Two days later, at the Shanghai Police Station, in the temporary office of the Special Investigation Group.
"Why are the test results so slow?" Cui Lizhu, who was standing in front of the whiteboard, looked a little anxious. "I remember that Dr. Zhang used to be very efficient."
"Don't worry!" Zeng Ke frowned and said, "The samples were just sent last night. Zhang Peipei didn't sleep last night!
Don't forget that we are using the blood of the suspected victim's relatives, which is much more troublesome than ordinary genetic comparisons … "
"Don't worry," Ran Tao said. "I just went over to take a look. Dr. Zhang said that the results will be out in ten minutes. Come on, let's continue talking about the case!"
"What's the point of talking about the case without the results?" Cui Lizhu glared at Ran Tao. "If the arm in the safe is not Sun Yujiao's, what's the point of talking about the case a hundred times?"
"I think …" Zeng Ke said, holding a piece of information in his hand. "The possibility is very high! We have already asked Sun Yujiao and Gao Chaolin's relatives. Didn't they confirm that Sun Yujiao really has a Saint Norsk 1918? "
"No way!" Cui Lizhu waved her hand. "Although the Saint Norsk 1918 is rare, there is more than one. There are all kinds of people in Shanghai, so it's not surprising that they have the same watch!"
Ran Tao put his hands on his hips and said, "I've said it before. I should take that watch to the owner of the watch shop to identify it and see if it's the one he repaired!"
"No need." Cui Lizhu shook her head. "As long as the results are out, everything will be clear!"
"The point is …" Wu Xiumin, who had been silent all this time, finally spoke. She was also holding a piece of information in her hand. "In this file about the fire in villa No. 19, there was no mention of anyone missing an arm!"
"Xiumin," Zeng Ke retorted. "After all, that was a case record from 30 years ago. At that time, the examination technology was not as advanced as it is now. If they had suspected from the beginning that it was an accident, then the autopsy would not have been particularly detailed!
"It's normal for there to be omissions!"
"Yes," Ran Tao said. "Finally, the police investigation did not find any obvious suspicious points, did they? The investigation concluded that it was an electrical fire, and there was no trace of arson! "
"Now that you mention it, it reminds me of something," Cui Lizhu said. "There seems to be something wrong with the circuit fire! You have to know that this is a mansion in Shanghai. How could the circuit catch fire so easily? "
"That's hard to say …" Zeng Ke said. "There are many kinds of electrical fires. It depends on the cause of the fire …"
Just as Zeng Ke said this, the office door was suddenly pushed open. Team leader Zhao Yu suddenly appeared in front of everyone.
"Everyone, I'm back!" Zhao Yu said, holding a report in his hand. "I came at the right time! Just in time, just in time! "
"…" Cui Lizhu covered her face. She didn't seem to care about Zhao Yu's arrival.
"Boss, you're back? You're fast! " Ran Tao's face was full of excitement. He quickly looked behind Zhao Yu and asked, "What did you bring us this time?"
"Isn't that it?" Zhao Yu opened the report and said loudly, "Through comparison, it has been confirmed that the owner of the arm is a blood relative of the comparison.
According to the relationship chart, there is an 85% chance that the owner of the arm is Sun Yujiao! "
"You …" Cui Lizhu's eyes widened. She was just about to ask where Zhao Yu had gotten the report from, but the next second, Zhang Peipei appeared in the office.
There was no doubt that Zhao Yu had gotten the report from Zhang Peipei.
"That's great!" Zeng Ke said excitedly. "In this way, we have made significant progress in the case. We finally know who the owner of the arm is!"
Ran Tao then said, "But … It's quite strange! Since the person was burned to death, what happened to the arm?
"Is the fire not an accident?" Ran Tao guessed. "Someone committed the crime first, then set the fire? Because they couldn't take off Sun Yujiao's watch, they cut off his arm? "
"It was definitely not for money," Wu Xiumin said. "If it was really a robbery, murder, or arson, then the watch would have been sold a long time ago!"
"It's not easy to sell the watch!" Ran Tao insisted. "Such an expensive watch would have been exposed as soon as it was sold!"
"Are you out of your mind?" Wu Xiumin scolded him. "Even if they didn't intend to sell it, putting the watch in the safe could explain it. But why put half of the arm in the safe?"
"Oh …" Ran Tao scratched his head out of habit. "That's true …"
"It seems that …" Zeng Ke murmured. "This case is not easy to solve. Thirty years ago, there was no DNA technology, and the fire was judged to be an accident, so there were no samples left!
"In other words, the person who died in the fire might not even have been Sun Yujiao! Maybe the arm was chopped off later … "
Zeng Ke's words sent a chill down everyone's spine. They couldn't imagine what would have happened if it hadn't been Sun Yujiao who had been burned to death.
"That's true …" Zhao Yu scratched his head with Ran Tao, but his eyes were full of excitement. "If that's the case, then the level of the Arm in the Safe Case will have to be upgraded!
There may be something fishy about the fire 30 years ago! "
"Boss …" Ran Tao swallowed hard. "We won't have to open the coffin like we did in the past, right? Medical examiner Zhang, "he asked Zhang Peipei," Can you still get DNA from the bones that were burnt by the fire? "
"Well …" Zhang Peipei said. "It depends on the situation! But, generally speaking, as long as the burn is not too serious, it can still be tested! "
"So …" Zhao Yu asked, "Does Sun Yujiao's family have any immediate relatives? Who did you find to compare the DNA with? "
"It's Sun Yujiao's uncle," Wu Xiumin replied. "This is the only closest blood relation we can find so far!
"As for the male owner, Gao Chaolin, we are still looking for him," Wu Xiumin said. "Because Gao Chaolin is from Tongjiang, it will take some time to find his close relatives!"
"Well, then …" Zhao Yu looked around at everyone and asked, "Next, who can tell me who this couple is?"
"Hey, boss …" Cui Lizhu quickly grabbed Zhao Yu's arm and asked, "What do you mean by that? Have you completely returned? Are you going to leave or not? "
"Um …" Zhao Yu thought for a moment, then said, "I won't leave for the time being! What's wrong? "
"What a pity!" Cui Lizhu pouted. "I thought we would be able to solve a beautiful case when you weren't around!
"Now that you've returned, all the credit belongs to you again!"
"Nonsense!" Zhao Yu laughed. "Even if I didn't come back, the credit for solving the case would still be mine. After all, I, the great detective Zhao, am famous now!"
Cui Lizhu looked at him with contempt.
"Okay!" Zhao Yu patted Cui on the shoulder and smiled. "You'd better cheer up!
"Can't you see? The safe case may involve one or more major murder cases. The criminal has been at large for more than 30 years. We can't let him go easily! "
