even if it happens, it may be a sudden psychosis of the murderer. www.biquge.info And things like buying murder are rare in reality, especially now that this kind of peaceful society under the rule of law has basically disappeared. Teacher Jin said.

"I also understand what you said, but now the murderer really hasn't surfaced, the people I can think of are not murderers, and those suspects who have been controlled, they can't control Wen Cheng when Wen Cheng dies, and no one of them can contact Fang Lu, who is this invisible murderer, I really can't figure it out now." Xu Tian said with a frown.

"The clues to the detection are back to the deceased, and if all the interpersonal relationships of the deceased are not broken, I am afraid that it will be difficult for the real murderer to emerge."

Buzzing......

Teacher Jin's mobile phone rang, it was Shang Shuai calling, and now whether it is Xu Tian or Teacher Jin, as long as they receive Shang Shuai's mobile phone, they will tremble a little.

The bad news is still coming, just now, the suspects in the hotel are jointly guarded by security guards, and each room is equipped with two security guards to guard one suspect, but something still happened.

One of the security guards guarding Li Tao went to the toilet, and the other went out to answer a phone, and when the security guard who answered the phone turned back to the room, Li Tao pinched his neck and fluttered on the floor, and the security guard quickly called Shang Shuai, but it was too late, Li Tao struggled a few times and died on the floor of the room.

Xu Tian returned to the hotel alone to investigate the scene, and Mr. Jin and Sitong stayed behind to protect Fang Zhen.

The scene was a mess, the quilts and sheets on the bed, as well as the pillows, all fell to the ground, according to the eyewitness testimony of the security guards, these were all knocked over by Li Tao himself.

Xu Tian inspected Li Tao's corpse, his lips were purple, his face was pale, and he looked poisoned.

There were two pinhole-sized wounds behind Li Tao's ears, as if they had been pricked by tiny needles.

The corpse had not yet stiffened, and the toxin was still spreading, and now Li Tao's entire neck had turned purple, and the toxin was still spreading further.

But now there is no forensic doctor, so I can only ask the doctor in the scenic infirmary to help take a look.

Li Tao had already lost his breath, and the cause of death was caused by the two pinhole-sized wounds behind his ears, a deadly toxin that took Li Tao's life.

The two security guards guarding Li Tao were isolated and questioned, both of them were very frightened, and they were both afraid of taking responsibility, and in Xu Tian's questioning, both of them seemed very scared.

In the end, Xu Tian didn't ask anything, there was a surveillance video in the hotel corridor, and the two security guards were indeed as stated in the confession, one was in a hurry to go to the toilet, and the other went out to answer the phone.

Xu Tian felt that this kind of thing should not be a coincidence, so he investigated the two dereliction of duty security guards.

The doctor examined the security guard, who was in a hurry to go to the bathroom, and found that the security guard had taken a large dose of laxatives, but the security guard himself did not know what food the laxatives were ingested.

The second security guard first received a text message that looked more ambiguous, and then about thirty seconds later, the strange phone call came in, and the security guard shyly walked out to answer the phone, but after chatting a few words, the other party hung up.

Sure enough, Xu Tian thought that this was a premeditated homicide, and the two security guards would definitely not walk out of the room for no reason.

And from this method of transferring the security guards, it can be concluded that the murderer must have been very clear about the character and personality of the two security guards.

The security guard who answered the phone should be the kind of person who likes to mess with flowers, otherwise most people will think that kind of strange text message is spam and ignore it, and there is a security guard who took a large dose of laxatives, this is definitely not a coincidence, someone must have deliberately made the security guard take laxatives.

But Xu Tian felt strange, even if the murderer could transfer the two security guards away from the scene of the crime, he would not be able to personally enter Li Tao's room to kill Li Tao! Because the camera in the corridor did not capture outsiders entering Li Tao's room, and the security guard who answered the phone did not go far, which was the door of the room where Li Tao died.

Judging from the surveillance video, the security guard who answered the phone paused at the door for about 20 seconds, then hung up the phone and stretched, staying at the door of the room where Li Tao was killed for about 50 seconds.

However, after the security guard turned around and returned to the room, Li Tao had already grabbed the things in the room, and at that time, Li Tao's lips had begun to turn purple, and his face was pale and struggling in pain in the room.

Who could be the person who could understand the personalities of the two security guards? What is the method of killing Li Tao?

There is no image of a stranger entering the room at the scene of the crime, so there are only two ways for the murderer to kill Li Tao, one is to remotely control Li Tao to stab himself like Wen Cheng. Although this method sounds like it can be implemented, Li Tao is different from Wen Cheng, because Li Tao has no reason to commit suicide.

Another way to kill Li Tao is to answer the phone, the security guard is the murderer, after the security guard who went to the toilet left, the security guard who answered the phone can stab Li Tao and then go out of the door to answer the phone, so it makes sense.

But no matter which method he used, Xu Tian felt that something was wrong.

First of all, he manipulated the killing, Li Tao was still seeking protection from the police the night before, and the cause of Wen Cheng's death had also reached Li Tao's ears, if the murderer wanted to use remote control to let Li Tao stab himself with a poisonous needle, such a method was very difficult to implement, and Li Tao had no reason to cooperate with the murderer to stab himself.

In addition, the idea of the security guard's murder is also a bit far-fetched, because although the security guard looks a little out of tune, but judging from his speech and demeanor, he is definitely a local young man with a low salary, the identity information of the security guard is very complete, and his age is not very old, so it is impossible to have anything to do with the case itself.

But even so, Xu Tian felt that the case still had to expand the clues from the two security guards, as long as he found someone who could know the two security guards so well, the case would have a very big breakthrough.

Soon, the appraisal personnel of the county police station rushed to the scene of the crime, and according to Xu Tian's request, the appraisal personnel found the two poisonous needles that took Li Tao's life at the scene.

After laboratory tests, the toxin on the poison needle is a chemical toxin, as long as it is contaminated with the blood, it can quickly spread in the body, it only takes twenty or thirty seconds to kill a person, and it will continue to spread to the whole body after death, until all the functions of the body are completely suspended.
