That's muscle spasms.

Yes, after the dissection of Li Fenglin's limbs, traces of muscle spasms were found.

Muscle cramps are hard to tell from the outside.

In particular, Fenglin died by drowning.

The characteristics of drowning death will cause corpses to appear earlier.

After the corpse corpse appeared, the corpse gradually began to stiffen and the muscles hardened.

In just an hour or two, the whole corpse is iron-like.

As a result, muscle spasms are hard to detect from the outside.

Further confirmation can only be done after an autopsy.

However, muscle spasms are only the direct cause of Li Fenglin's drowning death.

But the root cause of muscle cramps is that Li Fenglin has chronic arsenic poisoning.

Therefore, Li Fenglin's death was not an accident at all, but a deliberate murder.

Since it has been determined that Li Fenglin's death was not an accident, but an intentional murder, the next direction of handling the case is much simpler.

Since Li Fenglin was suffering from chronic arsenic poisoning, he could find clues as long as he checked the people around him.

Of course, the on-site investigation Li Hong was not spared at the time.

Li Fenglin came to swim after having lunch with friends outside at noon that day.

But I didn't drink while eating.

At the restaurant where Li Fenglin ate, Li Hong conducted an investigation at the time, and several friends who ate with Li Fenglin also conducted interrogations.

At that time, there were four people who ate with Li Fenglin, and the other four people had no other symptoms or symptoms, so the possibility of food poisoning was ruled out.

After that, Li Fenglin drank a bottle of water in Yongsheng Swimming Pool.

Li Hong tested all the drinks in the vending machine and found no arsenic.

The possibility of drinking water poisoning was also ruled out.

As for other people's poisoning...

This possibility is also very small.

When Li Fenglin was swimming that day, from the time he entered the swimming pool, except for changing his swimsuit in the locker room, he was always within the monitoring range.

In the middle, I only had brief contact with swimming coach Zhang Hong.

However, there was no physical contact between the two parties at the time, and no special behavior of Zhang Hong was found under monitoring.

It can be said that Li Hong's investigation at the time had ruled out the possibility of Li Fenglin's poisoning in the swimming pool.

The rest is easy.

Judging from the autopsy results, Li Fenglin has been suffering from chronic arsenic poisoning for a long time, at least a year.

In the past year, whoever is responsible for Li Fenglin's diet and daily life has the closest relationship with him, and whoever is the murderer of the poison.

For example, Li Fenglin's wife Zhao Linmeng.

Li Fenglin and Zhao Linmeng are married for the second time.

When Li Fenglin died, the two had been married for less than two years.

Moreover, when Li Fengming worked in coal mines in other provinces, he accumulated a lot of net worth.

Zhao Linmeng married Li Fenglin who was 49 years old at the age of 26.

Why?

For love?

Ha ha.

Li Fenglin is a typical middle-aged greasy uncle.

No hair, big belly, big yellow teeth.

Did not graduate from primary school, speaks rudely, and has a bad temper.

What about Zhao Linmeng?

With a beautiful appearance and a tall stature, he originally worked in a massage parlor opened by Li Fenglin.

To say that Zhao Linmeng and Li Fenglin got married for love, I'm afraid ghosts wouldn't believe it.

Therefore, if Li Fenglin died, then Zhao Linmeng would be the biggest beneficiary.

However, something strange happened.

Li Fenglin's autopsy report showed that he had various features of arsenic poisoning.

However, the autopsy detectives of the detective team did not detect any arsenic in Li Fenglin's body.

This is so fantastical.

When Li Hong knew that Li Fenglin's body had the characteristics of chronic arsenic poisoning, he even thought about the direction of the investigation of the case.

Zhao Linmeng was the first suspect.

However, you tell me now that no arsenic has been detected in Li Fenglin's body.

What does this mean?

Could it be that Li Fenglin metabolized all the arsenic in his body.

This is simply not possible.

All inorganic arsenic compounds can cause arsenic poisoning.

such as arsenic trisulfide.

Once this inorganic substance enters the body, it will be deposited in the body and cannot be metabolized.

Otherwise, if it can be metabolized, it means that the body cannot be poisoned.

Later, the Liancheng Detective Team even invited experts from the Liaoning Detective Brigade to examine Li Fenglin's body.

However, the result is the same.

No arsenic.

Li Fenglin's body was clean, and there was no arsenic residue at all.

Li Hong even conducted a detailed investigation of all Zhao Linmeng's shopping records.

Again, nothing was found.

In this way, the case was deposited and became an unsolved case.

Li Fenglin's body was not cremated back then, and is still frozen in the funeral home.

Chen Yan has studied the entire file three times.

Every word, every paragraph, Chen Yan analyzed carefully.

Along with the dossier are all the surveillance videos of Li Fenglin in the Yongsheng swimming pool at that time.

Chen Yan had turned on the visual gene lock, and carefully watched the video material twice.

It can be said that since Li Fenglin entered You Yongsheng Swimming Pool, every scene until his death has been brought into Chen Yan's mind.

During the whole process, Li Fenglin was not on the surveillance screen only when he entered the locker room to change his swimsuit.

Could it be that someone was doing tricks at that time?

However, only seven people were swimming in the swimming pool at that time.

When Li Fenglin came in, he was the last one.

These seven people, in addition to Li Fenglin, there are three men and three women.

Needless to say, women have separate locker rooms.

The other three men entered the swimming pool at least half an hour earlier than Li Fenglin.

From the beginning to the end, he never had any direct contact with Li Fenglin.

In the surveillance screen, Chen Yan carefully analyzed everyone's expressions and eyes.

The three men swimming had never looked at Li Fenglin.

Two of the men watched a young girl swim from time to time.

As for swimming coach Zhang Hong and lifeguard Yang Linsheng...

The probability of two people having problems is not very high.

Although Yang Linsheng got off the observation bench and drank a glass of water when Li Fenglin was drowning.

However, it was Yang Linsheng, a lifeguard, who first discovered that Li Fenglin had a problem.

In the follow-up rescue process, Yang Linsheng and Zhang Hong's eyes were very pure.

Cardiopulmonary resuscitation is very attentive and standard.

Obviously professionally trained.

From Li Fenglin entering the swimming pool to Li Hong leading the team to the police, Chen Yan found nothing suspicious.

Shaking his head, Chen Yan closed the file and picked up the phone.

"Liu team, is there anything in the afternoon?"

It was Liu Qingshan on the other end of the phone.

"It's okay, what, what instructions does Vice-Captain Chen have?"

During the phone call, Chen Yan smiled: "I don't have any instructions for you."

"I'm reading a drowning case in the team three years ago these days."

"There is really nothing suspicious in the dossier."

"In the afternoon, let's go to the funeral home?"

The drowning case three years ago?

Liu Qingshan's expression changed slightly Of course he knew about this case.

Not only does he know, but Liu Qingshan has also studied the entire case file many times.

Very clear on the ins and outs of the whole case.

However, as Chen Yan said, there is nothing suspicious in the dossier.

As for Li Fenglin's body, Liu Qingshan had just seen it when he took office in the first detective team.

"Okay, I'll pick you up later."

After hanging up the phone, Liu Qingshan packed up, took his work notes, and went straight out to pick up Chen Yan.

after an hour.

Northern suburbs funeral home.

Chen Yan saw Li Fenglin's body.
