"Now there is surveillance everywhere, and we still need to learn this." Ji Si'an wanted to stop this topic.

"Even so, it's still useful. For example, in remote places or when the camera angle is not good, we still need to draw the suspect according to the description of the victim. Yuan Mu said.

Ji Si'an was afraid that continuing to talk would cause discomfort to Yuan Mu, so he changed the topic and said, "Did you come to me today for something?" ”

"You're a friend, I can't come to see you." Yuan Mu said angrily.

Ji Si'an smiled, although Yuan Mu looked outgoing and tough, he was actually a very closed person. With her understanding of Yuan Mu, she must have something to do when she came to find herself today.

Sure enough, Yuan Mu took out a large book from his bag and handed it to Ji Si'an.

"What is this?" Ji Si'an asked like this, and he already had a rough guess in his heart.

"It's ...... The key to the case. I wrote it down while looking through the archives. Yuan Mu said.

Ji Si'an took the somewhat hot notebook and couldn't wait to flip through it.

At 7:50 a.m. on July 1, 2000, the waiter at the Yinglai Hotel at No. 8 Chenghuang West Street called 110 to report that someone had died in room 506.

When the police arrived at the scene, they found two deceased, an adult woman in her 30s and a young child aged 7-8. Another toddler, about 3 years old, suffered a head injury and was taken to the hospital for emergency treatment.

Ji Si touched the portrait on the notebook, and Yuan Mu copied all the photos of the scene.

My sister was lying on a double bed, covered with a thin sheet, her clothes were complete, and even her hair was neatly combed, as ......if she was asleep.

"How did she die?" Ji Si'an didn't control it, tears fell on the notebook with a snap, and she took out a tissue to wipe her face in a panic.

"Mechanical asphyxia...... The medical examiner found cotton fibers in her nostrils, which were examined to come from a hotel pillow. Yuan Mu said.

Compared to her sister, the scene of her mother's death was chaotic. She was lying on the ground, her hair disheveled, and there was a lot of blood on her back.

"She was stabbed three times, all of them in the back, and the murder weapon was a single-edged sharp weapon about 15cm long and 3cm wide. The murder weapon caused ....... ”

"That's enough, this ...... Needless to say, it doesn't have much to do with our investigation of the case. Ji Si'an interrupted Yuan Mu's words.

"Then let's look directly at the on-site investigation and the suspect." Yuan Mu can understand Ji Si'an's mood very well.

Due to the fact that the scene of the crime was a hotel, the number of people coming and going was relatively complicated, and the follow-up protection of the scene was unfavorable, the on-site investigation failed to extract effective evidence. They could only infer from the situation of the door lock that the suspect had entered the room peacefully.

"Although it is said that it is peaceful to enter the room, there will be two situations: one is that the other party knows your mother, and she takes the initiative to open the door for the murderer; The second is that he stole the room card to enter. You also know that the hotel management at that time was chaotic, and there were often cases of getting the wrong room card and losing the room card. ”

"And on the day of the incident, the hotel's surveillance was broken and it was being repaired...... All kinds of coincidental factors are superimposed to cause this case to be solved for a long time. ”

Ji Si'an didn't seem to have heard of it, after so many years, she no longer had the patience to listen to those meaningless explanations and analyses. She flipped straight to the back to see the suspects they had targeted.

First the acquaintances of the father and mother were excluded, then the waiter of the hotel was excluded, and then the ex-convicts near the hotel, and even the outrage criminals were all taken into account. Ji Si'an sat down in his chair gloomily. The police are much better at handling cases than her half-, they have thought of everything she can think of, and even what she can't think of, they have thought of .......

"There is also an analysis of the suspect's behavior by criminal investigation experts in the back. Look...... Maybe it helps. Yuan Mu said.

The suspect was a male, between 30 and 40 years old, with a strong body, and judging by the fact that he was able to successfully get the victim to open the door, he should be an easy person to gain the trust of women. or outstanding in appearance, or elegant in conversation. Of course, this is an analysis based on the exclusion of acquaintances.

The suspect is full of guilt for the girl's death, but full of resentment towards the woman, if an acquaintance committed the crime, he should have a conflict with the woman; If the crime is random, he may be in a period of emotional turmoil.

Judging from the treatment of his sister, he killed his sister but only knocked her unconscious. He obviously deliberately let his sister go, perhaps because his sister was too young to identify him, or maybe he was moved by compassion .......

These analyses were too general to help her, and Ji Si'an closed the notebook and tried to calm herself down and think. "They still doubted their father?"

"There was no property loss at the scene, and if the crime of embezzlement of property is excluded, the first thing to consider in this kind of case is the spouse." Yuan Mu tried his best to make his voice sound natural. "But don't worry, your father has an alibi, he wasn't in Chenghuang at the time."

"He didn't ...... in Chenghuang, so how could he rest assured that his mother would take me and my sister out alone." Ji Si'an said in a reproachful tone.

"He said in the transcript that your mother brought you to Chenghuang to attend the class reunion, and he planned to stay for two days and then go back, but the accident happened on ......the day the class reunion ended." Yuan Mu said.

How does it sound weird to bring your children to a class reunion ....... Ji Si'an didn't know what to say for a while.

"Your father said that your mother was in a bad mood during that time, and they had a fight. She insisted on taking her children to the party, which may also mean to distract herself. ”

"And all the classmates who attended the party that night, we also checked, and found no problems."

It's a cold case, and I really don't have a clue at all. Ji Si'an scratched his hair and was extremely frustrated.

Yuan Mu understood her feelings. "Thousands of police officers were mobilized to conduct large-scale investigations, but there were no results. We have to be patient ....... ”

"Something must have gone wrong, I'll have to think about it." Ji Si'an grabbed the notebook and said.

"Let's start with the people who were convicted of being suspects at the time." Yuan Mu put forward his own ideas.

She listed the names of the suspects one by one and wrote the reasons for the exclusion at the back. Ji Hui and Li Shanlan made an alibi for .......

Ji Si'an looked at these two somewhat unfamiliar names, and his nose was slightly sour. If she hadn't dealt with her grandmother's funeral, she wouldn't have known that her grandmother's name was Li Shanlan. That day, the sky was blue and the air smelled of dirt after the fresh rain, and her grandmother called her to her bed and told her to keep going to school no matter what.

"The baby is a hard-working child, grandma has no ability, and the baby can't be like me. Xiao An, you were born with a weak family, and you can't rely on others, so we have to have our own skills to live a good life. Promise grandma that you must read more books and go to that ...... University. Don't worry about them when the time comes, how they love it, we can do it on our own. ”

"The baby is about to have a birthday, grandma is useless, she can't even cook longevity noodles, so she made this little rabbit for you, do you look good?"

Ji Si'an recalled those bits and pieces with tears in his eyes. She is really a person with thin relatives, and her grandmother left not long after her birthday. Her birthday is really not an auspicious day, if it weren't for her grandmother holding on to .......

"Okay, that's all the suspects I investigated at the time, and I'll write them all...... Down. Yuan Mu turned around and saw Ji Si'an's eyes red and tears streaming down her face, and she was speechless for a while.

Ji Si'an noticed his gaffe, picked up a tissue and wiped his face indiscriminately. "Nothing remembers the past."

"By the way, I was an eyewitness. Didn't they ask me? How I said it. Ji Si'an looked at Yuan Mu expectantly, she wanted to find some clues from her words back then.
