Will Liu Mei poison Zhu Fengfan in order to get the insurance money?

Lao Ji assumed that Liu Mei and Liu Song conspired to pick up Zhu Fengfan together, poisoned him in the car, and then drove the car to the bridge, threw the body off the bridge while no one was around, and then escaped.

Xiao He said that there were no suspicious clues found in Liu Song's car, and Sister Xi said that when she poured, she felt that Yueyue was very suspicious, and her mobile phone was turned off all the time, as if the world had evaporated.

At this time, a police officer reported that Yueyue's number was in use, and the technical investigation department had locked the number, which was near the University of Technology.

The police found the user of the number, who was a college student, and he said that the calling card was his, but when Cuong asked him what his relationship was with Zhu Fengfan, he said that he did not know Zhu Fengfan.

Under Ah Qiang's questioning, he admitted that he had picked up the phone card under the teaching building, and he found that there were still dozens of dollars to spend in it, so he used it himself.

It takes a certain amount of time for Xiao He to peel off his fingerprints from the phone card, and after Lao Ji asked him to peel them out, he first compared Zhang Ji's fingerprints.

He thinks that Zhang Ji is the most suspicious, because the college student is from the same school as Zhang Ji.

This time, Zhang Ji came to the police station, and he still had a wound on his head, and he said that Liu Song beat him. Zhang Ji said: Since he fell in love with Liu Mei, Liu Song looked at him unpleasantly, and later he separated from Liu Mei, in addition to Zhu Fengfan, there is also Liu Song's credit.

Because he saw so many things happening in Liu Mei's family, he wanted to care about Liu Mei, but Liu Song just didn't let them meet and pushed him down.

Lao Ji asked Zhang Ji who Yueyue was, but Zhang Ji said that he didn't know Yueyue.

Lao Ji said: Now Yueyue's mobile phone card has been found, and his fingerprints have been detected on it.

Zhang Jicai confessed that Yueyue was actually pretended to be him, and he was forced to break up because he was misunderstood by Liu Mei. And what caused this misunderstanding was a mysterious text message.

He said that this was similar to Yueyue, it was sent by a lover who didn't exist at all, and he was later discovered by Liu Mei, and he didn't listen to my explanation.

Later, coupled with Zhu Fengfan's intervention, the two finally broke up. He thought that Zhu Fengfan did all this, so he used the same method to retaliate against Zhu Fengfan.

The night of Valentine's Day was the text message he sent to Zhu Fengfan, and that day also happened to be Liu Mei's birthday, and he wanted to use this to disgust Zhu Fengfan.

The police held a case analysis meeting, and Lao Ji asked: If Zhu Fengfan dies, who will benefit.

Sister Xi replied: I wish Fengfan's competitors, heirs of the estate and insurance beneficiaries.

Lao Ji analyzed the contradictions between competitors and him, it should not have intensified to the point of killing, as for the heir to the inheritance, his daughter was poisoned, his son was just out of danger, and Zhu Fengfan was bankrupt.

Originally, they didn't have much hope, so the biggest suspect left should be Liu Mei, if Liu Mei is the murderer, then she must still have a conspirator, because Liu Mei can't drive and can't complete the body alone.

Then the conspirator should be Liu Song or Zhang Ji, or the three of them co-starred in such a scene. Lao Ji planned to talk to Liu Mei and Liu Song respectively to see if they could find loopholes in their testimony, and then try to obtain the DNA of the two of them and the DNA extracted from the lockbox.

If the comparison has nothing to do with them, it can only be expanded among Zhu Fengfan or Liu Mei's acquaintances for DNA comparison.

Subsequently, police officers reported that Liu Mei had been disfigured with sulfuric acid and hospitalized. The doctor said that Liu Mei was only slightly injured, probably because the person who poured the sulfuric acid was soft or the victim avoided it in time, and the sulfuric acid splashed on the face was very small.

Faced with the police's questioning, Liu Mei said that the murderer covered her face, and she ran away as soon as she shouted. Lao Ji asked Sister Xi to call Xiao He and asked him to investigate the scene and try to find the sulfuric acid bottle.

At this time, Liu Song walked in, and he said to Liu Mei: No matter what she will become, he will take good care of her for the rest of her life. Liu Mei's expression was a little weird, and she didn't want to talk to him.

The case became more and more complicated, first Zhu Fengfan was killed, then Zhu Fengfan's children were poisoned, and now Liu Mei was disfigured again.

