Roland¡¯s confession has almost no value in solving the case. The criminal police team has begun a comprehensive investigation of the deceased¡¯s social relations non-stop. The coal boss Chen Tao has also been labeled as a key investigation by Ye Qian.
After a short rest, in the afternoon of the same day, we began to conduct a comprehensive investigation of the surrounding scene and garage. According to the investigation rules from far to near, our first step was to find the suspect's squatting area.
The crime scene is located at the southernmost end of the community. The villa is along the street on three sides, and there is a lush forest directly south of the backyard. According to normal thinking, if the suspect had squatted beforehand, the woods behind the house would definitely be the best choice. .
Fortunately, the ground in the woods is soft soil, and due to regular irrigation, it is easy to leave clear shoe prints in the woods. In addition, in order to ensure the original ecology of the woods, the property management of the community uses fully automated irrigation methods, so generally no one will enter.
The visual distance between the woods and the villa is only about 20 meters. As soon as we walked to the edge of the woods, we made a major discovery.
¡°This way, this way, and this way, they are all the suspect¡¯s shoe prints.¡±
After saying that, I continued walking deeper into the woods along the direction of the shoe prints: "The shoe prints here are relatively old, but they are relatively fresh here. Brother Ming, the suspect has stepped here more than once!" I quickly concluded. this important conclusion.
Brother Ming stood at the position of my finger and looked towards the backyard of the crime scene: "As long as the lights are on in the villa, you can almost see the entire living room and bedroom from here."
"The scene is very clean. The suspect did not leave anything that could be used to extract biological materials." Lao Xian searched carefully and said disappointedly.
"The suspect has been here more than once. Is he really waiting for Ruan Yulin?" Brother Ming held his chin and paced back and forth.
There are some places at the scene that are really difficult to explain. If the suspect¡¯s motive was to kill, why did he loot all the belongings in the room? If the suspect was embezzling money, why did he visit the spot many times and show such obvious venting of anger at the scene?
The two main motives for committing crimes, property theft and murder, are like weights at both ends of the scale. As the investigation deepens, the weights are constantly alternating up and down. Someone has to ask, is it possible that the suspect wants to kill people and embezzle money at the same time? Of course it is possible, but solving a case is not just random guessing. All conclusions need to be supported by evidence.
"Let's go to the garage and have a look." Since I can't figure it out, I can only put it aside for the time being. As a technician, I must have the psychological quality to maintain a normal mind at all times. Otherwise, a slight piece of evidence may lead to errors in judgment. As a leader, Brother Ming, who is a technician, has much stronger psychological adjustment ability than ordinary technicians.
Although the garage is on the basement level of the villa, the entrance is in the yard on the west side.
The access control of the garage is a folding rolling shutter door. After the incident, the rolling shutter door has been closed, which also preserved the original appearance of the scene at the time of the incident. With the help of the property management company, we opened the door to the basement level. In order not to damage the traces of the scene as much as possible, this time I, Pang Lei and A Le entered first, while the others waited outside the door.
There is a winding cement road for cars to drive in and out. In order to increase the friction of the ground, many linear protrusions were drawn on the cement road. This design is convenient for travel, but it makes observing tire marks difficult. Big trouble.
?Going all the way down the cement road, at the end is a garage with 6 parking spaces. At this time, three luxury cars are parked neatly in the parking spaces.
"Mercedes-Benz S600, BMW Mini, Audi A8, why are they all here?"
"What's your expression?" Pang Lei put down the camera and asked.
I took out my phone, clicked on the photo album, pulled out three pictures and explained: "These are the three cars under Ruan Yulin's name that I found in the system. Look."
Fat Lei looked and checked: "Grandma, three cars are here. Did the suspect drive himself to commit the crime?"
"Look here!" Ah Le squatted in the corner of the garage and pointed at a bag of chocolate wafer packaging that had been squeezed and deformed. "There are shoe prints on it."
Fat Lei and I looked at each other and walked over in a few steps: "Yes, these are the suspect's shoe prints. He has been in the garage."
¡°Xiaolong, look, there are also chocolate marks on the ground here.¡±
Following Fat Lei¡¯s fingertips, a string of clear dark brown spots stretched all the way to the vicinity of the Mercedes-Benz S600.
"Let's go over and have a look."
"Little Dragon!" Ah Le can always find the key to the problem in the shortest possible time.
I followed the path of his fingersLooking in the opposite direction, through the windshield of the car window, I soon made a major discovery: "Isn't this the Bluetooth card access control base that is sucked on the car window? The Bluetooth card has been broken off?"
"If the suspect had not fled the scene by car, he would not have broken off the Bluetooth card of the car in one fell swoop. Obviously, there was a car parked in the parking space where we were just now, and this car has been stolen." Le analyzed.
¡°It¡¯s easier to handle if you have a targeted target.¡± I snapped my fingers and opened the tool box marked ¡°Electrostatic Adsorption Instrument¡±.
The garage has a frosted cement floor, which has high dust coverage and low contrast. It is difficult to detect shoe prints and tire marks with the naked eye. The best way is to use electrostatic adsorption. We all know that once someone steps on the dusty ground, the dust will be taken away along with the shoe prints due to the squeezing of gravity. The principle of electrostatic adsorption is to adsorb all the dust at the crime scene on a very contrasting sheet. black electrostatic paper so that all traces in the room can be seen at a glance.
The results of the adsorption were gratifying. The suspect indeed drove a car and fled the scene. Judging from the width of the tire tracks and the depth of the tire tread, the stolen vehicle should be an off-road vehicle with strong climbing capabilities.
The suspect did not choose among the three cars in the garage, but chose an off-road vehicle. Our inference is that the off-road vehicle has a larger capacity than ordinary cars, making it easier to hold a large amount of stolen property. This also confirms our view from the side. Conclusions of the site investigation.
Next, this off-road vehicle that was not in the name of the deceased Ruan Yulin became the focus of the investigation. The suspect drove a car that carried a large amount of stolen items. It is impossible for him to abandon the car and flee at will. If we can figure out the vehicle brand, specific characteristics such as color, then subsequent investigation work will become simpler.
The conclusion of the re-investigation was fed back to Ye Qian as soon as possible, and all that was left was to patiently wait for the investigation results from the criminal police team. (Remember the website address: www.hlnovel.com
