At this time, outside a small community in the north of the city, the night sky was lit up by blue and red alternating police lights, and it was destined to be unquiet tonight.

The first victim moved to the neighborhood the day after the nail case, and because she lived with her boyfriend, the person who found her body was her boyfriend.

When Xu Sa and Su Tong came up, they saw the deceased's boyfriend slumped on the ground, crying in a daze.

"It's all my fault, if I had agreed to stay with her tonight, nothing would have happened......" The man cried with tears and snot on his face, "I, it's all my fault, what friends I went out to meet!" ”

Su Tong frowned and asked in a low voice about the situation of the police officers on the side.

"Alas, this is the victim's boyfriend, he said that the victim's mood has not been stable recently, and he has always felt that someone is going to kill her." The officer sighed and recounted what he had asked, "After checking the surroundings of the house and finding that there was no danger as the deceased said, he did not take this incident seriously, but only the psychological effect of the victim." A friend of his had a birthday tonight, and he was supposed to take the victim with him. ”

"But the victim was not feeling well when he left the house, so he stayed at home to rest." Speaking of this, the police officer glanced sympathetically at the man who was still sitting on the ground, "After eating with friends outside, he was still a little worried about the victim, so he rushed back in advance, but what you can see is such a scene......"

Su Tong frowned, turned around and was about to enter the victim's house, but was stopped by the police officer who was talking to her just now, "You'd better take this in." ”

The police officer handed her a mask and glanced at the direction of the door with a complicated expression, "The scene inside may be a little uncomfortable......"

Su Tong took the mask clearly, but he didn't bring it. After experiencing the previous heart-digging case and the case where the perverted doctor used the patient as a carrier for planting mushrooms, Su Tongjue should not be able to stand any scenes.

Walking into the door of the rental room, the living room was very clean, and there were many picture frames on the table and cabinets, and it could be seen that the relationship between the deceased and his boyfriend was very good.

There was a very strong smell of blood in the air, Su Tong wrinkled her nose, she roughly understood what the police officer at the door said just now.

She searched for the smell of blood all the way to the bathroom, Xu Sa came in before her, and was already checking the scene.

The situation in the bathroom is very similar to the scene of the nail case, there is hot water in the bathtub, and the hot water has been stained red with blood.

The only difference from before is that the environment in the bathroom is very messy, and everything is swept to the floor, which is messy.

There are also many traces of blood splattering on the wall of the bathroom, and judging from these traces of the scene alone, there must have been an argument between the victim and the murderer.

"How did the deceased die?" Su Tong was a little dizzy from the smell of blood, and finally chose to put on a mask and walked to Xu Sa's side.

"I don't know." Xu Sa squatted on the edge of the bathtub, and the two sword eyebrows were entangled together, "The corpse has been brought back by Chen Lao's students, I just looked at the photos they took, and the deceased has several wounds on his body, which are fatal if the depth is enough." However, it is also possible to suffocate to death......"

If it is suffocation, it can show the perversion of the murderer, first torture the deceased with knife wounds, create such marks on the wall, and finally drown the person in the fish tank.

"How? Now what do you have and what inferences do you have about the murderer? Xu Sa sighed and got up, before the case was killed, even if they were pressured by the media and the public, they still had some time.

But now it's different, once someone dies, everything will be changed.

"Why did the killer suddenly start killing people now?" Xu Sa hugged his arms and looked at the bathtub in deep thought, "At the beginning, he can make people fall into a coma unconsciously, and he can also pull out the victim's nails unconsciously, he has the ability to commit crimes." But he left the victim behind and waited until now to do it, what is it for? ”

Su Tong didn't answer Xu Sa's question, but looked at the surrounding environment seriously.

The bathroom is very cramped, preventing a bathtub and toilet from almost only accommodating two people, and it will be difficult to accommodate one more person.

If in such an environment, the victim resists, the murderer cannot leave no clues.

"Boss!" Zhou Li's voice came from the door, "We and Officer Wen are here!" ”

Su Tong's body trembled slightly, all the thoughts that had just risen in her mind suddenly froze, and she glanced back with some embarrassment, just in time to meet Wen Yan's indifferent gaze.

"What about the corpses?" As if he didn't see Su Tong, Wen Yan walked directly around her and walked into the bathroom, glanced at her and asked Xu Sa, "How did you die?" ”

Xu Sa handed him his mobile phone, which was a photo sent to him by Chen Lao's student just now, "When I found it, the deceased was in the bathtub, with several knives in his body, and the cause of death can only be concluded after the dissection is solved." What about you, what do you think? ”

Wen Yan only glanced at the photos on his phone, then retracted his gaze indifferently and slowly looked at the surrounding walls, "I see anger." ”

Everyone glanced at each other inexplicably, and then heard Wen Yan continue to say, "The murderer is very angry, what ...... is he venting?"

"What about you?" Xu Sa frowned and looked at Su Tong, "You think so too?" ”

Su Tong was slightly stunned, quickly came back to his senses, looked around with Wen Yan's statement, and nodded, "Indeed, these traces look more like someone suspiciously made them." ”

"Huh?" He Xingchen, who had been listening carefully at the door, was speechless, "Officer Su, you mean, these blood marks on the wall were all made by the murderer!" "Why!

"It should be." Su Tong nodded, she also felt strange just now, if these traces were left after the dispute between the victim and the murderer, then these traces were too regular and clean.

After Wen Yan's reminder, she thought of another possibility, that is, the murderer was suspiciously drawn, and the purpose was to vent the emotions in her heart.

"This is too perverted......" He Xingchen snorted coldly, not only killing people, but also painting on the wall with the blood of the dead.

"But why is that?" Xu Sa raised his eyebrows, "If the murderer is the same person, the changes and gaps in the two crime scenes are too big." ”

When the nails were pulled, it could be seen from the scene of the crime that the murderer was a calm and extremely cautious person, but looking at the current scene, the murderer was simply like a madman.
