Chapter 253

"I really didn't expect that this speed-up came about in this way."

"No, Old Liu, I just realized—the biggest freak is you."

"Damn, that yellow stuff, I can't take it, I'm starting to feel nauseous now."

"So this is what my fat looks like, yue, too disgusting, Old Liu, no need, no need, I'd rather not have this speed-up."

Chen Fan said, "Well, how should I put it, people who often eat vegetables tend to have clearer fat, people who often eat meat have murkier fat, and people who eat seafood have fat that smells a bit off."

Wait a moment, wait a moment.

Chen Fan shut his mouth.

Old Liu looked at Chen Fan and said, "How did you tell this thing apart?"

"Nothing, nothing, I just, I just happened to read a lot of material."

Was it really because of the material?

This guy definitely has something off about him.

At this moment, Old Liu pulled down the blackboard and wrote two characters: infant.

The instant those two characters appeared, the hearts of the livestream audience nearly stopped.

"This is a very old case, so old that every time it comes up, we feel disgusted."

Old Liu looked at everyone.

Qin Ming, in the observation room, said helplessly, "What I'm about to say may cause everyone's blood pressure to rise, and that is, how to identify a person."

A person?

Everyone didn't quite get it.

Teacher He said, "Is it favoring boys over girls?"

Qin Ming said, "Yes, favoring boys over girls, but now there's also another thing, called favoring girls over boys, and there have already been some examples—some people who don't like their sons really will abandon them, even really strangle them to death and the like."

Song Zuer said, "Is it for money?"

"Pretty much. In some remote areas, the parents don't really work, they just rely on having daughters, and once the daughters grow up, they marry them off and take the bride-price money. After all, no matter how hard you work your whole life, you can't earn a million, but if you ask for bride-price, you can get a lot of money."

Old Liu began to bring out the PPT.

"In a mature infant the skin is taut and full; a marked erythema appears 5–6 hours after birth, called neonatal erythema; the erythema subsides after 1–2 days, accompanied by peeling; mild neonatal jaundice appears at 2–3 days; the jaundice deepens on the 4th–5th day, and the skin turns brownish-yellow; the jaundice resolves naturally by the 7th–10th day, and may sometimes be prolonged to resolve by the 14th–30th day."

From this point, you can quickly determine how old this infant actually is.

Qu Yiling felt genuinely uncomfortable—damn, forensic doctors really do run into everything.

Xiang Qinqin said, "What about other methods?"

Old Liu said, "Look at the umbilical cord."

"At 6–12 hours a mild inflammatory reaction occurs in the tissue at the base of the umbilical cord; at 24–36 hours a distinct demarcation ring, called the inflammatory ring, appears—this is the main feature used in forensic medicine to identify a newborn; by 2–3 days this area becomes markedly red and swollen, and the umbilical cord gradually dries and shrivels; by the 5th–8th day the umbilical cord is completely dried and shriveled, turning black; by the 12th–15th day the umbilical fossa forms; after 3 weeks it is fully scarred over."

The few of them quickly wrote it all down—these things, they really hoped, would never need to be used.

At this point, Old Liu continued, "There's also one more thing, and that's the caput succedaneum."

"3. Caput succedaneum: during delivery, the soft tissue of the fetal presenting part is subjected to strong compression, causing lymph and blood to stagnate in the unpressed presenting part, forming a localized subcutaneous tissue edema that produces a tumor-like protrusion, called caput succedaneum. Stillborn infants without blood circulation do not develop caput succedaneum. On autopsy, cutting into the caput succedaneum reveals loose subcutaneous tissue filled with fluid, jelly-like in appearance, with indistinct borders and a fluctuating feel."

Three points, only three points, but no matter which point, it makes one think of living, breathing infants.

At this moment, Laosongtui Sect walked in, saw the lesson on the blackboard, and said, "In the middle of class? Let me give you a case—someone gave it to me and asked me to find you to help out."

Old Liu looked at the report and said, "Is this an indicator?"

