After announcing he would explain Bao Qingshan's crime process, Lin Chen caught everyone's full attention, and the tense gazes of Bao Qingshan and his wife focused on him.
Miao Zhengxiong stroked his chin thoughtfully and murmured, "It's really impressive that such subtle clues can be uncovered."
Under the watchful eyes of everyone present, Lin Chen began, "Bao Qingshan, you and the victim were friends. After he convinced you to invest, you made two investments and earned profits."
"When he asked you to invest a third time, you trusted him again and invested all your savings, believing it would be profitable. Unfortunately, all the money was lost."
"You resented him, had two heated arguments with him, but your anger and losses remained unresolved. So you carefully planned this murder."
"I didn't kill him. Even if I hated him, I wouldn't have the guts," Bao Qingshan replied seriously, his expression heavy as if close to tears.
Lin Chen ignored Bao Qingshan's denial and looked at Miao Yunfei and Zhang Tian'ai. "Do you remember when I was at your house, and you told me the rooftop was being extended, that's when I became certain this was a murder?"
"Yes," both Miao Yunfei and Zhang Tian'ai answered in unison.
"I thought so because although the victim's shoes had some dust and dirt on the soles, there was no sand or cement residue."
"The anti-slip grooves on those shoes are about 4 to 5 millimeters deep and about 1 millimeter wide. Such grooves easily trap sand and gravel. Now, look at the victim's fall location—there's a pile of Sea Sand there. If the victim jumped from there, he would have to step on that Sea Sand."
Zhang Tian'ai's mouth slightly opened in surprise. "Lin Chen, you even examined the soles of the victim's shoes and remembered the exact width and depth of the anti-slip grooves…"
Others also deeply agreed.
Lin Chen pointed to his head with his index finger. "Because I have a good memory."
He continued his reasoning: "Bao Qingshan, after planning the murder, on the day of the incident, after your wife went out, you bought some snacks and strong liquor."
"I don't know what you said to the victim, but you must have sat down and got him drunk. Then you went to the door to check if anyone was coming or going."
"The victim's room was on the eighth floor near the stairwell, so it was easy to watch for passersby to avoid being seen when you brought him upstairs."
"There's no sand on the victim's shoes because you carried him up. Considering the victim's size, carrying him and placing him on a 1.2-meter-high railing was quite difficult for you."
"So you chose the side of the railing with the pile of Sea Sand, which was already compacted and about ten centimeters thick."
"You stepped on that pile while carrying the victim. Your weight plus his was nearly 150 kg, so a lot of Sea Sand stuck to your shoe soles."
"How did you make the victim fall at ten o'clock? There was no rope or anything found," a young detective asked.
"Follow me," Lin Chen said.
He led everyone back to the spot where the victim fell. Pointing to some broken bricks on the railing, he said, "Bao Qingshan used these."
"Broken bricks?" the landlord asked puzzledly. "How can broken bricks kill someone?"
Lin Chen explained, "He laid the victim flat on the railing, then placed some sharp broken bricks underneath the victim's body on the inside of the railing."
"The victim was drunk and asleep, so he didn't feel the discomfort at first. After a while, as his mind cleared a bit, he felt the discomfort from the bricks."
"When a person feels something uncomfortable under their body while sleeping, the natural instinct is to turn over to avoid it."
"If it were a bed, that wouldn't be an issue. But the victim was lying on a rooftop railing. When he turned to get away from the uncomfortable side near the rooftop interior, he flipped outward over the railing and fell from the ninth floor, dying instantly."
Hearing Lin Chen's reasoning, Miao Yunfei, Zhang Tian'ai, and the other detectives showed expressions of sudden understanding.
So that's how the victim died. Bao Qingshan's method was truly ingenious.
Miao Zhengxiong stared at Lin Chen, mentally replaying his words, deep in thought.
Lin Chen locked his gaze on Bao Qingshan's ashen face and said, "After placing the victim on the railing, you must have been very nervous. People with a smoking habit often reach for a cigarette to calm their nerves when extremely anxious."
"So you went over there, lit a cigarette, took a few puffs, and stubbed it out on the railing, then carelessly tossed the butt down below, thinking no one would notice. Unfortunately, it was found."
"Afterwards, you cleaned up the traces of your presence on the rooftop, then went back inside the victim's room and wiped away all your fingerprints."
"Once done, you hurriedly left and returned home."
"Judging by your wife's current expression and my earlier observations, she was unaware of your actions. You kept her in the dark, fearing she might slip up when facing the police, right?"
