The case information says that only the first floor is monitored, so the other floors upstairs are not monitored, that is, the murderer can freely shuttle between the stairs without entering the elevator, which is the key to solving the case. Pen & Fun & Pavilion www.biquge.info

The next is the details of the corpse, the neighbor's testimony on the data has said everything, the neighbor couple said that there has been more garbage recently, and the other two neighbors also like to put the garbage outside the door, in fact, not only those two neighbors, in our lives, there are many people who like to put the full garbage bag outside the door, wait for the next morning, or the next time they go out, throw it out.

And the cleaning aunt's mood is also because of the garbage bag, because the cleaning aunt's dissatisfaction, is to show that the garbage in the corridor is useless, for the cleaning aunt, the disposal of renewable garbage is a very happy thing, because renewable garbage can be sold for money, then the cleaning aunt is very unhappy, it means that the garbage in those corridors are non-renewable, and there are a lot of them.

The murderer took advantage of some people who like to put garbage bags outside the door to throw the corpse, and the murderer put the stumps of the deceased into those non-renewable garbage bags, such as kitchen garbage, toilet paper, etc., so that the cleaning aunt will not rummage, and others will not rummage through these annoying garbage.

The killer put the stump of the deceased into these non-renewable garbage bags, and used other residents and the cleaning aunt to throw the garbage bags out of the apartment, so that the impossible method of throwing the body was easily completed.

But after all, not all residents like to put garbage bags outside the door, so the murderer made some non-renewable garbage bags and threw them in the corridor, and the cleaning aunt will definitely dispose of the garbage, so it is seamless.

Li Ming sorted out the above information and ran back to the police station happily, and at this moment, Xu Tiancai suddenly remembered that he had to go far away.

Compared with the case brought by Li Ming, the trouble Xu Tian encountered this time was even more confusing than the method of throwing the corpse, and the matter had to start with the express delivery that Xu Tian received.

Before Li Ming came, Xu Tian had been pondering the tape in the courier, there was only one old-fashioned tape in the entire courier, and the sending address was still the mountain village of his hometown.

Inside the tape was a recording of a little girl, but because the tape and Xu Tian's old-fashioned repeater were old and damp, the voice sounded blurred.

The little girl was telling about the events before her mother died, and after Li Ming left, Xu Tian took out the tape in the drawer again and put it in the repeater.

"Today, the ghost mother-in-law came to change my mother's dressing, it was so scary, my brother and I didn't dare to go back to the house."

"At noon, Grandpa Paper came, and he was going to take my brother away, and my mother and I cried."

"Uncle Sugar ran out of the house in the afternoon, and Mom died, woo woo ......"

These three sentences made Xu Tian feel that it was the testimony of the little girl who witnessed the killing of her mother, and one of those three people must be a murderer, and the most suspicious thing is the last Uncle Sugar.

But the next recording is the point, before the next recording appears, there is a clear key sound is recorded, and there is a "sudden" sound, obviously the two recordings were not recorded at the same time.

After the little girl's monologue, it was a woman's voice, with a thin voice, a processed voice.

"Hongmei is back, the first person is dead, no one wants to escape, haha...... Hahaha......"

Followed by a little girl's soft humming, the tone was very poignant and terrifying, and Xu Tian had goosebumps when he heard it.

Xu Tian called the sender back, but the other party was the public phone of a small store, which made Xu Tian very distressed.

Buzzing......

The vibration sound of the mobile phone text message broke Xu Tian's panic, and it was another express mail, Xu Tian took it back and opened it to see that it was a letter written by his grandmother.

Xu Tian's hometown is located in the mountains, is a small mountain village without a network, the population is only about 300 people, the grandmother in the hometown is Xu Tian's biggest concern, although Xu Tian's parents thought about picking up the old man to the city, but the grandmother has been unwilling to come, because the grandmother has the mission of staying in the mountain village, and the grandmother is an old village doctor.

The letter wrote that Xu Tian's second grandfather, that is, Xu Tian's grandfather's younger brother, died a week ago, and according to Xu Tian's grandmother, the cause of death was excessive fright, and he was scared to death in the corner of the courtyard wall when he went to the toilet at midnight.

According to the rules of the hometown, those who die of such unnatural and disease must be mortuary for half a month before they can go out of the funeral, and the soul of the deceased must be exceeded during this half month.

According to the time of the mail, it was a week ago, but Xu Tian deduced that the letter must have been sent by his grandmother the day after the death of the second master, so it may be that the second master has been dead for eight days.

The two couriers were sent half a day apart, and at this time, Xu Tian remembered what the woman in the tape said, "The first person is dead", what does this have to do with the death of the second master?

Xu Tian hurriedly called his father.

"Hey! Dad, grandma wrote to say that the second master is dead, but that's not the point, I want to ask, do you know Hongmei? ”

As soon as Xu Tian's voice fell, there was a sound of the phone falling on the other end of the phone.

"You...... Why do you ask this? I know about the death of your second grandfather, and I also received my grandmother's letter, but grandma said that she wouldn't let me go back, just named you to go back by yourself, you also know grandma's character, and there must be a reason for her to decide, so you should leave immediately. ”

"Dad! I asked, do you know the red girl? This matter is important. ”

"You remember, that name must not be mentioned when you return to the village, especially in front of the old people in the village, do you know?"

Then Dad hung up the phone in a hurry, Xu Tian thought about it, and couldn't figure out why Dad was perfunctory, but since Dad didn't want to say it, he had to go back and ask Grandma.

After Xu Tian listened to the tape again, from side A to the end of side B, there was no more women's voice, they were all old songs from the early nineties.

Xu Tian rewinded the tape back to the beginning, and the sound of the repeater was turned to the maximum, because the repeater and the tape were both old, the sound was very vague, and the noise was also very loud.

First it was the little girl's monologue, then there was a "sudden" sound, then a woman's voice, and when the girl's humming appeared, Xu Tian pricked up his ears and listened carefully.

In addition to the girl's humming, there were a few noisy voices, but the voice seemed to be far away, and the girl's humming voice also seemed to float from a distance, not like it was deliberately matched.

Xu Tian understood, this must be the woman who accidentally recorded someone else's voice during the recording, which is the key evidence to find the sender.

And why the sender can know his address, Xu Tian has already guessed a rough idea.

It must have been grandma who saw her address by the sender when she sent the shipment, and why did this tape arrive half a day earlier than grandma's letter? Xu Tian still didn't understand this too much.

Pack your bags and go.

After five reversings, Xu Tian finally came to the small mountain village that had been absent for a long time, Xu Tian was just sensible when he left last time, but he was still very impressed by the high mountain around his hometown, especially the two-story small white building outside the mountain, which was the only way for the village to communicate with the outside world.
