Rooftop.
According to Xu Mo, this should be the primary crime scene.
Moreover, the killer and the victim must have known each other. Otherwise, the victim certainly wouldn't have left their back unguarded to a stranger while standing at the edge of the rooftop... Too dangerous.
Han Fei brought several officers up and immediately began collecting biological traces left on the rooftop.
However, the results were not very satisfactory.
In a purely outdoor environment, biological traces are difficult to preserve.
Before their arrival, most of the biological traces here had already been washed away by wind and rain.
"Captain Han, we couldn't find anything. The wind is too strong up here, hair and fibers can't be retained, and there's still a light drizzle falling, so fingerprints have been washed away too."
After searching for about twenty minutes, the officers hadn't discovered any useful clues.
Seeing that not a single useful piece of evidence had been collected, Han Fei sighed.
"Let's pack up and start investigating through surveillance footage and the victim's personal relationships."
Although they hadn't found any valuable clues,
It wasn't as if they had no options left.
Investigating through surveillance footage and the victim's personal relationships should still yield some results.
After all, one thing that's been confirmed now is that the killer and the victim must have known each other!
Back at the police station, Han Fei reviewed the surveillance footage from inside the building again.
The result showed that in the footage, the victim went up to the rooftop alone, and neither before nor after he went up did anyone else go there, right up until the body was discovered.
This case was getting difficult; it seemed it wouldn't be solved quickly...
Considering it was already late, Han Fei decided not to call all the officers back to work on the case, but instead let them rest well tonight and start investigating early tomorrow morning.
The next day.
Because of the case, the officers arrived at the police station early, before their official start time.
As soon as everyone arrived, Han Fei gathered them all together and briefed them on the information he had learned last night.
However, just then, an emergency call came in.
Just moments ago, another body had been discovered, and like last night's victim, this one had also apparently committed suicide by jumping from a building.
The operator immediately reported this information.
"Another suicide? Also by jumping off a building?" Han Fei's expression grew serious upon hearing this news. "What was the reason for this suicide? Also a stock market failure?"
The operator shook his head.
"This victim didn't die because of stock market losses. They say it was due to relationship troubles. The victim was only eighteen, a freshman at the University of Technology."
They hadn't even figured out last night's case yet, and now another one had come in.
Han Fei's instincts told him that the victim in this newly reported case might not have committed suicide either... and there was a high possibility that the deaths of the two victims were connected.
But this was just Han Fei's speculation. To know the specific situation, they'd have to go to the scene and take a look.
Thinking this, Han Fei temporarily set aside what he was doing and took a portion of his team straight to the scene.
...
At the school.
Before the police arrived, the school had already promptly evacuated the students and cordoned off the scene, not wanting to frighten more students or expand the impact.
When Han Fei and his team arrived at the school, a school leader who had been waiting for them immediately led them to the scene.
"When was the body discovered?" Han Fei asked, looking at the body on the ground after they arrived.
The school leader who had led them there recalled.
"About half an hour ago. This student probably jumped from the top floor of the dormitory. The body was discovered by students coming out of the dorm building on their way to class. As soon as the body was found, we sealed off the scene and didn't let anyone approach."
Xu Mo stepped forward and lifted the cloth covering the body, briefly observing it.
"Time of death was approximately 10 hours ago... also died last night."
Upon hearing this, Han Fei started to get a headache.
The time of death was also last night. Looking at it this way, his initial guess should be correct.
The deaths of the two victims were very likely connected.
"If they died yesterday, why was it only discovered now?" Wang Dachuan asked, puzzled.
The school leader beside them explained.
"For the safety of the students, the dormitory building has a curfew at night and only opens again the next morning. It was probably too late last night, with no students outside, so the body wasn't discovered."
He paused, then quickly added.
"Before you arrived, we had already identified the deceased student and found his roommate for questioning. According to his roommate's recollection, this student left the dorm room last night and never returned. He probably jumped then. We asked, and his roommate said he was troubled by relationship issues and in a moment of despair he... Officer, please remove the body quickly. If we wait any longer, more students will be coming out, and I'm afraid it will have a bad influence."
When a student commits suicide on campus, the school will certainly bear some responsibility.
To minimize the impact, the school leader naturally wanted the police to remove the body quickly.
In his view, this should just be a case of a student committing suicide due to relationship troubles, a common suicide case with nothing much to investigate. The best way to handle it would be to downplay the incident and resolve it quietly.
After all, having a corpse lying at the foot of the dormitory building would only make the situation increasingly serious.
It could easily lead to some unfavorable rumors spreading.
"This might not be a simple suicide case," Han Fei refused the school leader's request. "We need to examine the situation before deciding. The scene can't be disturbed right now."
Hearing this, the school leader immediately felt overwhelmed.
This isn't a simple suicide case?
From the sound of it, this could potentially be a homicide?
It's important to note that suicide and homicide are two completely different concepts.
A student committing suicide at school could only indicate that the school failed to pay timely attention to the student's mental health.
But a student being murdered on campus? That's an entirely different matter...
"Can you take us to the rooftop to have a look?" Han Fei asked the school leader.
The latter nodded vigorously like a pecking chicken. "Of course, of course!"
At this point, he just wanted the police to quickly investigate the matter and then remove the body, because every minute of delay meant another minute of negative impact.
Under the school leader's guidance, several officers arrived at the rooftop and immediately spread out to search for usable clues.
The situation was, of course, predictable.
Last night's light rain had washed everything clean, leaving not a trace of evidence to be found.
Having found no useful clues, they had to give up.
"Does the dormitory building have surveillance cameras?" Han Fei asked.
"Not on the rooftop, but there are cameras in the hallways! If you need them, I can go get the footage for you right now."
"Alright, please make us a copy."
The school leader nodded. "Then please wait a moment."
With that, he jogged away.
Han Fei stood on the rooftop, surveying the surroundings, then looked down at the body on the ground again. He asked the officers behind him, "What do you think?"
Before anyone else could speak, Xu Mo opened his mouth: "Homicide, and there must be some connection with the case discovered last night. I think we should investigate them together."
