Chapter 89 Trace Evidence

"Sister Wanwan, have you written it all down?"

Feng Nan looked up at Ye Wanwan.

Ye Wanwan nodded: "I've got it."

"This puddle is about 1.5 meters deep, and the deceased was about 1.8 meters tall. Theoretically speaking, even if someone was pulling him from below, it would be difficult for him to drown. After all, when you step into the water, there are still 30 centimeters above the surface, meaning the part above the mouth would be above the water. Isn't this the primary crime scene?"

Ye Wanwan bit her pen and asked in confusion.

Ye Wanwan looked puzzled.

She couldn't understand how a tall man, 1.8 meters tall, could drown in a water pit that was only 1.5 meters deep, without showing much sign of struggle.

Hearing Ye Wanwan's question, Feng Nan smiled slightly: "We need a forensic doctor to do an alcohol test on the deceased. The deceased drank a lot of alcohol before his death, and I deduce that the alcohol contained sleeping pills."

"As for how a tall man of 1.8 meters drowned in a 1.5-meter-deep puddle, that's simple enough."

"Let alone drowning a drunkard, or even a drunkard under the influence of sleeping pills, even a normal person, as long as there is someone in the water who is an excellent swimmer, can pull the deceased horizontally with enough strength, and drown a tall man who is 1.8 meters tall in a 1.5-meter-deep puddle."

"The reason why the murderer made the victim drink a lot of alcohol and put sleeping pills in her mouth before committing the crime was twofold: first, to create the illusion that the victim had drunk too much and accidentally fell into the water; second, because the murderer was a woman and there was a huge disparity in strength between her and the victim, she was not confident that she could drown the victim directly. She was afraid that the victim would struggle and resist, which would pose a threat to her. After all, even a strong swimmer would be dragged to death if grabbed by someone who is about to drown."

Feng Nan vividly recounted the events of the case, the murderer's psychology, and the process of the crime, leaving Ye Wanwan and Xiao Li dumbfounded and bewildered.

Feng Nan's account was incredibly detailed.

The expressions were also very vivid.

Ye Wanwan and the others felt as if Feng Nan was present when the murderer committed the crime.

"what happened?"

Why are you all looking at me like that?

Feng Nan blinked and asked curiously.

"No, it's nothing."

"If I weren't sure, I would have thought you were there last night since you were with me the whole time."

Ye Wanwan shook her head and smiled wryly.

Feng Nan was taken aback at first.

She then smiled gently: "What are you thinking about?"

"Why would I do something so pointless?"

“If I wanted to commit a crime, I wouldn’t make such a basic mistake and leave so many loopholes.”

Feng Nan felt somewhat helpless about Ye Wanwan's boundless imagination.

At the same time, I secretly reflected on whether I had revealed my antisocial tendencies in my daily life.

How did Ye Wanwan come to have this idea?

"Have you written it all down?"

Feng Nan didn't want to dwell on this issue too much.

He asked Ye Wanwan.

"I've got it, I've got it."

Ye Wanwan came to her senses and realized that she had actually been doubting Feng Nan.

"These can be used to reconstruct crime scenes and are also very useful when interrogating suspects."

Feng Nan added, emphasizing the importance.

Ye Wanwan naturally understood this as well.

He nodded repeatedly, indicating that he understood.

Feng Nan got up and left the body.

Walk towards those footprints that circled around the reeds again and again.

She squatted down, pretended to reach out and measure the footprints, and observed them for a while: "Sister Wanwan, come and look at these footprints."

Ye Wanwan and Xiao Li immediately gathered around, waiting for Feng Nan's mini-lesson to begin.

Have all these footprints been collected as evidence?

Feng Nan asked.

Ye Wanwan turned to look at Xiao Li.

He gestured to Xiao Li to answer quickly.

"The technical investigation team has taken photos and collected evidence, and made footprint rubbings. Through preliminary comparison, the footprints match those on the victim's shoes found in the water," Xiao Li replied immediately, understanding the implication.

Feng Nan nodded: "The footprints were indeed made by the deceased's shoes, that's for sure. But from the pressure points, compared to the wear marks on the shoes, the pressure points of these footprints don't match."

"I can deduce that this was not made by the deceased himself, but by the murderer wearing the victim's shoes, imitating the deceased's gait, and pretending to make the footprints to confuse the detectives."

At this point, Feng Nan paused for a moment.

He looked up at Ye Wanwan and Xiao Li.

Allow enough time to digest the knowledge points.

"You wrote everything down?"

After waiting for a minute, Feng Nan asked in return.

Ye Wanwan and Xiao Li nodded repeatedly, like chickens pecking at rice.

These aren't the knowledge points of ordinary detectives, but rather the knowledge points of criminal investigation experts, which they wouldn't normally learn.

Not to mention the opportunity to observe and listen to explanations in person.

Even learning just a little bit will be incredibly beneficial to their future careers.

You might just achieve something unexpectedly.

It's the key to getting a promotion and a raise.

Feng Nan nodded and continued, "From the point of force application, we can see that the murderer was wearing oversized shoes."

"The deceased's shoes were size 44, while the murderer's shoe size was at most 36 to 36.5. He often wore high heels, his toes were slightly deformed, and he took very small steps."

At this point, Feng Nan stood up.

Next to the footprints, he imitated the action.

"As I just demonstrated, although the murderer tried to imitate the victim's gait, it was still not enough. The second set of steps I imitated was the murderer's most comfortable walking gait."

"Judging from the gait, the murderer's height should not exceed 1.65 meters, weight should be between 48 and 55 kilograms, and he should have a good physique, be good at sports, and be dressed beautifully and fashionably."

At this point, Feng Nan clapped her hands.

"Alright, the murderer profile is complete."

"You can start screening and making arrests now."

"As long as we find this woman, we won't have arrested the wrong person, and we can definitely close the case today."

Feng Nan said confidently.

Feng Nan really couldn't reveal any more information. If this still didn't catch the murderer, Feng Nan would be helpless. She was just short of giving the murderer's ID number so she could sketch out a picture of him.

"Xiao Li, the scene is in your hands."

"Take the body back and have the forensic doctor work overtime to test for the alcohol and sleeping pills that Xiao Feng just mentioned. We're leaving now."

Ye Wanwan called out to Xiao Li.

He pulled Ye Wanwan away.

Now Ye Wanwan feels like she's back to normal.

She was finally able to solve cases independently.

And the murderer was apprehended within a day.

It topped the record for the fastest case solved by the Major Crimes Unit.

Pulled along by Ye Wanwan, Feng Nan quickly ran out of the reeds, shaking his head and smiling bitterly.

Feng Nan thought he wouldn't need to be involved in the arrest, but unexpectedly, Ye Wanwan still conscripted him to help arrest the suspect.

Ye Wanwan opened the car door.

"Princess, please get in the carriage."

Ye Wanwan said with a grin.
