Judging from Liu Qingqing's learning that Gu Chengjun was killed, she likes Gu Chengjun very much. Could the murderer have poisoned him because of this?

Jiang Yanxuan made a bold speculation that Gu Chengjun's murder was likely to be related to Liu Qingqing, and he decided to re-investigate Liu Qingqing's social relations.

Soon, a person named Gao Yuanhong appeared in the sight of the police. Before Liu Qingqing met Gu Chengjun, she also had a lover, named Gao Yuanhong, but this Gao Yuanhong left her place of residence the day after Gu Chengjun was killed, and no one could contact him.

This Gao Yuanhong also used to do mountain goods business with her, but after slowly getting in touch for a long time, Liu Qingqing found that Gao Yuanhong was very narrow-minded and possessive, and had interfered with her normal life.

Usually when men get a little close to Liu Qingqing, he will eat flying vinegar indiscriminately, and often lose his temper inexplicably.

Although Liu Qingqing and Gao Yuanhong have an ambiguous relationship, she has never thought about divorcing Monsoon. However, Gao Yuanhong would often come to her when Monsoon was at home, which caused Liu Qingqing's strong dissatisfaction.

"I'm annoyed with him, and I'm afraid of pestering me." Liu Qingqing held the teacup and seemed to want to calm down the temperature of the tea, "He should also know something about me and Gu Chengjun, just two months before Gu Chengjun was killed, not long after my brother and sister and I lay down, he broke into my house. ”

Her hands kept shaking, as if she was recalling some terrifying scene, "As soon as he came in, he said to me, 'I know the relationship between you and Gu Chengjun, and I hope there will be no more contact between you and him.' And with that, he left. ”

Liu Qingqing avoided the important and lightly recounted, but judging from her series of performances, Gao Yuanhong should not let her go so easily that night, a man with such a strong possessiveness will not give up after learning that his property has been encroached upon.

Lin Hui and the others drove to Gao Yuanhong's house, and his family told him that Gao Yuanhong had gone to other provinces to see his daughter in college.

This reason made Lin Hui feel a little too far-fetched. Normally, the school has just opened, and the daughter who has just come home from the holidays should not fly to other provinces to see the children in the near future without special reasons.

What's more, Lin Hui and the others found that Gao Yuanhong's mobile phone had no way to connect. Normally, a person who is away from home should keep his mobile phone on and keep in touch with his family, so that Gao Yuanhong's suspicion is even deeper.

However, according to Gao Yuanhong's younger brother, at about 11 o'clock on the night of Gu Chengjun's murder, he once saw his brother at home, which can prove that his brother was at home during that time, so Gao Yuanhong should not have the entire activity trajectory of the time of the crime.

However, just relying on Gao Yuanhong's younger brother's words, there is no other circumstantial evidence, as long as this case is not solved, Lin Hui and they dare not easily rule out his suspicion.

If they want to investigate the suspicions on Gao Yuanhong, the first thing Lin Hui and they have to do is to find Gao Yuanhong himself.

Whenever Jiang Yanxuan was lying on the bed in the dead of night, he would always be cranky, often insomnia, and couldn't help but want to communicate his thoughts with Lu Guan.

Lu Wan would listen to it every time and fall asleep, but he couldn't sleep.

The temperature of the air conditioner was turned on a little high, and fine sweat spots oozed from Lu Guan's forehead, Jiang Yanxuan gently wiped him off with his sleeve, wanting to treat a supreme treasure like he was afraid of disturbing his sweet dream.

After wiping it and lying back with nothing to do, quietly looking at the person in front of him, his heart was inexplicably quiet, all his troubles were left behind, and then he fell asleep deeply.

Gu Man's strange dream, the special relationship between Liu Qingqing and Gao Yuanhong and Gu Chengjun, and the awkward position of Liu Qingqing's husband all made this case particularly complicated.

After Jiang Yanxuan and the others combed through all the clues they knew so far, they decided to open this breakthrough in Liu Qingqing, because Lu Guan observed that Liu Qingqing's expression was not so much about whether her relationship with Gu Chengjun was exposed, but more about whether her husband was a murderer.

As a key figure in a murder case, Lu Guan dared to assert that Liu Qingqing must have hidden something from them.

