In her past life, although Tina Shen was skilled at solving cases, her real expertise lay in... simulating criminals!
Simulating the criminal's psychological activities, simulating the criminal's actions, simulating the criminal's... everything!
Kevin Guo, standing nearby, suddenly felt the cold aura emanating from Tina Shen and was taken aback. As an experienced criminal investigator, his sharp eyes could always notice subtle changes in others, picking up on things that ordinary people might miss. Tina Shen's sudden shift in demeanor truly startled him.
"Mentor, don't worry. I'm just mimicking the criminal's mindset," Tina Shen explained while walking into the employee dormitory. "It's time to show my real skills..."
Kevin Guo, trailing behind her, looked puzzled. He didn't quite understand, and didn't press the matter further. However, he had an inkling that something was off with his apprentice. He understood simulating a crime scene, but mimicking the criminal's psychology—what kind of operation was that? Could someone really imitate another person's thought process?
What Kevin Guo didn't know was that the young woman in front of him was a time traveler. In her past life, she had been a bona fide police officer, and her specialty was simulating the criminal mind. She had solved numerous major cases using this skill.
"Let's assume I'm the killer…" Tina Shen stood at the door of the victim's former dorm room and pushed the door open.
Inside was an eight-person dormitory. Employee dormitories weren't like university dorms, and it was common to have so many people living in one room. She walked over to the spot where the victim's bed had been.
"It was night when it happened, and based on the victim's game records on his phone, he was likely lying in bed playing games at the time," Tina Shen murmured to herself. "On a winter night, a normal person wouldn't want to get up. Even if someone called, they usually wouldn't go outside unless there was some special reason to follow the killer..."
What could have made someone follow another person in the middle of the night, willingly go to the rooftop, and stand out in the cold wind? Was it temptation? A threat? Or hatred?
As for greed and profit... the victim was just an ordinary employee with no access to those things. Otherwise, he wouldn't have been working overtime at a small factory during the holidays. Additionally, the victim had a cold at the time and had been resting in the dorm.
Temptation? That seemed unlikely. The only two female employees in the dorm were both of average looks. Besides, who would go to the rooftop to hang out in the dead of winter unless they were out of their mind?
So, that left two possibilities: a threat or hatred. If one person threatened another, they would either have leverage over them, be in a position to dominate them, or have been suppressing them in daily life.
Hatred, though... It was simple to consider. No, it couldn't have been hatred. If the victim had enemies, the police would have found out by now. The victim had been working at the factory for over six months and had a good reputation. He was liked by many people, was good-looking, and had even caught the interest of a few female employees—this was all information the police had gathered.
"A threat?" Tina Shen squinted, murmuring to herself. "If I were the killer, what would I do to threaten someone and get them to come with me to the rooftop?"
"Wait... no, why would I threaten an ordinary employee? What is it that would make me absolutely need to kill them?"
"Murder must have a reason. If I'm angry enough to kill someone, they've definitely violated some sort of interest of mine."
"Looking at it from the victim's perspective, money doesn't seem likely. He didn't have a history of bad behavior... Could it be a romantic dispute, some sort of love triangle?"
Could conflicts between men and women really lead to murder?
Ha! Of course they could. In past homicide cases, at least 15% were due to romantic disputes. The most common scenario was a partner being betrayed, which then led to murder!
"Was the killer cheated on?" Tina Shen's face took on a strange expression.
If the killer were a man, and discovered he had been cuckolded by the victim, then it's possible the killer confronted the victim, exposed the betrayal, and then threatened the victim to follow him—could this be the case?
Yes!
For now, let's proceed with this assumption and continue reasoning.
I am the killer. I lead the victim to the rooftop...
On the rooftop, Tina Shen stood at the spot where the victim had fallen before death.
"If I were the killer and specifically chose this time to lead the victim to the rooftop... It's obvious," Tina Shen's eyes flashed with a dangerous gleam. "I'm here to kill!"
Before committing murder, the killer would surely have planned everything carefully. So... the killer must have prepared the weapon beforehand. The weapon should have been hidden on the rooftop before meeting the victim. Otherwise, how could the victim have followed the killer without seeing the weapon?
Tina Shen looked up and surveyed the surroundings. The police had already searched the crime scene countless times, but they hadn't found the weapon. However, since the killer had to transport the body after the murder, carrying a blunt instrument that could kill would be inconvenient.
This meant the weapon was likely still at the scene. If I were the killer, where would I hide the weapon before committing the crime? And where would I hide it after the crime?
Tina Shen's eyes scanned every corner of the rooftop inch by inch. The small base station, the small storage room, the pile of garbage, the ventilation shaft, and the drainage pipes...
Tina Shen began to conduct a thorough search, not letting any corner go unchecked. Eventually, she stopped in front of one of the drainage pipes.
For any building, to prevent water accumulation on the rooftop, drainage pipes were always installed. This dormitory had four drainage pipes at the four corners of the rooftop. These places were often overlooked because they didn't seem like a spot where anything could be hidden.
But...
Tina Shen started inspecting the first drainage pipe, then moved to the third one.
In an instant, her eyes lit up. When her hand slowly reached down from the connection point between the drain and the pipe, a faint black-purple stain appeared on her fingernail—the dried blood.
She had found it!
