Mystery Tracker 2

July 7, at 5:[-] pm.

S City Police Department.

Hearing the news that the autopsy found something, Shen Yan immediately led the team back to the S city police station.

"How? What clues did you find?" Shen Yan asked as soon as he entered the office of the forensic team.

Jiang Ruiheng and Cheng Jinsong were sitting in the office. When they saw several people from the serious crime team coming in, Jiang Ruiheng got up and said, "Then let me tell you the good news first. We re-examined the two bodies and found that the second victim Liu Dan bit the murderer before he died. By re-sampling the mouth of the deceased, we extracted two different DNAs, one belonging to the victim Liu Dan, and the other belonging to a male." Jiang Ruiheng said.

While he was speaking, he also handed Shen Yan a test sheet.Several people from the serious crime team gathered together and saw a series of complicated data on the long laboratory test sheet. Knowing that everyone might not understand it, Cheng Jinsong explained aloud: "This is the STR typing test, and the test is The number of alleles on the same locus, the final conclusion is 4, which means that there are 4 alleles at this locus, and each person should have two alleles, and now there are 4 alleles, it means The DNA in the sample is from at least two people."

"Hey, it doesn't matter whether you understand it or not," Qin Kai said joyfully, "The important thing is to find out! It's easy to check later!"

However, Shen Yan's expression was not as excited as his, because what Jiang Ruiheng said just now was "tell the good news first".He put down the test sheet, looked at Jiang Ruiheng and asked, "Is there any bad news?"

"The bad news is that Jinsong and the others have already compared the unknown DNA in the system, but no match was found." Jiang Ruiheng spread his hands.

After Jiang Ruiheng said this, the excitement of the serious crime team suddenly became a little less.

"Our current database mainly collects data on the population in the city, and there are not many in the surrounding counties and towns." Cheng Jinsong explained, "But with the discovery of Ruiheng, there are more things we can do here. The Yunxi County Police has kept a large number of evidence at the scene of the crime, we can now compare it based on the target DNA, and maybe we can find new discoveries from those evidence."

Shen Yan nodded: "Then I've worked hard for you these few days, let us know immediately if you find anything."

"Okay." Cheng Jinsong nodded, looked at the slightly tired looks of several people, and asked, "How is it? Did you find anything there?"

Fang Liyuan shook his head: "The Yunxi police have already checked several conventional lines. Cao Jinsheng has never had any feud with anyone, and the two victims have never had any conflicts with anyone—in fact, we think the murderer's main purpose is to Seeking money, but regarding the point of 'why the murderer chose Cao Jinsheng's guest house', the Yunxi police are only speculating that Cao Jinsheng's store is doing good business, but they are not completely sure."

"Maybe it's because his house is so easy to steal," Cheng Haiyang interjected, "I haven't seen anyone who hasn't bought a safe these days and only uses drawers to lock money. I think it's the first time his house has been stolen in so many years." He got lucky."

Although the others did not speak, they agreed with Cheng Haiyang's point of view.Indeed, there are too few and should not be used to store money in such crude and old ways nowadays.

"However, if you can know this, it means that the murderer still has a good understanding of the internal situation of the guest house!..." Jiang Ruiheng rubbed his chin to analyze.

Fang Liyuan nodded: "We have also noticed this. The murderer must have some knowledge about the staff area of ​​the guest house. But the guest house managed the corridor too loosely before, and there is a toilet diagonally across the corridor. This toilet is Externally, all residents and even passers-by can borrow the toilet. We went in and looked inside, and it is easy to see the situation in the corridor from there."

"In a word," Jiang Li said conclusively, "the safety awareness is too poor."

The others nodded approvingly.

However, it is now an afterthought, and the current top priority is to investigate the case in front of him.So Shen Yan said: "Okay, everyone has been struggling all day today, and now we can't help you with the forensic evidence. You guys should go home and have a rest. No matter whether the forensic evidence finds anything, After two days of work, everyone must be mentally prepared.”

Several people nodded in understanding: "Here, we will withdraw first."

"Ah."

Fang Liyuan and others left one after another, leaving only Shen Yan, Cheng Jinsong and Jiang Ruiheng in the office.

