That's muscle cramps.
Yes, after dissecting Li Fenglin's limbs, traces of muscle spasms were found.
Muscle cramps can be hard to see from the outside.
Especially Fenglin died of drowning.
The characteristics of drowning death will cause rigor to appear earlier.
After rigor mortis appears, the corpse gradually begins to stiffen, and the muscles harden.
After only one or two hours, the whole body will be like an iron plate.
In this way, muscle spasms are difficult to detect from the outside.
Only through autopsy can further confirmation be made.
However, muscle spasms were only the direct cause of Li Fenglin's drowning death.
However, the root cause of the muscle cramps was Li Fenglin's chronic arsenic poisoning.
Therefore, Li Fenglin's death was not an accident at all, but someone's deliberate murder.
Now that it has been determined that Li Fenglin's death was not an accident but a deliberate murder, the direction of the next case is much simpler.
Since Li Fenglin was suffering from chronic arsenic poisoning, as long as he checked people around him, he could find clues.
Of course, Li Hong did not let go of the on-site investigation.
Li Fenglin came to swim after having lunch with friends outside at noon that day.
But did not drink with the meal.
Li Hong investigated the restaurant where Li Fenglin ate, and several friends who ate with Li Fenglin also interrogated.
There were four people eating with Li Fenglin at that time, and the other four people had no other physical conditions or symptoms, so the possibility of food poisoning was ruled out.
Later, Li Fenglin once drank a bottle of water in the Yongsheng swimming pool.
Li Hong tested all the drinks in the vending machine at that time.
No arsenic was found.
The possibility of drinking water intoxication was also ruled out.
As for others poisoning...
This possibility is also very small.
When Li Fenglin was swimming that day, since he entered the swimming pool, except for changing his swimsuit in the locker room, he has been moving within the scope of monitoring.
In the middle, I only had brief contact with swimming coach Zhang Hong.
But there was no physical contact between the two parties at that time, and Zhang Hong did not find any special behavior under surveillance.
It can be said that Li Hong's investigation at that time has ruled out the possibility of Li Fenglin being poisoned in the swimming pool.
The rest is easy.
Judging from the autopsy results, Li Fenglin's chronic arsenic poisoning has been going on for a long time, at least a year.
Whoever was in charge of Li Fenglin's diet and daily life during the past year had the closest relationship with him, and whoever was the one who poisoned him might be the murderer.
For example, Li Fenglin's wife, Zhao Linmeng.
Li Fenglin and Zhao Linmeng are married twice.
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 wealth.
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.
Didn't graduate from elementary school, speaks rudely and has a bad temper.
What about Zhao Linmeng?
She has a beautiful appearance and a tall figure. She originally worked in the massage parlor opened by Li Fenglin.
If 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 investigators of the first detective team did not detect any arsenic in Li Fenglin's body.
This is so fantastic.
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 is the number one suspect.
However, you tell me now that no arsenic in Li Fenglin's body was detected.
What the hell does this mean?
Could it be that Li Fenglin metabolized all the arsenic in his body?
This is simply not possible.
All arsenides that can cause arsenic poisoning are inorganic arsenides.
For example, 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 Criminal Police Team even invited experts from the Liao Provincial Criminal Police Brigade to examine Li Fenglin's body.
However, the result is the same.
No arsenic.
Li Fenglin's body was clean, with no arsenic residues at all.
Li Hong even conducted a detailed investigation on all of Zhao Linmeng's shopping records.
Again, nothing was found.
In this way, the case settled down and became an unsolved case.
Li Fenglin's body was not cremated back then, and is still frozen in the funeral parlor.
Chen Yan has studied the entire dossier three times.
Every word, every paragraph, Chen Yan was analyzed in detail.
Together with the dossier, there are all the surveillance videos of Li Fenglin in the Yongsheng Swimming Pool at that time.
Chen Yan had activated the visual gene lock, and carefully watched the video material twice.
It can be said that every picture of Li Fenglin from entering You Yongsheng Swimming Pool until his death was brought to Chen Yan's mind.
During the whole process, Li Fenglin was not in the monitoring screen only when he entered the dressing room to change his swimsuit.
Could it be that someone tampered with it at that time?
However, there were only seven people swimming in the swimming pool at that time.
Li Fenglin was the last one when he came in.
Among the seven people, apart from Li Fenglin, there were three men and three women.
Needless to say for women, their dressing room is separate.
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 monitoring screen, Chen Yan carefully analyzed everyone's expressions and eyes.
The three men swimming never looked at Li Fenglin.
Two of the men watched a young girl swimming from time to time.
As for swimming coach Zhang Hong and lifeguard Yang Linsheng...
The probability that two people have problems is not too high.
Although Yang Linsheng got off the observation bench to drink a glass of water when Li Fenglin was drowning.
However, lifeguard Yang Linsheng was the first to discover that there was something wrong with Li Fenglin.
During the follow-up rescue process, Yang Linsheng and Zhang Hong's eyes were pure.
Cardiopulmonary resuscitation is very careful and standard.
Obviously professionally trained.
From when Li Fenglin entered the swimming pool to when Li Hong led the team out to the police, Chen Yan didn't find anything suspicious.
Shaking his head, Chen Yan closed the file and picked up the phone.
Captain Liu, do you have anything to do this afternoon?
It was Liu Qingshan on the other end of the phone.
It's okay, what's the matter, what instruction does Deputy Captain Chen have?
During the phone call, Chen Yan smiled: I don't have any instructions from you.
In the past two days, I've been watching a copy of the drowning case in the team three years ago.
There is really nothing suspicious in the file.
In the afternoon, shall we go to the funeral parlor?
The drowning case three years ago?
Liu Qingshan's expression moved slightly.
Of course he knew about the case.
Not only did he know that Liu Qingshan had also studied the entire case file many times.
The ins and outs of the whole case are very clear.
However, as Chen Yan said, there was nothing suspicious in the dossier.
As for Li Fenglin's body, Liu Qingshan went to see it when he first took office in the Detective Division 1.
Okay, I'll pick you up later.
After hanging up the phone, Liu Qingshan tidied up, took his work notes, and went straight out to pick up Chen Yan.
after an hour.
Northern Suburb Funeral Home.
Chen Yan saw Li Fenglin's body.
