After a night of looking through the case files, Jiang Tingbai and the others searched through the cases that had not been closed for more than 20 years and that the murderer was at large, and compared Liu Yuzhou's biological samples with the case files, and found no matching cases.

The serious crime team also inquired about Liu Yuzhou's mobile phone number, retrieved all his call records in the past month, and after careful investigation, we finally locked down a person.

This person has been on the phone with Liu Yuzhou frequently in the past month, and he is Liu Yuzhou's old acquaintance.

Li Xiaojie, male, 46 years old, a local, has been a friend of Liu Yuzhou for many years, and has opened an art studio in the city, mainly responsible for the art production of web icons and game icons, and the two are not only friends, but also partners.

Li Xiaojie and Liu Yuzhou are friends, and the two have been talking frequently in the past month, and they also talked about retribution in social software. In this way, Li Xiaojie must know what happened to Liu Yuzhou 20 years ago, and he must also know what the so-called retribution means.

"Investigate this person now!" I said immediately.

At this moment, the Ningzhou Municipal Public Security Bureau received an alarm call - Li Xiaojie committed suicide by jumping off the building.

The Serious Crime Team immediately set off and rushed to the scene of the crime.

A long cordon has been set up at the scene, and the crowd of onlookers standing outside the cordon is full, but people in the crowd keep leaving because they can't stand the smell and bloody scenes of the scene.

After receiving the alarm, Li Xiaojie got up at 6 o'clock this morning, walked to the balcony alone, and jumped from the sixth floor......

The serious crime team investigated the scene, investigated the situation from the police and Li Xiaojie's family, and the forensic doctor entered the venue to conduct a preliminary autopsy.

The informants are Li Xiaojie's wife and daughter, and they are also eyewitnesses who witnessed the whole process of Li Xiaojie's jumping off the building.

The mother and daughter were sitting by the flower pond on the side of the road, not yet recovering from the bad news, they sat side by side, holding each other's arms, looking a little dazed, crying like a tearful person. Two female colleagues of the criminal police are comforting them while they do the aftermath.

"Are you Li Xiaojie's family?" I stepped forward and asked softly.

When they saw me coming, they looked at me with tears in their eyes and nodded weakly.

"I'm a criminal police officer from the Ningzhou Public Security Bureau, and I want to investigate something with you." I said lightly.

The two wiped their tears and nodded.

"Who are you who committed suicide by jumping off a building?" I asked.

"It's my husband, Li Xiaojie." The woman swallowed hard and cried.

"When did he jump off the building, and because of what?" I continued.

The woman kept crying, shook her head and said, "When I get up in the morning, at six o'clock, I don't know why......"

I thought about it, looked at them seriously, and asked, "What happened before Li Xiaojie jumped off the building?" ”

He ...... He ...... "The woman choked up and couldn't say a complete sentence."

"Don't worry, take your time." I slowed my voice and said softly.

The woman steadied herself and told me about what had happened this morning: "My husband's cell phone rang around six o'clock this morning......

At six o'clock in the morning, it was already dawn, today is Saturday, the children do not go to school, we do not have to get up early.

At this moment, Li Xiaojie's mobile phone rang, it was a call.

In this day and age, few people can make phone calls, and they generally use social software to connect.

Li Xiaojie slowly opened his eyes and reached out to pick up the mobile phone charging at the bedside.

"Hello? Who is it? Li Xiaojie yawned and answered the phone.

The woman was woken up by the sound of the phone, rubbed her eyes, and asked her husband beside her, "Who?" Calling early in the morning? ”

"Liu Yuzhou's phone should be a matter of work, it's okay, you can sleep again," Li Xiaojie sat up, turned back to his wife and said.

Li Xiaojie walked into the living room while listening to the phone, no one knew what was said on the phone, and Li Xiaojie didn't reply, he kept listening to the other party.

The phone call lasted about five minutes, and Li Xiaojie basically answered without saying anything.

Li Xiaojie stood in the living room for a while, walked straight to the window of the living room, and poked his head out of the window to look out.

In less than a minute, he jumped off......"

After listening to the woman's description, I suddenly frowned and confirmed to her: "You mean, Li Xiaojie answered a phone call, and after the call, he jumped off the building directly?" ”

The woman looked at me and nodded in horror.

"Did Li Xiaojie say anything before jumping off the building?" I asked her.

The woman looked at me in horror and shook her head.

"And what about the recent period? Did he behave abnormally? I took a cool breath and asked.

The woman slowly lowered her head, pondered for a moment, and shook her head slightly.

Li Xiaojie was woken up by a phone call in his sleep, he listened to the person on the phone for about five minutes, and then jumped off the building without saying a word?

It's also weird......

At this moment, the little girl on the side suddenly spoke: "I remember......"

"What do you remember?" I asked hurriedly.

The little girl held her mother's arm tightly and said in a trembling voice: "I have always felt that my father has been a little restless lately, as if he is hiding something in his heart, and he is always frowning and very serious. ”

"Oh? Tell me more. I nodded, giving an affirmative look.

"One time I overheard my dad on the phone, and he seemed to mention some retribution, and I didn't know the specifics, and I didn't ask." The little girl said quietly.

Retribution again? Liu Yuzhou also mentioned retribution before he died.

Liu Yuzhou has communicated frequently with Li Xiaojie in the past month, and they both mentioned retribution, indicating that they must all know about it.

But what are they afraid of? What did they do?

We found Li Xiaojie through Liu Yuzhou's call records, but at this critical moment, Li Xiaojie committed suicide by jumping off the building.

It's not sooner or later, but at this time, and it's a suicide, who called him and what did he say on the phone?

"Do you know who the person who called Li Xiaojie this morning is?" I suddenly asked the woman.

The woman looked at me blankly, recalled it carefully, and said: "It seems that his name is Liu Yuzhou, my husband often mentions him, and they are good friends." ”

"Liu Yuzhou?!" I was stunned.

"It's Liu Yuzhou, he told me when he answered the phone." The woman nodded in confirmation.

Liu Yuzhou is dead! How can you call?!

Someone pretended to be Liu Yuzhou's identity and called Li Xiaojie? What did he say on the phone that would make Li Xiaojie give up his life and resolutely jump off the building?

"Take their mother and daughter back to the police station to make a record, and you have to do it in detail." I said to my fellow detectives.

A phone call can ask for someone's name, this person is not simple.

Picking up the cordon, Ren Qiushi and Zeng Lan were doing autopsy work at the scene.

"How?" I asked.

"It was a high fall, and he died on the spot."