Lao Ji believes that from the analysis of relevant evidence, this series of cases should have been done by one person, so what is the purpose of this person.

Lao Ji speculated that this person should be Zhu Fengfan's enemy, and his goal was to hurt Zhu Fengfan and his relatives one by one, but no such person has been found yet.

People who usually have conflicts with Zhu Fengfan have taken the initiative to stand up and provide their DNA and fingerprint samples, and now they are about to test Liu Song's DNA and fingerprint samples.

But Lao Ji and Ah Qiang both felt that it was unlikely that Liu Song would commit the crime, which was Lao Ji's accidental discovery in the information that the age difference between Liu Mei and Liu Song, the sister and brother, was only two months, which made Lao Ji very puzzled, and he asked Ah Qiang to go to the police station immediately to verify.

Soon Ah Qiang found out that Liu Mei and Liu Song were not related by blood at all, they were both adopted from orphanages, and their adoptive parents were infertile, which explains why the siblings' birthdays were only two months apart.

This discovery gave Lao Ji a new idea, and then Liu Song received a notice to come to the police station, this time informing him that he was coming to collect his DNA and fingerprint samples, and Liu Song's expression was not very good-looking.

In the evening, Liu Song went to the hospital to visit Liu Mei, and he asked Liu Mei if she had seen the person who poured her sulfuric acid, Liu Mei shook her head, but Liu Mei said that she had seen the person's back clearly, and she was too familiar.

Liu Song asked who she was, but Liu Mei refused to say it, and the person who poured sulfuric acid was Liu Song in front of her.

Liu Mei said: "I just want to ask him why and why Liu Song"

Liu Song said: "Sister, that's all because I love you, and I want you to come back to me." ”

Liu Mei suddenly felt ridiculous when she heard this, how could her younger brother fall in love with her sister, and then she realized that her previous marriage was all destroyed by the younger brother in front of her.

Faced with Liu Mei's questioning, Liu Song denied that he had killed Zhu Fengfan and poisoned the food, Liu Mei scolded Liu Song away, and then made a phone call to the police station.

Sister Xi and Xiao He came to Liu Song's residence, and the walls were full of photos of Liu Mei. Xiao He has confirmed that the fingerprints on the sulfuric acid bottle belong to Liu Song, and now the DNA results have not yet come out, but it is almost certain that Liu Song is the murderer of these cases.

Xiao He found a toolbox next to the table, and on the screwdriver inside, he found some black substance.

After testing, the person who pried open the lockbox was Liu Song, which surprised everyone, Liu Song did not find any traces in his car, Xiao He guessed that he should have washed the car and changed to a new cushion.

At this time, Lao Ji realized that the loophole they ignored at the beginning, that is, Liu Song went to pick up Zhu Fengfan, but he didn't receive it, but he never called to contact him, and the focus of his suspicion at the beginning was on Zhang Ji, and he ignored his suspicion of Liu Song.

Lao Ji ordered Liu Song's immediate arrest, but when the police arrived at Liu Song's house, he had already fled.

Late at night, Liu Song was bold and came to Liu Mei's ward again, he came this time to express his love for Liu Mei, but Liu Mei did not accept it.

Liu Song took out the bottle of potassium Q that poisoned Zhu Fengfan, he wanted to die to prove his love for Liu Mei, and later drank it in front of Liu Mei.

Liu Mei recounted the whole process to the police, and after sending Liu Mei away, Sister Xi doubted the authenticity of Liu Mei's testimony, she suspected that Liu Mei's sister and brother murdered Zhu Fengfan for insurance, and finally Liu Mei killed Liu Song in order to kill her.

But Lao Ji said that the scene in the hospital ward showed that Liu Song had indeed committed suicide. Sister Xi also has one of the biggest questions, why did Zhu Fengfan steal potassium.

Lao Ji analyzed: Zhu Fengfan's company is bankrupt, entangled in lawsuits, he is preparing to commit suicide, in combination with the note in the lockbox and Zhu Fengfan's frequent public humiliation of Zhang Ji's abnormal phenomenon, Zhu Fengfan is likely to blame Zhang Ji for his death, the purpose of this is to fear that after Liu Mei gets insurance, Zhang Ji will get a piece of the pie, and the hospital's test sheet shows that Liu Mei has been suspicious for three months, which Zhu Fengfan cannot not know...
