Duan Lin's father also ran in to look, and when he saw the blue blood on the ground, he was shocked and said, "What is the color of this blood?"
Lin Dongxue explained to him that this is a luminol reagent, and when it reacts with blood stains, it will turn into a fluorescent blue state, and the uncle nodded knowingly.
Chen Shi walked over and said "borrowed" to the uncle. The bathroom was very narrow, and there were large swabbing blood stains on the uneven tiles. The bathroom was very clean when he came in before. It seems that this blood stain has been cleaned up.
"Brother Chen, the tiles are not very professionally laid, and some blood stains can be extracted in the crevices," the technical police officer said to him.
"This seems to be the result of the dismemberment." Chen Shi knelt down and looked back to see that the uncle had already gone out. He whispered to Lin Dongxue, "Is there something wrong with Duan Lin's father?"
"Is there a problem? I didn't feel it."
"Did he ask you just now, what is the color of this blood, this large piece of blue faint, looks like the toilet cleaner, how does he know that it is blood?"
Lin Dongxue raised her eyebrows suddenly and noticed this suspicious point.
The technical police expanded the scope of the investigation. When they sprayed luminol on the wall, they accidentally discovered that there were some splattered blood stains on the wall, but the location was very low, under the shower head.
"Xiao Zhou, unscrew this and check it." Chen Shi pointed to the drain.
Chen Shi and Lin Dongxue came out temporarily, and Chen Shi asked the uncle: "Have you used the bathroom in the past two days?"
"It will definitely be used."
"Have you showered in it?"
"I... I'm not very used to this thing. I usually boil a pot of water on the stove and wipe my body with a towel."
"Have never used a water heater?"
"Yes, never used it."
"When you came, was the water heater on or off?"
"On or off?" The uncle frowned and thought.
"Are there any bright words on it."
"It doesn't seem to be there." The uncle took out a pack of cigarettes and handed one to Chen Shi. Chen Shi declined, but the uncle said, "I'll go outside and smoke a cigarette."
"Okay."
Lin Dongxue opened a wardrobe and sighed with emotion. This girl has a very fashionable taste in buying clothes. She recognized a few new spring clothes that were only released this year.
"What is the monthly income of a female spinning mill worker?"
"I also saw a pile of cosmetics on the table. I don't know the price too much."
"Let me see."
Lin Dongxue went to the table, picked up the cosmetics and looked at it, saying, "It's not valuable, but it's not cheap... The last time I chatted with a little sister born after 00, she said that she spends more than 1,000 yuan on makeup a month. He also said that nowadays girls can't go out without makeup, and feel that they are old."
"She has only been in Long'an for three years, and she won't be able to survive more than five thousand yuan to work in a spinning mill, and she feels that the cost is not low."
Chen Shi saw an article on the Internet saying that girls and boys in the city have the same salary, and their living standards are not at the same level. Boys have to save some money to buy a house and save gifts to make plans for the future; girls have full income. Used to dress yourself up, those flowers on the street, like a little girl walking out of a garden house full of roses, you will find that they are all ordinary working class, wearing clothes of thousands of dollars, and eating a few dollars when they go home. Of instant noodles, and tell me how good I am in my circle of friends.
Of course these words were somewhat disrespectful to the deceased, so he resisted saying it.
The technical police found some hair and blood stains, as well as some human tissues in the drain. The amount could not be left when the wrist was cut. No one would cut their wrists so that dander was flying. It could only be left when the corpse was broken. of.
Chen Shi speculated that Duan Lin committed suicide by slashing her wrist while sitting under the open shower head, because her body would feel cold when she was slashing her wrist. Continuous pouring of hot water on her body would make her a little more comfortable, and it would also speed up blood circulation and cause death. Faster.
If this is the case, Duan Lin should not have the ability to turn off the shower head by herself. Checking the water consumption of this apartment can predict the time of her death.
Then the corpse divider came here, divided the body into nine pieces in the bathroom, and then cleaned the scene. The technical police mentioned that there was a heavy smell of disinfectant in the cracks of the tiles.
He deliberately checked the door lock, the lock cylinder was intact and there was no trace of being picked.
Then the corpse divider has the key here!
When leaving with the uncle, the uncle took out the smart phone and asked Chen Shi for the phone number. Chen Shi couldn't help but ask, "Is this phone your daughter's?"
"She replaced it and used it for me. I don't know how to use it. I just use it to make calls."
"Then when you came, was there her cell phone in the house?"
"No." The uncle was sure.
"What about documents, wallets, and carry-on items?"
"Neither, or I wouldn't think she was out."
"I noticed a hanger behind the door. Did you hang clothes before?"
"no."
"Well, thank you, we will let you know if we have any clues."
Saying goodbye to the uncle, the technical police went directly back to the bureau. Chen Shi and Lin Dongxue went to the property to check the water and electricity consumption of the family.
On March 23rd, Duan Lin's house water reached one side.
As for the electricity consumption, it has not been interrupted since March 23, which means that there are always electrical appliances in the house turned on. Duan Lin did not buy a refrigerator, so someone must have turned on the lights or the TV.
But on March 24, the water consumption was normal.
Leaving the property, Lin Dongxue said, “Didn’t her father say that he arrived on March 25? Why has the electricity been not cut off?”
"It could only be the corpse division. Someone came in on March 24, turned off the shower head that was always on, and turned on the light. From the electricity consumption, he stayed for quite a while."
"It takes a lot of time to divide a corpse."
"It seems that this person who came on March 24 is the corpse divider."
"Look for witnesses!"
"I'm thinking, is it necessary to find a bodybreaker? He has successfully opened a case to the police for investigation. If we find out who killed Duan Lin, I think this person who has worked so hard will also surface by himself."
"Oh, don't be lazy, check it out!"
Chen Shi was dragged by Lin Dongxue to look for surveillance and witnesses. The neighbors had no impression of what happened so long ago a week ago. In fact, the neighbors didn't even know who lived in this house.
Surveillance, a lot of copies were copied from the security guards, and they were taken back to study slowly, and this rather technical work was thrown to Xu Xiaodong.
It's getting late, and today's work is over. Lin Dongxue didn't eat much for lunch. She was so hungry that her chest was stuck to her back. Chen Shi heard that a newly opened restaurant was engaged in activities. As long as he finished eating a large portion of beef donuts, he would be exempt from the order.
"Oh~" Lin Dongxue raised her fan fist excitedly, "I can eat a cow in my current state, no problem!"
The two went ambitiously, and then paid more than one hundred yuan, helped the wall to come out, and ran to the pharmacy to buy digestive tablets...
