At about 11 o'clock in the evening, Gu Song was lying on the bed in the guest house, although he was attacked by sleepiness, he was so hungry that he couldn't sleep. With a thunderous grunt, he sat up from the bed depressedly, and quickly glanced around the room, but there was nothing to eat except for two bottles of mineral water and half a pack of Yuxi cigarettes.

He grabbed his mobile phone from the bedside, dialed Xia Shi's number, and asked eagerly before the other party could speak, "When will you come back?" Bring me something to eat. ”

"Eat, eat, eat, you know how to eat!" Xia Shi replied to him angrily, sounding in a very bad mood.

Gu Song was a little confused, and was about to ask him if he had taken gun medicine, when he heard Xia Shi say in an unusually serious tone: "Team Qiao just asked me to inform you that there was a murder in a residential building in Yangjiao Hutong in the northwest of the county, you hurry up and call Ruonan and Forensic Doctor Chen to come to the scene of the crime together." ”

"What case?" Gu Song was excited, and he instantly fell asleep.

"I don't know the specifics. But I'm sure you won't want to eat anything after watching the crime scene. ”

Twenty minutes later, Gu Song and his entourage came to the vicinity of the old-fashioned residential building where the crime occurred. Because the road in front of the building was too narrow, it was inconvenient for the car to enter, so they could only park their cars on the main road outside and carry the survey equipment through the alley.

"The road is so narrow, what if there is a fire?" Qi Ruonan said worriedly as he walked.

"In the past, people didn't think so much about building houses. Although the economy of this small county is underdeveloped, new buildings are being built everywhere, and it is estimated that these old houses will have to be demolished in a short time. ”

"Let's dismantle it sooner, it's scary to think about those safety hazards."

"Fortunately, there are monitoring facilities in this alley." Gu Song said and pointed to the position diagonally above, "Although I don't know if it can be useful, it's better than nothing." ”

As they spoke, the three of them had already arrived at the residential building where the accident occurred. Qiao Sheng and Xia Shi had just arrived from other places, and they didn't know much about the situation upstairs.

According to Officer Wu, who was the first to arrive at the scene of the crime, at around 11:10 p.m. that night, Mr. Kong, who lived on the sixth floor, came home from work at the hot pot restaurant and found that the door of the opposite room was wide open. He is an old resident here, and he is very familiar with the neighbors around him, and he knows that there is a young and lovely girl living opposite, whose name is Tang Jing.

He was worried about whether something was going on in the girl's house, so he first stood at the door and observed the situation inside. He didn't see anything at first because there was no light on in the room, but his nose smelled a disgusting smell of blood. He realized that something might be wrong inside, and boldly walked into the living room. When he touched the switch on the wall and turned on the chandelier in the living room, he saw the most terrifying scene in his life.

The girl lay on the tiled floor of the living room, covered in blood, barely recognizable. The most terrible thing is that the girl's intestines were pulled out of her body and wrapped around her neck, like a small snake with blurred flesh and blood.

As a man in his thirties, he experienced for the first time in his life what it was like to be frightened. He crawled out of the room and vomited for a long time before calling the police. Until the police arrived at the scene of the crime, his legs and stomach were still weak, and he had to be held by someone when he walked.

Regarding the information about the victim, Gu Song and they already have a preliminary understanding, not only that, Xia Shi also personally went to Luo Tong's clinic a few days ago and asked Tang Jing to verify Luo Tong's alibi.

No one thought that this simple and lovely girl would become the second target of the demon. The murderer kills so fast, will there be a third, a fourth? The case became more and more serious, and everyone's hearts were extremely heavy.

However, even more depressing news is yet to come. As soon as the investigators entered the scene, their hearts were half cold. They originally thought that this time the case happened indoors, and the murderer would leave some traces of the crime, but as soon as they saw the water stains left on the ground, they knew that the murderer had carefully cleaned up the crime scene, and it was difficult to find valuable clues.

After comparison, the two shoe prints left at the scene of the crime belonged to Mr. Kong, the informant, and Officer Wu from the police station, respectively, and the rest of the shoe prints were all wiped off by the murderer with the mop at the victim's home. The shoe prints in the corridor are very complicated, and it takes a certain amount of time to extract and compare them.

Qi Ruonan collected a total of three fingerprints at the scene of the crime, which belonged to the victim Tang Jing, Mr. Kong and Officer Wu.

There was no sign of the door lock of the victim's house being broken. The murderer should have attacked the victim from behind with a blunt object while the victim was returning home and opened the door, and then moved him to the living room to carry out the next criminal act.

Medical examiner Chen conducted a preliminary examination of the victim's body and determined that the time of death was between 8 and 9 p.m.

The victim had a blunt force blow (non-fatal wound) to the back of his head, and the real cause of death was that the victim's intestines were pulled out of the body by the killer.

The modus operandi of this crime is exactly the same as that of the "7.7 Murder Case", and it can be determined that the two cases were committed by the same murderer. As for whether there was another murderer in the case five years ago, and whether there was a connection between the two murderers, this is just Gu Song's personal speculation, and it cannot be confirmed for the time being.

Just like Xia Shi said on the phone, after seeing the crime scene upstairs, Gu Song really lost his appetite at all. He was glad that he didn't vomit this time, otherwise he would have to embarrass himself in front of his colleagues and be gossiped in secret.

"The victim had a brand new bottle of anti-wolf spray in her pocket, and it seemed that she still had a certain sense of self-preservation. It's a pity ......" Forensic Doctor Chen sighed and shook his head, and put the small bottle into the evidence bag.

Hearing the words "anti-wolf spray", Gu Song and Xia Shi looked at each other for a moment, and their faces were a little ugly.

Many people may not understand how lethal this little spray can be, but the two of them have experienced firsthand how powerful this thing can be. Although the main ingredient of anti-wolf spray is capsaicin, which has no organic toxic side damage to the human body, it will also cause certain harm to others if used improperly.

In 2014, two teenagers at the back of a train on Guangzhou Metro Line 5 were randomly playing with anti-wolf spray, and 13 people suffered minor abrasions when passengers on the train collided during evacuation.

"Maybe it's because there was a case in the county, and the victim specially prepared this thing to protect himself......" Gu Song said as he picked up the mop placed at the entrance. Ruonan, come over for a moment. He waved to the other end of the living room.

The latter went to the door, crouched down and looked at the dirty mop; "There was a clump of hair wrapped around it, which should have been unintentionally dropped on the ground by the victim in her usual life, and the house where the woman lived had such characteristics. If the killer accidentally drops his or her hair at the scene and wipes the floor with this mop after committing the crime, his/her hair may also be mixed with it. ”

"That's right, that's what I meant." Gu Song Chong Ruonan gave a thumbs up.

Xia Shi looked at Tang Jing's corpse thoughtfully and said, "I went to Dr. Luo's clinic a few days ago to find out about this girl, and now she has become the target of the murderer, do you think this will be a coincidence?" ”

Gu Song replied, "I don't know if it's a coincidence, but I think we should investigate Dr. Luo Tong more carefully." ”
