The key retrieved from Zhang Qiuzhen was identified by technicians and was believed to be a key to a drawer lock. The security level of the lock core is level A. It can basically be identified as a key to an ordinary drawer or cupboard door. As for the number on the key
, no clues have been found yet.
After two more days of squatting in Shangdong, Dr. Qiao and Zhang Pengfei found no trace of the murderer of Zhu Jun and Zhu Dongxiao. They had returned to Shangdong. At this time, they were gathering in He Xiaohui's office to analyze the case.
"There is no way. We have checked all the videos around Futai Community and have never found any suspicious characters. It seems that the murderer in this case is very experienced and has strong counter-detection capabilities." Dr. Qiao sat on the sofa with his legs crossed.
explain.
"Captain Zhang and the others were very cooperative with the case. They stayed up with us for several days and nights, which made them very tired." Zhang Pengfei sat next to Dr. Qiao, looking exhausted.
"Thank you for your hard work, you two. If you have nothing to do soon, go back and have a rest." He Xiaohui said.
"It's not entirely true to say that we didn't gain anything this time. In the video of a camera far away from Futai Community, we found a more interesting picture." Dr. Qiao took out his mobile phone and pulled up a photo.
He went to the coffee table and continued:
"Look at this guy."
Su Le stretched out his head to look, and saw the back of a man in the photo on his phone. The man was wearing a hat and a long windbreaker, and the skirt of the windbreaker was blown up by the wind.
"Are you dressing up like this in summer to look cool?" He Xiaohui took a look and said.
"Look at his clothes that are blown by the wind," Dr. Qiao reminded.
"You mean his buttons?" Su Le asked.
"Yes, does it look familiar?"
"This button looks very similar to the button we found on the river viewing platform. Unfortunately, the video is not clear enough to determine that it is a kind of button."
"There is one more detail. If you look carefully, I discovered it by accident after looking at it for a long time." Dr. Qiao had a disloyal expression on his face.
"One more detail?" Su Le picked up the phone and enlarged the photo to observe it carefully.
"Ah, it seems like the bottom button of this windbreaker has fallen off." Su Le said loudly.
"Really?" He Xiaohui asked.
"Yes, according to the conventions of clothing design, there should be a button underneath, but it's missing now."
"Did it get lost on the river viewing platform?"
"Now we can only speculate. If this piece of clothing can be found and the buttons are made of the same material and style, it can be used as evidence."
"Did you follow up on this man's whereabouts later?"
"We looked for it, but couldn't find it. This man just flashed in front of the camera. We later expanded the search scope and found no trace of this man again," Zhang Pengfei said regretfully.
"Looking at it this way, the murderer of Meng Yuanming and the murderer of Zhu Jun may be the same person." Su Le said.
"Currently we can only say that it is possible," He Xiaohui said.
"Although this clue cannot allow us to pursue it, it provides us with an idea. The two cases were carried out by the same group of people, and for the same purpose." Dr. Qiao said.
"This also indirectly proves that the information Tian Shan provided us is accurate. She said that Meng Yuanming met with a lawyer, so the lawyer must be Gao Yongfeng. But what we still don't know is: What documents did Meng Yuanming reject?
What other documents were signed? Why was Gao Yongfeng killed?" Su Le analyzed.
"Maybe the key we found can provide us with the answer. Let's all take a look at this key and see if we can find any clues." He Xiaohui put the key found from Zhang Qiuzhen in front of everyone.
"Is this an ordinary key? I just don't know what the number means." Dr. Qiao picked up the key and looked at it.
"Why do you think Gao Yongfeng left this key at Zhang Qiuzhen's house who has not returned for more than ten years?" He Xiaohui walked around the office and continued:
"And he also left a briefcase there and said he would give it to anyone if they asked."
"He also said that if the police come, he will give the key to the police." Su Le added.
"Then if you didn't go to Zhang Qiuzhen's house to investigate Gao Yongfeng's affairs, this key would never have appeared?" Zhang Pengfei asked puzzledly.
"According to Zhang Qiuzhen's description, you can think so. And Zhang Qiuzhen doesn't care about the key at all." Su Le replied.
"We need to carefully sort out the timing of this matter and see if we can get any inspiration." He Xiaohui said:
"According to the information provided by Gao Yongfeng's mobile phone signal positioning, the time he met Meng Yuanming should be June 8. Meng Yuanming was killed on June 15, the media exposed Jiang Zhong's body on June 19, and Gao Yongfeng went home to deliver the keys on June 20.
Gao Yongfeng had a car accident on June 24."
"Based on what Tian Shan said about the two documents, we can speculate that Gao Yongfeng asked Meng Yuanming to sign a document on the 8th, but Meng did not sign and instead signed another document. Because Meng did not sign the document, he was killed on the 15th.
After the media exposure on the 19th, Gao Yongfeng felt in danger, so he sent the documents to his home on the 20th, and then he had a car accident on the 24th," Su Le said.