Laosongtui Sect nodded and said, "Yes, this indicator data is the result of a journalist's investigation, then given to me anonymously, saying that at a certain hospital, the proportion of child deaths is a bit strange."

Everyone suddenly thought of something not so pleasant.

Old Liu looked at the proportion and said, "With modern technology, this situation rarely occurs, right?"

"Yes, it rarely occurs, so according to big data, infant deaths are generally stable at a certain proportion, fluctuating with the birth rate, but the numbers won't differ much. This case here is a bit odd, because too many children are dying."

"Anyone caught?"

Laosongtui Sect said, "No evidence yet, we're looking for evidence."

"Can you find the child?"

"Just one. I've already called and asked over there—go take a look."

Old Liu turned off the blackboard, took Chen Fan, and left directly with Laosongtui Sect. This sort of thing still wasn't suitable for Xiang Qinqin and these kids to see.

The audience watching the livestream were silently praying, hoping it was just a coincidence.

Arriving at the family's place, the child had already stopped breathing, lying quietly to one side.

Chen Fan and Old Liu silently lowered their heads, then looked at the family and said, "We need to investigate, and we need your consent, and a family member to accompany us."

The woman was crying; the man held back his tears, told the woman to step aside, and said, "I'm going to light a cigarette, is that alright?"

"It's fine, no problem."

The man stood to one side, gesturing for the two to continue.

Old Liu was in charge of examining the child's skin, while Chen Fan was in charge of examining the umbilical cord and so on.

The skin examination showed no problems at all.

Chen Fan looked at the child's chest area and said, "Something here seems off, doesn't it."

Old Liu looked at the chest area, then took a hammer and gently tapped it once.

The sound traveled to Old Liu.

"This…"

Chen Fan said, "It seems like the breathing isn't quite right—it should be death by asphyxiation. If we could do an autopsy, we could see the problem."

The parent said, "Do the autopsy, I'll go with you."

Inside the forensic institute, Chen Fan took up the knife and began to work, cutting open bit by bit.

This was the smallest child Chen Fan had ever autopsied, but it was precisely because the child was so small that Chen Fan was being so careful.

There was no rush; instead, he began carrying out his own procedure very carefully.

When the blood sample was in hand, Chen Fan said, "Teacher, I think I know what happened."

Old Liu looked at it and said, "Mm, no problems at all, perfectly healthy, but suffocated. Birth asphyxia usually comes with compression injuries, but there isn't a single extra mark on the baby's body. It can only be... damn it."

Old Liu cursed outright.

This was the first time Old Liu had ever cursed.

Old Song said, "I got it. I'll go catch the person on my end."

Chen Fan said, "I'll go with you."

Old Song nodded, and Zhang Tianxiong followed.

The two of them set out.

Meanwhile, Old Liu sighed and slowly helped stitch the child's body back together. Rarely seen, Old Liu began to shed tears.

In the observation room, everyone was crying.

Song Zuer wiped her tears and said, "Teacher Qin Ming, how exactly did he die?"

Qin Ming sighed, wiped the corner of his eye, and said, "Very simple. Just use a hand and gently cover the baby's mouth and nose, and that's it."

????????

Holy shit, what a beast.

At that moment the baby couldn't cry for help, so no one would notice.

But what kind of beast would lay a hand on a child?

On the hospital side, the doctors and nurses in charge would all be questioned and investigated.

There were a lot of people.

And Old Song very quickly locked onto a person.

When Old Song could find the person so quickly, it meant that the same kind of thing had happened before.

A woman was found by Old Song; without a word, she was taken away in cuffs.

Chen Fan looked at the woman and was basically certain it was her.

The laughable thing was, this woman's deepest secret was only that she had cheated on someone before — not that she had killed a baby.

Qin Ming said quietly in the observation room, "This woman probably can't have children, so she's taking it out on them."

Teacher He said, "If Old Song could lock onto her, does that mean—?"

Qin Ming said, "Yes, it's happened before, and more than once."
