The forensic wife is very nice to me

In the monitoring room of the police station, the controller on the doorknob scanned Xu Chengyan's fingerprints and opened the door after confirming his identity.

Walking into the room, there are dozens of monitors neatly arranged inside. Each portrait controls each key location of the police station, especially the underground parking lot with the most monitoring.

"Who are you?" The management staff in the monitoring room heard the noise here, strode over, frowned, and looked at the two people at the door suspiciously.

"Hello, I'm the leader of the serious crime team, Xu Chengyan. The person next to me is the forensic doctor of the forensic team, Qiu Lan." Xu Chengyan took out the police ID card in his bag and showed it to the management staff, confirming himself and Qiu Lan's identity.

"Officer Xu, Doctor Qiu, hello, I'm the person in charge of the monitoring room." After checking the police ID, the manager frowned slightly and asked softly, "It's so late today, I don't know you What's the matter here?"

Xu Chengyan looked at the monitor screen behind him with a dignified expression, and his lips were drawn into a straight line, "Dr. Qiu heard strange footsteps in the underground parking lot just now. I suspect it has something to do with the person who threatened her before. All come here have a look."

"Have you been guarding the surveillance here?" He glanced at the person sitting in front of the video portrait looking at the screen, and said slowly.

Hearing his words, the administrator nodded slightly, "Yes, this is the monitoring and control center of the entire police station, so we are guarded here 24 hours a day, weekends are no exception."

"Then did you see anything unusual about the underground parking lot in the video just now?" Qiu Lan bit her red lips lightly, raised her eyebrows uneasily, and spoke hastily.

"Parking lot?" The management staff lowered their eyes and thought about it for a moment, "I don't have any impression of this, but there should be nothing unusual, otherwise our people will definitely go down to check."

"That's it." Xu Chengyan frowned indifferently, and glanced worriedly at the person beside him, "Then can I trouble you to show us the surveillance video from 10 minutes to 10 minutes ago?"

In the toilet of the autopsy room, Qiu Lan had already been threatened once, but that time, she did not find any directional clues.But unexpectedly, she heard sneaky footsteps in the parking lot today.

No matter what the sound is, Xu Chengyan will investigate clearly and will not let go of any clue.

Since this person can haunt the police station, every time he intimidates Qiu Lan, if he doesn't find out as soon as possible, maybe there will be greater danger hidden in the future.

"Okay, Officer Xu, Doctor Qiu, come with me." The person in charge of the monitoring room replied, leading them into a small office behind the huge monitoring system.

He turned on a computer on his desk, entered some information into the computer, and finally found some of the programs, "These are the monitoring of the entire parking lot from Area A to Area E."

"Because the underground parking lot is an important location and it is very large. It is divided into five areas in total, and there are about [-] surveillance cameras. It may take a lot of time to look at them one by one." The management staff moved their lips lightly and crossed their hands On the chest, simply told them the information here.

"I heard the sound in Area C, near the No. [-] elevator of the police station." Qiu Lan twirled her fingers, recalling the situation just now, "The sound was very close to me."

"It's about 15 decibels. According to the distance calculation, with me as the center point, it should be at a distance of ten meters to [-] meters."

Listening to her words, the manager nodded, his eyes fluttered, he turned around and clicked on two video images on the screen, "Doctor Qiu, according to your words, I think the surveillance cameras of C3 and C5 should be able to capture some content .”

"This computer is connected to the monitoring system. You can watch the real-time situation or play it backwards." The manager moved the mouse, dragged the progress bar below, and moved to the first three 10 minutes.

After pressing double fast forward, all three people in the office stared intently at the images on the computer screen.

After about 2 minutes, a woman's figure appeared in an area in the lower right corner.

"It's just me." Qiu Lan pursed her red lips and looked at the situation carefully, "Looking at my appearance at that time, I probably haven't heard anything yet."

After seeing Qiu Lan's figure appearing in the surveillance video, the management personnel switched the double speed to [-] times, so that it was easier to see the two surveillance images clearly.

"You turned around, you should have heard the sound." Xu Chengyan looked at every corner of the surveillance seriously, and the expression on his face gradually froze, "But, we can't see anyone else here."

"Yes, I didn't see it when I turned around." Qiu Lan looked at the computer screen with a serious expression, frowning slightly, "However, it should have been less than a minute before I heard the voice behind me again."

Sure enough, in the surveillance video at 46x speed, [-] seconds later, Qiu Lan turned around vigilantly in the image, and the expression on her face became even colder.

The next thing was her defense against the wall, and then Xu Chengyan appeared.

During this period of time, she didn't hear any sound, maybe because of the appearance of other people, the person who made the sound left, or maybe she didn't come to pay attention.

In the office of the monitoring room, Xu Chengyan and Qiu Lan looked at each other solemnly.

"Officer Xu, Doctor Qiu, this is the surveillance video for this period of time, but there seems to be no one else showing up except you." The management staff pressed the pause button, turned to look at them, and spoke slowly.

"Yes, but the voice appeared twice, why can't we see the figure?" Qiu Lan sighed softly, staring at the computer screen meaningfully.

"Doctor Qiu, do you think there is a high possibility of hearing it wrong?" Xu Chengyan pursed his thin lips, and asked softly, "Recently, you have had one case after another, and you must be very tired. Could it be an auditory hallucination?"

Before Qiu Lan joined the forensic team, he had investigated a suicide case. In that case, a witness kept saying that he heard voices calling for help at the scene of the crime.

But in the end, after confirmation by the forensics department and the accurate judgment of the forensic team, it was found that the witness was overworked, which caused temporary damage to some functional parts of the brain, resulting in auditory hallucinations.

In the case at that time, other evidence pointed to the suicide of the deceased, but because of a hallucinatory statement by this witness, the entire serious crime team investigated for a whole month without any results.

So Xu Chengyan always remembered to ask for this case.

"No." Qiu Lan shook her head, her eyes fixed on the surveillance screen, "Officer Xu, although there have been many things going on recently, I have ensured a good sleep, so I shouldn't have auditory hallucinations."

"What's more, how could I have auditory hallucinations twice in such a short period of time? The chances of this are extremely slim."
