Chapter 40: Time

The body, along with the barbell and quilt, was quickly pulled back to the detachment for further identification.

Su Ping commanded the frogman team to continue the search in this sea area - although there are new cases, the old cases are not yet over, and they cannot be easily put down.

They were really lucky today, and at about four o'clock in the afternoon, they fished out the suitcase that was sunk into the sea by Dai Hong, pulled the evidence back for identification, and the case could be closed.

At seven o'clock in the evening, Su Ping led Qi Yuan to the underground anatomical laboratory of the detachment.

As soon as he entered the door, Lao Yan turned around to look, said hello, and turned his head away, as if he was writing something.

The corpse was laid out on the autopsy table, and it was unknown if the work was completed or only halfway through.

Su Ping asked, "Old Yan, how is it, the work is done?" ”

"No," Lao Yan waved his hand, his hands kept moving, and explained: "There are many clues on the corpse surface, and it is more troublesome to investigate, which is a bit tricky. I'm only halfway through the work, so I'll sort out the clues first, and I'll have to continue later. ”

"Oh? Did you find anything? ”

"Let's talk about the clues found on the corpse surface first." Lao Yan finally stopped moving, put down the pen, and said: "I won't repeat what I said on the spot, just add a few more points."

First of all, I found a small number of eggs in the victim's mouth, nasal cavity, and neck wounds, some of which remained only egg shells, and many of which had not yet hatched.

These eggs were identified as fly eggs, and there were 11 kinds of flies in three families, including the family of Mesophilidae, the family of Lycopodidae and the family of Drumpteridae.

I recorded all these flies and arranged them according to their survival time, egg-laying time, feeding habits, etc., and made an insect succession matrix.

It was found that the overlapping point fly species with seasonal changes in the composition of the cadavagophagous fly community were Avi macrosphazard, Purple-green fly and Brown-tailed Fly, and combined with their reproduction and survival time, it was speculated that the victim died between March 15 and April 10. ”

After a pause, he continued: "In addition, the changes in the corpse, or rather the signs, are quite complex, and the whole is a corrupt giant, but the subcutaneous fat on the abdomen and inner thighs has formed a partial corpse wax.

Depending on the degree, the waxing of the corpse has just begun, and has not yet been completed, combined with the recent corpse temperature, it is speculated that the victim should have died two months ago, but no more than three months ago, according to the clues obtained from the fly eggs, the time of death can be further locked between April 5 and April 10. ”

"So long?" Qi Yuan couldn't help but ask: "The corpse has already formed the Corrupt Giant View, and the Giant View period generally appears within a week after death, and the corpse in the water is relatively easier and appears earlier, no matter how long it takes, the skin of the corpse may be broken by the rotten gas......"

"Logically speaking, this is true," Lao Yan nodded, and said, "but the 'water' here is aimed at fresh water, and sea water is an exception. The salt content of DaChan Bay water is relatively high, which is much greater than the cytoplasmic concentration of general decaying fungi and fungi, which has a certain bactericidal effect and can effectively inhibit the decay process of corpses.

At the same time, due to the saponification and hydrogenation of subcutaneous adipose tissue, local cadaveric waxification is formed, and the cadaveric process is changed. In addition, the corpse wax also has a sour smell, which is also the source of the smell when the quilt is lifted at the scene.

In addition, the number of wild marine fish in DaChan Bay is very small, so although the corpse surface was pecked, the amount pecked was not large, and the corpse was relatively intact. ”

At this point, he paused again before adding, "This is the second point I want to tell you. Combined with the anomalous process of decay and the eggs on the surface of the corpse, I believe that the deceased was not dumped immediately after being killed, with at least a two- to three-day gap.

If the corpse enters the sea after death, the fly is not in a position to lay eggs on the surface of the corpse, which is the first basis; The process of decay of the corpses in the sea is different from that of other environments, which is based on two.

To sum up, I believe that the body was in a bath at the time of death, and it was soaked in the bathtub for at least two to three days after the autopsy, but not more than a week, and it was already a corrupt giant before the body was wrapped in a quilt and thrown into DaChan Bay with a barbell tied to it.

There was no obvious asphyxia reaction in the respiratory tract of the corpse, which can also prove that the corpse entered the water after death and not drowned.

By the way, the last point is to add that the contents of the deceased's stomach have been digested to a considerable extent, and they are in a state of chyme, and part of it has metastasized to the duodenum, indicating that the deceased died about two to three hours after the last meal.

Well, the food is not hearty, mainly rice, Shanghai greens, roast duck and barbecued pork, it is estimated that it is a double roast fast food. ”

Qi Yuan pursed his lips, he also ate roast duck and barbecued pork at night......

"Well," Su Ping secretly jotted down these clues, and asked after a while: "You said that the autopsy has not been completed, what parts have not been done?" ”

"The main thing is the toxicology test," Lao Yan said, "The results have not come out yet, I plan to take some internal organs and make slices later, and observe them under the microscope."

There were no resistance injuries to the victim's body, and minor restraint injuries to the ankles, chest, abdomen, and neck were also posthumous. This is very strange, how can the deceased be killed if he is not bound? Unless, she ingests central nervous system depressants, or commits suicide. ”

He looked at Qi Yuan again and said, "At the scene, what Xiao Qi said also makes some sense.

The drag marks and trial incisions on the wound are not enough to illustrate the problem, and it may be that the murderer deliberately did it, or the murderer struggled to make up his mind when committing the crime, and could not fully make up his mind.

However, it is necessary to be quite cautious in making a suicide determination, so I intend to rule out the possibility that the drug may cause the victim to lose consciousness or resistance. ”

"I think it's not a small chance of suicide." Su Ping also glanced at Qi Yuan, and then said, "The corpse has been soaked in the bathtub for a long time, which is one of the evidences.

Normally, a day or two after the victim's death, the strong smell of corpses will begin to emit, and if it is a homicide, then it is time to consider throwing the corpse, rather than waiting for the corpse to evolve into a corrupt giant.

I am more inclined to believe that the body was found some time after the victim's death, and then the body was sunk into the sea. That is, it was discovered relatively early, otherwise I am afraid that a realistic version of the girl would have to be released, so she committed suicide for twenty days. ”

Qi Yuan couldn't help frowning: "But ...... If it is a suicide and the person who finds out that the victim is dead, shouldn't it be the police? He didn't kill people, so why should he throw corpses? ”

"I didn't understand that either." Su Ping shook his head slowly: "There is only one unreliable, general speculation - the suicide of the victim may have an important relationship with the corpse thrower." ”
