"I'd like to ask, do you have any food for cats in your house, other than cat food?"

Lin Yao looked at Bai Ling and asked.

They had already inspected Bai Ling's residence, and only cat food was found.

However, the substances detected on the screen of the mobile phone do not match the cat food.

"Other food?"

Bai Ling frowned slightly, then shook her head and said:

"No, I only give it cat food, not other messy things."

"You guys. . . Why do you ask this?"

Then, Bai Ling's gaze looked at Lin Yao and them.

"We suspect that the post was sent by your cat."

Lin Yao looked at her and said directly.

"Huh? What?! A post sent by a cat!"

After listening to Lin Yao's words, Bai Ling and her father both widened their eyes and asked rhetorically.

"Comrade policeman, you're kidding, aren't you?"

After a moment, Bai Ling's father stared at Lin Yao and asked.

Lin Yao shook his head slightly and said:

"I'm not kidding."

Then, Lin Yao's eyes were firmly fixed on Bai Ling, observing her subtle expressions.

At this moment, Lin Yao felt that in addition to surprise, Bai Ling's face seemed to have a trace of panic.

Lin Yao didn't know if this was his own delusion.

"Comrade policeman, then you won't say that this cat raised by my daughter is a murderer, right?"

Bai Ling's father stared at Lin Yao in disbelief.

Could it be that the cat has become a sperm?!

Lin Yao couldn't help but laugh after hearing this, and said:

"I didn't mean that."

After saying that, he stood up directly, and then said:

"We may come to you often during this time to understand the situation, and please bear with me."

After Bai Ling's father heard this, he also quickly got up from the sofa and asked:

"It's fine, it's fine. Comrade policeman, are you going back?"

"Yes."

Lin Yao nodded.

This time, Lin Yao wanted to ask Bai Ling if Bai Ling knew about the food on the mobile phone screen, and on the other hand, he wanted to see how Bai Ling reacted after hearing this.

After all, this cat is her own.

"Comrade policeman, don't be in a hurry to leave, let's finish eating here first!"

Bai Ling's father said enthusiastically.

And Bai Ling was still sitting on the sofa, as if she was thinking about something.

"No need, we might be here again tomorrow, haha."

Lin Yao said with a smile.

"Okay, welcome, welcome!"

After finishing speaking, Bai Ling's father sent the two of them out.

After coming out, Yao Jin glanced back, and then said to Lin Yao:

"Brother Yao, you won't suspect that this Bai Ling is suspicious, I just saw your eyes staring at her tightly."

"It's not that she's suspicious, but that all the people involved in this matter are now suspicious."

Lin Yao said casually as he walked,

"Now since Bai Ling doesn't know what the substance on the phone screen is, then we can only find it ourselves."

"Well, where are we looking?"

Yao Jin nodded, then asked.

"You say, of course I went to the pet store, and I can't find this thing in your house."

Lin Yao said directly.

Yao Jin smiled awkwardly and said:

"Yes, yes, let's go, I'll navigate and see if there's a pet store nearby."

"But. There are so many of these things like this in pet stores, how do we know which one?"

Subsequently, Yao Jin threw out questions again.

"Don't worry, doesn't this thing smell?

I've smelled the residue on the phone screen just now in the Tech Squadron."

Lin Yao said to him.

"Holy! You're a dog."

Yao Jin was surprised, and then said that this stopped.

"That's right, I'm a dog's nose."

Lin Yao said directly, opened the car door and got into the car.

"Okay."

Yao Jin was slightly stunned, then nodded.

I have long heard that the anti-pickpocket tiger has thaumaturgy, and he really can't be treated as an ordinary person!

After getting in the car, Yao Jin found a pet store and drove straight over.

"Hello, hostess!"

Lin Yao and the others walked in, and the proprietress inside quickly stood up from the chair behind the counter and looked at them suspiciously.

After a moment, she immediately said:

"Comrade policeman, our business licenses and the like are complete! What procedures do you want to check?"

"No, no, don't get me wrong."

Lin Yao hurriedly waved his hand, and then said:

"We want to ask, where is the food that cats eat?"

"Cats? The food you eat?"

