Chapter 305

One-click hot water: he was sitting on the subway, and the bathtub in the bathroom had already begun filling; by the time he got home, he could just step in and soak—wasn't that nice? Tang Jia was the first to speak out against it; after all, this was something she willingly did herself.

Captain Ma snorted.

Wan Baoming quickly said:

Jiang Yuan listened to the others talking while silently sweeping the bathroom. Whether or not the killer had used this system, he had indeed committed the murder and faked the suicide scene—and it had to have been done right in this very bathroom.

This greatly increased the chance of leaving traces. Moreover, Jiang Yuan didn't believe anyone could be perfectly thorough. The killer had invested effort into staging the scene, but that didn't mean he had enough time or energy to eliminate all traces.

Many people hold serious misconceptions about thinking and acting. For instance, how much effort and time would it take for a single person to kill a husky, hang it up, and fake a suicide by hanging? What about cleaning a bathroom? Many people have never even tried a thorough cleaning of a bathroom—if you wanted to clean every corner, leaving not a single trace, how much time and energy would that require? What if you grew exhausted mid-task, fell, and scraped your elbow, forcing you to start over? Some reckless offenders might just give up entirely.

Let them give up—then we'll meet on the execution ground.

All of the above applies to killers who know how to act. Some killers have obvious shortcomings in daily life; killing and erasing traces becomes even harder for them.

For example, some people don't even know how to tie a proper knot. If the noose isn't tied well, lifting a body weighing over a hundred jin leaves you drenched in sweat, and you must be careful not to smudge the corpse's clothes—then, smack! the rope breaks, and the body crashes to the floor. How infuriating, how difficult! Moreover, if the killer wants to stage the scene, many methods become unusable.

Some cleaning agents can indeed destroy DNA, but they aren't common household items, or perhaps the victim's home never bought them—so the killer might have no choice but to risk leaving his own DNA behind. This is the unavoidable risk that comes with the benefits of staging the scene.

Jiang Yuan was now betting that the killer hadn't cleaned the scene thoroughly.

His Level 4 Crime Scene Investigation skill could easily spot flaws left by a Level 2 investigator.

An ordinary killer, without professional training—on what grounds would he leave not a single trace?

Of course, modern people who know what they're doing wear gloves, so fingerprints are probably absent. But Jiang Yuan had collected plenty of skin flakes and hairs from the scene—especially in the drain and sink, where he found short hairs and wiped up water stains.

The victim had long hair; her daughter also had long hair and lived at school. The victim's husband was partially bald, and what little hair he had left was quite long.

The origin of these short hairs was therefore worth serious thought.

Jiang Yuan carefully collected several short hairs, placing each into separate evidence bags, then inspected all the toiletries, and wiped down every suspicious spot with a full box of cotton swabs—finally feeling a bit more at ease.

Compared to determining the time of death, acquiring physical evidence felt far more concrete.

"That's enough. The equipment used to extract data is typically for phones, but other smart devices won't escape it either."

Jiang Yuan and the others stepped out of the room and waited.

The victim's family and several neighbors were taken to the investigation center for statements.

The hallway fell quiet for a moment. Wan Baoming glanced around and said:

Captain Ma was surprisingly cooperative.

The group mumbled near the door.

Soon, the technician walked out, glanced at his notes, and said:

Wan Baoming's face darkened as he turned to the technician:

The technician said:

Tang Jia then said:

The technician replied:

Tang Jia whispered softly:

Captain Ma immediately nodded and added:
