When we came to the project headquarters, Liu Da saw us enter the conference room, so he couldn't wait to hold the fruit and said, "The best lychees, special supplies from the south, I will discuss with you if you eat well." ”

Consult? Liu Da wants to discuss with us? Is there an objection to the nature of the case we are proposing? I can't help but be a little nervous, because the data they investigate is more comprehensive in all aspects, so the analysis of the entire case will be more targeted, and I, the forensic doctor, can only be based on the corpse, based on the scene. However, if a forensic doctor is affected with the investigation data, it is estimated that the trap is not far away.

"Liu Da, we don't dare to eat your fruit, who knows how big the pit is in the back." I pinched one of the largest red lychees, "You better say it directly, don't you think it's not like an acquaintance committing a crime?" ”

"Acquaintances committing crimes? I'm not against it. According to our investigation, there is no such suspect yet, Ah Hu does not have many friends, the circle is very small, most of them are very good friends, and there are no economic disputes, I don't doubt your on-site analysis, do you want to consider other possibilities? "Liu Da is still not very comfortable with our opinions, and I also understand this, any analysis is plausible before each case is solved.

"Then is his wife Shuhui ruled out?" I took the stack of transcripts handed over by Liu Da.

"His wife is not like a murderer, and the time of the crime has been ruled out." Liu Da said with a frown.

"Then why did she say that her husband killed her daughter and then committed suicide?" I asked, confused.

"This question, it's normal, Shuhui said so, Ah Hu has always suspected that this daughter is not his own, so he didn't like Nana since he was a child, and often beat and scolded, now Nana is in junior high school, and she has always lived in school, it wasn't a weekend, it stands to reason that she shouldn't be on the scene, we went to ask the school to find out that she said that her stomach had been hurting at noon that day, so she asked for leave to go home." Liu Da took a sip of water and continued, "Shuhui's suspicions are not unreasonable, we visited the neighborhood, the neighbor also has screenings, and the husband often abuses his daughter. ”

I heard that Ah Hu suspected that Nana was not her biological child, so she became interested and asked for a paternity test on Shuhui's blood sample, and Liu Da immediately agreed. If after the biological relationship came out, Nana was indeed not born to Ah Hu, then Ah Hu's suspicion has a certain factual basis, there are people outside Shuhui, so there are still quite a lot of cases of friction caused by emotional disputes and murders.

"Liu Da, I still have some things to ask Shuhui." I want to go and get in touch with Sook-hye directly, to look at this woman head-on, to find a feeling.

"That's right, when you go to collect blood, just ask." Liu Da readily agreed.

Shuhui is a very ordinary woman, with not very obvious freckles on her slightly chubby face, although she is a little older, but under her careful dressing, she still looks like she has some charm.

When she saw me, she probably felt that she was the same woman, and instead of feeling kind, she felt a little wary, and I noticed the momentary hostility in her eyes.

Although the woman in front of me has not been upgraded to a criminal suspect, I am now slowly entering the role, and I have begun to have a scrutinizing attitude towards anyone involved in the case, although I can't say that I doubt everything, but there is always some element of suspicion.

I looked very serious and said straight to the point: "We are going to do a paternity test on your child, and we are going to take your blood." ”

Seeing that I was so serious, Shuhui's eyes were a little messy, and she said timidly, "What other paternity test do we need for our own children?" This seems redundant. ”

After Shuhui finished speaking, she went with her right hand and stroked her brown hair.

"That's not the case, this is the need to handle the case, and some things are clarified and helpful in solving the case." I saw that Shuhui was a little reluctant, so I explained further.

"I don't want to, everyone is dead, I don't want any more accidents." Sook-hye clearly resisted my persuasion.

"I hope you cooperate, as long as a drop of blood is enough, don't you want to solve the case?" I tried to convince further.

Shuhui finally reluctantly let Ling Fei take blood from her fingers, and when the blood needle pierced her fingertips, I saw her whole body trembling in the afterglow, I don't know if it was the sudden pain of the needle prick that made her tremble instinctively, or if she was afraid of something.

While Shuhye was distracted, I secretly observed whether there was any damage on the exposed parts of her body, and she was already visible under my eyelids, and I didn't notice even a single scratch.

If Shuhui was the direct murderer, if Ah Hu had some scuffles with her before being hit, then Shuhui would inevitably have some injuries such as scratches, but now there is no damage on the exposed parts of Shuhui's body.

But if the murderer suddenly attacked at the time of the crime, there was no need for the previous scuffle at all, and the murderer would not have left any injuries, so based on this alone, Shuhui still can't rule it out.

"I want to ask you why you suspect that your husband killed his daughter." I looked at Shuhui's eyes very confused, and I always felt that she didn't say anything.

