"No wonder we asked all the security guards in the park to no avail, it turned out that he was not a security guard in the forest park." After Wang Xiangrui saw Jiang Yinchun away, he muttered while walking towards the office with his head down.

"If you're not a security guard at the park, why are you wearing a security uniform? Could it be security guards somewhere else? Lin Xuan followed behind Wang Xiangrui, and after hearing his soft muttering, he also muttered.

"Look, I warned you to pay attention to security at the beginning, isn't my hunch accurate?" Ge Bin, who was walking beside Lin Xuan, proudly showed off.

"When did you say that?" Lin Xuan looked disdainful.

"Right then, we watched the video day and night. I'm not saying, 'There are so many people in and out of the park every day that you can't remember your face...... The only thing that can be identified is the security guard'. Ge Bin tried his best to prove it.

"Okay, as long as you kid can do." Lin Xuan teased angrily, "The case of Beijiang Middle School is all up to you, we are waiting for you to solve the case, Detective Ge." ”

"Ah......" Ge Bin screamed miserably and immediately made a plea of mercy.

On the other side, Wang Xiangrui was not disturbed by Lin Xuan and Ge Bin's gags at all, and his thoughts were still on receiving Jiang Yinchun just now. He said to Huang Fangyuan with a little hesitation: "Did you say too much just now, right?" In case we can't catch the murderer, how are you going to explain to Jiang Yinchun? ”

Hearing Wang Xiangrui's words, Lin Xuan also immediately came back to his senses, and followed up and said: "Yes, boss, this case is not investigating us now, and it is not up to us to decide whether the criminal team can solve the case." ”

"Don't worry, I'm sure." Huang Fangyuan glanced at Lin Xuan, patted Wang Xiangrui's shoulder again, and then said to Ge Bin, "The park surveillance video that was burned before is still there, right?" ”

"It's in- but boss, we still have a murder case from Beijiang Middle School here that hasn't been solved!" Ge Bin reminded anxiously, "The fingerprint comparison results came out in the morning, and the murderer may be someone else." ”

"Really?" After thinking for a few seconds, Huang Fangyuan insisted, "I'll just look at the surveillance video from the morning before the crime, and I won't delay much." ”

Everyone present knew Huang Fangyuan's attitude towards work, once this stubbornness came up, ten cows would not be able to pull it back.

Ge Bin obeyed Huang Fangyuan's arrangement, came to his desk, operated the computer, and opened the surveillance video at the park gate that he had saved before. Everyone huddled in front of the computer screen, staring intently. They started at 5 a.m. before the first case and played at twice the speed.

Soon after, a figure wearing a grass-green security uniform appeared on the computer screen.

"Xiaoge, is there a surveillance video from another angle? See if you get a picture of this person's front? ”

Under Huang Fangyuan's instructions, Xiao Ge called up the surveillance video from another angle. Although the quality of the picture was a little blurry, when they saw the man's face, everyone showed an incredible expression.

"Boss, why is he?" Lin Xuan was the first to call out, "Isn't this the security guard from Beijiang Middle School?" On the day of the accident at Bac Giang Middle School, he came to us to report the case. ”

"Why is he there at this point in time?" Ge Bin instantly changed from surprise to excitement, "Could it be that he will become the key clue to solve the case?" ”

"That's a question for him to answer." Wang Xiangrui also showed unprecedented excitement.

"Looks like we're going to have a good talk with the security guard." Huang Fangyuan said calmly.

Among the four people present at the moment, he is the only one who is more restrained.

Huang Fangyuan immediately reported the clues he had to Deputy Director Cui. After obtaining the consent of Captain Xu of the Criminal Investigation Detachment, Deputy Director Cui immediately instructed Huang Fangyuan and the others to go to Beijiang Middle School and summon the security guard to the Shibei Police Station for questioning.

Fifteen minutes later, Huang Fangyuan took Wang Xiangrui, Lin Xuan and Ge Bin to Beijiang Middle School. However, they pounced. The school said that the security guard they were going to summon was named Luo Zhijie, and that he called for sick leave the day after the school reported his death and did not come to work for the past two days.

"Do you have his home address and contact information?" Huang Fangyuan asked a person in charge of the school's security department.

The man immediately took out an address book, turned out Luo Zhijie's contact information and home address, and copied it to Huang Fangyuan.

Huang Fangyuan handed Lin Xuan a note with the suspect's communication information and said to him: "You and Ge Bin go to verify this address first, if there is no problem, you can go to his house now." After a pause, Huang Fangyuan said with a little hesitation, "However, according to my judgment and analysis, there is a good chance that he has already run away, and you may not be able to catch him if you go." If this is the case, your main purpose is to find out from his family where he might be hiding. ”

Lin Xuan received the order, accepted the note, and immediately left with Ge Bin.

After arranging other people's work, Huang Fangyuan asked the person in charge of the security department: "Are your security guards here hired and dispatched by the 'people' security company?" ”

"Yes." The person in charge replied as he handed Huang Fangyuan a cigarette and lit it for him.

"In other words, the security guards hired by Shibei Forest Park and your school are all from the same security company." After Huang Fangyuan took a puff of his cigarette, he asked suspiciously, "Why are the uniforms worn by the security guards of your two units different?" ”

"That's right. The uniforms currently worn by the security guards at our school are old, and they are wearing new uniforms that were issued some time ago. We were originally going to change it here, but the security company said that due to the large number of orders from the manufacturer, it was too late to produce, and we would replace it later. Anyway, it's almost holiday time, and we have little impact on changing early and late here. No, the new uniforms just arrived yesterday. With that, the person in charge pointed to a large cardboard box stacked in the corner.

"How many security guards do you have here?"

"There are five of them."

"How are their leaders arranged?"

"Four of them are shifts - one in the morning and one in the middle of the day off - and the other is Luo Zhijie, considering his special situation, we only arrange him to do the regular shift, that is, from 8 am to 5 pm."

When Huang Fangyuan heard the person in charge say that Luo Zhijie was in a special situation, a flash of light flashed in his eyes. He immediately asked, "What's his special situation?" ”

"He seems to be suffering from a mental illness like depression. I heard that because of this disease, he has been unable to find a job. In addition, I only went to a vocational school and did not have a diploma, so I could only come to us to work as a security guard. ”

"Does he show a manic and irritable side at work?" Huang Fangyuan began to ask targeted questions.

"Not really, on the contrary, he is very introverted and doesn't talk to people much. There is also the fact that he stutters a little when talking to strangers, which may be because he does not communicate with others. ”

"Do you guys think there's something wrong with him lately?"

"No, it's been normal. He usually seems to be very honest and hard-working. I arrive 10 minutes early every morning, and before I leave work, I have to go around every classroom in the school building to make sure all the doors and windows are locked before leaving. "The person in charge told the truth 1510.

"If you have any news of Luo Zhijie, please contact us in time." Huang Fangyuan finished the last puff of cigarette, snuffed out the cigarette butt in the ashtray, and stood up, "Let's stop here today!" I'm sorry that it takes up your valuable working time, but thank you very much for your cooperation. ”

The person in charge also quickly stood up, walked to the door, opened the office door for Huang Fangyuan, and kept muttering softly: "You're polite...... It's serious, it's serious...... Where, where...... The police station is next door, and once we have news of Luo Zhijie here, we will immediately go over and report it. ”

"Please stay, don't send it." Huang Fangyuan politely declined the person in charge's send-off.