Seeing that there were no outsiders, Shen Yan also relaxed a little. He sat down, looked at Jiang Ruiheng and asked, "How is that Jiang Xin? Didn't cause you any trouble?"

Hearing this, Jiang Ruiheng smiled: "Not only did it not work, but it also helped a lot. It was the first problem she noticed during the autopsy."

"Really?" Shen Yan was quite surprised, and then said with a smile: "It seems that the people in 803 really have two skills! No wonder you, Ruiheng, wanted to poach the wall when you heard it."

Hearing what Shen Yan said, Jiang Ruiheng didn't know what to think of, and suddenly smiled: "But she seems to have caused some trouble for your Brother Jin..."

"Ah?" Shen Yan was taken aback, and quickly looked at Cheng Jinsong.

"Ahem..." Cheng Jinsong was drinking water, but when he heard Jiang Ruiheng's words, he choked and coughed several times.He blushed from being choked (ashamed?) and said to Jiang Ruiheng: "I said Ruiheng...cough cough...that, can you stop mentioning it?..."

Jiang Ruiheng looked at Cheng Jinsong, smiling even more schadenfreude.

Shen Yan was confused by these two people: "I said, what kind of charades are you two playing? What happened?"

When Jiang Ruiheng wanted to play tricks, even Cheng Jinsong couldn't stop him.While Cheng Jinsong was still coughing, he said slowly to Shen Yan: "Didn't I say to you before, 'Look at how Jiang Xin is doing', but someone misunderstood me, thinking that I want to be a partner, Break up the loving couple of you two..."

Shen Yan pondered for a while before he understood the meaning of Jiang Ruiheng's words, and a smile appeared on the corner of his mouth.Cheng Jinsong's old face turned even redder: "I said Ruiheng, I told you I didn't mean it that way!..."

"Do you understand that in your heart?" Jiang Ruiheng mercilessly pierced through, then got up and waved his hands, "Okay, I won't delay the show of affection between you two, I'll go first. Remember not to overcrowd Jiayu's class gone."

After finishing speaking, Jiang Ruiheng opened the door gracefully and left.

Seeing that only himself and Cheng Jinsong were left in the room, Shen Yan also completely relaxed.He leaned close to Cheng Jinsong's face and asked with a smile, "Is what Ruiheng said true?"

"Can you believe Ruiheng's words?!" Cheng Jinsong retorted loudly, but his eyes were a little erratic.

The smile on Shen Yan's face was even bigger - seeing his lover nervous and jealous for himself, this is something that everyone in love will feel happy about.Shen Yan took Cheng Jinsong's hand and smiled happily.Cheng Jinsong was tense at first, but after looking at Shen Yan a few times, he couldn't help laughing.

"Oh, my first life's fame has been ruined..." Cheng Jinsong supported his forehead.

"Don't worry, I won't tell others." Shen Yan teased and comforted.

Seeing Shen Yan's rare mischievous appearance, Cheng Jinsong's heart skipped a beat.He leaned close to Shen Yan's ear, and smiled evilly: "If you dare to say it, let's see how I will deal with you when I go back!..."

"You!..." Shen Yan's ears turned red, and he was about to fight back, but at this moment, there was a knock on the door, and Shen Hao pushed the door in, and said, "Brother Jin, everything is ready!" Did you go there?" Then he saw his brother: "Hey brother, are you back?"

"En." Shen Yan responded, and the sentence just now was completely interrupted.

Over there, Cheng Jinsong has also returned to work, he stood up: "Come on, let's go there together." Seeing that Shen Yan also got up, he then added: "I guess I have to stay here all night today, if you have nothing to do, go home early .As you said, when we finish the inspection here, no matter whether it is found or not, you will be busy in the future."

"okay."

On the side, Shen Hao also said, "Brother, I'm not going back today either."

"Okay. If you have time in the laboratory room, find a place to squat for a while, don't suffer too much." Shen Yan reminded.

"it is good."

Shen Hao responded casually, then took two steps to catch up with Cheng Jinsong, and the two left while discussing the case.Shen Yan looked at the backs of the two, a faint happiness welled up from his heart.

