After Yan Boxuan looked at it, he took a picture of the small window sill.
Yu Liping's body had been removed by the police, and was about to be sent to the Forensic Medicine Department for further examination, so Gu Shiya went back first.
There is nothing special in the utility room, except for some cleaning supplies, there are some tools such as mops, buckets, rags, etc., but things are a bit messy.
Yan Boxuan looked at Sun Fugui and asked, "Has the utility room always been this messy?"
"No, it's usually very tidy." Sun Fugui paused and said, "We tidy it up every day. Even if it's messy sometimes, it won't be this messy."
Yan Boxuan nodded, trying to find clues where the body fell, he moved the mop next to him, but found a key behind the mop.
He stretched out his gloved hand, bent down and picked up the key, put it in a small bag specially for evidence, and showed the bag to Sun Fugui, Zhao Hong and Zhou Dashan: "Do you know this key? ?¡±
"Well, this key is the key to this door." Zhou Dashan said, "Sister Yu has always held the key in my group."
Yan Baixuan thought of something, turned his head to look at Sun Fugui and Zhao Hong and asked: "Then you are a group with the same key?"
"No, just this one key." Zhao Hong pointed to a row of hooks on the wall by the door, and said, "Usually, the morning shift comes, and the key is hung on it after opening the door, and then when the evening shift leaves , lock the door, and those who worked the night shift the previous day will go to the morning shift the next day."
"That is to say, this key is used alternately between the two shifts?" Yan Boxuan asked.
"Well." Zhang Qiang continued on the side, "Although it's just a utility room, it belongs to the company after all. If there are too many, it will always cause some unnecessary troubles."
Yan Boxuan knew what he meant, and he must have lost a lot of things before, so he came up with this method.
"Okay, basically there is nothing wrong, but if there is something wrong, I may contact you again." Yan Boxuan looked at the three cleaning staff and said, "If you think of anything, you can also call me."
After finishing speaking, Yan Boxuan gave the office phone numbers to three people.
After writing down the phone number, the three looked at Zhang Qiang.
Zhang Qiang then assigned them to other floors.
After the three left, Yan Boxuan looked at Zhang Qiang and asked, "How many utility rooms like this are there?"
"There are six in total, and one such utility room will be specially built every five floors." Zhang Qiang paused and said, "Generally, other buildings have public toilets, and the cleaning staff can put cleaning tools in the public toilets, but Our office rooms all have independent bathrooms, and only the lobby on the first floor has a public bathroom, so we can only build a few such utility rooms separately."
Yan Boxuan immediately asked: "Apart from this key, is there any other key in other people's hands?"
"No more." Zhang Qiang looked at Yan Boxuan and said, "It's like this. The cleaners who come to work here all sign a contract. If the tools are lost, the cleaners will pay for it themselves, so except for them, everyone else No keys."
Yan Boxuan nodded, and then let Zhang Qiang leave as well. He checked the scene carefully again by himself, and returned to the police station without finding any new clues.
When she came back, Gu Shiya just came out of the office, and Yan Boxuan looked at her with a tired face.
"What? Didn't find any clues?" Gu Shiya looked at him and asked.
Yan Boxuan waved his hand, signaling to go to his office.
As soon as he entered the office, Yan Boxuan sat down on the sofa weakly, looked at Gu Shiya and said, "The secret room, the key was found on the ground at the scene of the crime, and this is the only key. Of course, it cannot be ruled out that someone secretly assigned the key." .¡±
"Cutting off the tongue should be a vendetta?" Gu Shiya continued, "It's not necessary to cut off the tongue for that kind of accidental killing or ordinary killing, right?"
"Let's go, go to the archives and look at the case from that year." Yan Boxuan stood up, and went to the archives with Gu Shiya again.
When he arrived, Gao Jiayang was taken aback for a moment: "Could you be here to investigate that case?"
"How do you know?" Yan Boxuan looked at him and asked.
Gao Jiayang raised his eyebrows and motioned Yan Baixuan to look inside. Gu Shiya also followed Gao Jiayang's line of sight and found Cheng Jiajia flipping through the files inside.
"Understood." Yan Baixuan and Gu Shiya walked in, and Cheng Jiajia heard the voice raised.At that time, the alarm phone rang, and someone reported that two dead bodies were found in the village.
At that time, it was rare to see two corpses. Of course, the director attached great importance to it, so he immediately took people to the place where the corpses were found. When the director talks about this matter now, his face is full of sadness. expression.
Gu Shiya and Yan Boxuan listened quietly.
When the director arrived at the scene, two middle-aged women were crying loudly. The director has never forgotten the heart-piercing sound.
The deceased were two sixteen-year-old children, both teenagers and girls in their prime, but they died tragically near their own village, and their tongues were cut off. There was a lot of blood on the loess path, because the whole scene was so tragic. The director hurriedly began to conduct on-site inspections.
After the forensic autopsy, it was confirmed that the two deceased died of suffocation, that is, they were strangled to death. The tongue was cut off after death, and the time of death of the two children was almost the same, so the director suspected that two people committed the crime. If it is one person, it is impossible for one person to strangle two people to death.
When hearing this, Yan Baixuan and Gu Shiya looked at each other. The deceased Yu Liping was also strangled to death, and the technique was almost the same.
The director confirmed the identities of the two children, one named Jiang Zhi and the other named Cui Jia, but what the director did not expect was that not long after they arrived at the scene, when the evidence had not been fully preserved, it suddenly rained heavily from the sky, killing everything. It was washed cleanly, and after the heavy rain, the original big pool of blood disappeared completely. (Remember the site URL: www.hlnovel.com
