Inside the room.
Everyone got to work as Guan Feng instructed.
Guan Feng paced around, observing the details inside the room.
His smart glasses now have a zoom function, allowing him to simultaneously lock onto all the details in the room. At the same time, the trace identification is more complete than before, and he can immediately pick out the differences in the details.
A moment later.
He walked to the table.
A pink thermos was placed on the table.
This thermos was clearly a women's model, small and exquisite, but what made him frown was a dent on the rim of the thermos, which looked like it had just been bumped.
He put on his gloves, picked up the thermos, and examined the marks one by one. He then walked to the corner of the table and finally found the same dent mark there. There was a slight chip on the painted surface of the table.
Guan Feng asked, "When will the technical team arrive?"
Huang Lili immediately reported, "Captain, we'll be there soon."
As they were talking.
The sound of the elevator bell ringing came from outside the door.
Old Wang from the technical department's voice came through the air: "Is it 805?"
Guan Feng immediately walked out of the room and waved to Lao Wang.
Old Wang put on shoe covers, walked into the room, and asked, "Captain Guan, what did he say?"
Guan Feng briefly explained the case, then said to Captain Wang, "Captain Wang, the communications department is already retrieving cell phone signals. Could you collect some traces here? See if there are any signs of a struggle? By the way, I just found some traces on the table. Captain Wang, take a look, is it left recently?"
Old Wang glanced at Guan Feng in surprise, then followed him to the corner of the table.
soon.
Following Guan Feng's gesture, he noticed the bumps and scratches on the thermos, and then the marks on the corner of the table. He exclaimed in surprise, "Captain Guan, what kind of eyesight do you have?"
Guan Feng asked, "What's wrong?"
Old Wang said, "If you hadn't pointed it out, I would never have noticed. Your eyesight is amazing! Is it something you're born with?"
Guan Feng said, "Captain Wang, stop praising me. First, confirm the traces. I suspect..." He glanced at the two elderly people sitting on the sofa and lowered his voice, "There might have been a fight in the room, otherwise this room would be too tidy!"
Old Wang glanced at the room layout and couldn't help but nod, saying, "You're right! It's so tidy it's almost uninhabitable."
Guan Feng said, "Then let's investigate!"
Old Wang immediately ordered his men to inspect it.
He then took out instruments from his toolbox and, in front of Guan Feng, began to examine the thermos and the marks on the table.
A moment later.
He carefully compared the differences in the marks, and finally put down the magnifying glass. With some emotion, he looked at Guan Feng and said, "Captain Guan, I really don't know what to say to you!"
Guan Feng asked, "What do you mean?"
Old Wang said, "Judging from the marks, the collision must have happened within the last day or two, and it should also have happened around the same time the room owner left."
Guan Feng asked, "How did you figure that out?"
Old Wang said, "It's very simple! Everything leaves a trace. If you can't find it, it's just that the technology isn't advanced enough!"
"Take this thermos cup for example. The marks on it, the pink paint, are marks that most people can see when they fall on the table. But under special instruments, even the dust on these marks can be clearly seen. By comparing them with other surfaces of the table, can we determine when the dust fell in?"
Guan Feng immediately understood and gave a thumbs up, saying, "Team Leader Wang, your work really has a high level of technical skill!"
Old Wang waved his hand and said, "What technical sophistication? It's just using instruments. If we're talking about technical sophistication, your reasoning is more rigorous. Okay! We have the result now. Next, I'll prepare to conduct a full inspection of this room."
Seeing this, Guan Feng looked at Huang Lili and said, "Lili, the room needs to be thoroughly checked for any traces. Please take your uncle and aunt out first. Uncle and aunt, please go downstairs and sit for a while. This is also to help us solve the case as soon as possible!"
The two elderly people still didn't quite understand.
Huang Lili carefully explained the reasons behind it.
Both of them expressed their willingness to cooperate.
When Old Wang noticed the details on the two elderly people's hands, he suddenly said, "Let's take their fingerprints first, and then leave their footprints, in case we need to compare them later."
Huang Lili quickly began to explain.
The two elderly people obediently cooperated with the technical department's work, and were then taken downstairs to their car by Huang Lili and settled in.
The technical department, on the other hand, conducted a thorough search.
From fingerprints to footprints, from hair to fabrics...
No detail was overlooked.
Guan Feng was intently watching the technical department search for clues, and also taking the opportunity to improve his own trace evidence identification skills. At this moment, Gao Dacheng walked back, came to Guan Feng, and whispered, "Captain, the communications department has news. They've found the last cell phone signal!"
Guan Feng asked, "Where?"
Gao Dacheng said, "Tongshui River!"
......
Tongshui River.
A river that flows through the urban area of Hua'an.
According to geographical boundaries, it should be a tributary of the ancient canal.
Guan Feng, Gao Dacheng, and Qi Xia stood on the riverbank, looking at the calm flowing water, and asked with a frown, "Is this the place?"
Gao Dacheng nodded and said, "The base station can only determine the accuracy within 50 meters. The technical department, through cross-comparison of the locations of the three base stations, finally determined that it is within this range of about 10 meters horizontally and vertically!"
Guan Feng said, "This range is still quite large."
Gao Dacheng sighed and said, "This is the only way! The signal detection is coverage-based, and the technical department can't do anything better. But the good thing is that this area is all water. As long as we salvage it, we should be able to pinpoint the exact location."
Guan Feng nodded and said, "Then let the salvage team come and salvage it."
Gao Dacheng immediately contacted the salvage company.
Ten minutes later.
A professional salvage vehicle arrived at the scene.
First, the kayak was inflated and placed in the river. Then, two salvage workers put on protective suits and prepared to go into the water to retrieve the items.
Guan Feng, using the force a normal person would use to throw something, reminded them, "First retrieve what's nearby, then expand outwards."
"clear!"
The salvage team member gave a "yes" sign.
With a "gurgling" sound, the two salvage workers began to dive down and retrieve the items.
It was close to 10:30 a.m.
One of the salvage workers surfaced, holding a black cell phone in his hand.
Guan Feng looked over and saw the "O" brand logo on the phone. During the investigation, he discovered that the phone Shi Juan used before her death was from the O brand, the same brand commonly known as the "factory girl phone".
Guan Feng said, "It's very likely this one! Da Cheng, get the communicator ready and confirm the number!"
"receive!"
Gao Dacheng nodded immediately.
Guan Feng patiently waited for the salvage team to come ashore.
