The two steel knives sent by Ji Yun, the surface of the knives was very clean, Lu Guan took a wet cotton swab to wipe it, and found that there was no dust on it, as if it had just been treated.

When Ji Feng handed the knife to his younger brother, he must have touched the knife, but he couldn't find a single fingerprint on the knife.

Ji Feng's explanation for this is "When I handed over the knife to my brother, I was afraid that the police would suspect that I killed Gu Chengjun with Liu Qingqing, because the camouflage uniform was found near my house, and my daughter-in-law was relatively close to Gu Chengjun. ”

After a large number of visits and investigations by the investigation team, although Jiang Yanxuan and the others had no evidence to prove whether Monsoon had been on duty in the unit that night, at least they could be sure that Monsoon and Gu Chengjun's sister Gu Man had not met.

Lu Guan's identification results of the two knives also came out, the wounds caused by the sharp weapons did not match the wounds on Gu Chengjun's body, and no bloodstain reaction was detected on the knife, so the two knives were not the murder weapons that killed Gu Chengjun.

Although there is no conclusive evidence to prove that Ji Feng killed Gu Chengjun, Ji Feng's two knives belong to controlled knives, and according to the laws of our country, individuals are not allowed to possess controlled knives privately, so Jiang Yanxuan confiscated it and detained Ji Feng for public security.

The eight-foot man who learned the news, Ji Feng, cried to death, pulled the corner of Jiang Yanxuan's clothes and begged him not to confiscate it, "Officer, you can lock me up, but I beg you, can this knife not be confiscated?" This is the real knife I bought from Japan with the private money I have saved for a long time, and you are going to ruin my years of hard work all at once! ”

Jiang Yanxuan is just like Bao Qingtian now, his black face is selfless, and he ruthlessly confiscated it according to law.

Lu Wan came to Jiang Yanxuan's side and asked him, "Does my brother also collect private money?" ”

Jiang Yanxuan immediately coaxed, "No, no, I resolutely dare not have!" ”

Lu Wan nodded with satisfaction.

Lin Hui on the side didn't think it was a big deal to see the excitement, "As the saying goes, a man's mouth is a deceitful ghost, sister-in-law, don't be deceived by him so easily." ”

Although everyone in the police force knew about Jiang Yanxuan and Lu Guan, it was the first time that he was called sister-in-law Lu Guan in person, and his face immediately turned red, and then he punched Jiang Yanxuan, "You better not lie to me!" ”

"Wronged! I really don't dare to have it! Jiang Yanxuan coaxed good-naturedly, and the black-faced Bao Qingtian just now disappeared without a trace.

Lin Hui sneered, and was met with a white eye from Jiang Yanxuan, but because his sister-in-law just now was very useful to Jiang Yanxuan, the mad demon of Xuan's wife, and his tail was going to rise to the sky, he couldn't wait for the whole world to know that Lu Guan was his exclusive product.

However, Jiang Yanxuan didn't make Lin Hui feel too good.

Because the current clues have stagnated, Jiang Yanxuan sent Lin Hui to follow up on the investigation of another suspect, Gao Yuanhong.

"Team Chiang! That place is so far away, can you be reimbursed if the ticket is so expensive? Lin Hui asked.

"Of course not." Jiang Yanxuan glanced at him, "But the leader of the train will still be reimbursed." ”

Everyone knows that it takes at least ten hours to get to that place by train from S City, and you can sit flat on your ass.

"Is it okay to have high-speed rail?" Lin Hui still has a trace of luck.

Jiang Yanxuan was selfless with an iron face: "No." ”

Up to now, Ji Feng, Liu Qingqing, Gao Yuanhong, and even Gu Chengjun's sister Gu Man have all been suspected and investigated by Jiang Yanxuan.

But now, Liu Qingqing's suspicion seems to be the smallest, Ji Feng has been detained, and Gao Yuanhong still has no news.

More than half a month has passed since the incident, and Jiang Yanxuan and the others still have no new progress, so that for a period of time, Jiang Yanxuan didn't dare to run to Lu Guan's office to ask for hugs and praise as before, for fear that Lu Guan would ask him about the progress of the case, but he replied, "No, there is no progress now." ”

Because men can't say they can't.

So Jiang Yanxuan planned to adopt another reconnaissance method, saying to the outside world that the case had been solved.

The already frustrated police officers unanimously agreed to the proposal.

"Let's be a dead horse doctor, as long as the murderer shows his feet, we will win." Jiang Yanxuan said.

Jiang Yanxuan felt that if the murderer in this case was Gao Yuanhong, then he threw the bloody camouflage uniform near Ji Feng's house, and it was very likely that he wanted to frame them.

Therefore, he was ready to push the boat down the river, communicated with Liu Qingqing's family and Ji Feng himself, declared that Ji Feng was the suspect, and then arrested him.

