Huo Yaya said: "Uncle policeman, in addition to the road, you can also walk in the woods. If the murderer had walked through the woods, we wouldn't have seen it at all. ”

The road is just outside the school wall, and on the west side of the road is a mixed forest, the depth of the forest is at least more than 300 meters, and the woods are overgrown with shrubs.

There are many deciduous trees in the woods, and the ground is covered with a thick layer of leaves, so even if someone walks in the woods, they will not leave a footprint.

Lao Zhangtou and the five students went back to school, while Principal Xu and his comrades stayed in the woods. Everyone was a little dazed, and the murderer made full use of the special environment of Gujia Datang. The water in the pond and the leaves in the woods hide the murderer's whereabouts.

Principal Xu said that the road to the west of the school, except for students walking, ordinary people will not appear here.

Two shipwrecks lay quietly in an open area in the middle of the woods. Everyone walked up to the two shipwrecks. The footprints of the killer disappeared into the pine forest, which had been completely destroyed by many people who had entered yesterday afternoon.

After a while, two people ran towards the sunken ship, Liu Dayu fixed his eyes and saw that it was Lao Zhangtou and Huo Yaya, they turned their heads at this time, they must have remembered something.

Everyone greeted them, and Ouyang Ping and Liu Dayu walked in front.

"Director Lu, Huo Yaya remembered something." Lao Zhangtou panted and said, "Asia, tell the police uncle quickly." ”

"There is also a person who arrives at the school early, but he never walks through the school gates, so. Daddy Zhang didn't know. ”

"Who is this person?"

"It's Tang Erhu."

"Tang Erhu is in the sixth grade and is a very naughty baby." Old Zhang Tou said.

"Tang Erhu doesn't go through the gate of the school, where is he going?"

"He's over the wall."

So everyone returned to the school's communication room, and Principal Xu personally called Tang Erhu to the communication room.

Tang Erhu's age is about twelve years old, and his height is about one meter six or five, which is much taller than his actual age.

Liu Dayu pulled Tang Erhu to his side and sat down: "Tang Erhu, does your family live at the back of the school?" ”

"That's right! I live in the same village with Huo Yaya and Gu Xiaoming. ”

"I heard that you usually arrive at school early?"

Tang Erhu looked up at Principal Xu, looking very nervous: "I arrived at school early in the morning, I just wanted to copy some homework, and I didn't do anything bad." ”

Principal Xu snorted and laughed: "You stupid boy, the police uncle wants to ask you something, and you can say whatever you know." Don't be nervous, I'm going to praise you. ”

"What do you want me to do?"

"What time did you arrive at school yesterday morning?"

"I'm chasing Huo Yaya and Gu Xiaoming, when they arrived at school, I arrived at school when - I was a little earlier than them."

"Did you climb over the wall to enter the school?"

Tang Erhu looked at Principal Xu, and then nodded.

"Did you see anyone on the way?"

"On the road, I didn't see anyone, but I saw a man in the woods."

"You saw a man in the woods?"

"That's right! I went into the woods and. ”

The murderer walks deep in the woods, and it is only in the woods that it is possible to encounter the murderer.
