Chapter 1835: The Evil Murderer

Recalling the past, when Zhao Yu was investigating the Beichuan demon case, he had entered the territory of Western Sichuan Province, but he had never been to Andu.

Andu, the capital of Western Sichuan Province, is the leading big city in Southwest my country.

When Zhao Yu arrived by high-speed rail, it was already ten o'clock in the evening.

Andu's climate is slightly hotter than Yaoming's, and it has already entered the rhythm of summer.

Because Zhao Yu didn't like to work hard because he had said hello in advance, only Zhang Ling, the criminal police captain in charge of the ghost king case of Andu Police Department, came to greet Zhao Yu and others this time.

Hearing this name before, Zhao Yu thought she was another female criminal police captain, but after meeting, she realized that Zhang Ling was not only a proper male captain, but also a middle-aged greasy uncle without a hair on his head. .

Nowadays, Zhao Yu has long been famous and resounded throughout the criminal investigation circle, so when the two sides met and introduced, Captain Zhang Ling was obviously a little nervous and cautious, and even a little bit afraid.

It is estimated that he has already heard of Zhao Yu's unique detective thinking, as well as his domineering and violent temper. Therefore, during the conversation, Zhang Ling always maintained a state of caution, for fear of saying something wrong and offending the detective.

However, Zhang Ling is also a smart person, he should have done his homework in advance, knowing that Zhao Yu doesn't like too much entertainment and politeness, so when Zhao Yu got in the car, he immediately started reporting to Zhao Yu.

"The name of the deceased is Niu Jinkui. He was a teacher at Tongle Art School. He specialized in teaching guqin." Zhang Ling's voice was loud and clear, as if he had learned broadcasting and hosting. , proficient in various musical instruments..."

"Oh?" Zhao Yu was slightly taken aback, "Another opera singer?"

"Sichuan Opera?" Cui Lizhu interrupted and asked, "Did you change your face?"

"Well... yes, face changing is just one of them..." Zhang Ling looked at Cui Lizhu, and didn't dare to linger on this young beauty with a beautiful face, so she continued to introduce, "Niu Jinkui has indeed performed on stage. , but most of them are small tricks, and his main job is still a musician!

"However, as a musician, he was also a well-known figure in our local area in the past, and he even appeared on CCTV's program! It's just that this person's character is not very good, and he got a criminal record for prostitution 10 years ago.

"Later, he had an affair with a married woman, and was caught on the spot. Since then, his reputation has plummeted. Not only did he get divorced, but he was also fired from the theater troupe. He could only go to school to teach guqin..."

"Oh..." Ran Tao nodded and said,

"It seems that this person is not a fuel-efficient lamp!"

"He lives alone now," Zhang Ling said, "so he hasn't been reported for so many days. The school only saw that he didn't go to work and called him, but the phone was turned off, and no further investigation was made...

"Also, the guqin at the scene of the crime is also Niu Jinkui's own!

"It is said that the Guqin is very valuable, it is a handmade Guqin..."

"Oh... so... have you searched the victim's home? Have you found anything?" Zhao Yu directly asked a professional question.

"We have searched," Zhang Ling replied hastily, "no suspicious traces were found in the deceased's home, and his mobile phone, wallet and other valuables were also missing, which means that the deceased's home was not the first scene, and he should have been kidnapped by the murderer outside. !"

"Oh..." Zhao Yu pondered for a moment, then asked again, "So, that temple is the first scene of the crime?"

"Yes!" Zhang Ling nodded and said, "It's the Guandi Temple. According to the forensic examination, it should be the scene of the first crime. The deceased was brought there by the murderer three nights ago, and then killed him!

"According to the autopsy report, the deceased died of TETS poisoning, which is what we often call tetramine. I believe..." Zhang Ling gestured to his mobile phone, "Have you read the report?"

"Hmm..." Zhao Yu nodded.

"The murderer definitely made sufficient preparations in advance," Zhang Ling said. "Tetramine has a very low solubility in water, but he used a chemical reagent containing acetone to dissolve tetramine, and then injected it with an injection. , injected into the digestive tract and respiratory tract of the deceased, accelerating the poisoning speed of the deceased!

"According to forensic estimates, the deceased should be dead in less than 15 minutes after being poisoned!

"If you consider Niu Jinkui's age and physical condition, perhaps the entire death process will take less than 5 minutes!"

As soon as these words came out, Zhao Yu immediately fell into deep thought.

Zhang Ling waited for a while, and saw that Zhao Yu was almost in deep thought, and then continued: "Tetramine is a strong poison, once used, accidents frequently occur, so in 1991, its production and sales were completely banned!

"After taking the poison, the symptoms are very serious, which can affect multiple systems of the human body, convulsions and vomiting, until loss of consciousness and body stiffness!

"The forensic doctor said," Zhang Ling said, "the victim had obvious signs of being tied up, and they suspected that when the deceased died of poisoning, he was tied up on the seat by the murderer.

"After a person dies, the body will immediately become stiff and cling to the seat, so after the person dies, the murderer untied the rope..."

"Wow..." Hearing this, Cui Lizhu couldn't help but said, "The murderer is evil enough, I feel that his brain must be sick!"

"Captain Zhang," Zeng Ke asked Zhang Ling at this time, "Have you found the files of Tao Yulan's case? Was the poison Tao Yulan used back then also Tetramine?"

"Hmm... well..." Zhang Ling looked at Zhao Yu uneasily, and then said, "The case of Tao Yulan happened in the early days of liberation. At that time, Andu was not the capital of western Sichuan Province, so the relevant files had to go to Chongyang City. Look over there!

"Well, the colleague over there is already looking for..."

After finishing speaking, Zhang Ling looked at Zhao Yu again, and after realizing that Zhao Yu didn't look angry, he continued with a sense of relief: "About the rat poison, it's definitely impossible.

"We checked the information. Tetramine was invented by a German scientist in 1949. By 1953, it hadn't become popular in our country, so...the poison Tao Yulan used must be something else!"

"After all, there are 66 years between the two cases..." Wu Xiumin said to Zhao Yu, "Leader, I think we should focus on this case first!"

"Hmm..." After Zhao Yu nodded, he asked Zhang Ling again, "What happened at the crime scene? Did you find any witnesses or surveillance video?"

"This... um..." Zhang Ling faltered for a moment, then said helplessly, "So far, no witnesses have been found. The area around the crime scene is a demolition area, and the monitoring equipment there has long been damaged!"

"Then... where's the driving recorder?" Ran Tao interrupted and asked.

"The demolition area is full of small alleys, cars can't get in at all, so the driving recorder doesn't work... We can only investigate through the surveillance on the outer roads and some shops, but we haven't got any clues yet..."

"Phew..." Zhao Yu exhaled, and said, "Just by using the syringe, it shows that the murderer has already prepared, and must have surveyed the terrain long ago!

"It seems... this time, we have encountered a master again!" Zhao Yu thought for a while, and said to Zhang Ling, "In this case, let's not go to the police station, and go directly to the scene!"