"It sounds reasonable, but some details cannot be connected. How did Gao Yongfeng know that Meng was killed? The media exposure only said that the body was found in the river, and did not report that the body was Meng Yuanming. And at that time, we had not even confirmed the body.
identity." Zhang Pengfei said.
"Okay, let's talk about the key first. How did Gao Yongfeng know that the police would go to Zhang Qiuzhen to find out the situation?" Su Le said.
"And that bag. Gao Yongfeng also knew that someone would look for it," He Xiaohui said.
"I think this Gao Yongfeng is not simple. He may have had a premonition that something would happen to him, so he deliberately left the bag with An Yong's people and the keys with the police." Dr. Qiao said.
"You mean Bao is just a temporary measure to make An Yong's people think they have found what they need?" Su Le asked.
"It can be understood this way."
"Doesn't that mean this key is more important than the bag?"
"This is obvious. Leaving the key to the police is in the hope that the police will use the key to find evidence and reveal the truth." Zhang Pengfei said.
"But which lock should this key open?" He Xiaohui said.
"Since Gao Yongfeng left the key to the police without any hint, it means that Gao Yongfeng believed that the police would be able to find the lock." Dr. Qiao said.
"Isn't he afraid that Zhang Qiuzhen will get the key to unlock the door?" He Xiaohui asked.
"He must think Zhang Qiuzhen can't find the lock."
"Where is the lock that Zhang Qiuzhen can't find but the police can find?"
"First of all, it can be ruled out that this lock is inside Anyong Company. If it is inside Anyong Company, there is nothing that they can't open. It is also impossible for it to be in the home of Zhang Qiuzhen or his three mistresses. Excluding these private places, the remaining
The only places we can get off are lockers in shopping malls and train stations," Su Le said.
"Anyone can open these places as long as they get the key," Zhang Pengfei said.
"But if you don't know which cabinet it is, you can't open it randomly." Dr. Qiao retorted.
"The key has a number. It may be difficult for ordinary people to check it, but it is easy for us police to check it," Su Le explained.
"Yes, that may be what Gao Yongfeng meant. He deliberately left only the key but not the location and voucher, just to hope that the police would use their investigative power to open the cabinet." Dr. Qiao said.
"Then let's investigate where to provide such lockers?" Zhang Pengfei said.
"Nowadays, shopping malls and train stations all provide lockers with electronic locks. Where can these lockers with keys be used?" He Xiaohui said.
"Yes, where can I find such a locker that can be opened with a key?" Zhang Pengfei scratched his head and thought for a while and said:
"Yes, bathhouses or bathing centers have cabinets with keys like this."
"The locks in that place are very small, but this key is relatively large. It should not be a place like this." Dr. Qiao said.
"Oh! I remembered." Su Le suddenly shouted loudly.
Everyone turned their heads to Su Le. After looking at everyone for a while, Su Le said slowly:
"bank!"
"Yes! Bank! The safes rented by banks have this kind of key. The bank's safe has a double interlock. When opening it, you need to provide identification to take out another key from the bank and open the safe together with this key.
” Dr. Qiao explained.
"Ordinary people or organizations cannot ask the bank to produce another key without proof of identity," Su Le said.
"So Gao Yongfeng casually threw the key in the drawer and asked Zhang Qiuzhen to give the key to the police." Zhang Pengfei suddenly realized.
"Okay, since everyone thinks it is a bank safe, let's quickly investigate how many banks in this city provide safe rental services." He Xiaohui ordered.
"Yes!" Everyone agreed and quickly started investigating.
Many things can be done with twice the result with half the effort as long as they find the right direction and take action. Su Le and the others first called the bank to see if they provide safe deposit box rental services. If so, they would send a photo of the key to them for identification. They even went to the bank to identify it.
I didn't even go there, but I found the home of the key - Zhongjiang Bank in less than half a day.
After Su Le and Zhang Pengfei completed the relevant procedures, they drove to Zhongjiang Bank.
"Su Le, what kind of person do you think Gao Yongfeng is?"
"I can't figure it out. This question has been bothering me for several days. I really can't understand that my father, who is a policeman, has such a lifestyle friend."
"Maybe opening this safe will solve the mystery."
"hope so."
With the necessary procedures and the guidance of bank personnel, the safe opening process was very smooth.
There is only one document bag in the safe. There is a USB flash drive, a bank card, a photo and three A4 papers in the document bag. One of the three A4 papers is Meng Yuanming's statement, and the other is what Gao Yongfeng gave to his wife.
Letter, one is a letter from Gao Yongfeng to his son.
Su Le was shocked when he saw the yellowed photo. In the photo, three young people stood in a row with their arms around each other's shoulders, with joyful smiles on their faces. The man standing among the three was Su Le's father.
Su Zhengyang, the person on the left side of the photo is obviously the young Gao Yongfeng, and the person on the right side of the photo is Su Le, whom he has never seen before.
