When everyone saw Su Yan drawing Ye Shuigan's house, they didn't understand its purpose for a while.
Su Yan explained: "The wind was blowing from the south last night, and it was as strong as level 6 or 7. I believe all the villagers would put out the fire in front of the gate of Ye Shuigen's house on the south side."
Lu Haiping and everyone nodded.
"When a house burns, even if the fire is not big at first, if it is at a disadvantage, the thick smoke will be unbearable." Li Kejun explained.
Seeing that everyone understood this, Su Yan continued: "Because the villagers couldn't stand the smoke and fire, there was absolutely no one on the north side of Ye Shuigen's house, downwind of the back door."
Upon hearing this, everyone vaguely understood what Su Yan meant.
Li Kejun asked: "Officer Su, do you mean that the mysterious man took advantage of the wind and no one to transport straw in through the back door of Ye Shuigen's house?"
Su Yan put down the pen and nodded: "That's what I mean."
"But..." A young policeman in the crowd scratched his scalp, "But the villagers can't go downwind, so that person can go downwind? He still can't stand the smoke and fire!"
Everyone couldn't help laughing when they saw the young policeman refuting Su Yan.
"What's wrong? Isn't that the truth?" The young policeman was quite unconvinced when he saw everyone laughing at him.
Su Yan smiled and said, "Why do you think the fire brigade dared to go deep into the fire to rescue people?"
The policeman immediately said: "The fire brigade members have fire prevention measures, of course they dare..."
When the young policeman said this, his voice suddenly stopped. He looked at Su Yan with wide eyes: "You said that person also used fire prevention measures?"
Everyone couldn't help laughing, Li Kejun said: "Xiao Zhao, you don't understand until now?!"
Xiao Zhao had just started working at the police station, and his usual performance was pretty good, but when faced with detective masters like Su Yan, he seemed much immature.
"But..." Xiao Zhao blushed, but retorted: "But that person may not know that Ye Wen can set a fire. If Ye Wen doesn't set a fire, wouldn't his efforts to carry fire prevention measures be in vain?"
"That's a good question, Officer Zhao!" Su Yan immediately sat up straight and said in a deep voice: "That person came to the scene with fire prevention measures. He was obviously fully prepared, and his sinister intentions were clearly visible."
"What sinister intention?" Xiao Zhao asked doubtfully.
"That is, if Ye Wen hadn't set the fire, I believe this person would have helped Ye Wen set the fire to destroy the evidence. That's why I said this person had sinister intentions."
Only then did Xiao Zhao understand. He couldn't help but said in shock: "Officer Su, how did you deduce this? It's amazing!"
After listening to Su Yan's inference, not only Xiao Zhao admired him greatly, but also veteran investigators Lu Haiping also nodded frequently and said in agreement: "Xiao Su's analysis is very good. In this way, this person is also an accomplice and must be found out. !”
Su Yan added: "Since this person comes and goes freely in the village, I guess he must be a villager in this village."
Li Kejun and others also agreed with this statement. Li Kejun frowned and said: "It's just that there are thousands of adults in the village, who could be the suspect?"
"We can start with the suspect's fire protection equipment and find out where he got his fire protection equipment from? Most people don't have this." Xiao Zhao's eyes suddenly lit up and he said.
Su Yan nodded slightly: "This is a way."
When Xiao Zhao received Su Yan's affirmation, he immediately became excited. He turned around and asked Director Liang, "Who is in charge of fire protection in the village? This person is likely to have fire protection equipment, and he is also most likely to be a criminal suspect."
When Director Liang heard this, he couldn't help but smile bitterly: "I am the person in charge of fire protection in the village."
"..."
Xiao Zhao opened his mouth in surprise at first, and then looked Director Liang up and down with his eyes.
Could it be that Director Liang is the suspect?
Seeing Director Liang's embarrassment, Su Yan couldn't help but want to laugh. He said to Director Liang, "You are in charge of firefighting. Are there any fire prevention equipment issued?"
Director Liang shook his head and said: "This is just a false name. How come the higher-ups issue fire protection equipment?"
Li Kejun understood this very well, and immediately nodded and said: "It is true that the superiors do not issue them fire protection equipment. The reason why there are people in charge is to inform them if something happens."
Su Yan nodded: "That means that person bought his fire protection equipment from the market."
Li Kejun said: "That should be the case."
Su Yan immediately said to Lu Jiao: "Lu Jiao, please ask the city bureau to mobilize various police stations and ask them to investigate who has sold fire protection equipment on the market in the past few days."
Lu Haiping immediately said: "I will let Zhao Da handle it now. I believe there will be a result soon."
With that said, Lu Haiping went to the side and called Zhao Yang, the captain of the criminal police team.
After Lu Haiping's notification, everyone began to wait for the investigation results.
Because fire protection equipment is sold by specialized stores, such stores are all registered and their number is small, so it is easy to check.
Sure enough, the investigation soon yielded results. After Lu Haiping answered the phone, he told Su Yan and others: "There is a fire protection store on Xingfu Street that sold a set of fire protection equipment yesterday afternoon."
"Yesterday afternoon?" Everyone was overjoyed that the time was right.
"Have you found out who the person who made the purchase was?" Li Kejun asked immediately.
"It's a resident near the fire store..."
"Residents near the fire store?" Before Lu Haiping could finish speaking, everyone started talking in disappointment: "Aren't you from Jingcun?"
Seeing everyone's noisy discussion, Lu Haiping said helplessly: "You are too impatient. I haven't finished speaking yet."
Everyone immediately fell silent, and everyone looked at Lu Haiping nervously.
"The resident was also entrusted by someone. As for the person entrusted to him, he didn't know him. He only helped him buy it after the other person gave him a hundred yuan."
After listening to Lu Haiping's narration, Li Kejun said angrily: "Good guy, this person is quite insidious!"
Su Yan pondered: "Does that person look strange? He was afraid of attracting the attention of others, so he asked someone to buy it?"
Lu Haiping gave Su Yan a thumbs up and praised: "Xiao Su is still awesome. Yes, that person has a very unique appearance, which is unforgettable at a glance."
"Oh?" Everyone looked at Lu Haiping.
Lu Haiping said: "That man is a hunchback, and his hunchback is very severe. His head almost reaches his chest."
As soon as he finished speaking, before everyone had time to respond, Director Liang next to him exclaimed.
Su Yan immediately stared at Director Liang and asked in a deep voice: "Is there such a person in the village?"
Director Liang's face was uncertain. After a while, he nodded slowly: "I have a sixth uncle who has not yet received the Five Blessings. He is a hunchback. According to Lu Jiao's description, this person is probably him!"
When everyone heard this, they were overjoyed.
"Director Liang, take us to find him immediately!" Su Yan suddenly stood up and said to Director Liang in a deep voice.
Director Liang knew that this matter was of great importance, and of course he did not dare to protect him at this time. He immediately stood up and said, "Okay, I will take you there right now."
"Who is in your sixth uncle's family?" Su Yan asked Director Liang on the way.
"He belongs to a poor household with five guarantees and is alone." Director Liang replied.
Su Yan nodded.
Under the leadership of Director Liang, everyone quickly arrived at a brick house at the end of the village. The house was not big, but the exterior walls were painted very clean.
