Chapter 2139

"If not a student, who else can it be?" Ran Tao's eyes stared like lanterns, "can't it really be... The guard!? Am I right again? Am I really so divine? "

"God, you big head! But... The guard... "Zhao Yuzhuo said thoughtfully," I did think about this before. Well, only when the guard goes in and out of the deserted dormitory building will it not arouse suspicion! "

"Of course..." Cui Lizhu said, "the guard also has the key to the dormitory!"

"Also," Zhao Yu added, "the guard may have the keys to each dormitory. When the students go to school, he can sneak into Liu's only dormitory to see his manuscripts!

"Liu Weiyi said that he often put the manuscript on his bed

"Maybe the guard accidentally saw his manuscript and was deeply attracted..."

"There are several sunless storerooms in Zhizhen building. If he imprisons the girl there, the outside world won't know..." ran Tao echoed. "Also, the most important thing is that the guard is different from the students. He won't graduate and has to come to work every summer vacation!

"In any way, they are the most qualified!"

"I..." Cui Lizhu said, "haven't we investigated the guard before? Where is the information? "

"I have it!" After Zeng Ke answered, while searching for information, he raised an objection, "but... If it's a doorman, isn't it too obvious that the doorman led a woman into the school? If someone sees her?"

"You say," Cui Lizhu said, "will those murdered girls be kidnapped by the murderer instead of being tricked by the murderer?

"For example, what are the unimportant small doors in the school, and the guard has a key? It will not arouse anyone's suspicion to tie someone in from there? "

"Well... It's not difficult to solve this problem," ran Tao nodded. "Just ask the school and you'll know!"

"But... Why?" Wu Xiumin suddenly said, "there must be a reason for the murderer to kill. If it's a guard, why should he do such a thing?

"Moreover, if deduced from the deformity theory, I feel that if the dead are college students, it may be related to the doorman!

"Because he saw female college students every day, he was envious of them, so he started on college students!

"However, these victims are social workers, and it is still possible to do special industries," Wu Xiumin said. "I feel that the theory of guard doesn't make sense!"

"Yes..." Cui Lizhu said, "the school guards, whether they are looking at the gate or the dormitory, are usually very old people?

"Do they have this ability? Even if you have this ability, you are so old. Do you want to kill long ago? "

"This is purely your subjective imagination!" Zeng Ke said, "who said the guard must be old? When we were in college, the guards were young... "

"Nonsense, when you went to the Police University, the guards were all armed police soldiers. Of course you were young!" Cui Lizhu stuck out her tongue. "I think you're just trying to show off that you went to college!"

"..." was speechless.

"It's no use just talking, let's talk with facts!" Ran Tao opened the security information he could find and was stunned at a glance. "No? So many? "

"Yes!" Zeng Ke said, "at that time, there was no security company. All the guards were hired by the school. There were all kinds of guards, including those who were entrusted, those who occupied a position and didn't work, and those who suddenly had something at home

"So the mobility is very large and there are many locations. In the years before and after the crime, you have to say at least a hundred?"

"Silly you!" Cui Lizhu patted ran Tao, "you have a good view of the overall situation. Just look at the guard of Zhizhen building. Can you still have 100? Um... Um... "After a few glances, Cui Lizhu was depressed." what... What are these?

"Why not mark the working position of the guard? Can't see who is on duty in Zhizhen building? "

"Yes," Zeng Ke pouted, "I'm afraid the school has to find a way! It's a miracle to find these records through the account book. Don't forget, it's been more than 20 years! "

"In that case," Zhao Yu said to Zeng Ke, "then contact the school to find out the guard of Zhizhen building, and then compare it with the DNA found on the shroud!

"Doctor Zhang said that according to DNA judgment, the suspect is a man and the guard is also a man, so we can't rule out the suspect

"Moreover, the guard is familiar with the situation of Zhizhen building and school, and there are many keys. The suspicion of committing the crime is really not small! We should focus our investigation in this direction! "

"Yes!" Zeng Ke and others nodded.

Speaking of this, this temporary case analysis meeting should come to an end. Who knows, when everyone was preparing their own work, a police officer sent a report to Zhang Peipei.

"This is..." Zhang Peipei opened the report and said, "the genetic spectrum analysis of the suspect has come out. This person should be a native of Chengzhou and has a close blood relationship with the Li family of Fengjun, Zhuzhou and menxia generation. His possible surnames are 41% Li, 23% Yang, 15% Ji, 11% Wu... And 8% other surnames..."

"Wow, it's so powerful that you can even calculate your last name!" Cui Lizhu exclaimed, "fortunately, Miss Ben washed her hands in the golden basin early!"“ You don't call it a golden basin to wash your hands, "ran Tao joked." what do you call turning evil into good? "“ In that case, "Zhao Yu said to Zeng Ke," speed up and see what the last name of the guard of Zhizhen building is first? " With that, Zhao Yu opened the guard list and began to check it carefully. Unfortunately, the list was a payroll and did not show the guard's age. Therefore, Zhao Yu asked Zhang Peipei, "forensic Zhang, can we judge the age of the suspect by his DNA?"“ It's hard, "Zhang Peipei said." our existing method is to observe the repair ability of 8-OHdG, because people's DNA repair ability is gradually declining with age“ In addition, we can make a general judgment through the overall methylation level of DNA and the length of telomeres“ However, all current research methods are not suitable for our situation, because the DNA we extracted is not fresh. If we do experiments, it will produce huge errors and full of uncertainty! "“ Oh, I see! " Zhao Yu nodded, "you said so many professional terms, in fact, to tell me two words - no!" Zhang Peipei was speechless and blushed“ But it doesn't matter. At least we have decisive evidence, "Zhao Yu said." it's a big deal. Compare it with these more than 100 security guards, I don't believe I can't find the suspect!
