After hearing what Lu Chuan said about the suspect's height characteristics, a person suddenly popped into Song Mingguang's mind.
If we follow the clue of the forklift, the biggest suspects are Li Baowei and Zhang Bin.
Both of these two men pursued Wang Jingya, and their methods were quite extreme. They had trouble in Wang Jingya's company, and the two men even fought.
Especially Li Baowei, he and Wang Jingya have known each other for a long time. They met in high school and have been pursuing Wang Jingya for so many years.
And Song Mingguang has already investigated almost all the information about Li Baowei. The height of the other party happens to be 1.68 meters.
"How did you judge it?"
Song Mingguang quickly asked.
“Some spatial locations of the crime scene.”
Lu Chuan went on to explain: “When I went to the crime scene this afternoon, I conducted a very detailed survey of the situation there and found that I found some clues.”
“When the suspect was cooking Wang Jingya’s body, he was sitting on a small stool in front of the stove. He raised his hand next to the firewood.”
Generally speaking, if a person is sitting on a stool to burn firewood, it is more appropriate to be in the most comfortable state for his hands. So based on this, Lu Chuan can roughly judge the range of the other person's arm length.
“If the firewood is too close to the other party, it will be difficult to separate the firewood and break it. If it is too far away, the other party will have to stand up to reach it, so it is not suitable.”
Lu Chuan made a rough gesture: "From a current survey point of view, the length of an average person's arms and their height are basically in a 1:1 ratio."
"Of course, this must include the chest cavity. The width of the average person’s chest is basically the same as the length of the forearm.”
“Basically, based on the data measured at the scene, my judgment is that the murderer’s height is 1.6 meters. to 1.7 meters.”
In the process of investigating so many cases, Lu Chuan's accuracy in judging the height of criminal suspects was generally within two to three centimeters, and the difference of 10 centimeters was actually very rare.
This time, the main reason for the large gap is that the calculation data is not standard.
The suspect reached for the firewood. He may have straightened his arm, or he may have stretched his arm slightly.
It does not have a particularly clear standard, so the error has a large range.
But even though this error range is relatively large, the calculation results obtained by the bedsore show that the suspect is shorter.
You must know that as a model, Wang Jingya's height is 1.72 meters.
The suspect's height is between 1.6 meters and 1.7 meters.
"Is there any other information?"
"Fingerprints!"
Song Mingguang looked at Lu Chuan in surprise: "Holy shit! Did you find fingerprints at the scene? ”
"Didn't the Tianzhou City Criminal Investigation Detachment say that they checked the scene several times? They actually missed the fingerprints?"
If this is really the case, the Tianzhou City Criminal Investigation Detachment will not do this. It's not just as simple as being embarrassed.
Fingerprints were not collected at the scene of the crime. This can be regarded as malfeasance.
It was considered a major accident, not a mistake.
“It has nothing to do with them, this fingerprint collection is quite special.”
Lu Chuan could understand: "The suspect handled the crime scene very cleanly. There were basically no footprints or fingerprints, but the other party ignored one thing."
"He had to break branches when cooking the body. Filling the firewood into the stove, he will definitely come into contact with the firewood during the process."
"Although most of the firewood he has come into contact with has been burned, the firewood is mixed together, and it needs to be done. Separated. "
"During this process, the suspect may have encountered other firewood, but the firewood was not burned." When Lu Chuan collected fingerprint information at the meeting, he just hugged it. Have a try attitude.
On the one hand, it is very difficult to extract fingerprints from firewood.
On the other hand, it is possible that all the firewood that the suspect came into contact with was actually burned by him.
Even if Lu Chuan found the broken fingerprint now, he was not sure whether the fingerprint belonged to the suspect.
Because the firewood was taken from the firewood pile in the fire department, the firewood was originally prepared by local people.
“This fingerprint is very damaged. I looked for it all night last night, but the comparison was not successful.”
This morning, Lu Chuan had asked the Tianzhou City Administrative Detachment and several family members of the owner of the house at the crime scene to collect fingerprints.
After getting it back, he conducted a manual comparison. If it could be ruled out, then the fingerprint was likely to be that of the suspect.
"If there is a suspicious person here, collect the fingerprints and I will try it first."
"Okay!"
Song Mingguang feels confident A lot.
With the height characteristics, it is basically possible to narrow down the range of criminal suspects. Now Li Baowei's suspicion on Song Mingguang's side has greatly increased.
In addition, if the other party's fingerprints can be collected and compared, if Lu Chuan really compares, then the case will be solved.
After breakfast, they both left and went about their own business.
Song Mingguang immediately called his group over and asked about Li Baowei's situation.
“Captain Song, this guy is not good, he has an alibi.”
"Not present?"
Song Mingguang just thought that there was a breakthrough in this case and he could catch the suspect without telling him. However, his subordinates told him that Li Baowei had no proof of absence.
“Yes, on the night when the crime occurred, at around ten o’clock, Li Baowei was playing mahjong with a few workers until early in the morning. After a few of them fell asleep after drinking, several of them They have always been together."
"He has no time to commit crimes."
In this case...
Wang Jingya disappeared at 9:08 pm on the day of the incident, and her body was found the next afternoon.
According to the judgment of the forensic doctor, Wang Jingya’s death time should be in the early morning of that day.
"Are you sure?"
The subordinate nodded: "Sure, although we have not asked him to verify the situation, we have sent someone to get a closer look."
" On the night Wang Ya disappeared, there were seven of them having fun, and they could all testify, so there shouldn’t be any problem.”
In this case...
The biggest clues that Song Mingguang discovered were Li Baowei and Zhang Bin.
If the clues found by Lu Chuan are correct, then Zhang Bin's suspicion can be ruled out. This person's height is 1.85 meters, which is not at all between 1.61 meters and 7 meters as Lu Chuan said.
Although Li Baowei's height is within this range, the other party has a clear alibi.
Did you go in the wrong direction? (End of chapter)
