Hong Qifeng returned to the bureau, sat alone in the office and made a cup of tea, and began to look at the photos taken at the scene.

All photos show that the room was clean and tidy.

"Did someone clean it or did Mrs. Han clean it before she died?" This thought lingered in Hong Qifeng's mind.

He looked at the photos of the scene repeatedly, and there was a photo of a windowsill with faint cat footprints on it.

It seems that the neighbor and Wang Shangwei are not wrong, Mrs. Han does have a cat, but where has the cat gone now?

When he was about to leave the scene, he arranged for a few young people to look for the cat, and he didn't know what was going on now.

Hong Qifeng felt that the case seemed to be getting more and more complicated, and according to his experience, judging from the environment at the scene, it was indeed in line with the performance of suicide.

But how to explain the distance of the body from the ground? Could it be that someone is holding Mrs. Han down there and putting her head into the rope? But the corpse at the scene did not show any signs of struggle.

And what was the knife that appeared next to the corpse for?

There is one more doubt. Hong Qifeng thought about it based on experience: no items such as suicide notes were found at the scene.

In general suicide cases, there will be some last words or relics, which the deceased has something to say to his relatives and friends before his death. Mrs. Han obviously has a son, if she really committed suicide, she didn't leave a word for her son?

This question seems to be asked to Mrs. Han's son.

Hong Qifeng raised his wrist and looked at his watch, it had been three hours since he came back from the scene, and Liu Haoran had not come back to report, indicating that the visit was not smooth.

He has been a criminal policeman for many years, and he is very sure that the experience has brought him a hunch: the key point of this case may be in Mrs. Han's son.

Just as he could think of this, there was a commotion outside the office, and before he could calm down, there was a knock on the door.

"Team Hong, I've found it."

Hong Qifeng raised his head, it was a few young criminal policemen who were arranged by him to find the cat in the morning.

One of them was holding a gray cat in his hand, which was large and fat.

"Well, that's good." Hong Qifeng motioned for them to come in: "Where did you find it?" ”

The young detective holding the cat hurriedly said: "We walked around the house a few times, and then I guessed that the weather was so hot, the cat must be hiding in some shady place, so I focused on finding a shady place nearby." ”

Hong Qifeng nodded and smiled: "Did you guess right?" ”

The young detective nodded excitedly: "Hmm! Finally, I found it in the awning under the window on the second floor, and I found something to eat and lure it down before catching it. ”

"Are you sure this is Mrs. Han's cat?"

"It's not wrong, we asked the neighbors in Bali Lane, and everyone basically confirmed that this is the cat from Mrs. Han's house."

The young detective explained: "Wei Yushui, the owner of the grocery store downstairs, is very sure that it was he who went to the grocery store to steal his dog's dog food. ”

"Stealing dog food?"

"Yes, and I'm chased all over the place by dogs. In the end, he was entangled in a fishing line and almost bit his dog. After Wei Yushui grabbed it, he helped him cut the fishing line around his neck before letting him go. ”

Hong Qifeng approached the cat and looked at it, it was indeed a gray cat.

At a glance, I knew that he was usually well raised, slightly chubby, smooth coat, and looked very docile, with yellow-green eyes rolling slowly, observing the people in front of him unhurriedly.

Hong Qifeng nodded and asked the young criminal policeman holding the cat, "What's your name?" ”

"Li Yunbai, Muzi Li, Baiyun is the other Yunbai."

"Didn't you ask Wei Yushui, does this cat often go to his house to steal food?"

"I also asked him about this, and he said that no, in the past, cats sometimes jumped off the sun board on the roof, but they all ran straight away from his house, and this was the first time they stole dog food."

"Then this time it must be after Mrs. Han died, this cat had nothing to eat, so she took the risk to steal dog food." Hong Qifeng smiled slightly.

After thinking for a while, he said to Li Yunbai: "Xiao Li, a few of you go and get something for this cat to eat, and then send it to the forensic doctor and let them see if there is any evidence on the cat." ”

"Yes." Li Yunbai replied, hugged the cat, and led several other colleagues away.

Hong Qifeng nodded secretly, among this group of young probationary criminal policemen, Liu Haoran and this Li Yunbai, who dared to approach the corpse at the scene, should be two good seedlings.

These two young men, one is bold and daring, and the other is quite delicate. They all have specialties and can be cultivated well.

