crime scene

Xie Qian drove the jeep in the traffic.

Looking out from the car window, the street trees on both sides are moving backward rapidly.

As soon as a person gets old, all the big and small problems of the body come out. In addition, after staying up all night, he starts to feel dizzy and the speed of the car slows down significantly.

Chu Duanyu drove Su Nian to the front seat before getting into the car, and lay down on the back seat for a while.

Taking advantage of the red traffic lights at the intersection, Xie Qian seized the time to drink some water and light a cigarette to wake himself up.

"Damn it, the oil is almost bottoming out. This car is fun to drive, but the fuel consumption is a bit high." Xie Qian complained as he parked the car at the gas station, "Isn't this a waste of time, master, add 93 , 200 yuan, invoice."

"okay."

Then I walked into the convenience store next to me and bought some snacks, Skittles, sandwich rolls, bread, drinks, and ham sausage.

Said not to eat, didn't say not to eat snacks, right? Xie Qian threw the bread and water on Chu Duanyu, who was lying and sleeping in the back seat, while he ate a big jar of Skittles himself.

"Captain, you are so kind..." Chu Duanyu groaned, tore open the bread and lay down to eat.

"Work more and talk less."

Chu Duanyu giggled twice.

Su Nian sat in the co-pilot, looked down on the mobile phone to check some information, to see if he could find the connection between the three cases, shook his head and declined the bread handed over by Xie Qian.

"He doesn't want me, I can't eat enough." Chu Duanyu reached out to bring the bread.

At that point, Qian Qian gave him a glance and continued driving.

1803, Block B, Longxiangyuan is the specific address of the first case. Chu Duanyu licked the bread crumbs on his fingertips, and distributed the gloves and shoe covers to Su Nian and Xiqian.

"Boy, pay attention in a while, don't destroy the scene." Chu Duanyu reminded.

Xie Qian stretched out his hand and handed over a mint candy, which he bought at a convenience store at a gas station. Although the corpse and the smell were gone, the big blood was still disgusting.

Su Nian took it, opened it and put it in her mouth, Chu Duanyu nodded to Xie Qian, and opened the door.

The large bloodstain in the room has completely turned black compared to the last time. I don't know if it's a psychological effect or something, but Qianqian still smelled a bad smell. Looking at Su Nian again, he frowned, covered his mouth and nose, and moved up and down his throat. Rolling, suppressing the feeling of vomiting.

Chu Duanyu naturally died. He didn't feel sick when he saw the corpse for the first time, let alone a big puddle of dried blood.

People, after death, it's a puddle of flesh, and then it turns into mud and dust, there's nothing disgusting about it.

Su Nian approached the bloodstain and knelt down to examine it.

"Don't just look at it, let's look for it together." Xie Qian patted Chu Duanyu's shoulder and walked to the kitchen to check.

Chu Duanyu went into the bathroom.

There was nothing unusual about the bloodstain itself, but Su Nian found small dragging marks where the blood dripped.

The longer the oxidation time of the bloodstain, the darker the color. Perhaps the trace inspector did not notice it when the number was collected for evidence, because the trace was next to the blood drop, very shallow, only a short section, in a regular curved shape , are easily overlooked.

Su Nian took out her phone and took a picture.

"What did you find?" Qian Qian came over and asked

Su Nian showed him the photo, got up and went to the bathroom by herself.

Records show that the carrion and bone residues were found in the sink. The murderer has no anatomical basis and is doing delicate work, so he should not be wearing gloves.

Then you must wash your hands after removing the soft tissue, maybe you can find something on the tap.

"Whoa-"

There was the sound of flushing from the bathroom, and then Chu Duanyu came out of the bathroom, and happened to see Su Nian walking to the door of the bathroom.

"Are you going to the toilet too?" Chu Duanyu asked

"Chu Fayi, did you find anything on the faucet?" Su Nian asked at the bathroom door.

"What can I find on the faucet..." Chu Duanyu froze for a moment, and quickly brought the investigation box, "It's been too long, let me try."

"Where did you find the dagger made of human bones?" Su Nian turned around and asked Xie Qian who was behind him.

"On the bedside table in the victim's master bedroom, number 4." Xie Qian replied

The layout of the master bedroom can be regarded as warm and elegant wallpaper. I bought the main furniture, bed, dresser, bedside table and wardrobe as a set.

There is a large square mark on the wall. It seems that their wedding photo used to hang here, but now that their relationship is not good, they have taken it off, leaving only this mark.

Seeing him staring at the imprint in a daze, Xie Qian stretched out his hand to stroke his soft hair.

"Don't think too much."

Su Nian shook her head, looked around in the bedroom, Xi Qian was not idle, opened the closet and checked.

They have already been searched for the first time at the scene, and there may not be any clues if they are searched again.

"Unfortunately, only a fingerprint with an unclear outline was found on the faucet." Chu Duanyu sighed, walked out of the bathroom, and stood at the door of the master bedroom.

"Talking doesn't affect the work, so hurry up and help." Xie Qian gave him a white look while talking, but the movement of his hands stopped, "Why is the medicine box here?"

Su Nian also stopped what she was doing, and went to Qianqian's side.

The medicine box was found in the gap behind the head of the bed. If Xie Qian hadn't given Chu Duanyu a glance, he wouldn't have been able to find the medicine box by the reflection of the ground.

Xie Qian pulled it out, sat on the ground and patted the dust off his hands, and opened the medicine box.

Gauze, scissors, Band-Aids, standing medicines, and... needles.

The specifications of the needle tube looked familiar, so Qian Qian quickly found out the photos of the scene of the second case stored in the mobile phone, and the naked eye and visual inspection were consistent with the model of the needle tube found at the scene of the second case.

"So..." Su Nian said, "Let's go to the scene of the second case."

If this is no coincidence, clues about the third case can be found at the scene of the second case.

Su Nian carefully recalled the details. In the third case, there was nothing around the deceased except the dagger. Could it be the rope that tied him?

It rained a lot that night, maybe the clues were washed into the river, if so, then there is no way to guess how the victim died in the fourth case that didn't happen.

"Why must there still be a case? Sun Dashu didn't leave anything behind, which probably means that he stopped." Chu Duanyu analyzed, "Who can figure out the pervert's thinking clearly."

Su Nian can.

"The murderer has an anti-social personality, which is the most dangerous and socially harmful personality among all abnormal personalities. His retaliatory killing behavior will never end like this."

"Our top priority now is to quickly find the No.4 victim, protect him before the suspect makes a move, and capture the suspect on this basis." Xie Qian kicked the accelerator, and the traffic lights at the intersection did not turn red rushed over before.