The proprietress was slightly stunned, then reacted, and hurriedly said:

"Oh! Are you going to buy something?"

"Well, almost."

Lin Yao nodded.

"Oops, scare me, I thought you were going to check my shop!"

The proprietress clutched her chest and breathed a sigh of relief.

"What? Do you have any formalities?"

Lin Yao raised his eyebrows and looked at her and asked.

"Ah, no, no, aren't you afraid of checking if you're all compliant, how troublesome."

The proprietress said with a smile, then pointed to the shelves against the inner wall and said:

"The cat's food is over there, you guys come with me."

Lin Yao and the two glanced at each other, and then walked over.

I saw a dazzling array of cat supplies on this shelf.

"Are you going to buy cat food or something?"

The proprietress looked at them and asked.

"It's not cat food, it's cat food, something that attracts cats to eat."

Yao Jin immediately said to the proprietress .

"In that case."

The proprietress frowned, thought for a moment, and then said:

"That's the cream?"

"What is a nutritional paste? We don't have cats, we don't know much."

Yao Jin asked suspiciously.

"Don't have a cat? So you buy this?"

The proprietress asked as she walked towards the shelves.

"Give it away."

Yao Jin didn't say much, and replied directly.

"No, that's what it is."

The proprietress took out a small box from the shelf, handed it to Yao Jin's hand and said.

Yao Jin opened the box outside, saw the vial inside, and then asked:

"Does this thing do anything? Cats love to eat?"

"Yes."

The proprietress nodded, and then said:

"It's a paste, cats love to eat it, and it can replenish the nutrients they need in their bodies."

"Show me."

Lin Yao stretched out his hand towards the nutritional paste in Yao Jin's hand.

"Here you go, Brother Yao."

Yao Jin hurriedly handed it over.

Lin Yao took the nutritional paste to his nose and sniffed it vigorously.

"This package hasn't been opened, can you smell anything?"

Yao Jin looked at Lin Yao suspiciously.

"No problem."

After Lin Yao smelled it, he handed the nutritional paste to the proprietress hand.

"Are there any other flavors?"

Then he asked.

"Yes."

"Take it all out and put it here."

Lin Yao pointed to the counter and said.

After a while, there were more than a dozen kinds of nutritional pastes on the counter.

Lin Yao took them and sniffed them one by one.

Then, his expression became solemn.

"How? Brother Yao."

Yao Jin asked with his eyes fixed on him.

"That's it."

"What?"

"I said this is the one!"

Lin Yao said affirmatively.

Then, he looked up at the proprietress and asked:

"Boss, how much is this? We bought it."

"Okay, I'll put it up for you."

The proprietress was already confused by Lin Yao's operation at this time, so she hurriedly took out the bag from the side.

"Don't bother, that's it."

After finishing speaking, Lin Yao paid the money and walked out with the nutritional ointment.

After a while, the two of them came to the door of the technical squadron.

"I brought the thing, you quickly check if it is consistent with the residue on the phone screen."

After walking into the office, Lin Yao directly took out the nutritional paste and said to the technician.

"Officer Lin, you're back, and I'm still looking for you."

After one of the technicians saw Lin Yao, he hurriedly said.

"What's wrong?"

Lin Yao couldn't help but look at him suspiciously.

"We examined the corpse just now, and we found some discoveries."

The technician said, and then he added:

"I'll talk about this later, the cat brought it, let's test it first."

"Xiao Liu, hurry up and bring the cat!"

"Here, this cat doesn't recognize life at all, and it's almost licking my bald skin!"

Xiao Liu came over with the cat in his arms and put the cat on the table.

Subsequently, a technician took some of the nutritional paste that Lin Yao brought back and took it for testing.

"Quick, squeeze into your phone."

Lin Yao said with the nutritional ointment, and then he turned his head to Yao Jin:

"Yao Jin, take out your phone."

"Huh? Brother Yao. How do you use me, don't you have a mobile phone?"

Yao Jin frowned, clutched his mobile phone, and said embarrassedly.

"I don't have that forum software on my phone."

"Okay."

Yao Jin had no choice but to reluctantly hand over the phone.

"Unlock!"

