The night was silent.
The next day, after Su Mi had breakfast, he rode his electric bike to the Xianghe Police Station at 7:30 am.
After parking the car, Su Mi walked into the police station.
"Hello, Advisor Su!" "Good morning, Advisor Su!"
"Hello!"
Along the way, all the police officers greeted Su Mi politely. Although some people might think that Su Mi was young and that he was lucky to catch the murderer, he was invited back by the bureau chief after all. Moreover, he was valued by Liu Xie, so everyone did a good job on the surface.
Although Su Mi didn't care about what the ordinary police officer thought of him, he wasn't so cold that he wouldn't reply to anyone who greeted him. Therefore, he responded softly with a smile on his face.
Zhou Qian 'an had already arrived, but she was sitting in her seat, bored, waiting for Su Mi's arrival!
"Su Mi, you're here!"
Seeing Su Mi walk in, Zhou Qian 'an immediately went up to him.
Looking at Zhou Qian 'an who was obviously worried, Su Mi frowned and asked," What's the situation?" Did they not find any evidence?”
" Since we came back yesterday, we've requested a search warrant. We went to He Qiming's house at night and brought He Zhi back!" Zhou Qian 'an replied.
However, the most useful evidence we found was He Zhi's clothes hanging on the hanger. There was a faint trace of gasoline on one of his pants, but this could not be used as evidence to convict He Zhi!
He Zhi, on the other hand, looked scared when he saw us police officers. He kept asking for his father and completely ignored our questions!
He Qiming also insisted that He Zhi was the one who got the gasoline from playing at home!”
When Su Mi heard Zhou Qian 'an's answer, he knew how troublesome the matter was. It seemed that the father and son had colluded overnight.
"Xiao Zhao, Xiao Tao, pack your things and let's go to He Qiming's house again. I don't believe that I can't find other evidence!" At this time, Liu Xie walked over and shouted.
"Hmm? Advisor Su, you're here?"
Liu Xie greeted.
Su Mi glanced at him and shook his head." You didn't find it the first time. That means you didn't leave any important evidence."”
"Do you think a seven or eight-year-old child would set four fires in a row without leaving a trace?" Zhou Qian 'an asked.”
"No matter what, I'll ask him!" Su Mi said in a deep voice.”
Half an hour later, in the interrogation room.
Su Mi looked at the 18-year-old young man in front of him. At this moment, he was curled up in fear and looked at the ground evasively. He was full of vigilance against the unfamiliar dark environment around him.
Seven or eight years old mentally? I don't think so.
"He Zhi, do you still remember your mother?" Su Mi asked.”
He Zhi glanced at Su Mi and realized that it was someone else asking. Then, he lowered his head and played with his fingers again.
Su Mi was not annoyed and continued,"You should miss your mother very much, right?" The mother in your memories was so kind and kind, but because of a fire, your mother left you!”
He Zhi finally stopped playing with his fingers and looked up at Su Mi with a stubborn expression.
Su Mi looked at his glasses and continued,"You think it's your own fault that caused your mother to die!" So you're full of guilt, and you can't stand others talking bad about your mother, right?”
From Su Mi's point of view, He Zhi's eyes were filled with anger, as well as the fear of a child who had his little secret exposed.
Su Mi then noticed another detail. He Zhi's left hand was pressed on his right hand, and his hands were rubbing each other.
That was…
Because of nervousness?
Wait a minute!
Su Mi suddenly thought of a detail. Why couldn't the murderer's fingerprints be found at the four crime scenes? Was it because the murderer was very careful?
Only now did Su Mi think of another answer, which was that the murderer did not have fingerprints at all.
Su Mi remembered He Zhi being in a fire when he was ten years old. Although he was saved by the firefighters, he had minor burns all over his body. Could it be that there were also burns on his hands?
Then everything made sense!
"He Zhi, what happened to your hand? Is it itchy, or do you want to hit me?" Su Mi narrowed his eyes and asked in a frivolous tone.
He Zhi slammed his hands on the table and gritted his teeth as he stared at Su Mi." You're a bad person! I don't want to talk to you!"”
……
Su Mi came out of the interrogation room and saw Zhou Qian 'an and Liu Xie walking over.
"Bring your weapons and let's go to the third crime scene. I think I might have found the key evidence!”Su Mi said in a relaxed tone.
The two of them looked at each other. Although they were a little puzzled, they still took their things and followed Su Mi.
On the way, Zhou Qian 'an couldn't help but be curious." Su Mi, what kind of evidence is it?" she asked.”
Su Mi didn't want to play dumb. He said directly," At that time, we were all wondering why He Zhi could commit four consecutive crimes without leaving a trace. He didn't even leave a single fingerprint.
It wasn't until just now that I realized that it wasn't that he didn't leave any fingerprints, but that he didn't have any fingerprints at all!
"I saw his hands just now. It's obvious that his hands have recovered from burns. Burn injuries are not like knife wounds. After recovery, they usually eat spicy food, or when the body's atmosphere or blood flow increases, they will develop small blisters. Just now, I saw He Zhi unable to resist the blisters and scratching his hands!”
"What does this have to do with us finding the key evidence?" Liu Xie nodded and asked.”
