Things that solve crimes

"I have a question," Guo Chengyi quickly chewed off a large piece of roast goose in his hand, threw the bones away and continued.

"The deceased were two big men. They were killed with one knife. There were no other injuries on their bodies."

"How did the murderer do it when he committed the murder? Normally, people resist when they encounter danger."

"During the course of resistance, the murderer would definitely use the murder weapon again, but both victims had only one fatal wound."

"Another point is that both of the deceased were adult males. When faced with a murderer, it is unlikely that both of them will be unable to escape."

"So is there not just one murderer, but a gang?"

Wang Jiaduan touched another apple and took a few bites. "In fact, medicine can also be used. Pour the medicine on people first, and then kill people and set fire."

Sun He retorted, "No drug reaction was detected in the bodies of the two deceased persons."

"Medicine does not necessarily work if you eat it. You can also smell it." Seeing several people's puzzled looks, Qin Henian explained, "Do you know Datura flowers?"

"Burning dried datura flowers can cause coma."

"Used in small amounts, this flower can relieve coughs, asthma, analgesia and anesthesia, and it can also be used to make sweat medicine."

"Not only datura, but also several Chinese medicinal materials can make you faint when you smell it."

"Now we have two clues. One is a gang crime. This requires investigating the interpersonal relationship between the deceased. Guo Chengyi is responsible for investigating."

"One is the medicine Qin mentioned. Wang Jiaduan, please lead people to investigate this aspect." Sun He concluded.

He asked again, "Everyone, do you have anything else to add?"

Qin Henian said, "One more thing. We just talked about the lock issue."

"Both traces are present, indicating that the murderer opened the door with a key first, then found that the door could not be opened, and then pried the door open."

"Generally, if you can't open a door with a key, it's the one who has a key, so check the key master in the county."

"However," he changed the topic again, "after seven years, the master who assigned the key may not be able to remember it."

He said this in a tactful way. The master had assigned hundreds or thousands of keys, so how could he remember every one of them, let alone seven years ago.

"The murderer knows how to pick locks. Either he has a criminal record himself, or he learned it from others."

"The possibility of having a criminal record is very low. If he knew how to do it, he wouldn't be matching keys."

"It is very likely that the murderer asked someone to learn how to pick locks. It is impossible for serious lock masters to teach them. Only thieves can learn how to pick locks for money."

Hearing this, Sun He couldn't help but said, "We also thought of this possibility at the beginning. When we investigated the thieves, no one admitted it."

"Then check those who have been there before and after the crime, especially those who have criminal records themselves." Qin Henian said.

Being a thief is not that easy. He can teach others. Not to mention being the king of thieves, his skills are quite good.

If you want to have good skills, you must first "learn" for a period of time.

I'm not bragging, 90.00% of people who come out after "learning" can double their skills.

Hearing this, Sun and Tuan Kong shrank slightly. Back then, they had caught all the thieves in the county, and even expanded their scope to the entire city, but found nothing.

At that time, they did forget that there was another group of people.

After finishing all the remaining food, the group of people split up.

Sun He took Qin Henian to the prison. As he drove, he said, "There is someone who knows the situation of his colleagues very well."
