"Why are you leaving in such a hurry? You haven't even finished asking yet."
Mu Wen looked at Luo Qianran. If he continued to ask, he would definitely ask about other things.
"He has already told us everything he knows. There is no need to ask any more questions."
Luo Qianran was very confused. There must be someone they left behind in the whole case, and this person was the most critical person.
Mu Wen was somewhat confused and asked them to keep investigating what they were investigating.
"Go back to the station first. I have to see the body again."
Luo Qianran frowned, this matter was not that simple.
In the cool autopsy room, Luo Qianran looked at the autopsy reports in his hands. The autopsy reports on the three corpses were exactly the same as those of Shu Yue many years ago.
"The same cause of death, the same death by falling from a building, the same location, why did the murderer do this? How many secrets are hidden in that letter from heaven?"
Luo Qianran frowned and slowly closed his eyes, as if he thought of something. The next second, he opened his eyes, and there was a person who they had always missed.
In the hall, people were coming and going, and everyone was busy with the work at hand.
"In that case, the principal has nothing to do with this matter. He just concealed the fact that Su Mei is his illegitimate daughter."
Tao Su looked at the confession and played with the pen in his hand. Now the whole case has fallen into a dead end again.
"Tell me, if they did not commit suicide, who would be the most likely murderer in this case?"
Mu Wen was puzzled. They had investigated everyone involved in this case, but found nothing.
While the two were chatting, Luo Qianran came down the stairs with a very serious expression.
"There is another person we have never investigated."
Luo Qianran walked towards the two of them and said this when he walked in front of them.
"who?"
Mu Wen and Tao Su asked in unison.
"Shu Yue's mother."
Luo Qianran solved the current mystery with one word, and Mu Wen immediately realized that the person they had been ignoring was Shu Yue's mother.
Mu Wen put his hands on the keyboard and typed quickly, and soon a survey result came out.
"After Shu Yue's mother remarried, her husband was a doctor, a doctor in a private hospital. After investigation, he went to the larval hospital and took psychiatric drugs home."
The more Mu Wen talked, the more excited he became. This must be the key to solving the case.
"Check, continue to investigate. If the three deceased people took psychotropic drugs, then I will definitely be able to find such things in their bodies. However, the autopsy found that there were no drugs at all. The investigation must continue. .”
For Luo Qianran, this was a breakthrough. As long as he found out what kind of drug it was, he could find someone with the evidence.
"I'm going to do some research on psychotropic drugs right now."
Tao Su stood up from his position and quickly left the police station.
Mu Wen continued to investigate everything about Shu Yue's mother.
Soon, Tao Su came back from the hospital and brought back a kind of medicine that Luo Qianran had never seen before.
Luo Qianran looked at the medicine bottles in the bag. He couldn't wait any longer and wanted to get closer to the truth immediately.
The doorbell of the villa rang, and the person who opened the door was Shu Yue's mother.
"Who are you looking for?"
Shu Yue's mother is very similar to Shu Yue. Luo Qianran and Mu Wen's eyes met, which further confirmed his suspicion.
"We are from the task force and we have some questions we would like to ask you."
Mu Wen took out his work certificate and said.
The woman's face darkened, but it was fleeting, and she warmly invited the two of them into the living room.
Two cups of tea were placed in front of the table.
The woman sat down on the sofa and looked at Luo Qianran in front of her. She seemed not surprised by their arrival.
"I heard that your husband is a doctor in a private hospital. We would like to ask him to take a look at it. Does he recognize this thing?"
Mu Wen took out a medicine bottle from his pocket and placed it on the table.
Luo Qianran was still observing the woman's expression, trying to find something suspicious in her expression.
"Sorry, my husband has been on a business trip recently. I think you should ask the people at the hospital. Maybe they know more."
The woman's expression was very calm, and she answered their questions in an orderly manner, seemingly without any problems at all.
Mu Wen also didn't expect that the woman would answer his question so cleverly.
The woman's words made Mu Wen don't know how to continue asking.
"Excuse me, we have some things to do, so we'll leave first."
Luo Qianran understood that even if he continued to ask, he wouldn't be able to get anything out of it, so he stood up first.
"Then you two walk slowly."
The woman also stood up and walked the two of them to the door.
"It's strange, why is she so calm?"
Mu Wen was a little confused. Logically speaking, she should be familiar with this kind of thing.
"Let's continue to investigate. She won't speak without enough evidence."
Luo Qianran sat in the passenger seat, and he could feel that Shu Yue's mother was not that simple.
Night falls.
The campus was extremely quiet, the wind was strong, but it was extremely dark.
In the dark night, a woman slowly climbed up the stairs to the top floor. She turned around and looked behind her. She smiled. When she turned around, she jumped.
Police station.
Luo Qianran suddenly woke up from his dream, with cold sweat already covering his forehead. Looking at the autopsy report on the table, the dream just now was very real.
"Luo Qianran, someone committed suicide by jumping off the building again. Follow me to the scene."
Mu Wen's urgent voice rang in his ears. Luo Qianran frowned and immediately rushed to the scene together.
The same location, the same way of jumping off the building, the police have already set up a cordon.
The body had been covered with a layer of white cloth and was being transported to the police station.
"You are here. The death this time will definitely surprise you."
Seeing the two men coming in a hurry, Tao Su pulled apart part of the white cloth on the body so that the face of the deceased could be seen.
When Luo Qianran looked at the person in front of him, his pupils suddenly widened, and Mu Wen felt even more incredible.
"Shu Yue's mother?"
Mu Wen couldn't believe that the meeting in the afternoon was fine.
"This is a letter she left behind, holding it tightly in her hand."
Tao Su took a letter and handed it to the two of them. The envelope was already stained with blood.
In the lobby on the first floor, Luo Qianran looked at the envelope in his hand, which contained detailed records of how he tricked three girls onto the rooftop and dressed each of them up to look like Shu Yue. She was A mother, her own daughter suffered such a tragic experience. As a mother, it is absolutely impossible to let it go. She only thought of this method later. However, it took so many years before she finally completed her revenge. It was just an envelope. But there was no mention of the invitation letter from heaven.
