Fang Hao emphasized over and over again that he really didn't know Du Keke, and he didn't know what Du Keke's purpose was in calling and texting him at that time.

After the inquiry, Li Fangfang looked at the silent crowd and proposed: "Why don't you ask a polygraph expert from the provincial department tomorrow to test whether he is telling the truth?"

Xiao Ran shook his head, from Fang Hao's tone and demeanor, he could roughly determine that what Fang Hao said should be true.

As for why Du Keke called Fang Hao to send a message, it is likely that this is also a smoke bomb deliberately created by someone, and he dialed out casually after finding a number, trying to confuse the police's attention, but he didn't expect to dial Fang Hao's number by chance.

But is there really such a coincidence? I found a mobile phone number, but not only did I not leave the province, but I didn't even leave the city.

Xiao Ran doesn't believe in coincidences, and many times, coincidences don't appear for no reason. But if there was really a person who took Du Keke's mobile phone to call Fang Hao, did this person have any contact with Fang Hao again?

And Fang Hao heard a female voice coughing on the phone, which was probably Du Keke's voice, obviously Du Keke's life was unharmed at that time.

But during the dozens of seconds of the call between Du Keke's mobile phone and Fang Hao, if Du Keke's life was already in danger at that time, why didn't Du Keke say a word at that time?

Is this some of Du Keke's profound actions, or is the person who was holding Du Keke's mobile phone at the time considered by Du Keke to be absolutely trustworthy, so he didn't take precautions, and was killed after calling Fang Hao?

All of this is like a mess that has been ravaged for a long time, and every thread of rope in it carries an incomprehensible mystery.

"No more polygraphs, let it go. Let him find someone to come and take him back. Xiao Ran thought for a while and said, he grabbed his hair and looked up at the deep sky.

It's a little dark today.

In the early hours of the morning, a friend of Fang Hao rode a domestically made ** motorcycle to the criminal police brigade, watching Fang Hao take the helmet and put it on, Qin Zihe, who watched the two get into the car, couldn't help but ask: "What about your A7, why didn't you see it?"

"That's not my car. Fang Haomai got on the motorcycle, waved his hand back, and left another sentence before leaving: "...... I may not be able to drive that car in the future. ”

- Maybe Fang Hao himself knows that after Xiao Ran and their investigation, the relationship between him and the female boss is basically about to be severed.

After Fang Hao left, Xiao Ran and the others returned to the office, and everyone looked at the desktop silently, thinking about where to start next.

The contacts in the address book of the deceased Du Keke's mobile phone were basically asked, there were suspicious men, half of them had been found, and the DNA was compared with the DNA on the embryo, although the suicide note knew that it was forged, but I didn't know who wrote it.

There were no suspicious traces of the crime left at the scene, and the characteristics of Du Keke's body were completely consistent with the voluntary hanging, and the woman who took the money from her bank card disappeared as if she had entered the sea.

For a while, no one knew where to go to investigate.

And because Du Keke meets the characteristics of voluntary hanging, the nature of his homicide cannot be determined, so no one knows how long this 'Du Keke theft case' can be investigated.

Xiao Ran looked at the dark sky outside the window, he was not anxious in his heart, always maintain a normal heart in case of trouble, it is the criterion he has always adhered to, as a criminal policeman, he must always remain rational and calm, and not panic.

Xiao Ran went through all the information about Du Keco again in his mind.

Suddenly, he opened his eyes, sat up and said to Zhang Lei: "Leizi, the information of the person who belongs to the mobile phone number in Du Keke's mobile phone address book, as well as the contact information in her social software, have you sorted it out?"

"The information of the person who belongs to the mobile phone number in the address book has been sorted out, and the friends in the social software have only been sorted out. Zhang Lei said.

Xiao Ran nodded, looking at Li Fangfang, Zhang Lei, Qin Zihe and the others: "I still think that Du Keke's death was a perfect murder, what do you think?"

Li Fangfang nodded in agreement: "Although the characteristics of Du Keke's corpse echo suicide, but from all aspects of the information, there is indeed something wrong with her death. We should continue to investigate, and even if it is found out that Du Keke really committed suicide, then we have to find out what she experienced at that time. ”

"Yes, there is a lot of fog right now, and we can't just be so muddy. Zhang Lei and others also agreed.

"Yes, we can't cry for a long time and don't know who died. ”

Xiao Ran nodded and said, "Leizi, bring over the information you organized, we were short of time before, so we just went through it roughly." Now that we don't know where to check, let's go through these contacts in Du Keco's phone one by one, and carefully investigate what everyone in them has experienced. ”

"Okay, I'll go get it. Zhang Lei answered, got up and walked out of the office.

......

Time passed minute by minute, and before I knew it, it was early the next morning, it was already 5 o'clock in the morning on the 15th, it was still dark, and it had been nearly a week since Du Coco committed suicide on the 9th.

Xiao Ran returned to the office with a few breakfasts and distributed them to Li Fangfang, Zhang Lei and others, who had almost never slept all night.

He picked up a list on the table that he had compiled overnight, and it was full of some girlfriends who had been close to Du Keke in the past, several of whom had been administratively detained by the police station a year ago for selling guns, when Du Keke and they worked in the same entertainment venue.

Xiao Ran was going to take Li Fang and release them, and went to find these people one by one to talk in detail: "Everyone hurry up and eat something, and then hurry up to catch up on a few hours of sleep, and then we will set off." ”

"Okay. ”

Li Fangfang and the others said in a loud voice, quickly ate breakfast, and then ran to the lounge, and fell asleep in a blink of an eye.

At 9 o'clock in the morning, Xiao Ran woke up Li Fangfang and others on time, and then Xiao Ran and He Liang were in a group, Qin Zihe and Liu Qing were in a group, Li Fangfang and Song Zhiyi were in a group, and the three groups of people acted separately and began to conduct detailed visits to some of Du Keke's previous girlfriends.

At noon, Xiao Ran drove He Liang to a real estate agency store and found Du Keke's former best friend 'Xiong Banbai'.

This Xiong Banbai was one of the few people who were punished at that time, she used to be a kindergarten teacher, but it was during the day, and at night she worked with Du Keke and others to sell alcohol and do some leather business.

After the incident, Xiong Banbai was disqualified from educating children, and then no one knows what occupations she has done, but now she is an intermediary.

It seems that she has already changed her mind and become a new person!
