Normally speaking, the data in this mobile phone is not difficult to recover. If it is just soaked in water for a long time, it is actually relatively easy to recover.
However, this phone was artificially damaged before it was soaked in water. It should have been hammered by heavy objects.
So the phone was not only soaked in water, but also suffered some physical damage.
Several people in the technical team spent a lot of effort to completely extract the data.
Because the technology extracted by the Criminal Police Brigade is different from the general mobile phone data recovery on the market.
You can recover as much data as you can when recovering data outside, but as a criminal police officer, you have to recover as much data as possible.
Because these data may be used as judicial evidence, they must go all out. This is the main reason why they worked on it for more than 10 days.
"How was it?"
"90!"
The leader of the technical team is called Li Bo.
The technical team of the Criminal Police Brigade was actually established relatively recently. It was only established five years ago. At that time, Li Bo was just a graduate student majoring in computer science. It can be said that the entire technical team of the criminal police brigade was built step by step from scratch, from small to large, under his leadership.
In fact, the average age of all the technical managers in the entire Haizhou City Public Security Bureau is not very old, because the establishment time is relatively short. In addition, the computer industry is actually an industry where the age of the youth is old. Although they have rich experience, they are technically incompetent. The update and iteration will definitely be slower.
Therefore, except for some technical criminal police officers who are in leadership and management positions, generally the older ones will transfer to other places.
"The phone has some physical damage, and there is really nothing we can do about it in some places, but we have tried our best and have now restored the entire data to 90%."
Ninety percent!
This is already good.
Although Lu Chuan has never studied computer science, the skills rewarded by the system make Lu Chuan actually quite familiar with the computer science profession.
"Very good. It's good to be able to recover to 90%. I'll probably report the situation first."
Lu Chuan first affirmed the results of the other party's labor, and then wanted to hear if there were any major clues after the data was restored.
"Yes!"
Li Bo has already classified the data into categories.
"Part 1 is the call history in the mobile phone."
Although the police have found Ma Yanping's call records from the telecommunications bureau.
But what was found there was only the phone number and related call duration, but the telecommunications bureau definitely didn't know what the names of these phone numbers were in Ma Yanping's mobile phone.
In other words, the telecommunications bureau can only find relevant numbers, but not the relationship between the owners of these numbers and Ma Yanping.
However, some characteristics can be reflected through the local data in Ma Yanping's mobile phone.
"This is the address book on Ma Yanping's phone. There are 276 people in total."
"This data is complete and accurate. The data in this part of the address book is not damaged. All the data has been recovered by us."
As Li Bo spoke, he operated the computer and called up Ma Yanping's call records on October 28.
On October 28, Ma Yanping actually made two phone calls. One of them was with a female colleague who worked with him in the electronics factory. The two people said that they wanted to meet in the evening, but they did not specify where to go. Which hasn't been decided yet.
In another call, Ma Yanping made a call to a waiter at the bar, saying that she wanted to book a booth.
But obviously, it didn't happen.
"How many photos were recovered?"
Lu Chuan asked.
"About 95%."
Li Bo opened the photo according to Lu Chuan's inquiry.
"Sort these photos according to the time they were taken. I want to see some of the most recent photos before October 18th to see what he took."
"Okay!"
The technical criminal police have only restored the data. In fact, they haven't looked at what some of the data in it is.
Of course, the technical criminal police were only responsible for technology, and even if they looked at it, it would not be of much use in solving the case, so Lu Chuan screened the data one by one to see how it could help solve the case. All the photos taken and stored in the mobile phone are in chronological order, so Li Bo just sorted the order, and all the photos appeared in front of everyone at a glance.
The first few pictures are Ma Yanping's selfies.
"Stop!"
Lu Chuan said.
"When were these selfies taken?"
"Let me take a look..."
Li Bo did some manipulation: "The first two were taken on October 27th, but they were not included on October 26th. Two were taken on the 25th, and one was taken on the 24th."
Wang Zhaokai and Chen Jiang also understood why Lu Chuan asked this question.
Because of Ma Yanping’s selfie background!
The background of Ma Yanping's selfies is a tree, sometimes a wall, sometimes a house.
These scenes are familiar to everyone, but because these are some scenes in Luo Jianguo's yard, that is to say, Ma Yanping's selfies were all taken in this yard.
"Ma Yanping...lived in that courtyard!"
Wang Zhaokai concluded in a deep voice.
Lu Chuan and Chen Jiang nodded.
Indeed.
"After Ma Yanping broke up with her third boyfriend, there is a high probability that she came to rent in this rental house. In other words, she should have been with the man named Li Qiang during that time."
Li Qiang!
If Zhao Haitao did not lie, he left Luo Jianguo's courtyard in April or May, and then Li Qiang moved into the courtyard afterwards.
In other words, the person living in the courtyard with Ma Yanping is most likely Li Qiang.
"Go on!"
Li Bo continued to flip through the photos. Lu Chuan, Wang Chaohai and others went through them one by one. Except for some selfies, many of the remaining photos were slow-shaking photos.
"Stop!"
Lu Chuan suddenly shouted.
The photo of Lu Chuan calling to stop was a group photo.
It was a selfie of Ma Yanping and a man, and the background of the photo was the tree in Luo Jian’s national courtyard.
"This person...Li Qiang?"
"Now! Print out this photo and let Zhao Haitao identify whether this man is Li Qiang."
Lu Chuan made arrangements immediately.
"By the way, time! When was this photo taken?"
Li Bo checked the attributes: "September!"
"September 12th!"
The photo was quickly printed out, and Wang Zhaokai did not let anyone else go. Instead, he personally took the photo and rushed to the place where Zhao Haitao was detained.
"Do you recognize this person Zhao Haitao?"
Zhao Haitao just glanced at it and said immediately with certainty.
"Li Qiang!"
"This person is Li Qiang. I let him live in the courtyard after I left. Let me tell you, otherwise it was definitely him who did it and it has nothing to do with me. Comrade police, you must believe me. You can't What a injustice to a good man.”