Thinking of this, he couldn't help but be a little anxious: Liu Haoran took a colleague to check on Mrs. Han's son, and he hasn't come back yet.

He walked around the office and was about to go out and call Officer Qin, who was bringing the newcomer, to contact Liu Haoran.

As soon as I walked out of the office, I heard a voice shouting outside: "Team Hong, someone has brought it back." ”

Hong Qifeng glared at him and said in a deep voice: "What are you shouting, don't scare him." ”

Liu Haoran was glared at by him, scratched the back of his head embarrassedly, stopped in place and whispered, "Take it to the conversation room?" ”

Hong Qifeng shook his head: "Send it to the conference room first and wait for a while, I'll go over immediately." ”

"Yes."

Hong Qifeng turned around and returned to the office, picked up the phone, and dialed He Mo from the forensic identification center: "Director He, I am Hong Qifeng, what is the situation with the body that was transported back in the morning?" ”

He Mo is the backbone of the forensic identification center and a very good forensic doctor, and she led the team to collect evidence at the scene in the morning.

"According to the procedure, an autopsy can't be done now," He Mo paused for a moment and continued: "At present, the evidence from the appearance of the corpse is observed, which is consistent with the characteristics of mechanical asphyxiation death. Moreover, no obvious mechanical injuries and incision or puncture wounds were noted. ”

"What else?"

"There are also corpses that have appeared in the Giant View, but no eggs of corpse-loving insects have been found, and the time of death should be within 3-5 days."

After a pause, He Mo said again: "By the way, the only point of physical injury is that there are some abrasions on the front side of both knees, but they are very slight, not like they were left by the cause of violence before death." ”

He Mo's resolute style of doing things told him everything Hong Qifeng wanted to ask at once.

But this made Hong Qifeng even more suspicious, he believed in He Mo's professionalism, since her initial judgment was self-hanging, the cause of death should not be wrong.

But how to explain those two doubts?

Hong Qifeng put down the phone, thought about it, or asked Mrs. Han's son first to see if there was any breakthrough.

At this moment, Officer Qin sent the basic household registration information of the deceased Mrs. Han over, and he took a cursory look at it on the way to the conference room.

Mrs. Han's profile is very simple, 57 years old, graduated from university.

He has worked in the fishing tackle factory for 25 years and has a son named Han Sui.

There is no information about her husband and other relatives on the document, and she should have been widowed for many years.

When I walked to the door of the conference room, I was basically done.

Hong Qifeng closed the information and pushed the door in.

At first glance, he saw the middle-aged man sitting directly across from him.

Out of professional habit, he looked at it before he spoke.

This middle-aged man has long and narrow eyes, slightly bald, and is thin, and his facial features are a little similar to Mrs. Han's.

The middle-aged man was chatting with Liu Haoran, and when he saw Hong Qifeng coming in, both of them stood up.

Hong Qifeng motioned for them to sit down, sat down next to him himself, and asked, "You are Han Sui, right?" ”

"Is it the fishing tackle factory where your mother used to work?"

"Yes. How do you know? Han Sui was stunned for a moment before answering.

Hong Qifeng raised the folder in his hand and said, "Public security organs, there are no secrets here. ”

Han Sui nodded and glanced at the folder in Xiang Hong Qifeng's hand.

Hong Qifeng looked at Han Sui's face and asked, "Speaking of your mother, when was the last time you saw her?" ”

Han Sui was stunned for a moment, and then said, "Last Saturday." After speaking, he looked at Hong Qifeng suspiciously: "What's wrong with my mother?" ”

Hong Qifeng didn't answer him, but continued to ask: "Last Saturday, that is, June 20th, 4 days ago, right?" ”

Han Sui was a little uneasy, but still answered the question: "Yes, my mother has lived alone in Bali Lane for many years, and I am usually busy, so I have little time to see her." Last Saturday, I went to see her, and I actually wanted to ask her if she would like to go back to live with us. ”

"Why do you suddenly want your mother to live with you?" Hong Qifeng was a little curious.

Han Sui rubbed his hands and said, "She is old, and we also want her to go back to live with us so that she can take care of her." ”

"Did she agree?"

"Nope." After speaking, Han Sui suddenly raised his head, widened his eyes and asked, "Why do you always ask about my mother?" Did something happen to my mom? Did she get sick or fall? Tell me! ”

Hong Qifeng sighed, clenched his hands into fists, pressed them against his chin, and said softly: "You have to be mentally prepared, your mother has passed away." ”