After discovering Gu Chengjun's body, Gao Yuanhong has not been heard from, and what everyone didn't expect was that three days after the police spread the news that the case had been solved, Gao Yuanhong, who had been missing, came back.

Gao Yuanhong's suspicion is getting heavier and heavier, but so far Jiang Yanxuan has not been able to find evidence that he killed directly.

The evidence will always be there, and it won't go, it's just that the scouts need to find him little by little.

The hard work paid off, and finally, when the investigation team was investigating and visiting the residential area, they got a piece of news.

A neighbor had a wheelbarrow at home, which was borrowed by Gao Yuanhong on the night of the crime.

"That night he said he was going to carry sand, so he took it and borrowed it." Uncle Huang, an enthusiastic citizen, handed the police this clue.

The scout immediately sensed a strange place, how could anyone carry sand at night?

There were no street lights in the first place, and there were not many people. Especially at night, it's pitch black, and you can't see anything, it's very eerie.

Uncle Huang, an enthusiastic citizen, continued, "There is even more strange, he returned the car to me during the day the next day, and the car was still clean, and I praised him at that time as a qualified four good citizens!" ”

Jiang Yanxuan immediately doubted, could this wheelbarrow be a tool for transporting corpses? Then the car was immediately inspected.

Soon, a few drops of blood were found on a piece of film at the bottom of the wheelbarrow's body.

After testing, these bloodstains were the deceased Gu Chengjun's.

In this way, Jiang Yanxuan and the others have a direct evidence that Gao Yuanhong used this wheelbarrow to contact the deceased.

Although a bloodstained wheelbarrow could not be sufficient evidence of Gao Yuanhong's murder, Jiang Yanxuan and the others decided to directly contact Gao Yuanhong.

However, in the face of interrogation, Gao Yuanhong did not admit that he killed Gu Chengjun.

A wheelbarrow alone could not determine that he had killed someone, so after getting a search warrant, Jiang Yanxuan conducted a careful search of Gao Yuanhong's house.

This time, they found a plastic bag at the bottom of a simple bathing shed in the courtyard of Gao Yuanhong's house, which contained two bloody sharp knives.

After the murder weapon was extracted, there was indeed a little mottled blood stain on it, and after it was sent for inspection, it was compared, and it was finally confirmed that this was a bloodstain belonging to Gu Chengjun.

The sharp weapons hidden in the house had traces of the deceased's blood, and the borrowed wheelbarrow also had the blood of the deceased, and in the face of this kind of evidence, Gao Yuanhong confessed to the fact of killing Gu Chengjun.

During the interrogation, Gao Yuanhong told the police that he liked Liu Qingqing very much, and he felt that Gu Chengjun's appearance caused him and Liu Qingqing to break up.

Gao Yuanhong is very possessive, thinking that Liu Qingqing is his own person if he follows him, but since Gu Chengjun appeared, he can clearly feel that Liu Qingqing's whole person is put on Gu Chengjun, and then farther and farther away from him.

After Gao Yuanhong made the decision to kill Gu Chengjun, he found a place to bury his body in advance.

On the night of the crime, Gao Yuanhong came to Gu Chengjun's house with a knife, but Gu Chengjun was not at home.

Just as he was about to act another day, he ran into Gu Chengjun, who had just come out of Liu Qingqing's house, and he was immediately furious and rushed forward.

"After I saw him, I stabbed Gu Chengjun a few times with a relatively narrow single-edged knife in my hand, and then he faced me and retreated, fighting me as he retreated, and then he fell to the ground. He continued to fight me after he fell to the ground, and the dress was supposed to be kicking around like that and then it was going somewhere else, and it was so dark that I didn't notice it. ”

Gao Yuanhong looked directly into Jiang Yanxuan's eyes, recounting this terrible scene word by word, but there was no trace of regret in his eyes.

Gu Chengjun was not dead when he fought with Gao Yuanhong, and his strong desire to survive made him endure the severe pain and stood up and ran to the sand near his house, Gao Yuanhong was afraid of being discovered by the people around him, so he hurriedly ran up to make up for him a few times, Gu Chengjun finally remained motionless, and a large amount of blood flowed down the gap to the inside.

Gao Yuanhong, who killed the red eye, finally calmed down a little, and then went home to get the wheelbarrow and digging tools.

As he was tumbling in the yard, his brother came out of the house, and he saw him in the night, but he did not see the mottled blood on his body.

After further investigation, it was found that the entire crime process was committed by Gao Yuanhong alone, which was really just a coincidence.

In Lu Guan's words, "We human beings are still too small, and there are too many things that cannot be solved by one science." ”

Gao Yuanhong, who told the whole story of the crime, looked at the only window in the interrogation room, suddenly burst into tears, and muttered: "I really love her very much......
