Although the corpse was already available, Lu Chuan couldn’t imdiately start the examination because it was in a frozen state and needed to be softened first.
Before that, Lu Chuan conducted a general inspection of the surface of the corpse.
The forensic capabilities of the Criminal Investigation Team in Tianzhou City were quite decent.
Forensic Doctor Sun Jian and Wang Changjiang from the Criminal Investigation Team in Haizhou City were old acquaintances, with similar skill levels.
They ranked above average in the entire province.
Sun Jian’s abilities were slightly higher than Wang Changjiang’s.
Therefore, Lu Chuan didn’t have major objections to Sun Jian’s autopsy report; he only needed to confirm so details.
On one hand, he was concerned about possible omissions by Sun Jian, and on the other hand, he wanted to compare it with the 116 case in Qinzhou City.
Though three years had passed since the 116 case, the follow-up and investigation of it in Qinzhou City had never stopped.
The families of the five student victims would not let the case fade away without a resolution.
Lu Chuan wanted to determine so information by comparing details between the two cases.
The surface examination of the corpse finished quickly, and Sun Jian’s autopsy report was very detailed.
While waiting for the body to soften, Lu Chuan continued to communicate with Sun Jian.
"Abrasions in the lower body?"
"This detail wasn’t specially noted at the ti."
Sun Jian’s response was within Lu Chuan’s expectations.
The marks suggested that the female victim had been violated. Without collecting related bodily fluids, this clue wasn’t particularly significant or indicative in this context.
Lu Chuan inquired about abrasions on the lower body to compare them with so findings in Qinzhou City’s 116 case.
Why hadn’t the 116 case been solved after three years?
One crucial reason was that the cri scene was exceptionally clean!
Even the top experts from the provincial forensic team found no valuable clues at the scene.
No hair, skin flakes, or footprints.
The suspect was highly cautious at that ti.
According to the case files, the suspect had climbed over the school’s periter wall.
The wall bordered the girls’ dormitory.
The perpetrator climbed from the second floor to the third floor via the security window.
There were no security windows on the third floor, allowing the suspect to enter the dormitory through the window to commit the cri.
The cri marks were very clear, but the surveillance cara near the school wall was malfunctioning.
During the cri, the suspect wore gloves throughout.
Before leaving, the perpetrator wiped off the footprints with a mop from the dormitory.
Moreover, all the cri scene investigators found were six students’ body hairs, with no trace of the suspect.
This is why the case remains unsolved to this day.
After a while, the body softening was complete, and Lu Chuan focused on examining the lower body marks.
"There are abrasions around and above."
Lu Chuan’s suspicion was confird, as there were indeed abrasions around the female victim’s lower body.
"This..."
"Generally, such abrasive injuries occur only if the suspect’s body hair is shaved."
This explains why the Criminal Investigation Team in Tianzhou City found no body hair of the suspect.
Because it was shaved off by the perpetrator.
After confirming this, Lu Chuan left the autopsy room and proceeded to the special eting room of the serious cri unit.
Song Mingguang and Wang Song had already started working separately, only Li Donglin remained.
"Director Li, I’d like to go to Qinzhou."
Qinzhou?
"You want to visit the site of the 116 case?"
Lu Chuan nodded: "I have so theories, but I need to verify them on-site."
"Also, can we et with the surviving witnesses?"
Li Donglin had planned for Lu Chuan to go to Qinzhou, but hadn’t expected it to be so soon.
As Lu Chuan started investigating the 116 case in Qinzhou, other teams were also making progress.
The first feedback ca from Song Mingguang’s investigation of bank card information.
As Li Donglin anticipated, the victim had more than just three bank cards.
"Under the victim’s na, there were a total of 5 bank cards, three of which we found at the victim’s ho."
"The three bank cards we found included salary cards of an adult male and female victim, and one mortgage card."
"The other two bank cards contained fixed amounts, 30,000 and 40,000 respectively."
"On the day of the cri and the following day, soone withdrew money from the bank cards at an ATM."
The information brought back by Song Mingguang was crucial.
Based on the current situation, the bank cards must have been taken by the perpetrator.
Li Donglin had already deduced that the perpetrator, being cautious from previous cris, likely withdrew the money from an ATM rather than going to a bank.
ATM withdrawals would inevitably leave video surveillance evidence.
"Where’s the surveillance?"
"It’s being retrieved, I’ll report to you as soon as it’s available!"
After hanging up with Song Mingguang, Li Donglin hadn’t even had the chance to catch his breath.
Wang Song also called in.
"Director Li, we’ve found so clues in a supermarket’s surveillance."
It proved that the serious cri unit’s investigation abilities were indeed impressive.
Less than a day after Wang Song set out, he found a vital clue.
Half an hour later, all available investigators gathered in the conference room.
Wang Song played a one-minute surveillance video.
"Based on the body type analysis from Lu Chuan’s footprint identification, we screened videos from a supermarket and a dental clinic on either side of the residential area."
The entrance of the victims’ residential complex didn’t have any surveillance, but there was a supermarket and a dental clinic on either side.
The supermarket and dental clinic had their own surveillance equipnt that captured street information outside their establishnts.
Theoretically, anyone entering the residential complex’s main entrance had to pass by the supermarket or dental clinic.
Unless the suspect ca directly from the front of the residential entrance, bypassing the supermarket and dental clinic’s surveillance.
However, the traffic was heavy in front of the community entrance, and there was a one-ter-high fence. Three people crossing the road would attract a lot of attention.
Chances are the suspect wouldn’t choose this thod.
Furthermore, the suspect likely didn’t know about the surveillance in the supermarket and dental clinic, which covered the street outside.
Therefore, probabilistically, the suspect should have left traces in these two surveillance systems.
"Look at this person!"
The person appearing in the surveillance was a slightly overweight middle-aged man.
"Around the ti of the cri, about 500 people were screened in the surveillance video."
Of course, this so-called screening wasn’t done by Wang Song alone.
Before Wang Song’s arrival, the Criminal Investigation Team in Tianzhou City had already identified these two surveillance caras, using the information they provided as key clues to investigate everyone.
