The departure of Niuniu's parents has an impact on the case equal to zero, and even their departure facilitates the continued investigation of the case and Niuniu's continued search.

Lin Yu, Zhang Boer and Li Sanyi were arranged by Fengyin to swipe their mobile phones, so that it was convenient to observe the heat of the Niuniu incident.

Preferably, it can reduce some heat.

Wind Yin is involved in the work of investigation, inquiry, analysis, and search.

They targeted an old man in his fifties, alone, his wife died early, and someone saw him talking to Niuniu, not once, but several times.

Coincidentally, the old man came down from the mountain at about nine o'clock in the morning, and was not in the village at the beginning.

This time, his suspicion is even greater.

The man was detained for questioning, but he said nothing and did not admit anything.

At the same time, Feng Yin followed the investigation team into the man's home, looking for all possible information.

The man's home was not clean, messy, disorganized, dust piled up into mud, and it should have been smooth tiles, but the original pattern was not visible on it.

Piled up with dishes and chopsticks, there are even maggots crawling on it, and next to it is a bucket of unknown material, and the dirt on the side of the bucket exudes a disgusting smell.

"There's a discovery here!"

The investigation team, which thought it would waste a lot of time searching, found clues as soon as they entered the bedroom.

The man probably didn't expect someone to come to his house and enter his room.

Also, through the villagers' accounts, the man's house was very dirty, and they were reluctant to go.

Inside the house, directly facing the door, was a computer, which had been turned on and several video files had been opened.

"It's Niu Niu!"

The environment in the video is Niuniu's home, with Niuniu lying on the bed, and the angle of this video is obviously the position of the rabbit doll before.

The evidence is ironclad.

The members of the investigation team contacted Officer Zhao as soon as possible, so that the interrogation could be carried out smoothly.

But even if a lot of things about Niuniu were found in the video files and in the house, when they were placed in front of the man, the man still didn't say a word.

Refuse to cooperate!

The interrogation was again at an impasse.

Feng Yin didn't go inside, but looked through what had been found in the man's room.

"Can you give me a map of the mountain?"

"Good!"

A map was laid out on a flat table, and Wind Yin took a pen and began to analyze it.

"Niu Niu left at one o'clock in the morning, and the earliest time the man was seen this morning was nine o'clock, coming down from the mountain."

"It was foggy and rainy in the second half of the night yesterday, and the soles of these shoes were still wet, probably the shoes that men used to go up the mountain, the earth was yellow and black, and the leaves were red... Not much. ”

Feng Yin circled a place on the map with a pen, and the tip of the pen clicked in the circle.

"The receipts here prove that the man bought tools for the outdoor fire, ropes, and no tents or anything like that, and I guess he would have chosen a cave that already exists."

"Since it is a cave that already exists, it must not be widely known, and it must be very remote......"

The pen in Feng Yin's hand drew a circle again, and the range pen was much smaller before.

"Take it in and let Officer Zhao test it."

A policeman next to him quickly understood that this was a common method in their interrogation, fishing.

The map was taken in, and a minute later, Officer Zhao led people out and looked at Fengyin.

"Together?"

"Good!"

Feng Yin followed Officer Zhao and his party and immediately set off for the mountain, hoping that everything would still be in time.
