While Zhang Hui, Qin Yong and others were holding a case analysis meeting and an investigation report by the action team in the conference room, Lu Chuan was still busy in the field investigation laboratory.
Yang Sen and Yang Lin collected so many fingerprints that Lu Chuan needed to analyze them one by one.
There are also footprints found at the scene, which also need to be identified by Lu Chuan.
The identification of footprints is relatively simple. The footprints at the scene are relatively clear, and the traces left behind are easy to identify and analyze.
However, the results of the analysis were a little strange for Lu Chuan.
The footprints found at the crime scene were probably left by two people.
One set of footprints at the door should be the footprints left by the reporter Li Pingzhang after he opened the door and entered the church.
Because Li Pingzhang saw the body as soon as he opened the door, he did not go in deeply. The footprints were naturally only at the door.
The other set of footprints is smaller, size 37, which is in line with the characteristics of women's shoes.
The results of the identification analysis show that the person who left this series of footprints should be about 50 years old, with a height between 1.6 meters and 1.63 meters, and a weight between 50 kilograms and 55 kilograms.
In addition, some of these footprints are extremely clear, as if they were carved on the floor.
Some footprints seem to have been covered by other heavy objects and are not particularly clear.
Lu Chuan has handed over the results of the identification and analysis of these footprints to Sun Jun, and the operations team is conducting an investigation.
In the conference room.
"The investigation clues of the second operation team and the information about Song Tiezhu, the ex-husband of the deceased Zhang Cuicui, must be followed up as soon as possible."
According to Zhang Hui's report just now, from the motive, it is natural that Song Tiezhu may have committed murder.
Zhang Cuicui would send money to Song Tiezhu from the 8th to the 9th of every month, but there was no payment until the 10th of this month.
Song Tiezhu’s murder therefore makes sense logically.
Of course, on the other hand, Song Tiezhu was addicted to gambling and needed a lot of money every month to pay off his gambling debts.
Zhang Cuicui can be said to be his cash machine.
But there is a problem. Although it is difficult to ask Zhang Cuicui for money every time, once Zhang Cuicui dies, it means that the money has nothing to do with him anymore.
From this aspect, Song Tiezhu was not the beneficiary after Zhang Cuicui was killed.
“You can’t say that.”
Zhang Hui raised objections.
"Song Tiezhu and Zhang Cuicui had two children after they got married."
"Although the two divorced, the child was awarded to Zhang Cuicui."
"Legally speaking, after Zhang Cuicui's accident, her family property should be inherited by his immediate family members, that is, Zhang Cuicui's parents and him "Zhang Cuicui's two children have inheritance rights."
"It is obviously better for Song Tiezhu to ask for money from his children. It’s much easier to get money from Zhang Cui’s hands.”
Zhang Hui’s opinion...
After everyone heard this, they felt that it was indeed possible.
"Okay, according to the deployment just now, Zhang Hui, your team is responsible for fully investigating Song Tiezhu."
After Qin Yong finished speaking, he looked at Sun Jun: "The investigation of the action team How is the situation? "
"Lu Chuan has already given us the footprint identification analysis report this afternoon."
Sun Jun began to report: "Based on the information provided by Lu Chuan, we are very confident. The owner of the footprints was quickly identified and he was the cleaning staff of the Mingde Road Church.”
“This cleaner is a property worker in a community next door.”
“Because the manager of that company often goes to Mingde Road Church to listen to lectures, so he volunteered to send people to help clean the church.”
"We checked and found that the other party had been working in the community next door after cleaning on Friday." "During the time of the crime, the cleaning lady lived in the dormitory of the property company next door."

“A dozen property staff can provide proof for her that this person has an alibi.”
"So the suspicion can basically be ruled out."
"Are there any other findings?"
"The fingerprints that have been identified and analyzed by Lu Chuan are being submitted to us one after another. We have been following up on the investigation and excluding them.”
“We have checked 7 people so far”
“But there are no major findings yet.”
"How is the investigation of the surveillance videos on both sides of Mingde Road going?"
"We have completed the copying of the surveillance videos on both sides of Mingde Road this morning, and now have 7 people assigned to monitor them. Conduct analysis and investigation."
"The time of death of the deceased was around 10:30 pm the day before yesterday."
"We started to conduct analysis on all people and vehicles entering and exiting Mingde Road. Mark analysis."
"There is a community directly opposite the church on Mingde Road."
"We went door to door and conducted a survey on the residents in the community."
"What is certain is that during the day, that is, during the day yesterday, the door of the church was not opened."
"So the time when the murderer transported the body from the outside world to the church should be from after 10:30 last night to the early morning of Saturday, and from Saturday night to the early morning of this morning."
"Apparently Compared with the daytime, the flow of people and vehicles on Mingde Road is not very large at night. We have now marked people and vehicles from 10:30 on Friday to the early morning of Saturday."
"Now. We are investigating one by one.”
In fact, for Qin Yong, investigating and monitoring this clue is very important.
Since judging from the current situation, the Mingde Road Church is not the first to commit the crime, the murderer must first transport the body in from the outside world.
There will definitely be clues left.
As long as you continue to investigate carefully, you are likely to make important discoveries.
The case analysis will end soon.
However, the members of the two action teams did not rest and continued to analyze.
Lu Chuan was also busy until almost early in the morning before he finally completed the identification and analysis of all the fingerprints.
Liu Guodong is also in the laboratory.
According to the division of labor in the criminal investigation detachment, Liu Guodong, as the deputy detachment leader, is directly in charge of the current investigation office.
At this moment, five people gathered together and were discussing.
"I think this mark is relatively obvious. There should be something covering it and trampling on the footprints."
The projector in the office shows some of the footprints that Lu Chuan and others found at the church site.
Lao Bai is expressing his opinion.
“I agree with Lao Bai’s view.”
Yang Sen nodded and further explained: “Sun Jun and the others have already fed back the investigation results.”
"This footprint was left by the cleaner. The reason why it is so clear is because after the cleaner finished mopping the floor, his footprints stepped directly on it, so it is very clear."
"But these footprints are relatively different. It's rather vague."
"This is definitely not the cleaning staff who accidentally wiped the footprints with a mop."
"Because there are clear footprints on the front and back of these footprints, it is impossible. The cleaning staff only drags these one or two footprints, not the others." (End of Chapter)
