The mobile phone information of the deceased Chen chrysanthemum has been extracted.

Half an hour later.

Zhong Tianzheng met the person who spoke to her that night.

The other party was also a woman of the same age, 51 years old. When talking about last night, she was obviously a little unhappy.

"There's nothing wrong, that is to say, our friends said they wanted to dance square dance with them, and then we gave the membership fee, plus five yuan for one person."

Zhong Tianzheng asked, "did you have a quarrel?"

"No."

The woman turned her mouth and said, "what's so noisy? The old people just want to live a comfortable life. Five yuan is a small thing, and we can accept it."

Ah Xiang interrupted, "do you know if anyone else has had a dispute with him?"

"I don't know."

Ask here, basically almost.

After all.

If the other party wants to commit a crime, he should not contact the other party before the crime, leaving such an obvious clue to the police.

The investigation at the crime scene has been completed.

The killer didn't leave any clues.

There were no signs of fighting between the two sides. The whole killing process was basically the existence of rolling. The killer did not give the other party any signs of struggle. He directly sealed his throat with a knife, sprinkled money, and then left.

Therefore, we still have to return to the most primitive way.

Mass visits.

Many people said they didn't know what happened last night.

That's not surprising.

Most of the residents in this unit building are the elderly. They sleep early at night, and no one hears any abnormal sound.

Chen chrysanthemum died from more than 10:00 to more than 1:00 last night, but when she was found, it was only when the tenant living on the sixth floor came downstairs the next morning that she found her dead.

As for the residents opposite Chen chrysanthemum, they were not at home that night, so there was no possibility of witnessing.

The community is also such an old community. The internal roads have been fragmented, let alone monitoring.

After the whole visit, Zhong Tianzheng Ah Xiang didn't get any substantive harvest.

Moreover, it is the activity track of the dead Chen chrysanthemum that night.

On the same day, after dinner, Chen chrysanthemum took a small speaker from home and came to victory square one kilometer away to dance square dance. After dancing, she came back.

And what's certain is.

What the security guard said is correct.

Chen chrysanthemum's call records show that the call did come in at 10:15, which is basically consistent with what the old man said at 10:14.

The security guard said that when Chen chrysanthemum entered the community, no one came in with her. As for the follow-up time, no one came in and out of the community.

"Is there any other entrance in the community?"

Zhong Tianzheng glanced at the dilapidated gate and said that since the killer didn't come in through the gate of the community, he either entered the community in advance or came in from other entrances.

"There are other entrances, but they are all closed."

After thinking about the actual report, the old man pointed to the community deployment map on the wall and said, "our community is also a very old community. Although there are three entrances and exits in total, except the gate, this is a fire passage, which is usually closed. Another small door is only open from 7 a.m. to 7 p.m, The rest of the time is locked. "

"Show us."

Led by the security guard, they followed up one after another.

"You two just said you were from the property company. How can you become a policeman now?"

Make complaints about the old man's cigarette in front of him.

"Ha ha."

Zhong Tianzheng smiled awkwardly and said nothing.

"Oh, you young people are really."

The old man didn't care and waved his hand: "in fact, just say it directly. There are dead residents in it. We can't hide it. As security guards, we must cooperate with your police to get things done at the first time. There's nothing to hide. Catching the murderer early is the first thing."

"Thank you for your cooperation."

Zhong Tianzheng bared his teeth and echoed, "your ideological consciousness is still very high."

"I'm kidding. This fine tradition exists in the army."

The old man disagreed: "obey the command, win the war, and adhere to integrity."

In small talk.

The three reached the entrance of the fire passage first.

The gate is very high, and the outside is sealed with iron sheet. Without the key, it is difficult to climb up from the outside, so they just took a simple look, changed the location and came to the second entrance.

This entrance is a left-right push-pull old iron door.

Zhong Tianzheng squinted.

The data given by the devil's eye is one meter eight.

Now the iron gate is open, leaving only one entrance for pedestrians.

Above the iron door.

Several spikes used for anti-theft decoration have been broken.

Go out from this exit and you'll find Guihua Road.

Guihua Road goes down about 500 meters to the big intersection.

"People often climb over this iron door?"

Zhong Tianzheng glanced at the top of the iron door.

The marks of the broken spikes are very old.

"Yes."

The boss sighed: "this entrance is far from the gate. We have to go around a big circle. Some people are too lazy to walk. They will climb over from here and be much closer."

"Yes."

Zhong Tianzheng squinted at all kinds of footprints on the iron door, lit a cigarette and fell into thinking.

In my mind.

The grandmaster's spatial imagination is divergent.

Space and space are quickly formed in my mind.

Victory Square.

Anhua community.

The two sites are united by map.

Digital Zhong Tian is standing at the top of the space, overlooking the two places.

From Victory Square to Anhua community, the straight-line distance is about 800 meters.

According to the information they had, before Chen chrysanthemum died, she danced square dance at the gate of industrial and Commercial Bank of China in Victory Square.

Industrial and Commercial Bank of China.

Chen chrysanthemum packed up her things and went home alone.

Go through midfield Road, Yixin Road, then Guihua Road, and then enter the internal road between the community and directly reach the gate.

This iron door is also her only way.

"Could the killer have followed her on his way home? Then he climbed through the iron gate and came in directly to unit 3? "

Zhong Tianzheng withdrew from the space and made his own judgment.

This may be very possible.

Think of it here.

Zhong Tianzheng felt out his mobile phone and quickly called shixinyu.