Faced with Jiang Yanxuan's questioning again, Liu Qingqing finally said a detail that she had been worried about.

"I recently discovered that two knives in my house suddenly disappeared." Liu Qingqing said.

In this case, the victim was injured by a sharp object. Just two months before the crime, she had seen her husband Ji Feng put two knives in his closet, but after Gu Chengjun's accident, when she sorted out the wardrobe, she found that the knives in the closet were missing.

Liu Qingqing stammered a little when she spoke, "I didn't say it before, it's that I'm really afraid that my husband is a murderer, police officer, believe me, I'm innocent." ”

"Whether this matter has anything to do with you, whether it has anything to do with your husband or not, it still has to go through a follow-up investigation, I hope you don't hide anything from us in the future investigation, as long as this matter has nothing to do with you, knowing everything is the best proof to yourself."

Liu Qingqing lowered her head and said, "Okay, I understand." ”

Jiang Yanxuan and the others immediately found Monsoon, but Monsoon denied that he owned two knives. They were now wondering why Monsoon was hiding the fact that he had two knives, which was really unnecessary if he had a clear conscience.

So they thought about it, could these two knives be murder weapons, and they would be hidden after committing the crime?

The suspicions he learned before the integration, the fact that Ji Feng concealed the fact that he had two knives, and more importantly, he worked as a railway, and he was not familiar with the environment next to the railway, and there was no alibi on the night of the crime, combined with the strange dream of Gu Chengjun's sister Gu Man, Jiang Yanxuan and they suddenly had a bold guess.

Could it be that Ji Feng found out about the scandal between Liu Qingqing and Gu Chengjun, and then began to decide to kill Gu Chengjun. Ji Feng, who took over the shift with his colleagues that night, sat alone in the office, and the more he thought about it, the more angry he became, so he drove to the door of Gu Chengjun's house and waited, and then killed Gu Chengjun and threw Gu Chengjun's body into the sand pit dug in advance.

He calculated the right time and place, but he missed the people, what he didn't expect was that Gu Chengjun's sister Gu Man actually came to find Gu Chengjun, and then went around to inquire about Gu Chengjun's whereabouts, and overheard that it was the monsoon that killed Gu Chengjun.

So Ji Feng began to beg Gu Man not to tell this matter, begging her to forgive her for not doing it on purpose, and gave Gu Man a large sum of money.

Gu Man, who came back to her senses, felt that her younger brother had been brutally killed, and it was really unbearable to throw his body in the wilderness, so she had to tell the police where her brother was buried in a dream, so that her heart would be a little better.

But the monsoon here denied it, saying that he didn't know the relationship between his wife and Gu Chengjun at all.

"My relationship with Gu Chengjun has always been good, usually I have little time at home, so I ask him to help me take care of Liu Qingqing, but I didn't expect him to take care of me to bed. Officer, I really don't have two knives, but I have two green hats, my life is miserable......" Ji Feng, the eight-foot man, burst into tears, and almost didn't give Jiang Yanxuan advice to give a dozen beers to quit drinking and dispel his sorrows.

Just when Ji Feng didn't admit it, Ji Yun, Ji Feng's younger brother, gave them a clue.

He said that his brother once secretly gave him a package for him to keep one night after Gu Chengjun was killed, so that he could not pass it on. Ji Yun opened it curiously and found that there were two steel knives inside.

"After I heard that Gu Chengjun had an accident, I have been worried about the problem of the two knives, no, I want to be a good citizen in the new era, and immediately come over and report to the police officers non-stop!"

"Thank you, comrade." Lin Hui took the two steel knives brought by Ji Yun and carefully asked people to send the knives to the trace examination room.

"Hey, officer, is there any reward for providing clues?" Ji Yun rubbed his little hands excitedly, if he had a tail, he would definitely be shaking happily now.

Lin Hui ruthlessly said to him, "There is no reward, verbal praise will come as soon as you open your mouth, which sentence do you want to hear?" ”

Ji Yun pursed his lips and said something boring, and then ran to the reception to chat with Xiao Liu.

On the other side, Lu Wan was even more puzzled in the face of Ji Yun's handover of these two knives.