Shuhui glanced up at me, quickly shifted her gaze, and she said softly, "He has always been bad to my daughter. ”

Hearing her say her daughter, I paused for a moment, thinking that Nana was really not Ah Hu's biological son, so I asked, "Why do you emphasize that this is your daughter, isn't Nana her daughter?" Is there something you yourself that you haven't explained? ”

Shuhui hurriedly explained: "That's not what I mean, Miss Officer, our family is poor, no one will come to harm us, no one will do such a thing except him." ”

According to Shuhui's confession in the transcript and my current observations, Shuhui's suspicion of direct murder is extremely low, but Shuhui's words and deeds are always a little abnormal, which makes me feel that there is something wrong, this woman must not let go now, if this child is really like Ah Hu suspects, then Shuhui's extramarital lover may be an important suspect, I went to the autopsy room with this doubt.

Nana's corpse is already high**,**vein network is dense all over the body, several skin has been broken,**blood continues to leak out,**fly maggots crawl around, the longest is about four millimeters, Ling Fei is struggling to catch one of the fly maggots that is shaking his head, to put it on the stainless steel ruler, the fly maggot is very dishonest, on the stainless steel ruler body stretches and shrinks, and keeps crawling.

"Call you bad!" Ling Fei held a stainless steel hemostat in her right hand and kept chasing the fly maggot, pressing its body, "Cooperate with it, it'll be fine for a while, auntie, I only need your length, and I won't kill you!" ”

After a lot of effort, Ling Fei finally figured out the length of the maggot, and she said to the tape recorder: "The maggot is 3.9 centimeters long, and according to the law of maggot growth in summer, it is inferred that the death time of the deceased is one and a half days. ”

Ling Fei's persistence in measuring the length of the maggots reminded me of when I first went to work, once I almost fell into the river to measure the temperature of the canal water, but when I fell, I grabbed a life-saving straw, which was a withered thorn strip hanging in the water, and when I climbed ashore wet, I found that the thermometer had been shattered.

"Teacher Su, do you think my inference is correct?" Ling Fei let go of the fly maggot, and the fly maggot crawled away leisurely on the dissection table by itself.

"Half a pair, your time is the time for the development of fly maggots, and you also need to add the hatching time of fly eggs, so that it is just two days." I said to Ling Fei.

"Also, I'm always throwing things off, and theory is divorced from reality." Ling Fei laughed at herself.

"It's normal, you've only been debuting for a few days." I shook the scalpel in my hand.

"I don't know how many years it will take to see the scene independently?" Ling Fei put the steel ruler into the washing basin, and the mouth behind the mask must have been cocked high.

"Five years, our forensic research institute has a mandatory rule that you must be at least five years before you can work independently." I glanced at her, and she seemed a little aggrieved.

"It's going to take five years, then I'll be old." Ling Fei shouted, and she realized that she seemed to have slipped her mouth again, "No, no, I'm still tender for five years, like Teacher Su." ”

"Five years older than you, you think I'm old? It seems that you can only be your teacher, and there is a generation gap to be a little sister. I said pretending to be angry.

"Teacher Su, you really treat me as a sister, I am willing, I will call you Sister Su in the future." Ling Fei smiled and said quickly.

"Alright, you better take a good look at Miss Nana's stomach and see if there's anything found inside." I lowered my head as I spoke.

The damage to the forehead has been dealt with, I began to shave Nana's hair, except for the hammer blow wound on the forehead, no other damage was found on the entire head, it seems that she fell on the low table with food after being hit head-on, and overturned the low table, the food on the low table was dumped on her body, the murderer did not do any unnecessary processing on her, it seems that the murderer's target was indeed not on her.

"Teacher Su, my stomach is empty." Ling Fei cut open her stomach and showed it to me with both hands.

The little girl's stomach was empty, and she should have not eaten for several hours, which further supports my point of view, the little girl is not the diner of the two pairs of dishes and chopsticks, which can not only show that the case is actually divided into two stages, the first stage when Ah Hu was killed, the little girl was not present, but also show that the other diner was the biggest suspect at the time of the crime.

Since the suspect and Ah Hu can eat together, the relationship must be very close. Liu Da's worries seem to be unnecessary, and the investigation of the suspect still has to be locked in the circle of acquaintances.

I bet on a paternity test, and the results of the paternity test will directly affect my judgment of the nature of the next case. If the paternity test shows that Nana and Ah Hu have a biological relationship, then Ah Hu's suspicion is just his unilateral suspicion, in fact, Shuhui has no so-called lover at all, this clue may be broken, but if the results of the paternity test show that Nana was not born to Ah Hu, then the value of this clue is great.
