After speaking, Sun Biao looked at Wang Zhaokai.
“Before our meeting, Zhao Kai and I checked each other’s information to confirm Hu Huihui’s identity. Then, based on the other party’s situation, we probably made a preliminary judgment on the nature of the case.”
Sun Biao switched the projection, and there were just a few text messages on it.
“First, Hu Huihui went to the south to purchase goods before she disappeared. At that time, she should have used cash. After buying a large amount of clothing, Hu Huihui should not have much money with her.”
“ Therefore, it is initially judged that the possibility of the other party killing someone for money does not seem to be high.”
"Second, everyone, look at this photo of Hu Huihui."
On the projection, there is a stylishly dressed girl with a tall figure and a sweet smile.
“This is an artistic photo taken by Hu Huihui at home when she disappeared 10 years ago.”
“Although Hu Huihui dropped out of high school, she is very shrewd. They are quite famous in several villages near the village. They can make money and are beautiful. They are famous in the village."
"Back then, many people in the village went to Hu's house to propose marriage. .”
"In addition, when the Marine Corps inspected the scene, they found that the deceased was not wearing clothes when he was buried in the roadbed."
"So, I personally think that the other party was probably killed after being strengthened. "The greatest sex."
Sun Biao turned on the projection and continued his analysis: "According to what Captain Wang just said, Hu Huihui usually takes a taxi back home from the train station after returning from the south."
"So, I think this time will be no exception."
"So, is it possible that the taxi driver took advantage of the situation?"
"In addition, another thing is that I discovered that during this road construction, because the entire National Highway 121 was dug, the road into Beihong Village was cut off."
Sun Biao drew a picture on the whiteboard Simple diagram.
“I asked the construction company. If this was the case when the road was built, then the road in and out of Beihong Village at that time should be said to have been cut off.”
“So If the taxi driver had not attacked Hu Huihui at that time, the location where he got off the bus was not in Beihong Village, but near National Highway 121. "Then, is it possible that he was a construction worker at that time? He took advantage of the situation, killed the opponent after invading him, and then buried him under the roadbed? "
These two possibilities...
Everyone nodded after hearing this, quite agreeing with it.
Lu Chuan was also listening carefully to Sun Biao's analysis.
Lu Chuan's strength is to obtain clues from the analysis of clues at the scene.
But when it comes to case reasoning or experience, compared to Sun Biao, Chen Jiang, Wang Zhaokai and others, Lu Chuan, to be honest, I think he still has some gaps.
Sun Biao's two analyzes were based on reasonable assumptions based on the situation at the time.
For example, in the second hypothesis, construction workers committed the crime.
Because normally, the taxi driver would take Hu Huihui directly from the train station to Beihong Village. There would be no special circumstances in between and he would not stop.
Even if the car is parked, Hu Huihui will not stop taking a taxi for no reason.
So the possibility of encountering construction workers near National Highway 121 and causing them to commit crimes is actually not high.
But if the road in and out of Beihong Village is cut off due to the construction of National Highway 121, then the taxi driver will not be able to cross National Highway 121 and enter Beihong Village.
So it is possible that Hu Huihui will get off the car on the other side of National Highway 121 and interact with the construction workers.
Of course, whether the circumstances of the crime that year were the same as what Sun Biao and the others had guessed was just a theoretical analysis and speculation.
"Team Lu, I don't have any more here."
Sun Biao returned to his seat, and Lu Chuan looked at the others.
"Do you have any other suggestions?" Several people looked at each other. The suggestions from the squadron leaders were not all personal suggestions. Before the case analysis meeting, they had already communicated and summarized information with each other and among the squadrons.
So, after the squadron leaders finished speaking, no one had any other opinions.
Seeing that no one had any objections, Lu Chuan sat up straight.
“Okay, let me talk about the current situation here.”
Lu Chuan used a projector pen to switch slides: "Let's first talk about the identification and analysis of the deceased's skeleton."
"Judging from the skeleton, the cause of death of the deceased should be suffocation, and the fracture of the hyoid bone is very obvious."
On the projection is an overhead photo of the skeleton, and a close-up photo of the hyoid bone on the side.
"In addition, there are no signs of injury to other skeletal parts of the deceased, except for the fracture injuries caused by the excavator."
This shows that the deceased should not have been violently injured before his death, causing bone injuries.
What Lu Chuan wanted to talk about was not that, but the shovel found in the pit.
“The shovel found in the pit was probably the tool used by the murderer to dig the pit and bury the body.”
“I found a third of the shovel on the soil wrapped above. Fingerprints!”
Fingerprints?
Everyone was shocked.
Then look at the photos on the projection.
The photo is an enlarged photo, which can clearly show the fingerprint rubbing marks inside the soil.
Lu Chuan continued: "Although these one-third fingerprints are not particularly clear and rough, they are almost the same for identification."
"Unfortunately, this afternoon I After the identification and analysis of the fingerprints, the target fingerprint was not found in the fingerprint database.”
Everyone felt a little pity after hearing this.
If there had been, the case would probably have been solved.
But it doesn’t matter if you don’t have it.
With these one-third fingerprints, even if the murderer has not been identified now, as long as the suspect has a suspicion scope, he can be identified by collecting fingerprints.
"I just listened to everyone's analysis, especially Captain Sun Biao's inference about the nature and scope of the suspects. I personally agree."
Lu Chuan said Here, get up and walk to the projection.
It was that shovel.
“However, the appearance of this shovel, I think, on the one hand, it can broaden the scope of criminal suspects, and on the other hand, it may also be able to narrow down the scope of criminal suspects to a greater extent.”
When Lu Chuan was just listening to Sun Biao's analysis, he was thinking about the shovel.
"According to the investigation results from Zhao Kai, it can be determined that the time when Hu Huihui disappeared should be around noon that day."
Lu Chuan wrote the time on the security board: "We assume that if it was If the taxi driver committed the crime, the driving time from the train station to Beihong Village would be about 50 minutes.”
"That is to say, if the other party immediately dumped the body after committing the crime at this time, the time would be during the day."
"In broad daylight, a taxi driver took a shovel and dug at the road construction site."
“How likely is this, do you think?”
“And, would a taxi driver carry a shovel with him?” (End of Chapter)
