Dabin, who was halfway through speaking, suddenly stopped, turned around, looked at Huang Fangyuan, who was sitting behind him on the right, and asked him directly: "Sheriff Huang, I remember that you said that the morning before yesterday, that is, on the day of the crime, Xu Zhonghui came to you to report the case because he questioned that his wife's accidental death was a man-made accident, is that the case?" ”

"That's right." Huang Fangyuan replied calmly.

"After that, you and Lao Wang immediately went to visit the old house of the An family, right?"

Seeing Da Bin vigorously asking Huang Fangyuan about an unnatural death accident that had little to do with this case, everyone showed an unknown look, and their curious eyes roamed back and forth between the two.

"Yes."

"When did you go to settle down at the old house? Was Xu Zhonghui at home at the time? How long have you been in the old home? Can you give us a brief description of the situation? ”

"Lao Wang and I arrived at the Anjia old house at about half past ten according to the agreed time in advance. When we arrived, Xu Zhonghui was already waiting at home. We briefly asked him a few questions, mainly about the people who came and went to the old house after the accident, and whether there were any other suspicious incidents. After that, we carefully inspected the leaking liquefied gas tank and the general situation in the room, and used the forensic instrument to take pictures and collect evidence, which took a total of about half an hour. When Lao Wang and I left An's old house and returned to the police station, it was close to half past eleven o'clock in the afternoon. Huang Fangyuan summarized the situation of the day in the most concise language.

"Dabin, why are you asking Sheriff Huang about this?" Deputy Director Xiao asked the questions in the hearts of most of the people present in a surprised tone.

"I just want to confirm whether Sheriff Huang and the others bumped into the scene where Xu Zhonghui and the nanny were on the phone." Dabin sat up again, facing the leadership platform in front of him, raised his perspective slightly, and explained to Deputy Director Xiao, "Because when we checked Xu Zhonghui's mobile phone communication this morning, we found that he had made a phone call to the deceased at 11:35 p.m. that day. I don't know if you remember that after the nanny was killed, we checked her mobile phone communication records, and there were no call records of the two of them. Dabin's gaze swept over the faces of the leaders present in front of him one by one, "In other words, the communication records in the nanny's mobile phone have been artificially deleted." Also this morning, when Captain Xu was investigating Xu Zhonghui's hotel accommodation registration information, he found that Xu Zhonghui and the nanny had opened the room five times in the past three months. After combining these two clues, we came to the conclusion that there was some kind of improper relationship between the two, and the call records in the mobile phone were probably deleted by the nanny......"

"There's another possibility."

A calm male voice came from a corner of the conference room, interrupting Dabin's speech. Everyone followed the prestige, and the person who spoke was Huang Fangyuan.

"If we look at her relationship with Xu Zhonghui from the standpoint of the nanny, we will find that she does not have the absolute need to delete the call history. She does need to guard against outsiders snooping on her true relationship with Xu Zhonghui, but she doesn't need to guard herself. The mobile phone is her personal belongings, and outsiders can't easily snoop on her privacy. And now that we already know that she and Pan Zilong are not husband and wife, she doesn't have to be wary of him conducting surprise inspections, and deliberately deleting communication records is redundant. Moreover, the two already have an employment relationship, and it is not uncommon for them to call and exchange some housework on weekdays, even if they are inadvertently snooped on by outsiders, they can be covered up. ”

"What is your conclusion?" When Captain Liao opened his mouth to ask, he seemed to have vaguely guessed the answer.

"I remember that when the comrades of the Criminal Division were inspecting the scene of the nanny's murder, they pointed out that there were traces of human cleaning at the scene of the crime, and the surface of the furniture had been carefully wiped, so that they could not collect any valid fingerprints, including the victim. Obviously, the murderer did not want to reveal his identity and deliberately erased the traces of his visit to the scene of the crime. In the same way, since he had time to clean up the scene, it is not ruled out that he cleaned up the deceased's mobile phone, from which he deliberately erased the content that might expose him. ”

"There is some truth to the analysis." Captain Liao agreed.

"If you go on, what else have you found?" Deputy Director Xiao ordered at Dabin.

At around 11:35, after he finished talking to his nanny on the phone, he called Pan Zilong's phone, and the call between the two lasted nearly ten minutes. It wasn't until about 1:05 p.m. that the two had a second call. There was no other correspondence until around 6 p.m., when he had a brief phone call with An Ran's cousin, Anxin. According to the results of Ge Bin's investigation, the two met at the 'Angel' bar on Xuexue Road that night, and we guessed that the phone call should be related to this. We verified the coordinates and locations of Xu Zhonghui when he made these four calls, the first three were on Hongxia Road, and the last one was near Xuezi Road, all within Jiangbei District. Since then, there has been no communication record on his mobile phone. Dabin paused for a moment, and then concluded, "Therefore, it is impossible to reflect his movements throughout the day from the communication records alone, let alone analyze and judge his possible whereabouts after the incident." ”

As Da Bin's speech ended, the conference room fell silent.

In the middle of the night, Deputy Director Xiao coughed lightly, breaking the embarrassing atmosphere in the venue.

"In addition to the work led by the Criminal Investigation Corps, in order to verify the time of Xu Zhonghui's crime, the Suburban East Branch also went to retrieve the surveillance video of the community where the Anjia villa is located last night, let's ask Captain Tao to introduce the relevant situation......

Before Deputy Director Xiao could finish speaking, the door of the conference room was pushed open, and Captain Qi appeared at the door of the conference room. His appearance instantly attracted everyone's attention, and even Deputy Director Xiao said directly: "You guys came back too timely, I heard that you have gained a lot, quickly report to you what you have found." ”

Captain Qi walked with vigorous steps to the position where the laptop was placed on the side of the leadership desk. The morning of running back and forth, coupled with the overtime work in the past few days, not only did not make him show a trace of fatigue, but because of the key clues he obtained, he exuded a dazzling brilliance around him.

When everyone saw him so full of ambition, they knew that he must have gained something from this trip, and there was still a drama in this case.

Captain Qi stood still in front of the place where the laptop was placed, took out a disc from his pocket, and explained while opening the laptop's optical drive: "I have downloaded all the data back, but due to time constraints, I haven't had time to export it for further combing and analysis. The contents of this CD-ROM were slightly sorted out by Tencent's technical staff and engraved into a CD-ROM for everyone to see. ”

Captain Qi hunched over and operated on his laptop for a while. When the director of the Shibei Police Station, who was sitting in the audience, saw this, he immediately turned his head to look at Lin Xuan behind him. Lin Xuan understood, immediately got up, picked a chair in the empty seat in the back row, and moved straight to Captain Qi's side. Captain Qi nodded in thanks, adjusted the distance between the seat and the table slightly, and then went down. During this time, his eyes were always fixed on the computer screen in front of him.

In an instant, on the huge projection screen on the leader's stage, the original background picture has disappeared, replaced by a set of charts. Captain Qi used a mouse arrow instead of a laser pointer to direct everyone's attention to what he was going to explain.