For the next two days, everyone focused on examining the evidence.From the bed sheets and quilts at the murder scene to the small piece of paper in the wastebasket, they are all in great detail.Hard work paid off, and on the third night, they actually had a breakthrough—in the pile of garbage in the trash can outside the guest house, the forensic team found a piece of chewing gum, and from this piece of chewing gum The DNA extracted from the inside is exactly matching the suspect's DNA extracted from Liu Dan's mouth! !

"Speaking of which, it's really thanks to the Yunxi police for keeping everything, otherwise we would definitely not be able to find this thing now." Cheng Jinsong handed the evidence bag to Shen Yan.

Shen Yan took the things, and several other members of the serious crime team came over—there was a piece of dried chewing gum in the small bag.The chewing gum is wrapped in green wrapping paper, which should be due to being thrown into the trash can. Some parts of the wrapping paper have been dyed black by something unknown, but judging from the color and pattern of the remaining part, it is very similar to A common brand of chewing gum in China.

"This is Green Arrow's chewing gum, right?" Cheng Haiyang asked to identify it.

"Really? But why do I always feel a bit different from the Green Arrow?..." Qin Kai frowned and said to himself, "Could it be that the Green Arrow changed the packaging again?..."

Cheng Jinsong and Shen Hao on the side looked at each other, showing a "as expected" smile.

Shen Yan noticed the expressions of these two people and asked, "What's wrong? Is there something wrong with this chewing gum?"

Cheng Jinsong smiled, "Qin Kai feels right, this is not Green Arrow's chewing gum at all."

? !

As soon as this remark came out, several people were shocked.Qin Kai clapped his fists and said, "Look! When I said it, I felt that something looked awkward!"

"The color scheme and pattern are different, but the biggest difference is the trademark." Shen Hao announced the answer to Qin Kai, and then said to his brother: "This is a chewing gum that imitates the Green Arrow. I found its picture on the Internet."

As he said that, he handed the phone to Shen Yan. There was a picture on the screen of the phone. There were two pieces of chewing gum side by side in the palm of a person. Their outer packaging was very similar, but upon closer inspection, there were many differences: one bottom The color is green with yellow, one is green and blue; the leaves of a small tree pattern on one side are up, and the leaves are down; the biggest difference is the English letters on the top row, one row is WRIGLEY'S, and the other is WEASLEY'S.

"Damn, they really look alike!" Qin Kai scolded with a smile, "I can hardly tell which one is real."

"You idiot!" Cheng Haiyang pointed at the screen and said, "Of course the above is true! You can't spell Green Arrow?! What the hell is that Weasley?!"

"That's Weasley, which is also an English surname." Shen Hao explained, "It's the Weasley of Ron Weasley in Harry Potter."

?

Several people were startled for a moment, and then couldn't help laughing at the same time.

"This manufacturer is quite humorous..." Fang Liyuan said with a smile.

There was also a faint smile on the corner of Shen Yan's mouth, but his thoughts had already returned to the case: "So, if we can find out where the murderer bought this chewing gum, then we may be able to find the murderer's activity area .”

"This Shen Hao has already taken care of it." Cheng Jinsong said, pointing at Shen Hao with raised eyebrows.

Several people looked at Shen Hao in surprise.Shen Hao nodded: "I found this photo on Weibo of a netizen. He said that he bought it in the canteen when he went back to his hometown for the New Year. After confirming that the evidence and the chewing gum in his photo are After the same brand, I sent him a private message and asked him where he bought it. As a result, he told me an address, "Speaking of which, Shen Hao smiled with a sense of accomplishment," he said His hometown is in Yuntang Township, Yunxi County..."

Yunxi County?Several people's eyes lit up when they heard it - there is a door!

The author has something to say:

Finally, a small theater is attached:

By the way, after Team Shen returned home, he received a WeChat message from Brother Jin——

Cheng: Shen Yan, remember to go to bed early tonight, recharge your energy, and be good.

Shen: Why?Are you so confident that you will find something tomorrow?

Cheng: No, what I mean is: When I come home tomorrow night, you won’t be able to sleep~~~<(￣︶￣)>Shen: Die! ! (╯‵ ′)╯︵┻━┻