Lin Yao didn't have time to talk nonsense, after Yao Jin unlocked it, he directly opened the forum, and then edited a post casually."

Immediately after, he squeezed the paste onto the send button.

"Alright, let the cat go."

Lin Yao glanced at Xiao Liu and said to him.

"yes, okay."

After Xiao Liu let go of his hand, the cat finally regained its freedom, and it first looked around, staring at the few people present.

"It seems to be a little scared of life and can't let go, so let's retreat to the back first."

Yao Jin glanced at everyone and said.

Afterwards, everyone stayed away from the cat.

The cat withdrew its gaze and looked at the mobile phone in front of it.

Then, it slowly leaned over and sniffed at the nutritional paste.

Lick, lick!

Everyone stared at the cat, and they were secretly anxious in their hearts.

At this moment, the cat suddenly stretched out its tongue and licked the nutritional paste on the screen.

Everyone stared closely, and after a while, Lin Yao saw that it was almost there, and then said:

"Okay, that's it, hurry up and see if the post has been sent!"

After hearing this, Yao Jin hurriedly ran to his mobile phone.

"Holy! The tempered film of my mobile phone is wasted, it's disgusting."

Yao Jin looked at his phone with a disgusted expression.

"Don't pay attention to this, hurry up and see, has the post been sent?"

Lin Yao immediately asked in the back.

"I'll see! I actually sent it out, and that's okay!"

Yao Jin looked at the screen carefully, and suddenly shouted excitedly.

The crowd also came together.

At this moment, the technician who had just taken the nutritional paste for the test also came back.

"After testing, the composition of this nutritional paste is consistent with the residue on the deceased's mobile phone film."

Hearing the technician's words, everyone gasped.

"In that case, the killer edited the post first, and then applied this nutritional paste to the position of the send button, let the cat lick it, and then send it out?"

Then, Yao Jin reacted and couldn't help but ask.

"But..."

Immediately afterward, he couldn't help but wonder,

"Even if it's put on the screen, the cat will come to lick the food soon, and it won't buy much time for the murderer!"

"I don't think it makes a lot of sense for him to do this."

Lin Yao stared at the cat, shook his head slightly, and said:

"No, he put his phone under the couch with the cream on it, and the cat won't be able to find out about it in the first place."

"By the time it finds out, maybe ten minutes have passed."

"Don't underestimate these ten minutes, ten minutes is enough time for the murderer to escape."

Everyone couldn't help but nod slightly.

"In that case, the murderer has set a time gap."

Yao Jin frowned and said,

"However, we understand the principle of sending posts, but it is not very useful for the progress of solving the case."

Lin Yao didn't say anything, but turned his head to look at the technician and asked:

"What did you just tell me you found?"

"Oh, that's right."

The technician thought about it and hurriedly said:

"We tested the deceased's stomach and found that there were undigested fried chicken residues, bread residues, and potato residues in his stomach."

"In that case, it means that the deceased must have eaten Kender chicken or something before he was killed?"

Lin Yao frowned slightly and analyzed.

"Where is the deceased's phone? Show me."

Immediately after, Lin Yao asked again.

"Here."

A technician brought over the phone in a clear bag.

"We've had the relevant personnel hack his phone, but we haven't checked the information inside, so come on."

The technician said to Lin Yao.

Lin Yao nodded slightly, and then took the phone.

After a moment, he couldn't help but frown.

"What's wrong, Brother Yao?"

Yao Jin couldn't help but ask when he saw Lin Yao's expression.

"I just read the information in his takeaway software, and on the morning of the day of the crime, he ordered an order of Kende Chicken outside, and the delivery address was. Bai Ling's address."

Lin Yao stared at his phone and said with some hesitation.

"Bai Ling's address? So, did he eat Kende chicken at Bai Ling's house?"

After Yao Jin heard this, he couldn't help but guess,

"In other words, Bai Ling still left him at home for dinner?"

Lin Yao continued to check his phone, and then said:

"Let's go find the delivery guy who delivered Kende chicken first, and ask him if we want to."

"Well, that's right, where did he place the order?"

Yao Jin nodded in agreement.

"It's near Bai Ling's house, let's go, let's go now."

"Good!"
