We didn't get any useful new clues from Yao Xun'an, and the information he gave us was what we already had.

In the three years of the "Seven Dragons and One Phoenix" small team, there were more than 20 "honest" classmates who bullied on campus, and Chu Ming was the most seriously bullied.

They blocked Chu Ming in the men's restroom and beat him, cut his hair with scissors, destroyed his stationery and poured ink on his homework book.

Chu Ming will report the situation of his bullying to the homeroom teacher Liu Huiling, and the teacher will also educate and find the parents of the students who participated in the bullying. As Teacher Liu said, after many conversations and education, four of the eight-member team of "Seven Dragons and One Phoenix" no longer participate in school bullying.

Yao Xun'an is a key figure in the school bullying gang, and he will leave the city in two days, and the murderer will definitely seize this opportunity to take action against Yao Xun'an.

I have ordered the criminal police team to eliminate the capable police officers, and to monitor Yao Xun'an 24 hours a day.

When Li Meng and I returned to the office of the Serious Crime Team, Jiang Tingbai had just returned from the Trace Examination Section.

"Lao Qin, you're back, I just have something to tell you." When he saw me, he walked up to me and said to me very anxiously.

"Found out?!" I asked him seriously.

Jiang Tingbai nodded and said to me: "I just led the team to compare all the fingerprints and footprints found in Hu Yuanling's house, in addition to the police and emergency doctors who entered the scene, I also found a person's fingerprints and footprints, which are likely to be left by the murderer!" ”

"Where in the room were the footprints found?!" I immediately asked.

"It was found in front of Hu Yuanling's house, the footprints and fingerprints were all at the door, and the same was not found elsewhere in the room." Jiang Tingbai looked at us and said in a deep voice.

This is definitely a major discovery and a major breakthrough in this case!

As long as we compare the fingerprints and footprints of all the 28 people who attended the class reunion, we can find the murderer!

Thinking of this, the corners of our mouths can't help but rise.

Now, it's really time to clear the clouds and see the moon!

At this time, Li Meng suddenly asked Jiang Tingbai: "Is it compared with the footprints found on the rooftop?" ”

Jiang Tingbai nodded and said seriously: "It has been compared, but the footprint on the rooftop is more blurry, it is a footprint with a shoe cover, but after comparison, these two footprints are forty-two yards." ”

I nodded, pondered for a moment, and asked a key question: "Did it compare with the fingerprints and footprints of Chu Ming that we brought back?" ”

Jiang Tingbai took a deep breath, spit it out slowly, nodded and said to us: "I have also compared, Chu Ming is not the murderer in this case, although he has the motive and time to commit the crime, he is indeed not the murderer." ”

It seems that Chu Ming really didn't lie, he did no longer hold a grudge against this school bullying gang that bullied him back then, and he was relieved.

So far, Chu Ming has truly cleared his suspicions.

Then, Jiang Tingbai added: "We have compared the fingerprints and footprints collected from the members who participated in the class reunion that everyone investigated recently, and none of them are the murderers in this case." ”

At this time, the murderer has been reduced by half from the range of twenty-eight people!

That's exciting news!

While I was happy, I suddenly thought of something: "Li Meng, didn't you collect Yao Xun'an's footprints and fingerprints?" ”

Li Meng came back to his senses and nodded in response: "Yes, yes, yes!" ”

She hurriedly took out the collected footprints and fingerprints and handed them to Jiang Tingbai, and handed them to him to take to test the Kobe Bryant.

After Jiang Tingbai left, Li Meng and I looked at each other and smiled, and we both breathed a long sigh of relief.

This time, the murderer is really not far from us.

We will bring him to justice soon.

The reason why we are so sure that the fingerprints and footprints are the murderer's is because the fingerprints and footprints appeared at the door of Hu Yuanling's house, and Hu Yuanling's backpack was hung at the door of the house.

Therefore, it is very likely that this was left by the murderer when he secretly exchanged the medicines in Hu Yuanling's backpack.

"However, we did not collect fingerprints other than Hu Yuanling on the white medicine bottle, which shows that the murderer was wearing gloves when changing the dressing, but why did the fingerprints be collected elsewhere? Also, when the murderer committed the crime on the rooftop, he was wearing shoe covers, why did he leave clues so carelessly this time? I muttered.

This is indeed a major suspicion in this case, and it is also a major suspicion that affects the closure of the evidence chain in this case.

"Maybe the murderer came in a hurry this time and forgot to wear it, after all, breaking into the house to change drugs is to find the right time. Moreover, Hu Yuanling has taken blood pressure medicine for so many days, and the fingerprints on the medicine bottle have long been erased. Li dreamed about it and explained it to me seriously.

I nodded, maybe that's a reasonable explanation.

The murderer is about to be caught, and the case is coming to an end, and all of us are full of energy to add the last fire to the realization of this serial murder case.

About half an hour later, Jiang Tingbai happily ran into the office of the serious crime team, and almost slipped under his feet.

I've known him for so long, and I haven't seen such an excited smile on his face.

"Old Qin! Lao Qin! ”

"Locked up the murderer?!" I quickly stood up and asked seriously.

Jiang Tingbai nodded vigorously and said very excitedly: "Who is the footprint and fingerprints you collected today?!" ”

"He is one of the members of the 'Seven Dragons and One Phoenix' school bullying gang, called Yao Xun'an!" Li Meng immediately answered.

"He's the murderer! The fingerprints and footprints are exactly the same, and they are exactly the same as the stride length deduction and height and weight estimation I did! Jiang Tingbai shouted excitedly.

"Inform the criminal police team! Arrest Yao Xun'an immediately! I ordered.

At the gate of the Ningzhou Public Security Bureau, two police cars started and sirens roared, gradually moving away.

I stood at the window of the office of the Serious Crime Unit, looking at the police cars in the distance, but my heart did not light up at all.

Yao Xun'an was the murderer, which surprised me very much.

Because we have always been absolutely Yao Xun'an is the next victim in this case, the murderer is taking revenge on this school bullying gang called "Seven Dragons and One Phoenix".

If Yao Xun'an is the murderer, then what is his motive for killing?!

Why did he kill his junior high school classmates, his former brother, and his first love Hu Yuanling.

This is a key suspicion, and it is also a key factor affecting the closure of the chain of evidence.

But now that the evidence is overwhelming, the motive for the murder is waiting for him to tell us personally......
